23,937 PointsNavigation Drawer crashing
I have a navigation drawer and I'm using Android Studio and the NavigationDrawerFragment. Been able to setup my Navigation drawer to call other fragments into view. However now I'm unable to call an intent within a fragment
``import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView;
// A placeholder fragment containing a simple view.
public class LoginActivity extends Fragment {
//The fragment argument representing the section number for this
//fragment.
private static final String ARG_SECTION_NUMBER = "section_number";
public static final String TAG = LoginActivity.class.getSimpleName();
Context mContext;
protected TextView mSignUpTextView;
// Returns a new instance of this fragment for the given section
//number.
public static LoginActivity newInstance(int sectionNumber) {
LoginActivity fragment = new LoginActivity();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
public LoginActivity() {
mSignUpTextView = (TextView)getActivity().findViewById(R.id.signUpText);
mSignUpTextView.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
Intent intent = new Intent(getActivity(), SignUpActivity.class);
startActivity(intent);
}
});
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.activity_login, container, false);
mContext = rootView.getContext();
return rootView;
}
}``
There is my fragment code. Anything I might be doing wrong?
