Insert data to fragments from db. Is there any difference from common insertion method?

Question

This is my code for insertion, When i put this code to activity it is working well, but in fragment it is not working.

View.OnClickListener addOnClickListener=new OnClickListener()
 {
     @Override
     public void onClick(View v) {

         String HouseName = "home";//txtName.getText().toString();
        Integer HouseNumber =12; //Integer.parseInt(txtNumber.getText().toString());
         String TableName="home_details";

         dbhelper=new DatabaseHelper(context);
         sqlitedatabase=dbhelper.getWritableDatabase();
         dbhelper.insertHome(HouseName, HouseNumber, sqlitedatabase);
        // Toast.makeText(getActivity().getBaseContext() ,"Logout", Toast.LENGTH_SHORT).show();
         dbhelper.close();

     }
 };

fragment stops forcefully when i click on insert button... don't know which line. — Aadhi, Oct 08 '16 at 07:04

try following code:

dbhelper = new DataBaseHelper(getActivity());

I think the NullPointException is because of context is null.

That is assuming the null-pointer occurs in the code shown in the question – OneCricketeer Oct 08 '16 at 07:05
