Anyone can take a look at my code and let me know what I am missing?
MainActivity.java:
public class MainActivity extends AppCompatActivity {
private WebView mWebView;
private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener
= new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.navigation_home:
mWebView.loadUrl("https://yahoo.com");
return true;
case R.id.navigation_dashboard:
mWebView.loadUrl("https://google.com");
return true;
case R.id.navigation_notifications:
mWebView.loadUrl("https://apple.com");
return true;
}
return false;
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BottomNavigationView navView = findViewById(R.id.nav_view);
mWebView = (WebView) findViewById(R.id.webkit);
navView.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
WebSettings webSettings = mWebView.getSettings();
webSettings.setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
webSettings.setDomStorageEnabled(true);
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
mWebView.loadUrl("https://google.com");
return true;
}
});
}
}

Replace
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
mWebView.loadUrl("https://google.com");
return true;
}
});
With
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
return false;
}
});
Give the host application a chance to take control when a URL is about
to be loaded in the current WebView. If a WebViewClient is not
provided, by default WebView will ask Activity Manager to choose the
proper handler for the URL. If a WebViewClient is provided, returning
true causes the current WebView to abort loading the URL, while
returning false causes the WebView to continue loading the URL as
usual.
So far from what I can tell you are supposed to extend the WebViewClient class with a separate class:
private class MyBrowser extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
and then set it to the WebViewClient:
mWebView.setWebViewClient(new MyBrowser());
Also try adding settings for loading images automatically, enabling javascript and setting scrollbar:
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
mWebView.getSettings().setLoadsImagesAutomatically(true);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
case R.id.navigation_home:
mWebView.loadUrl("https://yahoo.com");
return true;
case R.id.navigation_dashboard:
mWebView.loadUrl("https://google.com");
return true;
case R.id.navigation_notifications:
mWebView.loadUrl("https://apple.com");
return true;
}
return false;
}
if you are using android 8+ then you must have to do 2 things.
Add this android:usesCleartextTraffic="true" attribute in manifest application tag. AndroidManifest.xml
you should override this method.
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
view.load(request.getUrl().toString())
return true;
}
});
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
mWebView.loadUrl("https://facebook.com");
return true;
}
});

I am loading a web URL in webview. Like below :-
mWebView = (WebView)findViewById(R.id.id__web_view);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient());
mWebView.loadUrl("http://www.google.com");
How can I detect a button click event inside the loaded page. Say for example I want to show a toast "Clicked" when user clicks on "Images" tab after the search is done.(Please note that the detection of button click is one page ahead of the page that I loaded).
What I have tried:-
I did some research on how to do this, but none of these were fruitfull.
Below is one among them :-
WebSettings ws = wv.getSettings();
ws.setJavaScriptEnabled(true);
wv.addJavascriptInterface(new Object()
{
public void performClick()
{
// Deal with a click on the OK button
}
}, "ok");
<button type="button" onclick="ok.performClick();">OK</button>
But this requires adding onclick in the html, I am not sure is it possible to do it on a 3rd party website. Please throw some light into the problem if any one has any clue.
Checkout below code.. its working fine for me
#SuppressLint("SetJavaScriptEnabled")
public class MainActivity extends Activity {
private WebView mWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView)findViewById(R.id.webView1);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setLoadsImagesAutomatically(true);
mWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
mWebView.setWebViewClient(new MyBrowser());
mWebView.loadUrl("file:///android_asset/index.html");
}
private class myWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
view.addJavascriptInterface(new Object()
{
#JavascriptInterface
public void performClick() throws Exception
{
Log.d("LOGIN::", "Clicked");
Toast.makeText(MainActivity.this, "Login clicked", Toast.LENGTH_LONG).show();
}
}, "login");
return true;
}
}
#Override

I have written sample webview code by looking at examples found from internet. I want to show progressbar till webview loads a page in my fragment.
My activity contains toolbar, frame that shows fragments and navigation drawer. When i select an entry from navigation drawer, new fragment is shown which contains progress bar and webview and the fragment simply tries to load the page below is the code for fragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_full_page, container, false);
//int view_num = getArguments().getInt(ARG_SECTION_NUMBER);
progressBar = (ProgressBar)rootView.findViewById(R.id.webviewProgress);
progressBar.setVisibility(View.VISIBLE);
webView = (WebView) rootView.findViewById(R.id.webView1);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setAppCacheEnabled( true );
webView.getSettings().setUseWideViewPort(true);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setScrollbarFadingEnabled(true);
//webView.getSettings().setSupportZoom(true);
webView.getSettings().setCacheMode( WebSettings.LOAD_DEFAULT );
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
String urlString = getArguments().getString("URLSTRING");
final Boolean clickable = getArguments().getBoolean("CLICKABLE");
Boolean networkAvailable = Utils.isNetworkAvailable(super.getActivity().getApplicationContext());
if(networkAvailable == true) {
webView.loadUrl(urlString);
} else {
webView.loadUrl(Utils.DEFAULT_URL_PAGE);
}
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
//progressBar.setVisibility(View.VISIBLE);
if (clickable) {
view.loadUrl(url);
return false;
} else {
return true;
}
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
progressBar.setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
}
});
webView.setOnKeyListener(new 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;
}
Below is fragment_full_page.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".FragmentFullPage" >
<ProgressBar
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="center|top"
android:id="#+id/webviewProgress"
/>
<WebView
android:id="#+id/webView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
web page is taking time to load (tried with wifi and 3g) but progress bar is not showing any time.
To test if progressbar actually shows in the middle of the fragment_full_page, I removed webview code and just kept progress bar then it is showing.
made something wrong with the code that is not showing progress bar while webview is loading which i am unable to figure out.
I am trying to add a progressbar to a webview class.However, even after following all steps correctly, it crashes with a null pointer exception, any idea why?
Here's my mainactivity:
public class MainActivity extends Activity {
WebView webview;
ProgressBar progress;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
// getWindow().requestFeature(Window.FEATURE_PROGRESS);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
webview = (WebView)findViewById(R.id.webview);
webview.setInitialScale(1);
WebSettings webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);
progress = (ProgressBar) webview.findViewById(R.id.ProgressBar);
progress.setVisibility(View.VISIBLE);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setLoadWithOverviewMode(true);
webview.getSettings().setUseWideViewPort(true);
// webview.setWebViewClient(new MyCustomWebViewClient());
webview.setScrollBarStyle(View.SCROLLBARS_OUTSIDE_OVERLAY);
webview.setScrollbarFadingEnabled(false);
webview.getSettings().setRenderPriority(RenderPriority.HIGH);
webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
// webview.getSettings().setBlockNetworkLoads(true);
webview.getSettings().setBuiltInZoomControls(true);
webview.loadUrl("http://www.yahoo.com");
webview.getSettings().setSupportZoom(false);
/* webview.setWebChromeClient(new WebChromeClient()
{
public void onProgressChanged(WebView view, int progress)
{
// update the progressBar
MainActivity.this.setProgress(progress * 100);
}
});*/
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if(event.getAction() == KeyEvent.ACTION_DOWN){
switch(keyCode)
{
case KeyEvent.KEYCODE_BACK:
if(webview.canGoBack() == true){
webview.goBack();
}else{
finish();
}
return true;
}
}
return super.onKeyDown(keyCode, event);
}
private class MyCustomWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progress.setVisibility(View.VISIBLE);
}
public void onPageFinished(WebView view, String url) {
progress.setVisibility(View.GONE);
}
}
}
and here's the corresponding xml:
main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<ProgressBar
android:id="#+id/ProgressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:maxHeight="30dp"
android:minHeight="30dp" />
</RelativeLayout>
Change
progress = (ProgressBar) webview.findViewById(R.id.ProgressBar);
to
progress = (ProgressBar)findViewById(R.id.ProgressBar);
Progressbar belongs to main.xml. findViewById looks for a view in the current inflated layout. You have set the content of layout main.xml to your activity.
I see that you copied an example, but you did it wrong. Replace the commented code with this:
webView.setWebChromeClient(new WebChromeClient()
{
public void onProgressChanged(WebView view, int prog)
{
progress.setProgress(prog * 100);
}
});
Also, as said in the other post, that webview in webview.findViewById needs to be removed.
YouTube Video not playing in WebView.
It my first app ,I Want to do a webview.
When I open YouTube the video not playing, is loading but not playing.
Is loading all the time.

Seems like duplicate of play youtube video in WebView and YouTube Video not playing in WebView - Android
To make it work via WebView, I used the following two steps (version 4.2.2/Nexus 4):
On shouldOverrideUrlLoading I added webview.setWebChromeClient(new WebChromeClient());
In AndroidManifest.xml for activity tag I added android:hardwareAccelerated="true"
AndroidManifest.xml should also contain Internet permission.
While exact steps with playing video via WebView can be specific to device and Android version, there are also other alternatives to WebView, like VideoView or using Youtube Android Player API.
EDIT1
As for pause and full screen, this is actually a second link I mentioned in the beginning. To make it easier, I am posting code that worked on my Nexus.

Adding webchrome client solves the issue,
web = (WebView) vi.findViewById(R.id.offer_webView1);
web.loadUrl(getResources().getString(R.string.videolink));
web.getSettings().setJavaScriptEnabled(true);
// web.getSettings().setDomStorageEnabled(true);
web.getSettings().setAllowContentAccess(true);
WebSettings webSettings = web.getSettings();
webSettings.setPluginState(WebSettings.PluginState.ON);
webSettings.setUseWideViewPort(true);
webSettings.setLoadWithOverviewMode(true);
web.canGoBack();
web.setWebChromeClient(new WebChromeClient() {});
Hello i have a weird thing here, i have a list of items and i want when i click on any item, it will open an WebView which looks like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" android:theme="#android:style/Theme.Dialog">
<WebView android:id="#+id/BrowserView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="fitXY" />
here is the code i invoke the WebView
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long arg) {
setContentView(R.layout.external_view);
// load url or html
RssItem listItem = (RssItem) listView.getItemAtPosition(position);
webView = (WebView) findViewById(R.id.BrowserView);
// set browser settings
webView.setWebViewClient(new ExternalWebViewClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setPluginsEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(false);
webView.setInitialScale(1);
try {
webView.loadUrl(listItem.getExternalUrl());
} catch (Exception ex) {
Log.d("WEBVIEW", ex.getMessage());
}
}
});
Here is the "ExternalWebViewClient" class
public class ExternalWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
view.clearHistory();
}
}
Now the question:
How do i close it and stay in the same activity after i press the "back" button,
here is my back button handling code:
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
if (webView.canGoBack() == true) {
webView.goBack();
} else {
//what should i do here?????????????????
return true;
}
}
}
return false;
}
Basically, you should not need to handle Back button yourself. If you are in the WebView and press Back - you should be taken to your last activity by default.
