How TO Change Activity To Fragment

android, android-fragments, java

Solution

Just understand some steps then you can easily convert a Activity to Fragment now and also in future..:

First of all instead of extending `Activity`,just extend `Fragment`..

Ex: `public class Welcome extends Fragment{`

Then override `onCreateView()`..

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
.....
}

Then inflate the layout through LayoutInflater and asign to a `View` for further use in subview inilialization..

like: `View mView = inflater.inflate(R.layout.welcome, null);`

Then initialize all sub views with the help of main view..like:

 ImageView image = (ImageView) mView.findViewById(R.id.imageView1);
 TextView userfullname = (TextView) mView.findViewById(R.id.userfullname);

Now do all your tasks same like activity here..

The important thing.. Use `getActivity()` in the place of `context`..

Ex: `Toast.maketext(getActivity(), "...", Toast.LENGTH_LONG).show();`
