如何避免onItemClick和onCreateContextMenu被调用

Question

我的活动使用ListView。我想在用户长时间点击项目时选择X，而在正常点击时选择Y.我的onCreate（）包含的代码，如：

mListView = (ListView) findViewById(android.R.id.list); 
registerForContextMenu(mListView); 
mListView.setOnItemClickListener(this); 

我看到的行为是，当一个项目的用户长期的水龙头，都onCreateContextMenu（）和onItemClick（）被调用。

我该如何避免这种情况？

试试这个，我已经测试它和上下文菜单被称为只在长按和唯一的onclick点击列表视图项事件发生

package com.example.listview; 

import android.app.ListActivity; 
import android.graphics.Color; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.ContextMenu; 
import android.view.ContextMenu.ContextMenuInfo; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 
import android.widget.TextView; 
import android.widget.Toast; 
import android.widget.AdapterView.OnItemClickListener; 

public class ListViewExampleActivity extends ListActivity { 

static final String[] STATES = new String[] { "Haryana", "Punjab", "Rajasthan", 
     "Maharashtra", "Madhya Pradesh", "Kerala", "Jammu","Bihar","Karnataka" , "TamilNadu", 
       "Uttar Pradesh" ,"Gujrat"}; 
View listColor; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setListAdapter(new ArrayAdapter<String>(this, R.layout.main,STATES)); 

    ListView listView = getListView(); 
    listView.setTextFilterEnabled(true); 

    listView.setBackgroundColor(getTitleColor()); 
    registerForContextMenu(listView); 
    listView.setOnItemClickListener(new OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View view, 
       int position, long id) { 
      if(listColor!=null){ 
       listColor.setBackgroundColor(Color.BLACK); 
       listColor=view; 
      }else{ 

       listColor=view; 

      } 
      Log.i("called", "item click"); 
      listColor.setBackgroundColor(Color.BLUE); 
      //on click of any item the item name will be shown in toast 
      Toast.makeText(getApplicationContext(), 
      ((TextView) view).getText(), Toast.LENGTH_SHORT).show(); 
     } 
    }); 

} 
@Override 
public void onCreateContextMenu(ContextMenu menu, View v, 
    ContextMenuInfo menuInfo) { 
    Log.i("called", "Context menu"); 
    Toast.makeText(getApplicationContext(), 
      "Context menu", Toast.LENGTH_SHORT).show(); 
} 
}
