依然与前面是类似的效果：

但是代码要简单很多，也无需xml文件的帮助,上面按钮也是可以触发的：

public class EagleZip extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

String[] tKeyStr=new String[]{"压缩","解压","返回"};
ListView tListView=new ListView(this);

ArrayAdapter tAdapter = new ArrayAdapter
(this,android.R.layout.simple_list_item_1, tKeyStr);
tListView.setAdapter(tAdapter);
setContentView(tListView);
}
}
