Question

I want to move an image from 0,0 to 100,100 on android. I’m using translate animation to do so:

public void moveImage() {
    // move image from 0,0 to 100,100
    mAnimationTranslate = new TranslateAnimation(0, 100, 0, 100);
    mAnimationTranslate.setDuration(1000);
    mAnimationTranslate.setAnimationListener(this);
    this.startAnimation(mAnimationTranslate);
}

public void onDraw (Canvas canvas) {
    super.onDraw(canvas);
    canvas.drawBitmap(bmp, x, y, null);
}

public void onAnimationEnd(Animation animation) {
    // stop animation and draw the image at 100,100
    x = 100;
    y = 100;
}

The problem is when the animation finishes at 100,100, the image will move to 200,200 for a short time and back to 100,100 in the end. Is there any problem in my code? How to let the image stop at 100,100 correctly?

Answer 1

I think you need to use

animation.setFillAfter(true); //to retain the properties after the animation finishes.

There is no need for the onAnimationEnd event.
Not sure why it’s moving to 200, 200 though.
