Question

我指的是this Stack Overflow问题，以便在NavigationView中实现模糊背景，并从右侧打开抽屉。问题在于BlurAndDimView的右重力。

当我将NavigationView的重力设置为正确时，抽屉正常工作但模糊的视图仍保持在左侧。当我设置BlurAndDimView右侧的重力时，它进入中心并且抽屉消失了。

我还尝试更改public void handleScroll(float xOffset)类的方法public void setImage(Bitmap bmp, int downSampling)和BlurAndDimView，如下所示 -

public void handleScroll(float xOffset) {
        if (image != null) {
            rectSrc.left = getWidth()-(int) (image.getWidth() * xOffset);
            rectDst.left = rectSrc.left * downSampling;
            rectRest.right = rectDst.left;

            /*rectSrc.right = (int) (image.getWidth() * xOffset);
            rectDst.right = rectSrc.right * downSampling;
            rectRest.left = rectDst.right;*/

            dimPaint.setAlpha((int) (xOffset * MAX_DIM_ALPHA));
            invalidate();
        }
    }

    public void setImage(Bitmap bmp, int downSampling) {
        Bitmap cropped = Bitmap.createBitmap(bmp, 0, 0, menuWidth / downSampling, getHeight() / downSampling);
        this.image = Blur.fastblur(getContext(), cropped, BLUR_RADIUS);
        /*rectSrc = new Rect(0, 0, bmp.getWidth(), bmp.getHeight());
        rectDst = new Rect(0, 0, menuWidth, getHeight());
        rectRest = new Rect(menuWidth, 0, getWidth(), getHeight());*/

        rectSrc = new Rect(0, 0, bmp.getWidth(), bmp.getHeight());
        rectDst = new Rect(getWidth() - menuWidth, 0, getWidth(), getHeight());
        rectRest = new Rect(0, 0, getWidth() - menuWidth, getHeight());

        this.downSampling = downSampling;
        invalidate();
    }

但它没有用。抽屉消失了！感谢您的帮助。
