@Override
protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
    if (mLayoutDirection == LAYOUT_DIRECTION_RTL) {
        // When the layout direction is RTL, we expect Yoga to give us a layout
        // that extends off the screen to the left so we re-center it with left=0
        int newLeft = 0;
        int width = right - left;
        int newRight = newLeft + width;
        setLeft(newLeft);//from  w w w.  ja v a 2s  .c  o  m
        setRight(newRight);

        // Call with the present values in order to re-layout if necessary
        HorizontalScrollView parent = (HorizontalScrollView) getParent();
        // Fix the ScrollX position when using RTL language
        int offsetX = parent.getScrollX() + getWidth() - mCurrentWidth;
        parent.scrollTo(offsetX, parent.getScrollY());
