Webview does not reload

Webview does not reload - java

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.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?

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;
}

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.

If you need any other code snippets, please tell me (maybe the xml

Thanks

That is because you are returning 0 in the getItemCount method
Change this :
#Override
public int getItemCount() {
return 0;
}
To this:
#Override
public int getItemCount() {
return (mData != null ? mData.size():0);
}

you should set layout manager first
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.habits_frag, container, false);
recyclerView = root.findViewById(R.id.rv_list);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
recyclerView.setAdapter(mListAdapter);
return root;
}
also you need to change the getItemCount into
#Override
public int getItemCount() {
if(mData!=null){return mData.size();}else return 0;
}

The reason you are getting empty list because your method getItemCount returns 0.
Here is the modified method.
#Override
public int getItemCount() {
return mData!=null ? mData.size():0;
}

The progress bar and webview works fine but when the page is finished loading the progress bar still remains? When I have loaded the page the progress bar visibility doesn't dissapear/change to GONE? Where is the error?
Ive tried both progressBar.setVisibility(View.INVISIBLE) and progressBar.setVisibility(View.GONE); but nothin seems to work.

Instead of using customizing webclient. you use default webclient. your problem is replace this.
view.setWebViewClient(new WebViewClient());
add this
view.setWebViewClient(new MyAppWebViewClient());
and also
progressBar.setVisibility(View.INVISIBLE);
not
view.findViewById(R.id.progressBar1).setVisibility(View.GONE);

just changed WebViewClient to MyWebViewClient, progressBar to progressBar1 & ActionBarActivity to AppCompatActivity and every code seems to work :) thank again every1.. :) #Devendra & #akhil :)

After intent of webview url you have to write progressbar.visibility="View.GONE"

private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
progressBar.setVisibility(View.GONE);
FGallery.this.progressBar.setProgress(100);
super.onPageFinished(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progressBar.setVisibility(View.VISIBLE);
FGallery.this.progressBar.setProgress(0);
super.onPageStarted(view, url, favicon);
}
}
This is working for me. you can set it as WebViewClient.

How to prevent reload of Webview page

I have created an app in which i have 3 tabs to display webpages using fragment. Every time i switch to tab 2 from tab 1 and then back to tab 1, tab 1 reloads. I have searched google and solutions which i found didn't work. So far i have tried this:
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mWebView.saveState(outState);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
mWebView.restoreState(savedInstanceState);
}
And this:

One interesting thing is that whenever i use Tab1 and Tab2 non of them reloads but when i switch to Tab3 and then goes back to Tab1 then only it reloads.
Any Help would deeply appreciated.

Can you tried adding:
viewPager.setOffscreenPageLimit(2);
According to documentation, setOffscreenPageLimit is to:
Set the number of pages that should be retained to either side of the
current page in the view hierarchy in an idle state. Pages beyond this
limit will be recreated from the adapter when needed.
...
You should keep this limit low, especially if your pages have complex >layouts. This setting defaults to 1.
The default is 1 so when you go to tab 3 there are two tabs the the left of the current tab so tab 1 gets recreated.

How to use go back in sites correct?

I have my WebViewFragment and of course i want to go back in the site im browsing but i have the error:
The method onBackPressed() is undefined for the type Fragment
Why? I don´t understand that?
What am i doing wrong?
Here´s my full webview code i´m using.
import android.app.Fragment;
import android.content.Intent;
import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.DownloadListener;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebViewFragment extends Fragment {
WebView webView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Retrieving the currently selected item number
int position = getArguments().getInt("position");
String url = getArguments().getString("url");
// List of rivers
String[] menus = getResources().getStringArray(R.array.menus);
// Creating view corresponding to the fragment
View v = inflater.inflate(R.layout.fragment_layout, container, false);
// Updating the action bar title
getActivity().getActionBar().setTitle(menus[position]);
//Initializing and loading url in webview
webView = (WebView)v.findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadsImagesAutomatically(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.loadUrl(url);
webView.setWebChromeClient(new WebChromeClient());
webView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
view.loadUrl(url);
return true;
}
});
webView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent,
String contentDisposition, String mimetype,
long contentLength) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
startActivity(intent);
}
});
return v;
}
public void onBackPressed() {
if(webView.canGoBack()) {
webView.goBack();
} else {
super.onBackPressed();
}
}}
If i´m using:
public void onBackPressed() {
Fragment webview = getFragmentManager().findFragmentByTag("webview");
if (webview instanceof WebViewFragment) {
boolean goback = ((WebViewFragment)webview).canGoBack();
if (!goback)
super.onBackPressed();
}
}}
I have the errors:
The method canGoBack() is undefined for the type WebViewFragment
The method onBackPressed() is undefined for the type Fragment
Thank you dudes for your help!

Found the solution what is working for me in my fragment.
webView.setOnKeyListener(new 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 v;

OnLongClickListener - not getting fired + android

I have this OnLongClickListener which is not getting fired. I think I have setup everything correctly and it has worked with a contextmenu before but right now it's not firing and the log is not even giving me any error.
I really hope you can give me any ideas. It is probably a silly mistake somewhere.

Here is the xml file where I have my ListView:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/mainListView"
android:longClickable="true"
android:clickable="true"
></ListView>
</LinearLayout>

You are attaching a listener to the entire view instead of each row. I'm not sure why nothing is being fired, but those touch events are probably being intercepted by other views.
Instead of ListView.setOnLongClickListener(), you should use ListView.setOnItemLongClickListener().
Here is the link for the Android Docs for this method.

Since you are registerForContextMenu for your listview already. setOnLongClickListener is not longer needed. What you needs is onCreateContextMenu method and onContextItemSelected.
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo){
// create menu item here
}
#Override
public boolean onContextItemSelected(MenuItem item){
// do your long click listener here
}
