Android实现ListView的A-Z字母排序和过滤搜索功能,实现汉字转成拼音

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

package com.example.sortlistview;public class SortModel {	private String name;   //显示的数据	private String sortLetters;  //显示数据拼音的首字母		public String getName() {		return name;	}	public void setName(String name) {		this.name = name;	}	public String getSortLetters() {		return sortLetters;	}	public void setSortLetters(String sortLetters) {		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

package com.example.sortlistview;import android.content.Context;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.graphics.Typeface;import android.graphics.drawable.ColorDrawable;import android.util.AttributeSet;import android.view.MotionEvent;import android.view.View;import android.widget.TextView;public class SideBar extends View {	// 触摸事件	private OnTouchingLetterChangedListener onTouchingLetterChangedListener;	// 26个字母	public static String[] 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", "#" };	private int choose = -1;// 选中	private Paint paint = new Paint();	private TextView mTextDialog;	/**	 * 为SideBar设置显示字母的TextView	 * @param mTextDialog	 */	public void setTextView(TextView mTextDialog) {		this.mTextDialog = mTextDialog;	}	public SideBar(Context context, AttributeSet attrs, int defStyle) {		super(context, attrs, defStyle);	}	public SideBar(Context context, AttributeSet attrs) {		super(context, attrs);	}	public SideBar(Context context) {		super(context);	}	/**	 * 重写这个方法	 */	protected void onDraw(Canvas canvas) {		super.onDraw(canvas);		// 获取焦点改变背景颜色.		int height = getHeight();// 获取对应高度		int width = getWidth(); // 获取对应宽度		int singleHeight = height / b.length;// 获取每一个字母的高度		for (int i = 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.			float xPos = width / 2 - paint.measureText(b[i]) / 2;			float yPos = singleHeight * i + singleHeight;			canvas.drawText(b[i], xPos, yPos, paint);			paint.reset();// 重置画笔		}	}	@Override	public boolean dispatchTouchEvent(MotionEvent event) {		final int action = event.getAction();		final float y = event.getY();// 点击y坐标		final int oldChoose = choose;		final OnTouchingLetterChangedListener listener = onTouchingLetterChangedListener;		final int c = (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) {		case MotionEvent.ACTION_UP:			setBackgroundDrawable(new ColorDrawable(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;		}		return true;	}	/**	 * 向外公开的方法	 * 	 * @param onTouchingLetterChangedListener	 */	public void setOnTouchingLetterChangedListener(			OnTouchingLetterChangedListener onTouchingLetterChangedListener) {		this.onTouchingLetterChangedListener = onTouchingLetterChangedListener;	}	/**	 * 接口	 * 	 * @author coder	 * 	 */	public interface OnTouchingLetterChangedListener {		public void onTouchingLetterChanged(String s);	}}

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

package com.example.sortlistview;/** * Java汉字转换为拼音 *  */public class CharacterParser {	private static int[] pyvalue = new int[] {-20319, -20317, -20304, -20295, -20292, -20283, -20265, -20257, -20242, -20230, -20051, -20036, -20032,			-20026, -20002, -19990, -19986, -19982, -19976, -19805, -19784, -19775, -19774, -19763, -19756, -19751, -19746, -19741, -19739, -19728,			-19725, -19715, -19540, -19531, -19525, -19515, -19500, -19484, -19479, -19467, -19289, -19288, -19281, -19275, -19270, -19263, -19261,			-19249, -19243, -19242, -19238, -19235, -19227, -19224, -19218, -19212, -19038, -19023, -19018, -19006, -19003, -18996, -18977, -18961,			-18952, -18783, -18774, -18773, -18763, -18756, -18741, -18735, -18731, -18722, -18710, -18697, -18696, -18526, -18518, -18501, -18490,			-18478, -18463, -18448, -18447, -18446, -18239, -18237, -18231, -18220, -18211, -18201, -18184, -18183, -18181, -18012, -17997, -17988,			-17970, -17964, -17961, -17950, -17947, -17931,

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65 ,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

package com.example.sortlistview;import java.util.ArrayList;import java.util.Collections;import java.util.List;import android.app.Activity;import android.os.Bundle;import android.text.Editable;import android.text.TextUtils;import android.text.TextWatcher;import android.view.View;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.ListView;import android.widget.TextView;import android.widget.Toast;import com.example.sortlistview.SideBar.OnTouchingLetterChangedListener;public class MainActivity extends Activity {	private ListView sortListView;	private SideBar sideBar;	/**	 * 显示字母的TextView	 */	private TextView dialog;	private SortAdapter adapter;	private ClearEditText mClearEditText;		/**	 * 汉字转换成拼音的类	 */	private CharacterParser characterParser;	private List<SortModel> SourceDateList;		/**	 * 根据拼音来排列ListView里面的数据类	 */	private PinyinComparator pinyinComparator;	@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);		initViews();	}	private void initViews() {		//实例化汉字转拼音类		characterParser = CharacterParser.getInstance();				pinyinComparator = new PinyinComparator();				sideBar = (SideBar) findViewById(R.id.sidrbar);		dialog = (TextView) findViewById(R.id.dialog);		sideBar.setTextView(dialog);				//设置右侧触摸监听		sideBar.setOnTouchingLetterChangedListener(new OnTouchingLetterChangedListener() {						@Override			public void onTouchingLetterChanged(String s) {				//该字母首次出现的位置				int position = adapter.getPositionForSection(s.charAt(0));				if(position != -1){					sortListView.setSelection(position);				}							}		});				sortListView = (ListView) findViewById(R.id.country_lvcountry);		sortListView.setOnItemClickListener(new OnItemClickListener() {			@Override			public void onItemClick(AdapterView<?> parent, View view,					int position, long id) {				//这里要利用adapter.getItem(position)来获取当前position所对应的对象				Toast.makeText(getApplication(), ((SortModel)adapter.getItem(position)).getName(), Toast.LENGTH_SHORT).show();			}		});				SourceDateList = filledData(getResources().getStringArray(R.array.date));				// 根据a-z进行排序源数据		Collections.sort(SourceDateList, pinyinComparator);		adapter = new SortAdapter(this, SourceDateList);		sortListView.setAdapter(adapter);						mClearEditText = (ClearEditText) findViewById(R.id.filter_edit);				//根据输入框输入值的改变来过滤搜索		mClearEditText.addTextChangedListener(new TextWatcher() {						@Override			public void onTextChanged(CharSequence s, int start, int before, int count) {				//当输入框里面的值为空,更新为原来的列表,否则为过滤数据列表				filterData(s.toString());			}						@Override			public void beforeTextChanged(CharSequence s, int start, int count,					int after) {							}						@Override			public void afterTextChanged(Editable s) {			}		});	}	/**	 * 为ListView填充数据	 * @param date	 * @return	 */	private List<SortModel> filledData(String [] date){		List<SortModel> mSortList = new ArrayList<SortModel>();				for(int i=0; i<date.length; i++){			SortModel sortModel = new SortModel();			sortModel.setName(date[i]);			//汉字转换成拼音			String pinyin = characterParser.getSelling(date[i]);			String sortString = pinyin.substring(0, 1).toUpperCase();						// 正则表达式,判断首字母是否是英文字母			if(sortString.matches("[A-Z]")){				sortModel.setSortLetters(sortString.toUpperCase());			}else{				sortModel.setSortLetters("#");			}						mSortList.add(sortModel);		}		return mSortList;			}		/**	 * 根据输入框中的值来过滤数据并更新ListView	 * @param filterStr	 */	private void filterData(String filterStr) {		List<SortModel> filterDateList = new ArrayList<SortModel>();		if (TextUtils.isEmpty(filterStr)) {			filterDateList = SourceDateList;		} else {			filterDateList.clear();			for (SortModel sortModel : SourceDateList) {				String name = sortModel.getName();				if (name.toUpperCase().indexOf(						filterStr.toString().toUpperCase()) != -1						|| characterParser.getSelling(name).toUpperCase()								.startsWith(filterStr.toString().toUpperCase())) {					filterDateList.add(sortModel);				}			}		}				// 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

package com.example.sortlistview;import java.util.Comparator;/** *  * @author xiaanming * */public class PinyinComparator implements Comparator<SortModel> {	public int compare(SortModel o1, SortModel o2) {		//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;		} else if (o1.getSortLetters().equals("#")) {			return 1;		} else {			return o1.getSortLetters().compareTo(o2.getSortLetters());		}	}}


这样我们以后使用A-Z排序就没要局限性了,想加这个效果随时都行,其他的布局和图片之类的文件就不贴出来了,如果大家有兴趣的自行去下载代码吧,如果大家有什么疑问,请在下面留言,我会为大家解答的!
