如何解决Android：屏幕快照为org.webrtc.SurfaceViewRenderer
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，也会捕获其他视图，但不会捕获SurfaceViewRenderer视图的视图。
任何帮助将不胜感激。
我在下面附加我的代码，其中包括xml文件和捕获屏幕的功能。

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();
}
}
还要附加显示实际和预期行为的图像。
解决方法
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());
