I followed this guy's tutorial on how to make an ActionBar. Let's say I want to change the TextView inside one of the fragments. So I added this on my StartActivity.java, under onCreate: TextView textview = (TextView) findViewById(R.id.textView1); textview.setText("HI!"); When I start my app, it crashes. Can somebody point me to the right direction? I hope somebody takes the time to look at the guy's tutorial because his layout is basically the same as mine. Thank you. asked 23 mins ago

If you want change your component, I suggest you to make a method inside the fragment like this: 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; public class DetailFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.details, container, false); return view; } public void setText(String text){ TextView textView = (TextView) getView().findViewById(R.id.detailsText); textView.setText(text); } } answered 12 mins ago
