Android FragmentTransaction: How to generate an overlay slide in and move existing Fragement to left

Question

I\'m trying to do the following. Create a new Fragement B (Menu), slide it in from the right, and i want to move (no hide or replace!) the already shown Fragment A to the left.

Solution:

Create Relative Layout with overlapping fragments:

and simply call .translationX(-1 * mScreenWidth) (mScreenWidth is my ScreenWidth minus the gap you want).

            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB_MR1) {
                ((RelativeLayout) findViewById(R.id.front_frame)).animate()
                    .translationX(-1 * mScreenWidth);
            } else {
                TranslateAnimation slideOut = new TranslateAnimation(0, -1
                    * mScreenWidth, 0, 0);
                slideOut.setDuration(getResources().getInteger(
                    R.integer.animation_transistion_length_short));
                slideOut.setFillEnabled(true);

                slideOut.setAnimationListener(new AnimationListener() {

                    @Override
                    public void onAnimationStart(Animation animation) {}


                    @Override
                    public void onAnimationRepeat(Animation animation) {}


                    @Override
                    public void onAnimationEnd(Animation animation) {
                        RelativeLayout mView = (RelativeLayout) findViewById(R.id.front_frame);
                        int[] pos = { mView.getLeft() - mScreenWidth,
                            mView.getTop(), mView.getRight(),
                            mView.getBottom() };
                        mView.layout(pos[0], pos[1], pos[2], pos[3]);
                    }
                });

                ((RelativeLayout) findViewById(R.id.front_frame))
                    .startAnimation(slideOut);
            }
