Android ListView动画实现方法
在Android中listview是最常用的控件之一,但是有时候我们会觉得千篇一律的listview看起来过于单调,于是就产生了listView动画,listview加载了动画会让用户体验更好,本期就分享一些listview动画以及实现方法,效果图
相信大家都熟悉Android的Tween动画,前四种动画就是Translate,Alpha,Rotate,Scale,最后一种Rotate3d则是用了一个3D旋转动画工具类Rotate3dAnimation,这个类的构造函数中接收一些3D旋转时所需用到的参数,比如旋转开始和结束的角度,旋转的中心点等。
LayoutAnimationController可以控制一组控件按照规定显示,ListView中的mListView.setLayoutAnimation相信大家都知道是用来干什么的了,接下来上代码
- 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);
- }
- private void initView() {
- // TODO Auto-generated method stub
- mListView = (ListView) findViewById(R.id.list);
- button = (Button) findViewById(R.id.btn_tran);
- button.setOnClickListener(this);
- button2 = (Button) findViewById(R.id.btn_alpha);
- button2.setOnClickListener(this);
- button3 = (Button) findViewById(R.id.btn_rotate);
- button3.setOnClickListener(this);
- button4 = (Button) findViewById(R.id.btn_scale);
- button4.setOnClickListener(this);
- button5 = (Button) findViewById(R.id.rotate3d);
- button5.setOnClickListener(this);
- }
- @Override
- public void onClick(View arg0) {
- // LayoutAnimationController.ORDER_NORMAL; 顺序显示
- // LayoutAnimationController.ORDER_REVERSE;反显示
- // LayoutAnimationController.ORDER_RANDOM; 随机显示
- switch (arg0.getId()) {
- case R.id.btn_tran:
- animation = new TranslateAnimation(-50f, 0f, 0f, 0f);
- animation.setDuration(500);
- //1f为延时
- controller = new LayoutAnimationController(animation, 1f);
- controller.setOrder(LayoutAnimationController.ORDER_NORMAL);
- mListView.setLayoutAnimation(controller);
- adapter.notifyDataSetInvalidated();
- break;
- case R.id.btn_alpha:
- animation = new AlphaAnimation(0f, 1f);
- animation.setDuration(500);
- controller = new LayoutAnimationController(animation, 1f);
- controller.setOrder(LayoutAnimationController.ORDER_NORMAL);
- mListView.setLayoutAnimation(controller);
- adapter.notifyDataSetInvalidated();
- break;
- case R.id.btn_rotate:
- animation = new RotateAnimation(0f, 360f);
- animation.setDuration(500);
- controller = new LayoutAnimationController(animation, 1f);
- controller.setOrder(LayoutAnimationController.ORDER_NORMAL);
- mListView.setLayoutAnimation(controller);
- adapter.notifyDataSetInvalidated();
- break;
- case R.id.btn_scale:
- animation = new ScaleAnimation(0.1f, 1.0f, 0.1f, 1.0f);
- animation.setDuration(500);
- controller = new LayoutAnimationController(animation, 1f);
- controller.setOrder(LayoutAnimationController.ORDER_NORMAL);
- mListView.setLayoutAnimation(controller);
- adapter.notifyDataSetInvalidated();
- break;
- case R.id.rotate3d:
- animation = new Rotate3dAnimation(0, 360, 200, 200, 0, true);
- animation.setDuration(1000);
- controller = new LayoutAnimationController(animation, 0.1f);
- controller.setOrder(LayoutAnimationController.ORDER_NORMAL);
- mListView.setLayoutAnimation(controller);
- adapter.notifyDataSetInvalidated();
- break;
- default:
- break;
- }
- }
