Their is class cast exception you are casting Fragment to activity.

I am not able to figure out which line it is but you can do go on Logcat and click on this line.

Caused by: java.lang.ClassCastException: com.ebspma.activity.ReservasSalasFragment cannot be cast to android.app.Activity

this will take you to exact line where is error then post that line then we can figure out.


Reply if you not found your solution

Hi

I did use the logcat but in that error i don't have any line error so i don't know where is the problem

any help?

[Ulf Dittmer]

What are you doing in the app when this happens? How are you using this class?

[Gil Carvalho]

Hi

I'm pressing a button to move to my next class

Im moving from this class:

public class ReservasFragment extends Fragment {
	public ReservasFragment() {
	}

	ImageButton salas;
	ImageButton equip;

	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
		View rootView = inflater.inflate(R.layout.fragment_reservas, container,false);
		salas = (ImageButton) rootView.findViewById(R.id.salas);
		equip = (ImageButton) rootView.findViewById(R.id.equipamentos);
		
		
		salas.setOnClickListener(new View.OnClickListener() {
			@Override
			public void onClick(View v) {
				Intent intent = new Intent(getActivity(),ReservasSalasFragment.class);
				startActivity(intent);
			}
		});
		
		equip.setOnClickListener(new View.OnClickListener() {

			@Override
			public void onClick(View v) {
				Intent intent = new Intent(getActivity(),ReservasSalasFragment.class);
				startActivity(intent);
			}
		});
		return rootView;
	}

}

And i have that error as soon i click the button to move to another class

regards

[Ulf Dittmer]

Right: Context.startActivity starts an activity (no surprise there :-), so the Intent needs an Activity, not a Fragment,.

[Gil Carvalho]

Ok, thank you

So i do i call the fragment in this case??

regards

[Ulf Dittmer]

You'd replace the current layout with the new Fragment in a fragment transaction. See http://developer.android.com/training/basics/fragments/creating.html for an example of how to handle multiple fragments, both for the phone (one fragment) and tablet (two fragments) cases.
