android-layout - 嵌套在主布局中的特定布局的屏幕截图

Question

我想截取嵌套（中间）主布局的布局的屏幕截图。我正在使用以下代码：

public static Bitmap captureScreen(View v) {

        Bitmap bitmap = null;


        try {
            if (v != null) {
                int width = v.getWidth();
                int height = v.getHeight();

                screenshot = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);
                v.draw(new Canvas(screenshot));

            }
        } catch (Exception e) {

            Log.d("captureScreen", "Failed");
        }

        return bitmap;
    }

在按钮点击它会像：

captureScreen(midlayout);
