Android中的自定义导航抽屉

Question

I have a requirement, where when the navigation drawer slides open, it should appear to be below the Main Activity with portion of the Main Activity being visible at the right and appear on top of the drawer. I am able to this achieve partially using scaling. But the navigation drawer beneath the Main Activity is not coming. Is there any way to achieve this. Below is my code.

 public void onDrawerSlide(@NonNull View drawerView, float slideOffset) {
                final float diffScaledOffset = slideOffset*(1 - 0.9f);
                final float offsetScale = 1 - diffScaledOffset;
                contentView.setScaleX(offsetScale);
                contentView.setScaleY(offsetScale);
                final float xOffset = drawerView.getWidth()* slideOffset;
                final float xOffsetDiff = contentView.getWidth() * diffScaledOffset / 2;
                final float xTranslation = xOffset - xOffsetDiff;
                contentView.setTranslationX(xTranslation);
            }

public void onDrawerSlide(@NonNull View drawerView, float slideOffset) {
                int width = getResources().getDimensionPixelSize(R.dimen.navigation_view_width);
                float moveFactor = (width * slideOffset);
                contentView.setTranslationX(moveFactor);
            }

try this , i think it will help
