自定义股票键盘

在开发股票App的时候可能会被要求使用股票键盘，前一阵从不炒股得人第一次听说了股票键盘，后来查阅了一下，其实就是自定义的键盘，奈何一只搜索股票键盘，难住了我，所以我写了一个股票键盘。

话不多说直接上马了：

首先要先写一个布局（就是在要显示键盘的类的布局里）：

<RelativeLayout        android:layout_width="match_parent"        android:layout_height="match_parent"        android:layout_alignParentBottom="true"        >            <android.inputmethodservice.KeyboardView                android:id="@+id/hot_keyboard_view"                android:layout_width="fill_parent"                android:layout_height="wrap_content"                android:background="@android:color/black"                android:focusable="true"                android:focusableInTouchMode="true"                android:keyTextColor="@color/white"                android:keyPreviewLayout="@layout/key_preview_layout"                />    </RelativeLayout>

其中KeyboardView键盘的控件。

接下来写一个键盘类：

import android.app.Activity;import android.content.Context;import android.inputmethodservice.Keyboard;import android.inputmethodservice.KeyboardView;import android.text.Editable;import android.view.View;import android.widget.EditText;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.RelativeLayout;import java.util.List;import cn.uniwa.uniwa.R;public class KeyBoardNumber {    private KeyboardView keyboardView;    private Keyboard k1;// 英文键盘    private Keyboard k2;// 数字键盘    private EditText ed;    boolean b = true;    Activity a;//接收传过来Activity    LinearLayout ll;    ImageView hotIvDel;    LinearLayout hotLlResult;    RelativeLayout hotRlNoFind;    public KeyBoardNumber(Activity act, Context ctx, EditText edit) {//Activity可以将使用到此键盘的类传过来，也可以删除不传        this.ed = edit;        a = act;        k1 = new Keyboard(ctx, R.xml.letter);        k2 = new Keyboard(ctx, R.xml.symbols);        keyboardView = (KeyboardView) act.findViewById(R.id.hot_keyboard_view);        keyboardView.setKeyboard(k2);        //软键盘是否启用        keyboardView.setEnabled(true);        //按键提示是否启用        keyboardView.setPreviewEnabled(false);        keyboardView.setOnKeyboardActionListener(listener);        List<Keyboard.Key> keylist = k1.getKeys();        for (Keyboard.Key key : keylist) {            if (key.label != null && isword(key.label.toString())) {                key.label = key.label.toString().toUpperCase();                key.codes[0] = key.codes[0] - 32;            }        }    }    private KeyboardView.OnKeyboardActionListener listener = new KeyboardView.OnKeyboardActionListener() {        @Override        public void swipeUp() {        }        @Override        public void swipeRight() {        }        @Override        public void swipeLeft() {        }        @Override        public void swipeDown() {        }        @Override        public void onText(CharSequence text) {        }        @Override        public void onRelease(int primaryCode) {        }        @Override        public void onPress(int primaryCode) {        }        @Override        public void onKey(int primaryCode, int[] keyCodes) {//注意！设置的键盘按钮可以再此方法内设置            ll = (LinearLayout) a.findViewById(R.id.hot_ll_text);            Editable editable = ed.getText();            int start = ed.getSelectionStart();            if (primaryCode == Keyboard.KEYCODE_CANCEL) {// 完成//                Toast.makeText(KeyBoardNumber.this,"ok+"+editable,Toast.LENGTH_LONG).show();//                hideKeyboard();            } else if (primaryCode == Keyboard.KEYCODE_DELETE) {// 回退                if (editable != null && editable.length() > 0) {                    if (start > 0) {                        editable.delete(start - 1, start);//                        hotIvDel.setVisibility(View.GONE);//                        hotLlResult.setVisibility(View.GONE);//                        ll.setVisibility(View.VISIBLE);//                        hotRlNoFind.setVisibility(View.GONE);                    }                }            } else if (primaryCode == -15) {                EditText ed = (EditText) a.findViewById(R.id.hot_et_search);//这些方法用不到可以删除，这是从使用键盘的activity传来的id                hotLlResult = (LinearLayout) a.findViewById(R.id.hot_ll_result);                hotRlNoFind = (RelativeLayout) a.findViewById(R.id.hot_rl_noFind);                String text = ed.getText().toString();               if (text.equals("")||text == null){                   hotIvDel.setVisibility(View.GONE);                   hotLlResult.setVisibility(View.GONE);                   ll.setVisibility(View.VISIBLE);                   hotRlNoFind.setVisibility(View.GONE);               }                hideKeyboard();//                ll.setVisibility(View.VISIBLE);//                ed.setText("");            } else if (primaryCode == 4896) {// 清空                editable.clear();            } else if (primaryCode == 002) {                editable.insert(start, "002");            } else if (primaryCode == 300) {                editable.insert(start, "300");            } else if (primaryCode == 600) {                editable.insert(start, "600");            } else if (primaryCode == 601) {                editable.insert(start, "601");            } else if (primaryCode == 000) {                editable.insert(start, "000");            } else if (primaryCode == 115) {                editable.insert(start, "S");            } else if (primaryCode == 8016) {//editable.insert(start, "16");                if (b) {                    keyboardView.setKeyboard(k1);                    b = false;                } else {                    keyboardView.setKeyboard(k2);                    b = true;                }            } else {                editable.insert(start, Character.toString((char) primaryCode));            }        }    };    public boolean isKeyBoardShow() {        int visibility = keyboardView.getVisibility();        if (visibility == View.GONE || visibility == View.INVISIBLE) {            return false;        } else {            return true;        }    }    public void showKeyboard() {        int visibility = keyboardView.getVisibility();        if (visibility == View.GONE || visibility == View.INVISIBLE) {            keyboardView.setVisibility(View.VISIBLE);        }    }    //隐藏键盘    public void hideKeyboard() {        int visibility = keyboardView.getVisibility();        if (visibility == View.VISIBLE) {            keyboardView.setVisibility(View.INVISIBLE);        }    }    private boolean isword(String str) {        String wordstr = "abcdefghijklmnopqrstuvwxyz";        if (wordstr.indexOf(str.toLowerCase()) > -1) {            return true;        }        return false;    }

注意看我写的注释应该就能明白了

接下来是英文键盘：

<?xml version="1.0" encoding="utf-8"?><Keyboard xmlns:android="http://schemas.android.com/apk/res/android"    android:keyWidth="10%p" android:horizontalGap="0px"    android:verticalGap="0px" android:keyHeight="8%p">    <Row>        <Key android:codes="113" android:keyEdgeFlags="left" android:keyLabel="Q"/>        <Key android:codes="119" android:keyLabel="W"/>        <Key android:codes="101" android:keyLabel="E"/>        <Key android:codes="114" android:keyLabel="R"/>        <Key android:codes="116" android:keyLabel="T"/>        <Key android:codes="121" android:keyLabel="Y"/>        <Key android:codes="117" android:keyLabel="U"/>        <Key android:codes="105" android:keyLabel="I"/>        <Key android:codes="111" android:keyLabel="O"/>        <Key android:codes="112" android:keyEdgeFlags="right" android:keyLabel="P"/>    </Row>    <Row>        <Key android:codes="97"   android:horizontalGap="4.999995%p" android:keyEdgeFlags="left" android:keyLabel="A"/>        <Key android:codes="115" android:keyLabel="S"/>        <Key android:codes="100" android:keyLabel="D"/>        <Key android:codes="102" android:keyLabel="F"/>        <Key android:codes="103" android:keyLabel="G"/>        <Key android:codes="104" android:keyLabel="H"/>        <Key android:codes="106" android:keyLabel="J"/>        <Key android:codes="107" android:keyLabel="K"/>        <Key android:codes="108" android:keyEdgeFlags="right" android:keyLabel="L"/>    </Row>    <Row>        <Key android:codes="122" android:horizontalGap="2%p" android:keyEdgeFlags="left" android:keyLabel="Z"/>        <Key android:codes="120" android:keyLabel="X"/>        <Key android:codes="99" android:keyLabel="C"/>        <Key android:codes="118" android:keyLabel="V"/>        <Key android:codes="98" android:keyLabel="B"/>        <Key android:codes="110" android:keyLabel="N"/>        <Key android:codes="109"  android:keyLabel="M"/>        <Key android:codes="-5"            android:isRepeatable="true"            android:keyEdgeFlags="right"            android:keyIcon="@drawable/sym_keyboard_delete"            android:keyWidth= "25%p"/>    </Row>    <Row>        <Key android:codes="8016"            android:keyLabel="123"            android:keyEdgeFlags="left"            android:keyWidth= "25%p"/>        <Key android:codes="4896"            android:isRepeatable="true"            android:keyWidth= "25%p"            android:keyLabel="@string/key_clear" />        <Key android:codes="-15"            android:isRepeatable="true"            android:keyWidth= "25%p"            android:keyLabel="隐藏" />        <Key android:codes="-3"            android:isRepeatable="true"            android:keyEdgeFlags="right"            android:keyLabel="@string/key_ok"            android:keyWidth= "25%p" />    </Row>    </Keyboard>

数字键盘：

<?xml version="1.0" encoding="utf-8"?><Keyboard xmlns:android="http://schemas.android.com/apk/res/android"android:keyWidth="20%p" android:horizontalGap="0px"android:verticalGap="0px" android:keyHeight="8%p"><Row>    <Key android:codes="600" android:keyLabel="600" /><Key android:codes="49" android:keyLabel="1" /><Key android:codes="50" android:keyLabel="2" /><Key android:codes="51" android:keyLabel="3" /><Key android:codes="-5" android:isRepeatable="true"     android:keyIcon="@drawable/sym_keyboard_delete" /></Row><Row>    <Key android:codes="601" android:keyLabel="601" /><Key android:codes="52" android:keyLabel="4" /><Key android:codes="53" android:keyLabel="5" /><Key android:codes="54" android:keyLabel="6" /><Key android:codes="4896" android:keyLabel="@string/key_clear" /></Row><Row>    <Key android:codes="000" android:keyLabel="000" /><Key android:codes="55" android:keyLabel="7" /><Key android:codes="56" android:keyLabel="8" /><Key android:codes="57" android:keyLabel="9" /><Key android:codes="-15" android:isRepeatable="true"android:keyLabel="隐藏" /></Row><Row>    <Key android:codes="8016" android:keyLabel="ABC" />    <Key android:codes="002" android:keyLabel="002" /><Key android:codes="48" android:keyLabel="0" /><Key android:codes="300" android:keyLabel="300" /><Key android:codes="-3" android:isRepeatable="true"android:keyEdgeFlags="right"android:keyLabel="@string/key_ok"/></Row></Keyboard>

两个键盘内的功能键的codes都是重复的，可以进行数字英文进行切换

以上键盘设置完毕，只要在Activity中使用即可：

private KeyBoardNumber keyBoard;

keyBoard = new KeyBoardNumber(act, mContext, hotEtSearch);

 hotEtSearch.setOnTouchListener(new View.OnTouchListener() {            @Override            public boolean onTouch(View view, MotionEvent motionEvent) {                int inputback = hotEtSearch.getInputType();//                hotEtSearch.setInputType(InputType.TYPE_NULL);                keyBoard.showKeyboard();                hotEtSearch.setInputType(inputback);                return false;            }        });

这样就会显示键盘了；

但还是要注意，键盘布局的显示和隐藏；
