• Getters & Setters:

  mSlidingDrawerLayout.setLeftDrawerWidthPercent(
          SlidingDrawerLayout.UNSPECIFIED_DRAWER_WIDTH_PERCENT /* default value */);
  mSlidingDrawerLayout.setRightDrawerWidthPercent(
          SlidingDrawerLayout.UNSPECIFIED_DRAWER_WIDTH_PERCENT);
  mSlidingDrawerLayout.setStartDrawerWidthPercent(0.8f);
  mSlidingDrawerLayout.setEndDrawerWidthPercent(0.9f);
  
  mSlidingDrawerLayout.setDrawerEnabledInTouch(Gravity.START, true /* default value */);
  mSlidingDrawerLayout.setDrawerEnabledInTouch(mEndDrawer, true);
  
  mSlidingDrawerLayout.setDuration(256 /* in milliseconds */);
  mSlidingDrawerLayout.setContentSensitiveEdgeSize(
          (int) (50f * getResources().getDisplayMetrics().density + 0.5f) /* in pixels */);
  mSlidingDrawerLayout.setContentFadeColor(/* ColorInt */ 0xFF_FF4081);

• Open/Close a Drawer:

  mSlidingDrawerLayout.openDrawer(Gravity.START, /* animate */ true);
  mSlidingDrawerLayout.openDrawer(mStartDrawer, /* animate */ true);
  mSlidingDrawerLayout.closeDrawer(/* animate */ true);

• Listener Related:

  final SlidingDrawerLayout.OnDrawerScrollListener listener = new SlidingDrawerLayout.OnDrawerScrollListener() {
      @Override
      public void onDrawerOpened(@NonNull SlidingDrawerLayout parent, @NonNull View drawer) {
      }
  
      @Override
      public void onDrawerClosed(@NonNull SlidingDrawerLayout parent, @NonNull View drawer) {
      }
  
      @Override
      public void onScrollPercentChange(@NonNull SlidingDrawerLayout parent,
                                        @NonNull View drawer, float percent) {
      }
  
      @Override
      public void onScrollStateChange(@NonNull SlidingDrawerLayout parent,
                                      @NonNull View drawer, int state) {
      }
  };
  mSlidingDrawerLayout.addOnDrawerScrollListener(listener);
  mSlidingDrawerLayout.removeOnDrawerScrollListener(listener);
  mSlidingDrawerLayout.clearOnDrawerScrollListeners();

app:widthPercent_leftDrawer="unspecified"
