i am trying to make a app for android in eclipse. where i different fragments with webviews in it. but i want to show a progress bar when webview in loading but i could not getting it how to do it i checked many tutorials but failed to do so. let me most activity code here.
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MenuInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.app.Fragment;
import android.annotation.SuppressLint;
//import android.graphics.Bitmap;
//import android.widget.ProgressBar;
//import android.app.ProgressDialog;
//import android.app.Activity;
#SuppressLint("SetJavaScriptEnabled")
public class AdminTab1 extends Fragment {
private WebView webView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setHasOptionsMenu(true);
View rootView = inflater.inflate(R.layout.admintab1, container, false);
webView = (WebView) rootView.findViewById(R.id.webView1);
webView.setWebViewClient(new WebViewClient());
webView.setScrollbarFadingEnabled(false);
webView.setHorizontalScrollBarEnabled(false);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setUserAgentString("AndroidWebView");
webView.clearCache(true);
webView.loadUrl("http://ww.google.com");
return rootView;
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.mainmenu, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.item1:
webView.reload();
break;
case R.id.item2:
webView.goBack();
break;
default:
break;
}
return true;
}
}
You should try this
public class About27Fragment extends Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View rootView = inflater.inflate(R.layout.about_27, container, false);
final WebView webView = (WebView) rootView.findViewById(R.id.webView_about27);
final ProgressDialog dialog = ProgressDialog.show(getActivity(), "", "Please wait, Loading Page...", true);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon){
dialog.show();
}
#Override
public void onPageFinished(WebView view, String url){
dialog.dismiss();
String webUrl = webView.getUrl();
}
});
webView.loadUrl("https://www.google.com.mx");
return rootView;
}
}
WebViewClient has a lot of callback. You should subclass it and override onPageStarted to show and onPageFinished to dismiss it, for instance. Take a look to the doc, here
private class MyWebClient extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url,
// here show the dialog
}
public void onPageFinished(WebView view, String url) {
// here dismiss it
}
}
and in onCreateView use it like
webView.setWebViewClient(new MyWebClient());
oncreate
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.web_view);
web_view = (WebView) findViewById(R.id.web_view);
pd = new ProgressDialog(Activity.this);
pd.setMessage("Please wait Loading...");
pd.show();
web_view.setWebViewClient(new MyWebViewClient());
web_view.loadUrl("ur site name");
}
WebViewClient
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
if (!pd.isShowing()) {
pd.show();
}
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
System.out.println("on finish");
if (pd.isShowing()) {
pd.dismiss();
}
}
In this way you can implement Progress Dialog in webview.
Try this to get progress in percentage
myWebView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// Activities and WebViews measure progress with different
// scales
//Updaate progress bar here with progress int
}
});

I'm building my own browser using android studio. I need to block specific websites in the browser e.g facebook.com, youtube.com. How can I do that.
package com.example.privatebrowser;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends AppCompatActivity {
private WebView pb;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pb = (WebView) findViewById(R.id.privatebrowser);
pb.setWebViewClient(new WebViewClient());
pb.loadUrl("https://www.google.com/");
WebSettings webSettings = pb.getSettings();
webSettings.setJavaScriptEnabled(true);
}
#Override
public void onBackPressed(){
if(pb.canGoBack()){
pb.goBack();
}
else
{
super.onBackPressed();
}
}
}
Create a custom WebView client
private class MyWebViewClient extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
String url = request.getUrl().toString();
//Log.e("url", URL);
if(url.contains("url you want to block") {
//do whatever you want to do
} else {
view.loadUrl(url);
}
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
}
}
Then set above WebClient in your WebView
pb.setWebViewClient(new MyWebViewClient());
I am stuck at the last phase of my project. I am developing a android webview app in which user can share the current loaded page in there social apps. My share button is in the top at the toolbar. Currently I am able to share the loaded url through the share button but when I jump to a new page and press share button, still initial loaded url is shared. Here I need to share the current url from the toolbar menu.
Please help

You should set WebViewClient with your webview like below:
WebView webview = new WebView(context);
webview.setWebViewClient(new WebViewClient()
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
Log.d("WebView", "your current url when webpage loading.." + url);
}
#Override
public void onPageFinished(WebView view, String url) {
Log.d("WebView", "your current url when webpage loading.. finish" + url);
super.onPageFinished(view, url);
}
#Override
public void onLoadResource(WebView view, String url) {
// TODO Auto-generated method stub
super.onLoadResource(view, url);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
System.out.println("when you click on any interlink on webview that time you got url :-" + url);
return super.shouldOverrideUrlLoading(view, url);
}
});
You can get current loaded url from shouldOverrideUrlLoading() .
Can anyone please help me check my code to see why it cannot be
launched in the app itself but directs me to a browser? ): Thanks!!

return true;
}
}
Where is the error? :D
It keeps opening up in the browser.
In the following line:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
you're asking Android to open a URL using the intent constant ACTION_VIEW - so it defaults to the external browser.
Here a full example (taken from here) that shows how to open the url using a WebViewClient:
package com.paresh.webviewclientdemo;
import android.app.Activity;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
/*
* Demo of creating an application to open any URL inside the application and clicking on any link from that URl
should not open Native browser but that URL should open in the same screen.
*/
public class WebViewClientDemoActivity extends Activity {
/** Called when the activity is first created. */
WebView web;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
web = (WebView) findViewById(R.id.webview01);
web.setWebViewClient(new myWebClient());
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("http://www.google.com");
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
}
// To handle "Back" key press event for WebView to go back to previous screen.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if ((keyCode == KeyEvent.KEYCODE_BACK) && web.canGoBack()) {
web.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
I am trying to hide my fragment when its not on the screen so i used setUserVisibleHint to hide my fragment but i am getting an error
"myUIUpdate (View) in GamesFragment cannot be applied to ()"
How do i resolve it?
Here is my activity:
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.KeyEvent;
import android.view.LayoutInflater;
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;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_games, null);
return rootView;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
myUIUpdate(view);
}
void myUIUpdate(View view) {
String url = "http://gsmarena.com";
myWebView = (WebView)this.getView().findViewById(R.id.webViewGames);
myWebView.setWebChromeClient(new myWebViewClient());
myWebView.getSettings().setJavaScriptEnabled(true);
progress = (ProgressBar) this.getView().findViewById(R.id.progressBar);
myWebView.loadUrl(url);
progress.setMax(100);
myWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView View, String url) {
View.loadUrl(url);
GamesFragment.this.progress.setProgress(0);
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;
}
});
}
private class myWebViewClient extends WebChromeClient {
#Override
public void onProgressChanged(WebView view, int newProgress) {
GamesFragment.this.setValue(newProgress);
super.onProgressChanged(view, newProgress);
}
}
boolean isResumed = false;
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser); {
if (isVisibleToUser && isResumed()) {
myUIUpdate();
isResumed = true;
}
}}
public void setValue(int progress) {
this.progress.setProgress(progress);
}
}
To be precise error comes in this line:
boolean isResumed = false;
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser); {
if (isVisibleToUser && isResumed()) {
// here is the error.
myUIUpdate();
isResumed = true;
}
}}
I have tried changing
myUIUpdate();
to
myUIUpdate(View);
When i try to do that it says"expression expected".
If you want to get to Fragment's View you can use Fragment.getView() and pass it to your myUiUpdate
I am building one app for my online radio station with iframe the site. But how I will add a progress status or animation image so that it's start on loading & end after load the site ? Here is the code I am using now:

webview.getSettings().setUseWideViewPort(true);
webview.getSettings().setAllowUniversalAccessFromFileURLs(true);
webview.loadUrl("http://hoicoimasti.com/radio/");
}
}
I also have another problem. When I select one country from drop down menu showing inside the app it's open different browser. How do I stop that & open inside the app ? Thanks in advance.
Just did it :) & solved other problem also :)
