在Android中listview是最经常使用的控件之中的一个,可是有时候我们会认为千篇一律的listview看起来过于单调,于是就产生了listView动画,listview载入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旋转时所需用到的參数。比方旋转開始和结束的角度,旋转的中心点等。
LayoutAnimationController能够控制一组控件依照规定显示。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 ArrayAdapteradapter; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); adapter = new ArrayAdapter (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; } }
这样大家能够随心所欲的编写自己喜欢的动画效果
