After the TranslateAnimation animation is moved, the x y coordinates of the ImageView itself will not change.

For example:

TranslateAnimation (float fromXDelta, float toXDelta, float fromYDelta, float toYDelta) is relative to its own move, but after moving it, the x y value of the View itself of the animation remains unchanged, when you manually set coordinates, as shown in figure

View. setX (x );

View. setY (y );

The display position of the view is not in the current x and y coordinates, but in the position after anim is executed relative to the position, and the event can be triggered at this position.

Solution: Use Animation listeners

Instance:

ImageView img = new ...... Create ImageView

TranslateAnimation anim = new TranslateAnimation (0, x, 0, y );

Anim. setFillAfter (true); // sets the value to be moved and left in the current position. No result is returned.

Anim. setDuration (500 );

Anim. setInterpolator (macitator, android. R. anim. accelerate_decelerate_interpolator );

Img. startAnimation (anim );

// Set the animation listener, clear the img animation when the listener ends, and set the img x and y coordinates.

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 ){

// TODO Auto-generated method stub

Img. clearAnimation ();

Img. setX (x );

Img. setY (y );

}

});
