Image don'T get invisible

Question

iI want that the image goes from the left side to the right side of the screen and then disappears the translateanimation works. but with

img.setVisibility(View.GONE);

everything disappears, not only the image.

public class MainActivity extends Activity
{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final ImageView img = (ImageView) findViewById(R.id.img_animation);

        wander(img);

        img.setVisibility(View.GONE);
    }

    public void wander(ImageView img)
    {
        TranslateAnimation animation = new TranslateAnimation(0.0f, 400.0f,0.0f, 0.0f);
        animation.setDuration(500);
        animation.setRepeatCount(1);
        animation.setRepeatMode(1);
        animation.setFillAfter(true);
        img.startAnimation(animation);
    }
}

I must make a correction. With this code the image is never to see.. — Joachim, Jul 19 '15 at 11:26
To catch the attention of the right people, add tags for animation and javascript — Dirk Horsten, Jul 19 '15 at 11:40
You hide the `ImageView` in `onCreate`. This's why you can't see it all the time. Animator won't show it for you if it's invisible. — Aron Lorincz, Jul 19 '15 at 12:40

Your current code starts the animation, then hides your image without waiting for the animation to finish. Use a listener like this to determine that the animation is over.

public class MainActivity extends Activity
{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final ImageView img = (ImageView) findViewById(R.id.img_animation);

        wander(img);
    }

    public void wander(ImageView img)
    {
        TranslateAnimation animation = new TranslateAnimation(0.0f, 400.0f,0.0f, 0.0f);
        animation.setDuration(500);
        animation.setRepeatCount(1);
        animation.setRepeatMode(1);
        animation.setFillAfter(false);
        animation.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {
            }

           @Override
           public void onAnimationEnd(Animation animation) {
               final ImageView img = (ImageView) findViewById(R.id.img_animation);
               img.setVisibiltiy(View.GONE);
           }

           @Override
           public void onAnimationRepeat(Animation animation) {
           }
        });
        img.startAnimation(animation);
    }
}

But i am a beginner and i don't know how or where i have to put the animationlistener in my little Programm., Can you be so kind and show me? — Joachim, Jul 20 '15 at 13:15
