错误的图纸

我的代码：

@Override
protected void onDraw(Canvas canvas) {
    if (mCurrentBitmapDrawable != null) {
        if (mTopLeft == 0 && mTopRight == 0 && mBottomLeft == 0 && mBottomRight == 0) {
            Log.d("CustomImageView-def", "mTopLeft = " + String.valueOf(mTopLeft));
            super.onDraw(canvas);
            return;
        }
        Log.d("CustomImageView-cust", "mTopLeft = " + String.valueOf(mTopLeft));
        mBitmapShader = new BitmapShader(mCurrentBitmapDrawable.getBitmap(), Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
        paint.setAntiAlias(true);
        paint.setShader(mBitmapShader);

        mRoundRectShape.resize(getWidth(), getHeight());
        mRoundRectShape.draw(canvas, paint);
    }
}
