Android ResideMenu library, bottom of Fragment has Cropping issue

问题

https://www.dropbox.com/s/lykyutdlo6386il/nexus%205%202.png?dl=0

This picture is captured by nexus 5. As you can see the gap between top and bottom of screen is different. Android Logo is cropped when the side menu is closed. Part of the bottom screen is hidden under native navigation bar.

On the other hand, this picture is captured by galaxy s5 mini. You may notice the gap between top and below of the screen is the same amount. There is no problem at all.

It is the same ResideMenu library with different devices and android OS (lollipop & kitkat). I look at the layouts (residemenu.xml) to find something wrong; but everything seems correct to me. I couldn't find any solution to this problem. Is there any way to fix to scale main fragment correctly (same margin from top and bottom)? Please help me.

Edit:

This link is the issue that I'm talking about with it's solution.

I solved this issue by editing a method "ResideMenu.java" in ResideMenu library.

I made a few changes in a method called "fitSystemWindows"

before I made changes:

 @Override
    protected boolean fitSystemWindows(Rect insets) {

        this.setPadding(viewActivity.getPaddingLeft() + insets.left, viewActivity.getPaddingTop() + insets.top,
                viewActivity.getPaddingRight() + insets.right, viewActivity.getPaddingBottom() + insets.bottom);
        insets.left = insets.top = insets.right = insets.bottom = 0;
        return true;
    }

after I made changes:

@Override
    protected boolean fitSystemWindows(Rect insets) {
        int bottomPadding=insets.bottom;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Resources resources = getResources();
            int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
            if (resourceId > 0) {
                bottomPadding += resources.getDimensionPixelSize(resourceId);
            }
        }
        this.setPadding(viewActivity.getPaddingLeft() + insets.left, viewActivity.getPaddingTop() + insets.top,
                viewActivity.getPaddingRight() + insets.right, viewActivity.getPaddingBottom() + bottomPadding);
        insets.left = insets.top = insets.right = insets.bottom = 0;
        return true;
    }

This change solve my issue, part of the bottom screen hidden under native navigation bar.

I hope this solution be helpful anyone who encounter this kind of issue. Cheers.

Found Most stable solution

    public Point getNavigationBarSize(Context context) {

      Point appUsableSize = getAppUsableScreenSize(context);
      Point realScreenSize = getRealScreenSize(context);
     // navigation bar on the right
    if (appUsableSize.x < realScreenSize.x) {
        return new Point(realScreenSize.x - appUsableSize.x,    appUsableSize.y);
    }

    // navigation bar at the bottom
    if (appUsableSize.y < realScreenSize.y) {
        return new Point(appUsableSize.x, realScreenSize.y - appUsableSize.y);
    }

    // navigation bar is not present
    return new Point();
   }


  public Point getAppUsableScreenSize(Context context) {

      WindowManager windowManager = (WindowManager)context.getSystemService(Context.WINDOW_SERVICE);
    Display display = windowManager.getDefaultDisplay();
    Point size = new Point();
    display.getSize(size);
    return size;
}

   public Point getRealScreenSize(Context context) {

    WindowManager windowManager = (WindowManager)  
    context.getSystemService(Context.WINDOW_SERVICE);
    Display display = windowManager.getDefaultDisplay();
    Point size = new Point();

    if (Build.VERSION.SDK_INT >= 17) {
        display.getRealSize(size);
    } else if (Build.VERSION.SDK_INT >= 14) {
        try {
            size.x = (Integer) Display.class.getMethod("getRawWidth").invoke(display);
            size.y = (Integer) Display.class.getMethod("getRawHeight").invoke(display);
        } catch (IllegalAccessException e) {} catch (InvocationTargetException e) {} catch (NoSuchMethodException e) {}
    }

    return size;
}

And set padding of main layout

setPadding(getPaddingLeft(),
getPaddingTop(), getPaddingRight(),
getNavigationBarSize(getContext()).y);

Edit : Keep this code inside attachToActivity() method of ResideMenu.java

 if (getNavigationBarSize(getContext()).x > 0 && getNavigationBarSize(getContext()).y > 0) {
        this.postDelayed(new Runnable() {
            @Override
            public void run() {
                setPadding(getPaddingLeft(),
                        getPaddingTop(), getPaddingRight(),
                        getNavigationBarSize(getContext()).y);
            }
        }, 100);
    }

comment or Remove this method and your bottom of Fragment has Cropping issue solved.

fitSystemWindows()

Overrides deprecated method in 'android.view.View' as of API 20: Android 4.4W (KitKat Wear) Inspection info: This inspection reports where deprecated code is used in the specified inspection scope.

I had this same issue and I solved this by editing a method in ResideMenu library.

Inside the library, you can acess a java class named "ResideMenu.java".

Edit the method as like this.

 private void setScaleDirection(int direction){

    int screenWidth = getScreenWidth();
    float pivotX;
    float pivotY = getScreenHeight() * 0.5f;

    if (direction == DIRECTION_LEFT){
        scrollViewMenu = scrollViewLeftMenu;
        pivotX  = screenWidth * 2.2f;
    }else{
        scrollViewMenu = scrollViewRightMenu;
        pivotX  = screenWidth * -0.5f;
    }

    ViewHelper.setPivotX(viewActivity, pivotX);
    ViewHelper.setPivotY(viewActivity, pivotY);
    ViewHelper.setPivotX(imageViewShadow, pivotX);
    ViewHelper.setPivotY(imageViewShadow, pivotY);
    scaleDirection = direction;
}

Here i made changes to
