When I make a video full screen in WebView, the toolbar is not hidden. How can I hide it? Below you can see the codes I use.I'm using fragment and the navigation drawer menu.

I would recommend you to try out the follow code and remove the listeners which are related to loading the contents of your WebView.
You need to implement the method to load the website in your webview first.
private void loadWebsite() {
ConnectivityManager connectivityManager = (ConnectivityManager) getApplication().getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivityManager .getActiveNetworkInfo();
if (networkInfo != null && networkInfo.isConnectedOrConnecting()) {
mWebView.loadUrl("yourURL");
} else {
mWebView.setVisibility(View.GONE);
}
}
From here, you need to implement 2 different class "Browser_Home" and "MyChrome". For testing purposes, just write it outside searchWebFragment and later on you can implement it as a separate java file. With only the Browser_Home class, the fullscreen button will be disabled. When MyChrome class is added, fullscreen button is enabled and toolbar should disappear as intended.
class Browser_home extends WebViewClient {
Browser_home() {
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public void onPageFinished(WebView view, String url) {
setTitle(view.getTitle());
progressBar.setVisibility(View.GONE);
super.onPageFinished(view, url);
}
}
private class MyChrome extends WebChromeClient {
private View mCustomView;
private WebChromeClient.CustomViewCallback mCustomViewCallback;
protected FrameLayout mFullscreenContainer;
private int mOriginalOrientation;
private int mOriginalSystemUiVisibility;
MyChrome() {}
public Bitmap getDefaultVideoPoster()
{
if (mCustomView == null) {
return null;
}
return BitmapFactory.decodeResource(getApplicationContext().getResources(), 2130837573);
}
public void onHideCustomView()
{
((FrameLayout)getWindow().getDecorView()).removeView(this.mCustomView);
this.mCustomView = null;
getWindow().getDecorView().setSystemUiVisibility(this.mOriginalSystemUiVisibility);
setRequestedOrientation(this.mOriginalOrientation);
this.mCustomViewCallback.onCustomViewHidden();
this.mCustomViewCallback = null;
}
public void onShowCustomView(View paramView, WebChromeClient.CustomViewCallback paramCustomViewCallback)
{
if (this.mCustomView != null)
{
onHideCustomView();
return;
}
this.mCustomView = paramView;
this.mOriginalSystemUiVisibility = getWindow().getDecorView().getSystemUiVisibility();
this.mOriginalOrientation = getRequestedOrientation();
this.mCustomViewCallback = paramCustomViewCallback;
((FrameLayout)getWindow().getDecorView()).addView(this.mCustomView, new FrameLayout.LayoutParams(-1, -1));
getWindow().getDecorView().setSystemUiVisibility(3846);
}
}
And finally, apply the following functions and attributes to your webview and give it another try. Remember to apply these within your OnCreate method:
mWebView.setWebViewClient(new Browser_home());
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setAllowFileAccess(true);
webSettings.setAppCacheEnabled(true);
loadWebsite();
Let me know if this works and I can credit the corresponding person for the assistance with the code and classes.
create a folder row and copy the video on raw folder on resources and do the following steps,
On your XML file add VideoView,
<VideoView
android:id="#+id/vdoPlayer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"/>
On your .java class file do,
Uri uri = Uri.parse("android.resource://Your package name Here/" + R.raw.welcome_video);
vdoPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setLooping(true);
}
});
vdoPlayer.setVideoURI(uri);
vdoPlayer.start();

You have to decode HTML:
URL yahoo = new URL("http://www.yahoo.com/");
BufferedReader in = new BufferedReader(
new InputStreamReader(
yahoo.openStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
After that get Image Tag from it then you can get mages from it and write to sd card.

You did not implement webview download listener,please refer to the following code :
public class MainActivity : Activity
{

protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
wv1 = FindViewById<WebView>(Resource.Id.webView1);
wv1.SetDownloadListener(new MyDownloadListerner(this));
wv1.LoadUrl("https://notepad-plus-plus.org/download/v7.3.2.html");
}
class MyDownloadListerner : Java.Lang.Object, IDownloadListener
{
Context cont;
public MyDownloadListerner(Context context)
{
cont = context;
}
public void OnDownloadStart(string url, string userAgent, string contentDisposition, string mimetype, long contentLength)
{
Android.Net.Uri uri = Android.Net.Uri.Parse(url);
Intent intent = new Intent(Intent.ActionView,uri);
cont.StartActivity(intent);
}
}
}
Note: This method is start another browser to download, you can also create a new thread to download file at the OnDownloadStart function.

the webpage have some popup ads is there any way to prevent the popup from loading when the popup loads the main site doesnt appears is there any way to load the main page with out popups and how can i add a download handler l mean the webview should support downloading .torrent file

}
#Override

}
});
if(isOnline()) {
webView.loadUrl("http://testsite.com/");
} else {
String summary = "<html><body><font color='red'>No Internet Connection</font></body></html>";
webView.loadData(summary, "text/html", null);
toast("No Internet Connection.");
}
}
private void toast(String message) {
Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}
public void onBackPressed() {
if(webView.canGoBack()) {
webView.goBack();
} else {
super.onBackPressed();
}
}
private boolean isOnline() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
return (netInfo != null && netInfo.isConnected());
}
public void but(View v){
webView.loadUrl("http://testsite.com/");
}
}
if the url changes then use shouldOverrideUrlLoading with some regex
so
List<String> validUrls = new LinkedList<>();
validUrls.add("https://www\\.google\\.com/*");
validUrls.add("https://www\\.facebook\\.com/*");
#Override public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (isValidUrl(url)) {
return false;
}
return true;
}
private boolean isValidUrl(String url) {
for (String validUrl : validUrls) {
Pattern pattern = Pattern.compile(validUrl, Pattern.MULTILINE);
Matcher matcher = pattern.matcher(url);
if (matcher.find()) {
return true;
}
}
return false;
}
would match against any www.google.com or facebook.com urls
You can intercept the urls that are opened from the webview, I don't know if it would work with the popup:
WebViewClient client= new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
if (url.equals("popupURL"){
return true;
}
return false;
}
}
webView.setWebViewClient(client);
I got a progress bar, a Full screen video playback method (for playing youtube videos in full-screen), and public boolean shouldOverrideUrlLoading for handling URL's within the WebView but i cannot get all of the three to work together, i tried the following three approaches and it seems like i need duplicate webviewClient and webChromeclients to make everything work which depend on them

I need a progress bar at the centre of my android webview it must be shown before the page loads and hides when the page is loaded. How can it be done? Can anyone help me?
This is my code for webview:
Bundle extras = getIntent().getExtras();
String title;
final String url;
if (!Datacon.checkInternetConnection(this)) {
Toast.makeText(getApplicationContext(), "Check your Internet Connection!", Toast.LENGTH_LONG).show();
} else {
if (extras != null) {
title = extras.getString("title");
url = extras.getString("url");
TextView text=(TextView) findViewById(R.id.textView1);
text.setText(title);
final WebView myWebView =(WebView)findViewById(R.id.WebView);
myWebView.loadUrl(url);
myWebView.getSettings().setLoadWithOverviewMode(true);
myWebView.getSettings().setUseWideViewPort(true);
myWebView.getSettings().setBuiltInZoomControls(true);
myWebView.getSettings().setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);
loadingProgressBar=(ProgressBar)findViewById(R.id.progressbar_Horizontal);
myWebView.setWebViewClient(new WebViewClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
Button refresh = (Button) actionBar.getCustomView().findViewById(R.id.but2);
refresh.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
myWebView.loadUrl(url);
}
});
}
}}
}
You need to override a couple of more methods in the WebViewClient :
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
loadingProgressBar.setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url) {
loadingProgressBar.setVisibility(View.GONE);
}
I'm assuming loadingProgressBar is a class field.
PS: As a side note I believe you overriding shouldOverrideUrlLoading is unnecessary. The default behaviour is to load the url, as you instruct it to do.
private void initializeProgressBar() {
if (progressBar == null){
progressBar = new ProgressDialog(this);
progressBar.setMessage(Constants.LOADING_MESSAGE);
progressBar.setCancelable(false);
}
}
Handler peogressBar = new Handler(){
public void handleMessage(android.os.Message msg) {
try{
switch (msg.what) {
case 1:
initializeProgressBar();
if(!progressBar.isShowing())
progressBar.show();
break;
case 2:
if (progressBar != null && progressBar.isShowing()) {
progressBar.dismiss();
progressBar = null;
}
break;
}
}catch(Exception e){
e.printStackTrace();
}
};
};
