我在这个大神的基础上修改的

复制以下代码，然后找个拼音jar包，就能出来效果了

注：有个问题我解决不了，当光标在文字中间的时候，@一个人，回来，光标就到了文本的最后了。我试过，改不了。如果有哪个大神知道怎么解决，请告我一下，谢谢了。

排序需要的jar包（pinyin4j-2.5.0.jar），我上传失败了。如果有需要，网上找个，或者加我qq：2904530975，我发

效果图（不会搞动态的，就用静态的了）：

2、MainActivity

package com.chen.demo;import android.app.Activity;import android.content.Intent;import android.graphics.Color;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.ImageView;public class MainActivity extends Activity {    MentionEditText mention_et;    ImageView person_iv;    /**     * 点击@符号记录当前光标位置的变量     */    int tempIndex = -1;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mention_et = (MentionEditText) findViewById(R.id.mention_et);        person_iv = (ImageView) findViewById(R.id.person_iv);        //设置被@的人的名字展示的颜色        mention_et.setMentionTextColor(Color.parseColor(Chen.nameColor));        //设置匹配规则        mention_et.setPattern(Chen.regex);        //监听文本长度        mention_et.setTextLengthlistener(new MentionEditText.TextLengthlistener() {            @Override            public void onTextLength() {            }        });        //监听软键盘输入@符号        mention_et.setOnMentionInputListener(new MentionEditText.OnMentionInputListener() {            @Override            public void onMentionCharacterInput() {                tempIndex = mention_et.getSelectionStart();                Log.e("in_keyboard_tempIndex", tempIndex + "");                //startActivityForResult(Intent intent, int requestCode)                startActivityForResult(new Intent(MainActivity.this, AttentionPersonActivity.class), 111);            }        });        //监听@人的个数        mention_et.setAttentionPersonNumListener(new MentionEditText.AttentionPersonNumListener() {            @Override            public void onPersonNum() {            }        });        //点击软键盘外的@符号        person_iv.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                tempIndex = mention_et.getSelectionStart();                Log.e("out_keyboard_tempIndex", tempIndex + "");                startActivityForResult(new Intent(MainActivity.this, AttentionPersonActivity.class), 222);            }        });    }    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        if (requestCode == 111 && resultCode == 456456) {            //点击软键盘上的@符号回来的            String text = mention_et.getText().toString();            String name = data.getStringExtra("name");            if (tempIndex == 0) {                text = name + " " + text;            } else if (tempIndex == text.length()) {                text = text + name + " ";            } else {                String s1 = text.substring(0, tempIndex);                String s2 = text.substring(tempIndex, text.length());                text = s1 + name + " " + s2;            }            mention_et.setText(text);        }        if (requestCode == 222 && resultCode == 456456) {            //点击键盘外的@符号            String text = mention_et.getText().toString();            String name = data.getStringExtra("name");            if (tempIndex == 0) {                text = "@" + name + " " + text;            } else if (tempIndex == text.length()) {                text = text + "@" + name + " ";            } else {                String s1 = text.substring(0, tempIndex);                String s2 = text.substring(tempIndex, text.length());                text = s1 + "@" + name + " " + s2;            }            mention_et.setText(text);        }        super.onActivityResult(requestCode, resultCode, data);    }}

3、MainActivity的布局很简单：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"              xmlns:tools="http://schemas.android.com/tools"              android:layout_width="match_parent"              android:layout_height="match_parent"              android:orientation="vertical"              tools:context=".MainActivity">    <com.chen.demo.MentionEditText        android:id="@+id/mention_et"        android:layout_width="match_parent"        android:layout_height="200dp"        android:layout_margin="10dp"        android:gravity="top|left"        android:hint="说点什么吧"        android:textSize="20sp"/>    <ImageView        android:id="@+id/person_iv"        android:layout_width="50dp"        android:layout_height="50dp"        android:layout_gravity="center_horizontal"        android:layout_marginTop="30dp"        android:background="@mipmap/link"/></LinearLayout>

4、第二个activity需要的东西准备
4.1

public class Chen {    //在Edittext中匹配人的名字。名字中允许出现 _ - 汉字 数字 英文 数字。且出现次数是在1-30之间。    public static String regex="@[_-\\u4E00-\\u9FA5\\w]{1,30}";    public static String nameColor="#3a76a6";}

4.2、

public class Utils {    private static Toast toast;    public static void showSingleToast(Context context, String msg){        if(toast == null){            toast = Toast.makeText(context, "", Toast.LENGTH_SHORT);        }        toast.setText(msg);        toast.show();    }    /**     * 检查字符串是否是空     *     * @param str     * @return true:字符串为空     */    public static boolean checkStringIsEmpty(String str) {        if (TextUtils.isEmpty(str) || "null".equals(str)) {            return true;        } else {            return false;        }    }}

4.3、

/** * chenjianqiang * 选择关注人的回调接口 */public interface SelectAttentionPersonListener {    void personData(String name);}

5、PersonBean，要注意它实现的接口和最后的排序

package com.chen.demo;public class Person implements Comparable<Person>{    private String name;    private String pinyin;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getPinyin() {        return pinyin;    }    public void setPinyin(String pinyin) {        this.pinyin = pinyin;    }    @Override    public int compareTo(Person another) {        return pinyin.compareTo(another.pinyin);    }}

6、PinYinUtil

package com.chen.demo;import net.sourceforge.pinyin4j.PinyinHelper;import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType;import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat;import net.sourceforge.pinyin4j.format.HanyuPinyinToneType;import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination;public class PinYinUtil {    public static final String aa = "[0-9]";    public static String regex = "[-_a-z0-9`~!@#$%^&*()+=|{}':;',\\[\\].<>~！@#￥%……&*（）——+|{}【】‘；：”“’。，、？ ]";    /**     * 获取指定字符串的拼音     * @param strs     * @return     */    public static String getPinyin(String strs) {        HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();        format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);        format.setCaseType(HanyuPinyinCaseType.UPPERCASE);        StringBuilder sb = new StringBuilder();        char[] charArray = strs.toCharArray();        for (int i = 0; i < charArray.length; i++) {            char c = charArray[i];            String s=c+"";            // 跳过空格和#            if(Character.isWhitespace(c)||s.matches(regex)){                continue;            }            // 直接添加特殊字符\字母\数字            if(c >= -128 && c < 127){                sb.append(c);            }else {                // 可能是汉字                try {                    String str = PinyinHelper.toHanyuPinyinStringArray(c, format)[0];                    sb.append(str);                } catch (BadHanyuPinyinOutputFormatCombination e) {                    e.printStackTrace();                }            }        }        return sb.toString();    }}

7、QuickIndexBar（快速索引自定义控件）

package com.chen.demo;import android.content.Context;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.graphics.Rect;import android.util.AttributeSet;import android.view.MotionEvent;import android.view.View;/** * 快速索引 * chenjianqiang */public class QuickIndexBar extends View {    public interface OnLetterUpdateListener {        void onLetterUpdate(String letter);    }    private OnLetterUpdateListener onLetterUpdateListener;    public OnLetterUpdateListener getOnLetterUpdateListener() {        return onLetterUpdateListener;    }    public void setOnLetterUpdateListener(            OnLetterUpdateListener onLetterUpdateListener) {        this.onLetterUpdateListener = onLetterUpdateListener;    }    private static final String[] LETTERS = new String[]{"#", "A", "B", "C", "D",            "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q",            "R", "S", "T", "U", "V", "W", "X", "Y", "Z"};    private Paint paint;    private int cellWidth;    private int mHeight;    private float cellHeight;    public QuickIndexBar(Context context) {        this(context, null);    }    public QuickIndexBar(Context context, AttributeSet attrs) {        this(context, attrs, 0);    }    public QuickIndexBar(Context context, AttributeSet attrs, int defStyle) {        super(context, attrs, defStyle);        paint = new Paint(Paint.ANTI_ALIAS_FLAG);        //        paint.setColor(Color.parseColor("#7e7e7e"));        paint.setColor(Color.parseColor("#7e7e7e"));        // 字体加粗        //        paint.setTypeface(Typeface.DEFAULT_BOLD);        //单位是像素        paint.setTextSize(50);    }    @Override    protected void onDraw(Canvas canvas) {        // 将A-Z绘制到界面上        for (int i = 0; i < LETTERS.length; i++) {            String letter = LETTERS[i];            // 计算x ， y坐标            float x = cellWidth / 2.0f - paint.measureText(letter) / 2.0f;            Rect bounds = new Rect();            paint.getTextBounds(letter, 0, letter.length(), bounds);            int textHeight = bounds.height();            float y = cellHeight * 0.5f + textHeight * 0.5f + i * cellHeight;            //            paint.setColor(i == currentIndex ? Color.GRAY : Color.WHITE);            canvas.drawText(letter, x, y, paint);        }    }    private int currentIndex = -1;    @Override    public boolean onTouchEvent(MotionEvent event) {        int index = -1;        switch (event.getAction()) {            case MotionEvent.ACTION_DOWN:                index = (int) (event.getY() / cellHeight);                if (index >= 0 && index < LETTERS.length) {                    if (currentIndex != index) {                        String letter = LETTERS[index];                        if (onLetterUpdateListener != null) {                            onLetterUpdateListener.onLetterUpdate(letter);                        }                        currentIndex = index;                    }                }                break;            case MotionEvent.ACTION_MOVE:                index = (int) (event.getY() / cellHeight);                if (index >= 0 && index < LETTERS.length) {                    if (currentIndex != index) {                        String letter = LETTERS[index];                        if (onLetterUpdateListener != null) {                            onLetterUpdateListener.onLetterUpdate(letter);                        }                        currentIndex = index;                    }                }                break;            case MotionEvent.ACTION_UP:                currentIndex = -1;                break;            default:                break;        }        invalidate();        return true;    }    @Override    protected void onSizeChanged(int w, int h, int oldw, int oldh) {        super.onSizeChanged(w, h, oldw, oldh);        cellWidth = getMeasuredWidth();        mHeight = getMeasuredHeight();        cellHeight = mHeight * 1.0f / LETTERS.length;    }}

8、第二个activity的布局attention_person_activity

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"                xmlns:tools="http://schemas.android.com/tools"                android:layout_width="match_parent"                android:layout_height="match_parent"                tools:context=".MainActivity">    <ListView        android:id="@+id/listview"        android:layout_width="match_parent"        android:layout_height="match_parent"/>    <com.chen.demo.QuickIndexBar        android:id="@+id/quick_index_bar"        android:layout_width="20dp"        android:layout_height="match_parent"        android:layout_alignParentRight="true"        android:layout_marginBottom="15dp"        android:layout_marginRight="15dp"        android:layout_marginTop="15dp"        /></RelativeLayout>

9、展示人的Adapter引用的item布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"              android:layout_width="match_parent"              android:layout_height="match_parent"              android:orientation="vertical">    <TextView        android:id="@+id/tv_index"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="#f6f6f6"        android:gravity="center_vertical"        android:paddingBottom="5dp"        android:paddingLeft="15dp"        android:paddingTop="5dp"        android:text="Z"        android:textColor="#ff0000"        android:textSize="15sp"        />    <TextView        android:id="@+id/tv_name"        android:layout_width="match_parent"        android:layout_height="50dp"        android:gravity="center_vertical"        android:paddingLeft="15dp"        android:text=""        android:textSize="20sp"/></LinearLayout>

10、NameAdapter（这里简单写了，没有加viewholder。实际是需要的）

package com.chen.demo;import android.text.TextUtils;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;import java.util.ArrayList;public class NameAdapter extends BaseAdapter {    private final ArrayList<Person> list;    private SelectAttentionPersonListener listener;    public NameAdapter(ArrayList<Person> list, SelectAttentionPersonListener listener) {        this.list = list;        this.listener = listener;    }    @Override    public int getCount() {        return list.size();    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        View view;        if (convertView == null) {            view = View.inflate(parent.getContext(), R.layout.item_list_name, null);        } else {            view = convertView;        }        TextView tv_name = (TextView) view.findViewById(R.id.tv_name);        TextView tv_index = (TextView) view.findViewById(R.id.tv_index);        Person person = list.get(position);        final String name = person.getName();        String currentIndexStr = person.getPinyin().charAt(0) + "";        String indexStr = null;        // 经过判断进行indexStr赋值        if (position == 0) {            // 1. 是首位            indexStr = currentIndexStr;        } else {            // 2. 当前首字母和上一个不一致            String lastBeanPinYin = list.get(position - 1).getPinyin();            String lastIndexStr = lastBeanPinYin.charAt(0) + "";            if (!TextUtils.equals(lastIndexStr, currentIndexStr)) {                // 不一致， 把当前字母赋给indexStr                indexStr = currentIndexStr;            }        }        tv_index.setVisibility(indexStr != null ? View.VISIBLE : View.GONE);        tv_index.setText(currentIndexStr);        tv_name.setText(name);        tv_name.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                listener.personData(name);            }        });        return view;    }    @Override    public Object getItem(int position) {        return null;    }    @Override    public long getItemId(int position) {        return 0;    }}

11、AttentionPersonActivity

package com.chen.demo;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.text.TextUtils;import android.widget.ListView;import java.util.ArrayList;import java.util.Collections;public class AttentionPersonActivity extends Activity implements SelectAttentionPersonListener {    ListView listview;    ArrayList<Person> list;    NameAdapter nameAdapter;    QuickIndexBar quick_index_bar;    ArrayList<String> nameList;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.attention_person_activity);        listview = (ListView) findViewById(R.id.listview);        quick_index_bar = (QuickIndexBar) findViewById(R.id.quick_index_bar);        list = new ArrayList<>();        nameList = new ArrayList<>();        nameList.add("123456");        nameList.add("哈哈哈");        nameList.add("123哈哈");        nameList.add("哈哈456");        nameList.add("abcdef");        nameList.add("abc哈哈");        nameList.add("哈哈def");        nameList.add("ABC哈哈");        nameList.add("哈哈ABC");        nameList.add("得****得得");        nameList.add("_我们");        nameList.add("你们");        nameList.add("盖聂");        nameList.add("漩涡鸣人");        nameList.add("卡卡西");        nameList.add("鼬神");        nameList.add("佐助。");        nameList.add("雏.田");        nameList.add("=日=向=");        nameList.add("-斑");        nameList.add("三井寿");        nameList.add("小贤");        Person person;        String name;        for (int i = 0; i < nameList.size(); i++) {            person = new Person();            name = nameList.get(i);            person.setName(name);            //如果名字对应的拼音解析到了空值，就给个#号            if (!Utils.checkStringIsEmpty(PinYinUtil.getPinyin(name))) {                person.setPinyin(PinYinUtil.getPinyin(PinYinUtil.getPinyin(name)));            } else {                person.setPinyin("#");            }            list.add(person);        }        Collections.sort(list);        //第二个参数是回调接口        nameAdapter = new NameAdapter(list, this);        listview.setAdapter(nameAdapter);        quick_index_bar.setOnLetterUpdateListener(new QuickIndexBar.OnLetterUpdateListener() {            @Override            public void onLetterUpdate(String letter) {                Utils.showSingleToast(AttentionPersonActivity.this, letter);                for (int i = 0; i < list.size(); i++) {                    String indexStr = list.get(i).getPinyin().charAt(0) + "";                    if (TextUtils.equals(indexStr, letter)) {                        // 匹配成功                        //如果快速索引的最上面不是#，直接就是A开头，就不用+1了                        listview.setSelection(i);                        break;                    }                }            }        });    }    @Override    public void personData(String name) {        Intent intent = new Intent(this, MainActivity.class);        intent.putExtra("name", name);        //setResult(int resultCode, Intent data)        setResult(456456, intent);        finish();    }}

12、最后清单文件中（android:screenOrientation是禁止屏幕旋转的）

    <activity       android:name=".AttentionPersonActivity"       android:screenOrientation="portrait"       />
