Как создать такую анимацию?

private void setWeigtnMemory(float k,int visibility){
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
        ViewGroup.LayoutParams.MATCH_PARENT, 0);
        float v = context.getResources().getDisplayMetrics().density;
        params.weight = k;
        params.topMargin = (int) (20*v);
        params.leftMargin = (int) (10*v);
        params.rightMargin = (int) (10*v);
        relativeMemory.setVisibility(visibility);
        relativeWeigth.setLayoutParams(params);
    }
