1，首先这个类是绘制右侧自定义索引条的：
/** * Created by felix on 15/4/24. */public class QuickIndexBar extends View { public QuickIndexBar(Context context) { super(context); init(); } public QuickIndexBar(Context context, AttributeSet attrs) { super(context, attrs); init(); } public QuickIndexBar(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); init(); } //以26个字母作为索引 String[] indexs = 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, cellHeight; private void init() { paint = new Paint(); paint.setTextSize(10); paint.setColor(Color.RED); //paint.setTypeface(Typeface.DEFAULT_BOLD); paint.setAntiAlias(true); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); if (cellHeight == 0) cellHeight = getMeasuredHeight() / indexs.length; if (cellWidth == 0) cellWidth = getMeasuredWidth(); //分别画26个字母 for (int i = 0; i < indexs.length; i++) { if (i == lastIndex) { //正在touch的位置 需要更加人性化的交互 paint.setTextSize(80); paint.setColor(Color.GRAY); } else { paint.setTextSize(40); paint.setColor(Color.BLUE); } //先测量用此画笔画字母的大小，用一个矩形把它包裹起来，这样方便计算字母的高度 Rect bounds = new Rect(); paint.getTextBounds(indexs[i], 0, indexs[i].length(), bounds); //计算画每个字母的起始坐标 float x = cellWidth / 2 - paint.measureText(indexs[i]) / 2; float y = cellHeight / 2 + bounds.height() / 2 + i * cellHeight; canvas.drawText(indexs[i], x, y, paint); } } private int lastIndex = -1; @Override public boolean onTouchEvent(MotionEvent event) { int x = (int) event.getX();// if (x >= 0 && x <= cellWidth) { //只对quickindexbar的触摸事件有效// return false;// } int y = (int) event.getY(); switch (event.getAction()) { case MotionEvent.ACTION_DOWN: case MotionEvent.ACTION_MOVE: if (isSameIndex(y / cellHeight)) break; //安全检查 if (y >= 0 && (y / cellHeight) < indexs.length) { String word = indexs[((int) (y / cellHeight))]; lastIndex = y / cellHeight; if (mIndexChangedListener != null) { mIndexChangedListener.indexChanged(word); } } break; case MotionEvent.ACTION_UP: lastIndex = -1; break; default: break; } //重新调用onDraw invalidate(); //自行处理触摸事件，不向上传递 return true; } /** * 当前的索引位置是否和上一个相等 */ private boolean isSameIndex(int currIndex) { return lastIndex == currIndex; } private IndexChangedListener mIndexChangedListener; public void setIndexChangedListener(IndexChangedListener indexChangedListener) { mIndexChangedListener = indexChangedListener; } public interface IndexChangedListener { void indexChanged(String word); }}
2，这个类是自定义索引条与本人项目的结合/////////////////////////下面的是结合的部分，其他是自己项目的内容

3，对应布局文件如下：
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" ><LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#fff" android:orientation="vertical"> <fragment android:id="@+id/title" android:layout_width="match_parent" android:layout_height="46dp" android:name="cn.sh.steel.fragment.TitleFragment"/> <LinearLayout android:id="@+id/query_wrap" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:background="@color/light_gray2" android:weightSum="10"> <ImageView android:layout_width="26dp" android:layout_height="26dp" android:src="@drawable/glass" android:layout_gravity="center_vertical" android:paddingLeft="10dp"/> <EditText android:id="@+id/keyword" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="姓名/手机" android:background="@drawable/searchbox" android:textSize="16sp" android:singleLine="true" android:imeOptions="actionDone" android:textColor="#333"/> </LinearLayout> <LinearLayout android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent"> <ListView android:id="@+id/cust_list" android:layout_height="match_parent" android:dividerHeight="6dp" android:divider="@color/light_gray2" android:layout_toRightOf="@+id/showLabel" android:layout_toEndOf="@+id/showLabel" android:layout_weight="18" android:layout_width="0dp" android:footerDividersEnabled="true"/> <cn.sh.steel.QuickIndexBar android:id="@+id/quickbar" android:layout_weight="1" android:layout_width="0dp" android:layout_height="match_parent" android:layout_alignParentRight="true" android:layout_alignParentEnd="true" android:background="@color/white" /> </LinearLayout></LinearLayout> <!--中间放大部分显示的文字--> <TextView android:id="@+id/showLabel" android:layout_width="120dp" android:layout_height="120dp" android:textColor="@color/radio_button_selected_color" android:visibility="gone" android:gravity="center" android:layout_centerInParent="true" android:textSize="50sp" android:background="@drawable/shap" android:padding="5dp" android:text="A" /></RelativeLayout>
4，下面这个类是汉字转拼音的类
