Passer des données entre les fragments dans Android à l'aide de l'interface
public class FragmentA extends Fragment
{
DataPassListener mCallback;
public interface DataPassListener{
public void passData(String data);
}
@Override
public void onAttach(Context context)
{
super.onAttach(context);
// This makes sure that the host activity has implemented the callback interface
// If not, it throws an exception
try
{
mCallback = (OnImageClickListener) context;
}
catch (ClassCastException e)
{
throw new ClassCastException(context.toString()+ " must implement OnImageClickListener");
}
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState)
{
// Suppose that when a button clicked second FragmentB will be inflated
// some data on FragmentA will pass FragmentB
// Button passDataButton = (Button).........
passDataButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (view.getId() == R.id.passDataButton) {
mCallback.passData("Text to pass FragmentB");
}
}
});
}
}
