ListView的A-Z字母排序 ListView的过滤搜索汉字转成拼音

前段时间因为换工作的缘故又恰巧碰到国庆节，所以有段时间自己没有更新博客了，过完国庆到新公司报道，感觉还不错，就是现在住的地方离新公司有点远，地铁20站，伤不起啊，我每天早上7点多就要起床，然后屁颠屁颠的去挤地铁上班，晚上下班还要挤地铁，先不说路程远，车费一天就要10几块，我的银子啊，有坐龙华线去上班的深圳程序员不？听说那条线上班高峰期很挤？我没在上班高峰期坐过那趟车，我在民治那边找了个房子，离华强北也不远，关键房租便宜，哈哈，乐开花了，下个礼拜就要搬过去啦

不扯了，回到主题，今天给大家带来ListView的A-Z字母排序和过滤搜索功能并且实现汉字转成拼音的功能，我们知道一般我们对联系人，城市列表等实现A-Z的排序，因为联系人和城市列表我们可以直接从数据库中获取他的汉字拼音，而对于一般的数据，我们怎么实现A-Z的排序，我们需要将汉字转换成拼音就行了，接下来就带大家实现一般数据的A-Z排序功能，首先先看下效果图

上面是一个带删除按钮的EditText，我们在输入框中输入可以自动过滤出我们想要的东西，当输入框中没有数据自动替换到原来的数据列表，然后下面一个ListView用来显示数据列表，右侧是一个字母索引表，当我们点击不同的字母,ListView会定位到该字母地方，了解了布局之后，我们先看下项目结构吧

我按照项目中类的顺序来一一介绍其功能

1.SortModel 一个实体类，里面一个是ListView的name,另一个就是显示的name拼音的首字母

[java] view plain copy

packagecom.example.sortlistview;
publicclassSortModel{
privateStringname;//显示的数据
privateStringsortLetters;//显示数据拼音的首字母
publicStringgetName(){
returnname;
}
publicvoidsetName(Stringname){
this.name=name;
}
publicStringgetSortLetters(){
returnsortLetters;
}
publicvoidsetSortLetters(StringsortLetters){
this.sortLetters=sortLetters;
}
}

2.SideBar类就是ListView右侧的字母索引View，我们需要使用setTextView(TextView mTextDialog)来设置用来显示当前按下的字母的TextView,以及使用setOnTouchingLetterChangedListener方法来设置回调接口，在回调方法onTouchingLetterChanged(String s)中来处理不同的操作

[java] view plain copy

packagecom.example.sortlistview;
importandroid.content.Context;
importandroid.graphics.Canvas;
importandroid.graphics.Color;
importandroid.graphics.Paint;
importandroid.graphics.Typeface;
importandroid.graphics.drawable.ColorDrawable;
importandroid.util.AttributeSet;
importandroid.view.MotionEvent;
importandroid.view.View;
importandroid.widget.TextView;
publicclassSideBarextendsView{
//触摸事件
privateOnTouchingLetterChangedListeneronTouchingLetterChangedListener;
//26个字母
publicstaticString[]b={"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","#"};
privateintchoose=-1;//选中
privatePaintpaint=newPaint();
privateTextViewmTextDialog;
/**
*为SideBar设置显示字母的TextView
*@parammTextDialog
*/
publicvoidsetTextView(TextViewmTextDialog){
this.mTextDialog=mTextDialog;
}
publicSideBar(Contextcontext,AttributeSetattrs,intdefStyle){
super(context,attrs,defStyle);
}
publicSideBar(Contextcontext,AttributeSetattrs){
super(context,attrs);
}
publicSideBar(Contextcontext){
super(context);
}
/**
*重写这个方法
*/
protectedvoidonDraw(Canvascanvas){
super.onDraw(canvas);
//获取焦点改变背景颜色.
intheight=getHeight();//获取对应高度
intwidth=getWidth();//获取对应宽度
intsingleHeight=height/b.length;//获取每一个字母的高度
for(inti=0;i<b.length;i++){
paint.setColor(Color.rgb(33,65,98));
//paint.setColor(Color.WHITE);
paint.setTypeface(Typeface.DEFAULT_BOLD);
paint.setAntiAlias(true);
paint.setTextSize(20);
//选中的状态
if(i==choose){
paint.setColor(Color.parseColor("#3399ff"));
paint.setFakeBoldText(true);
}
//x坐标等于中间-字符串宽度的一半.
floatxPos=width/2-paint.measureText(b[i])/2;
floatyPos=singleHeight*i+singleHeight;
canvas.drawText(b[i],xPos,yPos,paint);
paint.reset();//重置画笔
}
}
@Override
publicbooleandispatchTouchEvent(MotionEventevent){
finalintaction=event.getAction();
finalfloaty=event.getY();//点击y坐标
finalintoldChoose=choose;
finalOnTouchingLetterChangedListenerlistener=onTouchingLetterChangedListener;
finalintc=(int)(y/getHeight()*b.length);//点击y坐标所占总高度的比例*b数组的长度就等于点击b中的个数.
switch(action){
caseMotionEvent.ACTION_UP:
setBackgroundDrawable(newColorDrawable(0x00000000));
choose=-1;//
invalidate();
if(mTextDialog!=null){
mTextDialog.setVisibility(View.INVISIBLE);
}
break;
default:
setBackgroundResource(R.drawable.sidebar_background);
if(oldChoose!=c){
if(c>=0&&c<b.length){
if(listener!=null){
listener.onTouchingLetterChanged(b[c]);
}
if(mTextDialog!=null){
mTextDialog.setText(b[c]);
mTextDialog.setVisibility(View.VISIBLE);
}
choose=c;
invalidate();
}
}
break;
}
returntrue;
}
/**
*向外公开的方法
*
*@paramonTouchingLetterChangedListener
*/
publicvoidsetOnTouchingLetterChangedListener(
OnTouchingLetterChangedListeneronTouchingLetterChangedListener){
this.onTouchingLetterChangedListener=onTouchingLetterChangedListener;
}
/**

publicinterfaceOnTouchingLetterChangedListener{
publicvoidonTouchingLetterChanged(Strings);
}
}

3.CharacterParser这个类是将汉字转换成拼音的类，该拼音没有声调的，该类是单例类，其中定义了三个方法，在这个demo中用到的是getSelling(String chs)方法，将词组转换成拼音

[java] view plain copy

packagecom.example.sortlistview;
/**

*/
publicclassCharacterParser{
privatestaticint[]pyvalue=newint[]{-20319,-20317,-20304,-20295,-20292,-20283,-20265,-20257,-20242,-20230,-20051,-20036,-20032,

4.ClearEditText类是自定义的一个在右侧有删除图片的EditText，当然你也可以用Android原生的EditText，该类我之前有介绍，我这里就不贴上代码了Android 带清除功能的输入框控件ClearEditText,仿IOS的输入框

5.SortAdapter 数据的适配器类，该类需要实现SectionIndexer接口，该接口是用来控制ListView分组的，该接口有三个方法getSectionForPosition(int position)，getPositionForSection(int section)，getSections()，我们只需要自行实现前面两个方法

getSectionForPosition(int position)是根据ListView的position来获取该位置上面的name的首字母char的ascii值，例如：如果该position上面的name是阿妹，首字母就是A，那么此方法返回的就是'A'字母的ascii值，也就是65， 'B'是66，依次类推
getPositionForSection(int section)就是根据首字母的ascii值来获取在该ListView中第一次出现该首字母的位置，例如：从上面的效果图1中，如果section是66 ，也就是‘B’的ascii值，那么该方法返回的position就是2

然后就是getView()方法，首先我们根据ListView的position调用getSectionForPosition(int position)来获取该位置上面name的首字母的ascii值,然后根据这个ascii值调用getPositionForSection(int section)来获取第一次出现该首字母的position，如果ListView的position 等于根据这个ascii值调用getPositionForSection(int section)来获取第一次出现该首字母的position，则显示分类字母否则隐藏

6.MainActivity这里面的代码比较简单，我们对ClearEditText设置addTextChangedListener监听，当输入框内容发生变化根据里面的值过滤ListView，里面的值为空显示原来的列表，里面对列表数据进行排序用到PinyinComparator接口，该接口主要是用来比较对象的

//根据a-z进行排序
Collections.sort(filterDateList,pinyinComparator);
adapter.updateListView(filterDateList);
}
}

7.PinyinComparator接口用来对ListView中的数据根据A-Z进行排序，前面两个if判断主要是将不是以汉字开头的数据放在后面

[java] view plain copy

packagecom.example.sortlistview;
importjava.util.Comparator;
/**
*
*@authorxiaanming
*
*/
publicclassPinyinComparatorimplementsComparator<SortModel>{
publicintcompare(SortModelo1,SortModelo2){
//这里主要是用来对ListView里面的数据根据ABCDEFG...来排序
if(o2.getSortLetters().equals("#")){
return-1;
}elseif(o1.getSortLetters().equals("#")){
return1;
}else{
returno1.getSortLetters().compareTo(o2.getSortLetters());
}
}
}
