Can not resolve method 'findViewById(int)'

Question

I'm having a trouble with findViewByid but I can't find where the problem is.

Here's my FirstFragment class code:

import android.app.Fragment; import android.os.Bundle; import android.support.annotation.Nullable; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.webkit.WebSettings; import android.webkit.WebView; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.ProgressBar;  import java.util.ArrayList; import java.util.List;   public class FirstFragment extends Fragment { public static final String TAG = "first";  private WebView mWebView; ProgressBar progressBar;   @Override public void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);       mWebView = (WebView) findViewById(R.id.activity_main_webview);      progressBar = (ProgressBar) findViewById(R.id.progressBar1);      WebSettings webSettings = mWebView.getSettings();     webSettings.setJavaScriptEnabled(true);     mWebView.loadUrl("http://www.google.com");  }  @Nullable @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {     return inflater.inflate(R.layout.secondefragment, container, false); }  @Override public void onActivityCreated(Bundle savedInstanceState) {     super.onActivityCreated(savedInstanceState);    } } 

Answer 1

You need to do this in onCreateView:

@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle   savedInstanceState) {    View view =  inflater.inflate(R.layout.secondefragment, container, false);     mWebView = (WebView) view.findViewById(R.id.activity_main_webview);    progressBar = (ProgressBar) view.findViewById(R.id.progressBar1);     WebSettings webSettings = mWebView.getSettings();    webSettings.setJavaScriptEnabled(true);    mWebView.loadUrl("http://www.google.com");     return view;   } 

Answer 2

Fragment doesn't provide thefindViewById() method. This is provided in Activity or View. When implementing a Fragment you don't inflate your views in onCreate() (like you normally do in an Activity.) Instead, you do it in onCreateView() and you need to use the inflated root View to find the ID within the layout you inflated.
