Accessing the TextView in a fragment throws a NullPointerException
I am new to android development.
I have TextView
in layout and when I try to access TextView
in class Fragment
a NullPointerException
. I am accessing the TextView like this:
TextView textView = (TextView) view.findViewById(R.id.quotes);
What am I doing wrong?
I've looked at other answers regarding this on SO but haven't found a solution ...
Corresponding code
quotes_details_fragment.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/quotes"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="@string/quotes_details"
android:textSize="24sp" />
</RelativeLayout>
QuotesFragment.java
public class QuotesFragment extends Fragment {
public QuotesFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.quotes_details_fragment, container, false);
TextView textView = (TextView) view.findViewById(R.id.quotes); // NullPointerException
return view;
}
}
(The main activity class only calls the corresponding fragment using FragmentTransaction
)
Thank you for your help.

add this LayoutInflater to your onCreateView (..);
LayoutInflater lf = getActivity().getLayoutInflater();
Same:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
LayoutInflater lf = getActivity().getLayoutInflater();
View view = lf.inflate(R.layout.quotes_details_fragment, container, false);
TextView textView = (TextView) view.findViewById(R.id.quotes); //
return view;
}
