android ListView根据字母排序和定位----支持混合排序

先看看图片效果，我的是来源于网上资料的改进，希望帮助对这方面有需要的的朋友

直接上图上代码，就不解释了，最底部有代码下载链接，想要的童鞋就去下吧

实现的功能：混合字符串处理  中英文排序   右侧悬浮栏   顶部名称提示栏   滚动悬浮提示

一 右侧字母表工具

import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;/*** 右侧字母表，快速定位** @author zuo* @email 782287169@qq.com*/
public class QuickLocationRightTool extends View
{private String[] b = null;public void setB(String[] b){this.b = b;}OnTouchingLetterChangedListener onTouchingLetterChangedListener;int choose = -1;Paint paint = new Paint();boolean showBkg = false;public QuickLocationRightTool(Context context, AttributeSet attrs, int defStyle){super(context, attrs, defStyle);}public QuickLocationRightTool(Context context, AttributeSet attrs){super(context, attrs);}public QuickLocationRightTool(Context context){super(context);}@Overrideprotected void onDraw(Canvas canvas){super.onDraw(canvas);if (showBkg) {canvas.drawColor(Color.parseColor("#10000000"));}int height = getHeight();int width = getWidth();int singleHeight = height / b.length;for (int i = 0; i < b.length; i++) {paint.setColor(Color.BLACK);paint.setTypeface(Typeface.DEFAULT_BOLD);paint.setAntiAlias(true);if (i == choose) {paint.setColor(Color.parseColor("#3399ff"));paint.setFakeBoldText(true);}float xPos = width / 2 - paint.measureText(b[i]) / 2;float yPos = singleHeight * i + singleHeight;canvas.drawText(b[i], xPos, yPos, paint);paint.reset();}}@Overridepublic boolean dispatchTouchEvent(MotionEvent event){final int action = event.getAction();final float y = event.getY();final int oldChoose = choose;final OnTouchingLetterChangedListener listener = onTouchingLetterChangedListener;final int c = (int) (y / getHeight() * b.length);    //字母位置switch (action) {case MotionEvent.ACTION_DOWN:showBkg = true;if (oldChoose != c && listener != null) {if (c > 0 && c <= b.length) { //如果第一个字母是#，无效点击的话，条件变为c>0listener.onTouchingLetterChanged(b[c]);choose = c;                  //处理重复invalidate();}}break;case MotionEvent.ACTION_MOVE:if (oldChoose != c && listener != null) {if (c > 0 && c <= b.length) {  //如果第一个字母是#，无效点击的话，条件变为c>0listener.onTouchingLetterChanged(b[c]);choose = c;invalidate();}}break;case MotionEvent.ACTION_UP:showBkg = false;choose = -1;invalidate();break;}return true;}@Overridepublic boolean onTouchEvent(MotionEvent event){return super.onTouchEvent(event);}public void setOnTouchingLetterChangedListener(OnTouchingLetterChangedListener onTouchingLetterChangedListener){this.onTouchingLetterChangedListener = onTouchingLetterChangedListener;}public interface OnTouchingLetterChangedListener{public void onTouchingLetterChanged(String s);}}
