Android ListView - 如何应对物品点击？

Question

比方说，我有一个ListView与一些项目。我想这样做，当用户点击一个项目，应用程序弹出一个Toast包含项目的名称。例如，当用户点击“苹果”时，他们会看到敬酒：“你吃苹果。”我该怎么做？

Answer 1

您可以设置项目点击监听器的列表视图即

listvw=(ListView)findViewById(R.id.listviewid); 

listvw.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) { 

      Toast.makeText(ActivityName.this, "Text message", Toast.LENGTH_SHORT).show(); 

     } 
    }); 

Answer 2

标准使用方式.setOnItemClickListener()。

Answer 3

使用这样的

ActivityListView的.java

package com.sunil; 

    import android.app.ListActivity; 
    import android.os.Bundle; 
    import android.view.View; 
    import android.widget.ArrayAdapter; 
    import android.widget.ListView; 
    import android.widget.Toast; 

    public class ActivityListView extends ListActivity { 

    public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    // Create an array of Strings, that will be put to our ListActivity 
    String[] namesArray = new String[] { "Linux", "Windows7", "Eclipse", 
     "Suse", "Ubuntu", "Solaris", "Android", "iPhone" }; 

    /* Create an ArrayAdapter, that will actually make the Strings above 
     appear in the ListView */ 

    this.setListAdapter(new ArrayAdapter<String>(this, 
     android.R.layout.simple_list_item_1, namesArray)); 
    } 
     @Override 
     protected void onListItemClick(ListView l, View v, 
     int position, long id) { 
    super.onListItemClick(l, v, position, id); 

    // Get the item that was clicked 

    Object o = this.getListAdapter().getItem(position); 
    String keyword = o.toString(); 
    Toast.makeText(this, "You selected: " + keyword, 
     Toast.LENGTH_SHORT).show(); 
    } 
    } 

main.xml中

<?xml version="1.0" encoding="utf-8"?> 

    <LinearLayout 

    xmlns:android="http://schemas.android.com/apk/res/android" 

    android:orientation="vertical" 

    android:layout_width="fill_parent" 

    android:layout_height="fill_parent"> 

    <TextView 

     android:layout_width="fill_parent" 

     android:layout_height="wrap_content" 

     android:text="@string/hello" /> 

    </LinearLayout> 

Answer 4

试试这个代码 listview =（ListView）findViewById（R.id.listid）;

listview.setOnItemClickListener(new OnItemClickListener() { 

    @Override 
    public void onItemClick(AdapterView<?> arg0, View arg1, int pos,long arg3) { 

     // to set your list item or name 

     //here list is your list that you set in your adapter  
      list.get(pos); 

    } 
});
