在Android中listview是最常用的控制項之一,但是有時候我們會覺得千篇一律的listview看起來過於單調,於是就產生了listView動畫,listview載入了動畫會讓使用者體驗更好,本期就分享一些listview動畫以及實現方法,
相信大家都熟悉Android的Tween動畫,前四種動畫就是Translate,Alpha,Rotate,Scale,最後一種Rotate3d則是用了一個3D旋轉動畫工具類Rotate3dAnimation,這個類的建構函式中接收一些3D旋轉時所需用到的參數,比如旋轉開始和結束的角度,旋轉的中心點等。
LayoutAnimationController可以控制一組控制項按照規定顯示,ListView中的mListView.setLayoutAnimation相信大家都知道是用來幹什麼的了,接下來上代碼
[java] view plaincopy
- private Button button, button2, button3, button4, button5;
- private ListView mListView;
- private Animation animation;
- private LayoutAnimationController controller;
- private String[] arry = { "一", "二", "三", "四", "五", "六" };
- private ArrayAdapter<String> adapter;
-
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.activity_main);
- initView();
- adapter = new ArrayAdapter<String>(this,
- android.R.layout.simple_list_item_1, arry);
- mListView.setAdapter(adapter);

- }

- @Override
- public void onClick(View arg0) {
- // LayoutAnimationController.ORDER_NORMAL; 順序顯示
- // LayoutAnimationController.ORDER_REVERSE;反顯示
- // LayoutAnimationController.ORDER_RANDOM; 隨機顯示
- switch (arg0.getId()) {
- case R.id.btn_tran:
- animation = new TranslateAnimation(-50f, 0f, 0f, 0f);
- animation.setDuration(500);
- //1f為延時
- controller = new LayoutAnimationController(animation, 1f);
- controller.setOrder(LayoutAnimationController.ORDER_NORMAL);
- mListView.setLayoutAnimation(controller);
- adapter.notifyDataSetInvalidated();
- break;
