I have implemented an activity with VideoView layout that plays a livestream video.
I want to set a double click listener on that VideoView and make this VideoView play in full screen mode but without the need to start a new activity.
Is this possible or is it mandatory to launch an activity?
no, it`s not a mandatory to launch new activity.
For example in your double click method u can set orientation to landscape and dynamically change size of VideoView to make it fit whole screen.
It may look like this:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
//this will get screen metrics
DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int displayHeight = displayMetrics.heightPixels;
int displayWidth = displayMetrics.widthPixels;
//and then set it to your videoView
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) videoView.getLayoutParams();//it may be another layout params in tour case
params.height = displayHeight;
params.width = displayWidth;
videoView.setLayoutParams(params);
