Vielen Dank für die aufmerksamkeit: D Helfen Sie mir damit, wie Sie können pls. Also hier ist was ich tun möchte. Ich habe vier Fragmente und eine Aktivität. Ich spiele ein Live-Video im ersten Fragment, und es funktioniert gut. Aber wenn ich das erste Fragment durch ein anderes ersetze, spielt das Video des ersten Fragments immer noch im Hintergrund. Was ich machen möchte, ist dieses Video in all meinen Fragmenten zu spielen, aber mit unterschiedlichen Größen und ohne gegenseitige Beeinflussung. Wie kann ich das machen? Hier ist mein Code.wenn ersetzen ein fragment video ist noch spielen hintergrund in android
Erster Teil des Code
public class FTop2 extends Fragment {
String Tag = "FTop2";
CallbackManager callbackManager;
ShareDialog shareDialog;
ProgressDialog progressDialog;
public FTop2() {}
protected void facebookSDKInitialize() {
FacebookSdk.sdkInitialize(getContext());
callbackManager = CallbackManager.Factory.create();
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
facebookSDKInitialize();
Twitter.initialize(getActivity());
}
private class HttpUrl extends AsyncTask<Integer, Void, ArrayList<LiveUrl>> {

}
@Override
protected void onPostExecute(ArrayList<LiveUrl> result) {
for (int i=0; i<result.size();i++) {
String txt = result.get(i).url;
Log.e("play url", Config.B64decodeStr(txt));
}
VideoView vid = (VideoView) getView().findViewById(R.id.videoView);
String vid_url = Config.B64decodeStr(result.get(0).url);
Uri vid_uri = Uri.parse(vid_url);
vid.setVideoURI(vid_uri);
vid.start();

vid_control.setAnchorView(vid);
vid.setMediaController(vid_control);
if (progressDialog.isShowing()) {
progressDialog.hide();
}
}
}
@Override
public View onCreateView(LayoutInflater i, ViewGroup c,Bundle s) {
Bundle bundle = this.getArguments();
final int channel= bundle.getInt("channel");

shareDialog = new ShareDialog(this);
View view = i.inflate(R.layout.f_top2, c, false);
progressDialog = Config.getProgressDialog(getContext());

new HttpUrl().execute();
}else {

}
