MainActivity如下:

package cc.testpointtoposition;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import android.os.Bundle;import android.view.MotionEvent;import android.view.View;import android.view.View.OnTouchListener;import android.widget.ListView;import android.widget.SimpleAdapter;import android.app.Activity;/** * Demo描述: * ListView中pointToPosition()方法使用示例. * 依据触摸点的坐标计算出点击的是ListView的哪个Item *  * 参考资料: * http://blog.csdn.net/guolin_blog/article/details/17357967 * Thank you very much */public class MainActivity extends Activity {    private ListView mListView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);init();listenListViewTouch();}private void init(){mListView=(ListView) findViewById(R.id.listView);        List<HashMap<String, Object>> list=new ArrayList<HashMap<String,Object>>();      HashMap<String, Object> hashMap=null;      for (int i = 0; i < 8; i++) {      hashMap=new HashMap<String, Object>();      hashMap.put("name", "小明"+i);          hashMap.put("phone", "135"+i);          hashMap.put("amount","500"+i);        list.add(hashMap);}      SimpleAdapter adapter=new SimpleAdapter(this, list, R.layout.listviewitem,       new String []{"name","phone","amount"}, new int[]{R.id.name,R.id.phone,R.id.amount});      mListView.setAdapter(adapter);}private void listenListViewTouch(){ mListView.setOnTouchListener(new OnTouchListener() {@Overridepublic boolean onTouch(View v, MotionEvent event) {int item=mListView.pointToPosition((int) event.getX(), (int) event.getY());System.out.println("---> 现在点击了ListView中第"+(item+1)+"个Item");return true;}});}}

main.xml如下:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <TextView        android:id="@+id/textView"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:gravity="center_horizontal"        android:text="测试ListView的pointToPosition()方法" />    <ListView        android:id="@+id/listView"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:layout_below="@id/textView" /></RelativeLayout>

listviewitem如下:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="50dip"    android:gravity="center"    android:orientation="horizontal" >    <TextView        android:id="@+id/name"        android:layout_width="100dip"        android:layout_height="wrap_content" />    <TextView        android:id="@+id/phone"        android:layout_width="150dip"        android:layout_height="wrap_content" />    <TextView        android:id="@+id/amount"        android:layout_width="fill_parent"        android:layout_height="wrap_content" /></LinearLayout>
