fry.Activity01

 1 package fry;
 2 
 3 import com.example.ListView.R;
 4 
 5 import android.app.Activity;
 6 import android.os.Bundle;
 7 import android.view.View;
 8 import android.widget.AdapterView;
 9 import android.widget.AdapterView.OnItemClickListener;
10 import android.widget.ArrayAdapter;
11 import android.widget.ListView;
12 import android.widget.Toast;
13 
14 public class Activity01 extends Activity implements OnItemClickListener{
15     private ListView listView;
16     @Override
17     protected void onCreate(Bundle savedInstanceState) {
18         // TODO Auto-generated method stub
19         super.onCreate(savedInstanceState);
20         setContentView(R.layout.activity01);
21         listView=(ListView) findViewById(R.id.listView);
22         ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1, getData());
23         listView.setAdapter(adapter);
24         listView.setOnItemClickListener(this);
25     }
26     @Override
27     public void onItemClick(AdapterView<?> parent, View view, int position,
28             long id) {
29         // TODO Auto-generated method stub
30         String string=(String) parent.getItemAtPosition(position);
31         
32         Toast.makeText(this, string, Toast.LENGTH_SHORT).show();
33     }
34     
35     private String[] getData(){
36         return new String[]{"韓寒","蔡靜","盧本偉","五五開","戰狼2","朝陽兄","虹橋一姐","犀利哥","王寶慶",
37                 "系大大","搞踹踹","張三","李四","王五"};
38     }
