爲listview，gridview添加布局動畫效果（通過資源文件方式）

public class MainActivity extends ListActivity {
private ArrayAdapter<String> adapter;
// private LayoutAnimationController lac;
// private ScaleAnimation sa;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, new String[]{"Hello","World","jikexueyuan"});
        
        setListAdapter(adapter);
        
        
//        sa = new ScaleAnimation(0, 1, 0, 1);
//        sa.setDuration(1000);
//        lac = new LayoutAnimationController(sa, 0.5f);
//        
//        getListView().setLayoutAnimation(lac);
    }

}
