[英]Error in onActivityResult following migration of StartActivityForResult
[英]use onActivityResult instead of startActivityFOrResult
private void toggleScreenShare(View v) {
ToggleButton toggleButton=(ToggleButton) v;
if(toggleButton.isChecked()){
initRecorder();
recordScreen();
}
else {
mMediaRecorder.stop();
mMediaRecorder.reset();
stopRecordScreen();
mVideoView.setVisibility(View.VISIBLE);
mVideoView.setVideoURI(Uri.parse(mVideoUrl));
mVideoView.start();
}
}
private void recordScreen() {
if(mediaProjection==null){
** startActivityForResult(mMediaProjectionManager.createScreenCaptureIntent(),REQUEST_CODE);**
return;
}
mVirtualDisplay=createVirtualDisplay();
mMediaRecorder.start();
}
這是我的代碼,我想在粗體中使用 onActivityResult,因為不推薦使用 StartActivityFOrResult,誰能幫我寫這個
我試了很多次,想要代碼
這部分代碼將為您提供意圖的結果。
/**
* In your activity
* this will get you the result from the other intent.
* I do not know, what exactly you are exactly doing there.
* So you no longer need technically the request code.
*/
private final ActivityResultLauncher<Intent> yourLauncher = registerForActivityResult(new ActivityResultContracts.StartActivityForResult(), new ActivityResultCallback<ActivityResult>() {
@Override
public void onActivityResult(ActivityResult result) {
Intent intentData = result.getData();
if (intentData == null) return;
intentData.getBooleanExtra("BOOLEAN", false);
}
});
這部分代碼將以您想要的意圖調用您的啟動器。
yourLauncher.launch(mMediaProjectionManager.createScreenCaptureIntent());
希望這個簡單的例子能啟發方法。
