[Android][Resolved] Cannot resolve method getWindowManager

This is the code helped me get the screen width at Activity. However, when i move that from Activity to Fragment, it doesn't work anymore.

After some searching on internet, i found this code could help solve my problem:

DisplayMetrics metrics = new DisplayMetrics();
getActivity().getWindowManager().getDefaultDisplay().getMetrics(metrics);
double screenWidth = metrics.widthPixels;

When i was still extends the Activity class, i can use getWindowManager() method since that is a method in Activity class. you can use that within the sub-class.

To use the getWindowManager() method in fragment, you need to use the getActivity() to get the Activity which your fragment is currently associated with.
