下面就是java代码了

public class MainActivity extends Activity {

private String[] name = {"张三","李四","王五","刘六","张三","李四","王五","刘六"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView) findViewById(R.id.listview);
//创建一个ArrayAdapter
listView.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, name));
//listView注册一个元素点击事件监听器
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
//当某个元素被点击时调用该方法
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
Toast.makeText(MainActivity.this,name[arg2] ,
Toast.LENGTH_LONG).show();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
