Wont find R.Id. in fragment


I'm trying to get a text view to link to a site, but it won't find the id from xml in android. Any help would be great. Here's the code

It wont find the R.id.textviewlink

public class Fragment_2 extends Fragment{
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){

        return inflater.inflate(R.layout.fragment_2, null);

        TextView t2 = (TextView) getView().findViewById(R.id.textviewlink);
        t2.setMovementMethod(LinkMovementMethod.getInstance());
    }
}

XML

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingTop="10dip"
android:paddingLeft="10dip"
android:paddingRight="10dip" 
android:background="@drawable/backgroundw">

<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

            <TextView
    android:id="@+id/textviewlink"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:text="Free PDF Download"
    android:linksClickable="true"/>

    </LinearLayout>
    </ScrollView>
    </RelativeLayout>

Solution

  • That is because you have already returned your inflated layout before finding the view item. There are two options.

    First, the inflate() method always requires three arguments:

    inflater.inflate(R.layout.file_name, container, false);
    

    Put the following in onStart:

    TextView t2 = (TextView) getView().findViewById(R.id.textviewlink);
    t2.setMovementMethod(LinkMovementMethod.getInstance());
    

    Or just use this:

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
       View v = inflater.inflate(R.layout.fragment_2, container, false); //don't forget the third argument here
       TextView t2 = (TextView) v.findViewById(R.id.textviewlink);
       t2.setMovementMethod(LinkMovementMethod.getInstance());
    
       return v;
     }
