Question

I have a WebViewFragment and when trying to get the webview to use, it gives me a null pointer

public class BallInfoFragment extends WebViewFragment {
long id;

public BallInfoFragment(long id){
    this.id = id;
}

@Override
public void onCreate(Bundle state){
    super.onCreate(state);
    String ball = new String();
    Cursor c = getActivity().getContentResolver().query(Balls.CONTENT_URI,new String[] {Balls.ID,Balls.BALL},Balls.ID+"="+id,null,null);
    c.moveToFirst();
    ball = c.getString(1);
    WebView wv = getWebView();  //getWebView always gives me null

why is it null?

Answer 1

You have to put the code within the onActivityCreated() function instead. This is called after the WebView has been instantiated.

@Override
public void onActivityCreated(Bundle savedInstanceState) { 
  // your code here.
  WebView wv = getWebView();
}

onCreate is called when the activity is created, before the WebView has been.
