Android动画

这两天一直看在Sundy的动画教程，看完总结如下。

动画分类

   1.Peoperty Animation

      这个动画是Android3.0之后推出的目前用处不大。

   2.View Animation

       这类动画也叫tween animation 主要分为 渐变动画(AlphaAnimation)旋转动画(RotateAnimation)

缩放动画(ScaleAnimation)位移动画(TranslateAnimation)

 3.Drawable Animation

      这类动画也叫帧动画 FrameAnimation

Interpolator

    An interpolator defines the rate of change of an animation. This allows the basic animation effects (alpha, scale, translate, rotate) to be  accelerated, decelerated, repeated

直接上代码

public class TestAnimaionActivity extends Activity {
	private ImageView imageView;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        imageView=(ImageView)findViewById(R.id.imageView1);
        Button btnAlpha=(Button)findViewById(R.id.Alpha);
        Button btnRotate=(Button)findViewById(R.id.Rotate);
        Button btnScale=(Button)findViewById(R.id.Scale);
        Button btnTranslate=(Button)findViewById(R.id.Translate);
        Button btnAnimationSet=(Button)findViewById(R.id.animationSet);
        btnAlpha.setOnClickListener(new AnimationClickListener(AnimationType.Alpha));
        btnRotate.setOnClickListener(new AnimationClickListener(AnimationType.Rotate));
        btnScale.setOnClickListener(new AnimationClickListener(AnimationType.Scale));
        btnTranslate.setOnClickListener(new AnimationClickListener(AnimationType.Translate));
        btnAnimationSet.setOnClickListener(new AnimationClickListener(AnimationType.Complex));
    }
    
    enum AnimationType{
    	Alpha,
    	Rotate,
    	Scale,
    	Translate,
    	Complex;
    }
    
    private class AnimationClickListener implements View.OnClickListener{

    	private AnimationType animationType;
    	
		public AnimationClickListener(AnimationType animationType) {
			super();
			this.animationType = animationType;
		}

		@Override
		public void onClick(View v) {
			switch (animationType) {
			case Alpha:
				AlphaAnimation alphaAnimation=(AlphaAnimation) AnimationUtils.loadAnimation(TestAnimaionActivity.this, R.anim.alphaanim);
				alphaAnimation.setRepeatCount(5);
				alphaAnimation.setRepeatMode(Animation.REVERSE);
				imageView.startAnimation(alphaAnimation);
				break;
			case Rotate:
				RotateAnimation rotateAnimation=new RotateAnimation(0, 360,  Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,0.5f);
			    rotateAnimation.setDuration(3000);
			    rotateAnimation.setRepeatCount(3);

				break;
			case Scale:

				scaleAnimation.setZAdjustment(Animation.ZORDER_NORMAL);
				imageView.startAnimation(scaleAnimation);
				break;
			case Translate:
				TranslateAnimation translateAnimation=new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 2f, Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 2f);
				translateAnimation.setInterpolator(new AccelerateDecelerateInterpolator());
				translateAnimation.setDuration(3000);
				imageView.startAnimation(translateAnimation);
				break;
			case Complex:
			    AnimationSet animationSet=new AnimationSet(false);
				AlphaAnimation alphaAnimation2=new AlphaAnimation(1.0f, 0.1f);
				alphaAnimation2.setDuration(3000);
				TranslateAnimation translateAnimation2=new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 2f, Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 2f);
				translateAnimation2.setDuration(3000);
				RotateAnimation rotateAnimation2=new RotateAnimation(0, 360,  Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,0.5f);
			    rotateAnimation2.setDuration(3000);
			    animationSet.addAnimation(alphaAnimation2);
			    animationSet.addAnimation(translateAnimation2);
			    animationSet.addAnimation(rotateAnimation2);
				imageView.startAnimation(animationSet);
				break;

			default:
				break;
