1. 渐入动画
// Request the next activity transition (here starting a new one).
startActivity(new Intent(Animation.this, AlertDialogSamples.class));
// Supply a custom animation. This one will just fade the new
// activity on top. Note that we need to also supply an animation
// (here just doing nothing for the same amount of time) for the
// old activity to prevent it from going away too soon.
overridePendingTransition(R.anim.fade, R.anim.hold);
R.anim.fade和 R.anim.hold.如下：

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
要有版本限制，低版本是不支持的。
// Create a more complicated animation, involving transformations

// Request the activity be started, using the custom animation options.
startActivity(new Intent(Animation.this, AlertDialogSamples.class), opts.toBundle());
中心快速同理如上。
中心缩放的2种形式：
// Create a scale-up animation that originates at the button
// being pressed.
ActivityOptions opts = ActivityOptions.makeScaleUpAnimation(
v, 0, 0, v.getWidth(), v.getHeight());
// Request the activity be started, using the custom animation options.
startActivity(new Intent(Animation.this, AlertDialogSamples.class), opts.toBundle());
有版本限制，如上。
// Create a thumbnail animation. We are going to build our thumbnail
// just from the view that was pressed. We make sure the view is
// not selected, because by the time the animation starts we will
// have finished with the selection of the tap.
v.setDrawingCacheEnabled(true);
v.setPressed(false);
v.refreshDrawableState();
Bitmap bm = v.getDrawingCache();
Canvas c = new Canvas(bm);
//c.drawARGB(255, 255, 0, 0);
ActivityOptions opts = ActivityOptions.makeThumbnailScaleUpAnimation(
v, bm, 0, 0);
// Request the activity be started, using the custom animation options.
startActivity(new Intent(Animation.this, AlertDialogSamples.class), opts.toBundle());
v.setDrawingCacheEnabled(false);
有版本限制，如上所示。
