Animation的小例子

1.在res文件夹中新建一个动画文件：例如  splash_anim.xml  

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <alpha 
        android:fromAlpha="0"
        android:toAlpha="1"
        android:duration="2000"
        />
</set>

2.启动动画：

private void initAnim() {
Animation anim = AnimationUtils.loadAnimation(this, R.anim.splash_anim);
animContainer.startAnimation(anim);
// new Handler().postDelayed(new Runnable() {
//
// @Override
// public void run() {
// Intent intent = new Intent(SplashActivity.this,MainActivity.class);
// startActivity(intent);
// finish();
// }
// }, 3000);

anim.setAnimationListener(new AnimationListener() {

@Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub

}

@Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub

}

@Override
public void onAnimationEnd(Animation animation) {
Intent intent = new Intent(SplashActivity.this,MainActivity.class);//跳转到splashActivity界面
startActivity(intent);
finish();

}
});
}
