嗨
我需要为列表视图执行onListItemClick事件.我做了以下但没有奏效.我粘贴我的代码和logcat.请帮我.错误是：(
java.lang.RuntimeException：您的内容必须有一个ListView,其id属性为’android.R.id.list’)
public class MyListView extends ListActivity {
// @Override
ListView list1;
private String array[] = { "Iphone", "Tutorials", "Gallery", "Android","item 1", "item 2", "item3", "item 4" };
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
list1 = (ListView) findViewById(R.id.ListView01);
list1.setAdapter(new ArrayAdapter(this,android.R.layout.simple_list_item_1, array));
}
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
Object o = this.getListAdapter().getItem(position);
String pen = o.toString();
Toast.makeText(this, "You have chosen the pen: " + " " + pen, Toast.LENGTH_LONG).show();
}
}
