I want to move some view from any position to center of screen and scale in parallel. If that's too complicated, translate and scale sequentially is also acceptable. But neither I could achieve. I think it's the problem with the pivot point. But sorry I found no solution. Please help. Maybe it's easy to those who develop games, about which I did nothing.
Below is my code:
private void moveViewToScreenCenter( final View view ){
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics( dm );
int statusBarOffset = dm.heightPixels - rootLayout.getMeasuredHeight();
int originalPos[] = new int[2];
view.getLocationOnScreen( originalPos );
int xDelta = (dm.widthPixels - view.getMeasuredWidth())/2 - originalPos[0];
int yDelta = (dm.heightPixels - view.getMeasuredHeight())/2 + statusBarOffset - originalPos[1];
AnimationSet animSet = new AnimationSet(true);
animSet.setFillAfter(true);
animSet.setDuration(1000);
animSet.setInterpolator(new BounceInterpolator());
TranslateAnimation translate = new TranslateAnimation( 0, xDelta , 0, yDelta);
animSet.addAnimation(translate);
ScaleAnimation scale = new ScaleAnimation(1f, 2f, 1f, 2f, ScaleAnimation.RELATIVE_TO_PARENT, .5f, ScaleAnimation.RELATIVE_TO_PARENT, .5f);
animSet.addAnimation(scale);
view.startAnimation(animSet);
}
Update: code above can handle imageview from top left region, those from bottom right region go diagonally through the screen and disappear.
After quite a few hopeless trials, I made it, which is too astonishing.
Below is the code, it can be used to move any view in a layout to the center of that layout:
private void moveViewToScreenCenter( final View view ){
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics( dm );
int originalPos[] = new int[2];
view.getLocationOnScreen( originalPos );
int xDelta = (dm.widthPixels - view.getMeasuredWidth() - originalPos[0])/2;
int yDelta = (dm.heightPixels - view.getMeasuredHeight() - originalPos[1])/2;
AnimationSet animSet = new AnimationSet(true);
animSet.setFillAfter(true);
animSet.setDuration(1000);
animSet.setInterpolator(new BounceInterpolator());
TranslateAnimation translate = new TranslateAnimation( 0, xDelta , 0, yDelta);
animSet.addAnimation(translate);
ScaleAnimation scale = new ScaleAnimation(1f, 2f, 1f, 2f, ScaleAnimation.RELATIVE_TO_PARENT, .5f, ScaleAnimation.RELATIVE_TO_PARENT, .5f);
animSet.addAnimation(scale);
view.startAnimation(animSet);
}
The core idea is:
AnimationSet animationSet = new AnimationSet(true);
animationSet.addAnimation(
new TranslateAnimation(0f, 64f, 0f, 32f),
new ScaleAnimation(1f, 0f, 1f, 0f, ScaleAnimation.RELATIVE_TO_PARENT, 0f, ScaleAnimation.RELATIVE_TO_PARENT, 0f););
myView.startAnimation(
animationSet);
