Android Fragment Isn't Accepting Setcontentview

I am trying to use fragments to make swiped tabs by tablayouts (one activity with three tabs), I made three Java files for the tree tabs and the corresponding xml files as the belo

Solution 1:

You can not call setContentView in Fragment. You should override the onCreatView method of fragment and inflate your layout as follows:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
         View v= inflater.inflate(R.layout.tab_fragment_2, container, false);

        //to get view like textview, button etc use v.findViewById(yourid)TextViewtextView= v.findViewById(R.id.textView2);
        return v;
    }
}.

Solution 2:

For a Fragment you

• override onCreateView
• Inflate a view
• use findViewById on the view reference

• return the view

  public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
  
      Viewview= inflater.inflate(R.layout.my_fragment, container, false);
      Toolbartoolbar= (Toolbar) view.findViewById(R.id.toolbar);
      ...
      return view;
  }
