截取布局Android CardView的截图

Question

我试图抓住我的一个布局，但在下面的屏幕截图中获得黑色边框。 我该如何删除它？

我的截屏代码如下所示

private void takeScreenshot() {
    Date now = new Date();
    android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);

    try {
        // image naming and path  to include sd card  appending name you choose for file
        String mPath = Environment.getExternalStorageDirectory().toString() + "/" + now + ".jpg";

        // create bitmap screen capture
        View v1= findViewById(R.id.quoteViewPager); 
        v1.getRootView();
        v1.setDrawingCacheEnabled(true);
        Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
        v1.setDrawingCacheEnabled(false);

        File imageFile = new File(mPath);

        FileOutputStream outputStream = new FileOutputStream(imageFile);
        int quality = 100;
        bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
        outputStream.flush();
        outputStream.close();

        openScreenshot(imageFile);

    } catch (Throwable e) {
        // Several error may come out with file handling or OOM
        e.printStackTrace();
    }
}

谢谢

实际上，我没有得到你的代码，

View v1= findViewById(R.id.quoteViewPager); 
v1.getRootView();

它应该是 ：

v1 = v1.getRootView();

希望它能帮到你:)
