Answer 1

So, the solution to my problem is here (for all of the new android developers, like me, who might need this for their apps):

public class MainActivity extends Activity {

    Animation           _translateAnimation;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        _translateAnimation = new TranslateAnimation(TranslateAnimation.ABSOLUTE, 0f, TranslateAnimation.ABSOLUTE, -300f, TranslateAnimation.ABSOLUTE, 0f, TranslateAnimation.ABSOLUTE, 0f);
        _translateAnimation.setDuration(8000);
        _translateAnimation.setRepeatCount(-1);
        _translateAnimation.setRepeatMode(Animation.REVERSE); // REVERSE
        _translateAnimation.setInterpolator(new LinearInterpolator());
        ImageView img = (ImageView) findViewById(R.id.img);
        img.startAnimation(_translateAnimation);
    }
}

and the layout:

just make sure your image is big/high enough to fit the screen, and is (+300dp) wider than the screen width (or adjust the code above).

Happy coding ;)
