ScrollView与ListView的事件冲突

布局文件

当ListView嵌套在ScrollView中时，会发生冲突，导致ListView控件的拉动效果消失‘

解决办法：

重写ListView的onTouchEvent(),并在返回前调用getParent().requestDisallowInterceptTouchEvent(true)  表示。不允许父层拦截或干扰本控件

Demo

 package com.xqx.fight;

 import android.app.Activity;
 import android.os.Bundle;
 import android.view.Menu;
 import android.view.MotionEvent;
 import android.view.View;
 import android.view.View.OnTouchListener;
 import android.widget.ArrayAdapter;
 import android.widget.ListView;

 public class MainActivity extends Activity {

     private ListView listView;
     private ArrayAdapter<String > adapter;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);

         listView = (ListView) findViewById(R.id.listView);
         adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1);
         for(int i=;i<;i++)
         {
             adapter.add("列表项:"+i);
         }
         listView.setAdapter(adapter);

         listView.setOnTouchListener(new OnTouchListener() {

             @Override
             public boolean onTouch(View v, MotionEvent event) {
                 //getParent().requestDisallowInterceptTouchEvent(true)  不允许父层拦截或干扰本控件
                 listView.getParent().requestDisallowInterceptTouchEvent(true);
                 return false;
             }
         });
     }

 }
