我有一个RotateAnimation附加到一个ImageButton点击旋转它并使用OnAnimationEnd启动一个新的活动。
问题是它不工作。在我关闭我的应用程序并返回后，我在里面new Activity(..)，当我返回时，动画就会执行。我希望动画发生，然后启动新的活动。
出于某种原因，在使用相同的代码之前它工作得非常好，但我不知道，一些微不足道的改变可能会影响它。
这是代码
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.menu);
ImageButton amazingPicsButton = (ImageButton) findViewById(R.id.amazingPics),
setViewOnClick(amazingPicsButton, new Intent("com.jasfiddle.AmazingInterface.AMAZINGPICS"));
}
/**
* Generic OnClick setter method for giving various View objects a click listener
* @param b
* @param intent
*/
private <B> void setViewOnClick(B b, final Intent intent){
((View) b).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
amazingPicsSound = createRandButSound();
amazingPicsSound.start();
rotateAndNewActivity(v, intent);
}
});
}
/** function that produces rotation animation on the View v.
* Could be applied to button, ImageView, ImageButton, etc.
*/
private void rotateAndNewActivity(View v, final Intent intent){
// Create an animation instance
Animation an = new RotateAnimation(30, 360, v.getWidth()/2, v.getHeight()/2);
an.setDuration(50); // duration in ms
an.setRepeatCount(3); // -1 = infinite repeate
/*we override the Animation an object to include the start of an new Activity
at the end of animation */
an.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
}
//start the activity onAnimationEnd
@Override
public void onAnimationEnd(Animation animation) {
// TODO Auto-generated method stub
startActivity(intent);
}
});
// Set the animation's parameters
v.setAnimation(an);
}
