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;
		}

	}

这样大家可以随心所欲的编写自己喜欢的动画效果。
