Question

See more:

I use "tab bar" to separate main screen(Fragment1,2,3). In one of my main screen(MainActivity), I try to make more page. So I use Inent to link from Fragment 1_1 to Fragment1_2. I doubt it about extends Fragment that why I can't use any method on this class.

Java

public class Fragment1_1 extends Fragment {
	
	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		
		 return inflater.inflate(R.layout.fragment1_1, null);
	}
	

	public void btnNext(View view){
		Intent nextScreen = new Intent(getApplicationContext(),Fragment1_2.class);
		 startActivity(nextScreen);
	}
}

getApplicationContext() error. Somebody know How to OnClick like this page? pls help and thanks a lot.

when I use "extends fragment" many stuff dun work.

It's THE tutorial - and actually a pretty good one.

Eerven 21-Jul-14 4:57am

public class Fragment1_1 extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment1_1,null);
Button btnNext = (Button)rootView.findViewById(R.id.btnext);

btnNext.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v){
nextscreen();
}
});

return rootView;
//return inflater.inflate(R.layout.fragment1_1, null);
}

public void nextscreen(){
Intent nextScreen = new Intent(getActivity(), Fragment1_2.class);
startActivity(nextScreen);
}
}

I got this solution back but still not work ,Do Frament1_2 have to "extends Fragment" too?

To create a fragment, you must create a subclass of Fragment (or an existing subclass of it)

if a class "Fragment2" does not inherit from "Fragment", then it's just a pojo and nothing more.
