我正在尝试以编程方式获取屏幕截图。相同的代码适用于不存在 SurfaceViewRenderer 的其他屏幕。即使在同一屏幕上，其他视图也会被捕获，但 SurfaceViewRenderer 视图的视图不会。

任何帮助将不胜感激。

我在下面附上了我的代码，其中包括 xml 文件和捕获屏幕的函数。

以下代码是捕获屏幕截图

public void takeScreenshot2() {
        Date now = new Date();
        android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);

        View rootView = getWindow().getDecorView().getRootView();

        rootView.setDrawingCacheEnabled(true);
        rootView.buildDrawingCache(true);
        Bitmap bm = Bitmap.createBitmap(rootView.getDrawingCache(true));
        bm = bm.copy(Bitmap.Config.RGB_565, true);
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bm.compress(Bitmap.CompressFormat.JPEG, 90, bytes);

        rootView.setDrawingCacheEnabled(false);
        File f = new File(DeviceUtil.getExternalPath()+ "/" + now + ".jpg");
        try {
            f.createNewFile();
            FileOutputStream fo = new FileOutputStream(f);
            fo.write(bytes.toByteArray());
            MessageHelper.showMessageToast(this,"Screen shot has taken successfully");

        } catch (IOException e) {
            e.printStackTrace();
        }

    }

还附上显示实际和预期行为的图像。实际和预期的行为

PixelCopy 为我工作。

 final Bitmap bitmap = Bitmap.createBitmap(remoteVideoView.getWidth(), remoteVideoView.getHeight(),
            Bitmap.Config.ARGB_8888);
    // Make the request to copy.
    PixelCopy.request(remoteVideoView, bitmap, (copyResult) -> {
        if (copyResult == PixelCopy.SUCCESS) {
            Log.e(TAG, bitmap.toString());
            saveBitmapToFile(bitmap, contactId);
        } else {
            MessageHelper.showMessageToast(WACApplication.getApp(),
                    R.string.screen_capture_failed + copyResult);
        }
    }, new Handler());
