Webview does not reload

Question

I am using fragments and have added a item on the action bar to refresh webview named airport_menuRefresh but when ever i click it nothing happens. I have 3 tabs. I have tried different methods but neither of them works. Here is the code of my 1tab(tab1 only contains the not working logic to refresh).

import android.os.Bundle;
import android.os.Handler;
import android.support.v4.app.Fragment;    
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;

public class GamesFragment extends Fragment {

private ProgressBar progress;
private WebView myWebView;



public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    String url = "http://google.com";
    int delay = 6 * 1000;
    View rootView = inflater.inflate(R.layout.fragment_games, container, false);
    myWebView = (WebView)rootView.findViewById(R.id.webViewGames);
    myWebView.setWebChromeClient(new myWebViewClient());
    myWebView.getSettings().setJavaScriptEnabled(true);
    progress = (ProgressBar)rootView.findViewById(R.id.progressBar);
    progress.setMax(100);

    Handler handler = new Handler();
    MyRunnable runnable = new MyRunnable(url, myWebView);
    handler.postDelayed(runnable, delay);

    myWebView.setWebViewClient(new WebViewClient() {

        @Override
        public boolean shouldOverrideUrlLoading(WebView View, String url) {
            GamesFragment.this.progress.setProgress(0);
            View.loadUrl(url);
            return true;
        }



    });



    myWebView.setOnKeyListener(new android.view.View.OnKeyListener() {
        @Override
         public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (event.getAction() == KeyEvent.ACTION_DOWN) {
            WebView webView = (WebView) v;

            switch (keyCode) {
                case KeyEvent.KEYCODE_BACK:
                    if (webView.canGoBack()) {
                        webView.goBack();
                        return true;
                    }
                    break;
            }
        }
        return false;
        }
    });



   return rootView;

}



@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {
           case R.id.airport_menuRefresh:
            GamesFragment.this.myWebView.loadUrl("http://google.com");
            return true;
    }
    return super.onOptionsItemSelected(item);
}




public class MyRunnable implements Runnable {

     String url;
    private WebView mywebview;

    public MyRunnable(String url, WebView wv) {
        this.url = url;

        this.mywebview = wv;
    }

    public void run() {

        mywebview.loadUrl(url);

    }
}



private class myWebViewClient extends WebChromeClient {
    @Override
    public void onProgressChanged(WebView view, int newProgress) {
        GamesFragment.this.setValue(newProgress);
        super.onProgressChanged(view, newProgress);
    }
}




public void setValue(int progress) {
    this.progress.setProgress(progress);
}


}

Here is my main Activity:

 import android.annotation.TargetApi;
 import android.os.Build;
 import android.os.Bundle;
 import android.support.v4.view.ViewPager;
 import android.support.v7.app.ActionBarActivity;
 import android.support.v7.widget.Toolbar;
 import android.view.Menu;
 import android.view.MenuInflater;
 import android.view.MenuItem;

 import com.tech.example.adaptor.SlidingTabLayout;
 import com.tech.example.adaptor.TabsPagerAdapter;

 @TargetApi(Build.VERSION_CODES.HONEYCOMB)
 public class MainActivity extends ActionBarActivity {
 SlidingTabLayout tabs;
 ViewPager viewPager;
 TabsPagerAdapter adapter;
 Toolbar toolbar;
 private Menu optionsMenu;

CharSequence Titles[]={ "tab1", "tab2", "tab3" };
int Numboftabs =3;

@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

     toolbar = (Toolbar) findViewById(R.id.tool_bar);
    setSupportActionBar(toolbar);

    adapter = new TabsPagerAdapter(getSupportFragmentManager(), Titles, Numboftabs);
    // Assigning ViewPager View and setting the adapter
    viewPager = (ViewPager) findViewById(R.id.pager);
    viewPager.setAdapter(adapter);
    viewPager.setOffscreenPageLimit(2);
    // Assiging the Sliding Tab Layout View
    tabs = (SlidingTabLayout) findViewById(R.id.tabs);
    tabs.setDistributeEvenly(true);
    setRefreshActionButtonState(true);
    tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
        @Override
        public int getIndicatorColor(int position) {
            return getResources().getColor(R.color.tabsScrollColor);
        }

        @Override
        public int getDividerColor(int i) {
            return 0;
        }
    });

    tabs.setViewPager(viewPager);
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    this.optionsMenu = menu;
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_main, menu);
    return true;
}


public void setRefreshActionButtonState(final boolean refreshing) {
    if (optionsMenu != null) {
        final MenuItem refreshItem = optionsMenu
                .findItem(R.id.airport_menuRefresh);
        if (refreshItem != null) {
            if (refreshing) {
                refreshItem.setActionView(R.layout.actionbar_indeterminate_progress);
            } else {
                refreshItem.setActionView(null);
            }
        }
    }
}

}

EDIT

I edited my main activity like this:

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {
        case R.id.airport_menuRefresh:

            GamesFragment.myWebView1.loadUrl("http://example.com");

            MoviesFragment.myWebView.loadUrl("http://example2.com");

            TopRatedFragment.myWebView2.loadUrl("http://example3.com");
            return true;
    }
    return super.onOptionsItemSelected(item);
    }

Now its reloading but suppose i click reload on tab1 all 3 tabs reloads! Any solution?

You can do one thing to prevent that you can check which fragment you are currently in and base on that you can reload your webview. Do you have 3 fragments there? — BBdev, Apr 21 '15 at 12:07
You can go to this http://stackoverflow.com/questions/9294603/get-currently-displayed-fragment — BBdev, Apr 21 '15 at 12:09
What is the reason for when I put onitemselect in main activity then it works but when I put it in any of the 3 fragments it doesn't work. — Rahul, Apr 21 '15 at 18:51

I guess error is in the name of the WebView of your methods. As long as you imported:

import android.view.View;

When in this methow

public boolean shouldOverrideUrlLoading(WebView View, String url) {
//                                              ^-----> UPPERCASE

you make this call:

View.loadUrl(url);

you're trying to call static method of View and not the instance of View from method signature.

try this:

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
//                                              ^---> lowercase
    GamesFragment.this.progress.setProgress(0);
    view.loadUrl(url);
//  ^---> lowercase
    return true;
}

That cannot be the reason because by your suggestion `View` don't have `loadUrl()` method. – BBdev Apr 21 '15 at 10:40
And in this case `View.loadUrl()` means its the instace of `WebView` – BBdev Apr 21 '15 at 10:43

Finally i found a solution.

Moved onCreateOptionsMenu and onOptionsItemSelected from main activity to fragment tabs like this

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
   .............
  .............
 .............
setHasOptionsMenu(true);
.................
.................
 }


@Override
public void onCreateOptionsMenu(
        Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.menu_main, menu);
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // handle item selection
    switch (item.getItemId()) {
        case R.id.airport_menuRefresh:

              TopRatedFragment.this.myWebView2.loadUrl("http://myexample.com");
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

And this worked like a charm.
