If I extend activity in my app I can get width and height:
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int wwidth = displaymetrics.widthPixels;
or
Display display = getWindowManager().getDefaultDisplay();
stageWidth = display.getWidth();
stageHeight = display.getHeigth();
But at present I extend fragment and I can't use the above code to get the width.
This will give you what you want without needing for context or view:
import android.content.res.Resources;
int width = Resources.getSystem().getDisplayMetrics().widthPixels;
int height = Resources.getSystem().getDisplayMetrics().heightPixels;
This code also works with Fragments:
int width = getResources().getConfiguration().screenWidthDp;
int height = getResources().getConfiguration().screenHeightDp;
For comparing orientation:
if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){...}
