隐藏在导航栏android后面的视图

Question

I am using Sliding Activity, the View is not fitting to the screen, it is hiding behind the Navigation Bar.

I tried ,

<item name="android:fitsSystemWindows">true</item> 
<item name="android:windowDrawsSystemBarBackgrounds">false</item>

but nothing works.

here Snackbar is hiding behind the Navigation Bar:

Hey there best practive would be to use tha NavigationDrawer , but for your problem create a class CustomSlidingMenu which extends SlidingMenu and Override methods like this. Then use the CustomSlidingMenu instead of SlidingMenu and it should work fine

public class CustomSlidingMenu extends SlidingMenu {
    private boolean mActionbarOverlay = false;

    public CustomSlidingMenu(Context context) {
        super(context);
    }

    public CustomSlidingMenu(Activity activity, int slideStyle) {
        super(activity, slideStyle);
    }

    public CustomSlidingMenu(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomSlidingMenu(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @SuppressLint("NewApi")
    @Override
    protected boolean fitSystemWindows(Rect insets) {
        if (mActionbarOverlay) return true;

        setMyPadding(insets);
        return true;
    }

    @TargetApi(Build.VERSION_CODES.KITKAT_WATCH)
    @Override
    public WindowInsets onApplyWindowInsets(WindowInsets insets) {
        if (mActionbarOverlay) return insets.consumeSystemWindowInsets();

        Rect rect = new Rect(
                insets.getSystemWindowInsetLeft(),
                insets.getSystemWindowInsetTop(),
                insets.getSystemWindowInsetRight(),
                insets.getSystemWindowInsetBottom()
        );

        setMyPadding(rect);

        return insets.consumeSystemWindowInsets();
    }

    private void setMyPadding(Rect rect) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            WindowManager manager = (WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE);
            switch (manager.getDefaultDisplay().getRotation()) {
                case Surface.ROTATION_90:
                case Surface.ROTATION_270:
                    rect.right += getNavBarWidth();
                    break;
                case Surface.ROTATION_180:
                    rect.top += getNavBarHeight();
                    break;
                default:
                    rect.bottom += getNavBarHeight();
            }
        }

        setPadding(
                rect.left, rect.top, rect.right, rect.bottom
        );
    }

    private int getNavBarWidth() {
        return getNavBarDimen("navigation_bar_width");
    }

    private int getNavBarHeight() {
        return getNavBarDimen("navigation_bar_height");
    }

    private int getNavBarDimen(String resourceString) {
        Resources r = getResources();
        int id = r.getIdentifier(resourceString, "dimen", "android");
        if (id > 0) {
            return r.getDimensionPixelSize(id);
        } else {
            return 0;
        }
    }
}

I'm assuming that you use AppCompat with my approach, so the reason is that the paddings set by the SlidingMenu are in conflict with the AppCompat configurations and Override them.
