我有一個ImageButton
在android中點擊旋轉。問題在於,當用戶點擊它並繼續到下一行的新Activity時,它不會完成旋轉。我嘗試過Thread.sleep(..)
和wait(..)
,但是在動畫開始之前將RotateAnimation(..)
與這些實際睡眠一起。RotateAnimation不會等待按鈕旋轉之前啓動活動
我需要的動畫實際完成,然後進行startActivity(new Intent(..))
下面的代碼
amazingPicsButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
amazingPicsSound = createRandButSound();
amazingPicsSound.start();
rotateAnimation(v);
startActivity(new Intent("com.jasfiddle.AmazingInterface.AMAZINGPICS"));
}
});
}
/** function that produces rotation animation on the View v.
* Could be applied to button, ImageView, ImageButton, etc.
*/
public void rotateAnimation(View v){
// Create an animation instance
Animation an = new RotateAnimation(30, 360, v.getWidth()/2, v.getHeight()/2);
// Set the animation's parameters
an.setDuration(20); // duration in ms
an.setRepeatCount(10); // -1 = infinite repeated
// an.setRepeatMode(Animation.REVERSE); // reverses each repeat
an.setFillAfter(true); // keep rotation after animation
v.setAnimation(an);
// Apply animation to the View
}
