if (metrics.widthPixels > metrics.heightPixels)

//---landscape mode---
Fragment1 fragment1 = new Fragment1() ;
// android.R.id.content refers to the content
// view of the activity
fragmentTransaction.replace(

fragmentTransaction.replace(

//fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();




getting error in the replace method
-The method replace(int, Fragment) in the type FragmentTransaction is not applicable for the arguments (int, Fragment1)


i replaced display class getWidth(),and getHeight() with DisplayMetrics class due to dreprication (hoping after the solution for the replace it will work,havnt checked it somewhere else)
