1.代码

@Overridepublic void onClick(View v) {// TODO Auto-generated method stubswitch(v.getId()){case R.id.btnAlphaAnimationByCode:{AlphaAnimation aa = new AlphaAnimation(0,1);aa.setDuration(1000);v.startAnimation(aa);}break;case R.id.btnAlphaAnimationByXml:{v.startAnimation(AnimationUtils.loadAnimation(getActivity(), R.anim.alpha_animation));}break;case R.id.btnRotationAnimationByCode:{RotateAnimation ra ;//ra = new RotateAnimation(0,360,100,100);////ra = new RotateAnimation(0,360,100,100);//从0-360度,第三,四个参数是旋转中心点的x,y坐标相对与本视图左上角.ra = new RotateAnimation(0,360,Animation.RELATIVE_TO_SELF,0.5f,Animation.RELATIVE_TO_SELF,0.5f);//相对于自身的中心点旋转.ra.setDuration(1000);v.startAnimation(ra);}break;case R.id.btnRotationAnimationByXml:{v.startAnimation(AnimationUtils.loadAnimation(getActivity(), R.anim.rotation_animation));}break;case R.id.btnTranslateAnimationView:{getFragmentManager().beginTransaction()                  .addToBackStack("T")                  .replace(R.id.container, new TranslationFragment())                  .commit();}break;case R.id.btnScaleAnimationByCode:{ScaleAnimation sa ;//float fromX, float toX, float fromY, float toY 默认锚点是左上 //sa = new ScaleAnimation(0,1,0,1);//后两个参数是锚点坐标,是从自身的左上开始的absolute绝对坐标值.//sa = new ScaleAnimation(0,1,0,1,200,200);sa = new ScaleAnimation(0,1,0,1,Animation.RELATIVE_TO_SELF,0.5f,Animation.RELATIVE_TO_SELF,0.5f);sa.setDuration(1000);v.startAnimation(sa);}break;case R.id.btnScaleAnimationByXml:{v.startAnimation(AnimationUtils.loadAnimation(getActivity(), R.anim.scale_animation));}break;case R.id.btnTranslateAndAlphaByCode:{AnimationSet as = new AnimationSet(true);as.setDuration(1000);AlphaAnimation aa = new AlphaAnimation(0,1);as.addAnimation(aa);TranslateAnimation ta = new TranslateAnimation(100,0,100,0);as.addAnimation(ta);v.startAnimation(as);}break;case R.id.btnTranslateAndAlphaByXml:Animation a = AnimationUtils.loadAnimation(getActivity(), R.anim.set_animation);a.setAnimationListener(this);v.startAnimation(a);break;case R.id.btnCustomAnimation:{getFragmentManager().beginTransaction()                  .addToBackStack("C")                  .replace(R.id.container, new CustomAnimationFragment())                .commit();}break;}}

2.xml配置动画

每个xm一个独立文件 ,在res/anim 下.

<?xml version="1.0" encoding="utf-8"?><alpha     xmlns:android="http://schemas.android.com/apk/res/android"    android:fromAlpha="0"    android:toAlpha="1"    android:duration="1000"     ></alpha>

<rotate xmlns:android="http://schemas.android.com/apk/res/android"android:fromDegrees="0"android:toDegrees="360"android:duration="1000"android:pivotX="50%"android:pivotY="50%"    ></rotate>

<?xml version="1.0" encoding="utf-8"?><scale android:fromXScale="0"android:toXScale="1"android:fromYScale="0"android:toYScale="1"android:duration="1000"android:pivotX="50%"android:pivotY="50%"    xmlns:android="http://schemas.android.com/apk/res/android"></scale>

<?xml version="1.0" encoding="utf-8"?><set android:duration="1000"     android:shareInterpolator="true"    xmlns:android="http://schemas.android.com/apk/res/android">    <alpha android:fromAlpha="0" android:toAlpha="1"></alpha><translate android:fromXDelta="0" android:toXDelta="100"    android:fromYDelta="0" android:toYDelta="100"></translate></set>

<?xml version="1.0" encoding="utf-8"?><translate     xmlns:android="http://schemas.android.com/apk/res/android"    android:fromXDelta="0"    android:toXDelta="0"    android:fromYDelta="0"    android:toYDelta="100"    android:duration="1000"     ></translate>
