I have a container Webview which plays videos.I have fixed the size of container inside xml file by 200dp. Webview loads data by loading html format. Video is playing smoothly but problem is video height doesn't fit to the given size and user can drag video vertically up and down.Videos width is adjusting according to device size.But the problem is with adjusting video height.
xml code for container
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="200dp">
<WebView
android:id="#+id/myWeb"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:alwaysDrawnWithCache="true"
/>
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:id="#+id/progressBar3"
/>
</RelativeLayout>

stringBuilder.append("</body>" +
"</html>");
return stringBuilder.toString();
}
Sp what i am looking for is how to fit the video content inside given height, so that user wont be able to drag the video vertically?.It should adjust the video within the view's height.
You've given style='width:100%; height:300' in your html code. Try replacing it with height:100% or try reducing the height to 200px. :)

I want to display youtube URL in a web view. But it is not loading into the web view.
Here is my code.
WebView web_view = (WebView) findViewById(R.id.web_view);
web_view.setWebViewClient(new WebViewClient());
web_view.getSettings().setJavaScriptEnabled(true);
web_view.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
web_view.getSettings().setPluginState(WebSettings.PluginState.ON);
web_view.getSettings().setMediaPlaybackRequiresUserGesture(false);
web_view.setWebChromeClient(new WebChromeClient());
web_view.loadUrl("https://www.youtube.com/watch?v=s8n16rns-iM");
the video is not loaded into the web view.It is showing error:
[INFO: CONSOLE(16)] "The key "target-densitydpi" is not supported.", source: https://m.youtube.com/watch?v=s8n16rns-iM
try this
String frameVideo = "<html><body>Video From YouTube<br><iframe width=\"420\" height=\"315\" src=\"https://www.youtube.com/watch?v=ue80QwXMRHg&app=desktop\" frameborder=\"0\" allowfullscreen></iframe></body></html>";
WebView displayYoutubeVideo = (WebView) findViewById(R.id.mWebView);
displayYoutubeVideo.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
});
WebSettings webSettings = displayYoutubeVideo.getSettings();
webSettings.setJavaScriptEnabled(true);
displayYoutubeVideo.loadData(frameVideo, "text/html", "utf-8");
To get a html frame for a particular video, use this function with a Video Id,
public String getHtmlfromVideoId(String videoId) {
String html = "<iframe class=\"youtube-player\" " + "style=\"border: 0; width: 100%; height: 96%;"
+ "padding:0px; margin:0px\" " + "id=\"ytplayer\" type=\"text/html\" "
+ "src=\"http://www.youtube.com/embed/" + videoId
+ "?&theme=dark&autohide=2&modestbranding=1&showinfo=0&autoplay=1\fs=0\" frameborder=\"0\" "
+ "allowfullscreen autobuffer " + "controls onclick=\"this.play()\">\n" + "</iframe>\n";
return html;
}
Video Id usually comes after the v parameter of the youtube url. For example, the Video Id of https://www.youtube.com/watch?v=s8n16rns-iM&app=desktop is s8n16rns-iM
Once you get the html frame, load it directly in the WebView,
webView.loadData(html, "text/html", "UTF-8");
I am using an android WebView and I want to load webpage on my android device but display only some parts of webpage, not the whole page.
Is this possible?
I think what you want to do is remove some content from your HTML page and then display it in the WebView. This is possible via javascript so just before you display the page add some javascript code that will remove the elements you don't want.
LIKE
final WebView mWebView = (WebView) findViewById(R.id.mWebViewId);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url)
{
mWebView.loadUrl("javascript:(function() { " +
"document.getElementById('tableid')[0].style.display='none'; " +
"})()");
}
});
mWebView.loadUrl(youUrl);
Just replace document.getElementsByTagName('tableid') with document.getElementsByTagName('theElementYouWantToRemove') for every element and you're set. Original solution can be found at Display a part of the webpage on the webview android
for those who still looking for a solution:
WebView webView = findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url)
{
mWebView.loadUrl("javascript:(function() { " +
"document.getElementsByClassName('className1')[0].remove();
document.getElementsByClassName('className2')[0].remove();
document.getElementsByClassName('className3')[0].remove();" +
"})()");
}
});
webView.loadUrl(url);
In Kotlin in this way:
view.webViewClient = object : WebViewClient() {
override fun onPageFinished(view: WebView, url: String) {
view.loadUrl(
"javascript:(function() { " +
"var head = document.getElementsByClassName('header')[0].style.display='true'; " +
"var head = document.getElementsByClassName('art-bnr')[0].style.display='none'; " +
"var head = document.getElementsByClassName('container-box')[0].style.display='none'; " +
"var head = document.getElementsByClassName('blog-sidebar')[0].style.display='none'; " +
"var head = document.getElementsByClassName('footer-container')[0].style.display='none'; " +
"})()"
) } }
view.loadUrl(url)
i need to display another website into my android webview without it's header and footer
wb.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url)
{
wb.loadUrl("javascript:(function() { " +"document.getElementsByTagName('header')[0].style.display=\"none\"; " + "})()");
}
});
wb.loadUrl(url);
setContentView(wb);
Why not use iframe?
Try something like this -
String iframe = "<iframe scrolling=\"no\" src=\"YOUR URL\"" +
"width=\"400px\" height=\"300\"></iframe>";
webview.getSettings().setJavaScriptEnabled(true); //be sure to enable this or
//page might not load properly
webview.loadDataWithBaseURL("", iframe, "text/html", "UTF-8", "");
//loading iframe
You can customize the iframe code according to your needs. Be sure to add \ before every " in your HTML Code.
I want to load youtube video to Android webview using iframe
here is my layout Xml

wv.loadDataWithBaseURL("", html , "text/html", "UTF-8", "");
}
}
Also I provide <uses-permission android:name="android.permission.INTERNET"/>
& android:hardwareAccelerated="true"
when I run this I didn't get any result its just showing a black screen
I tried this .but this provide me video on .3gp Quality . but I need the videos from youtube on original quality. That's why I am using iframe.
I try code using <object></object> and <video></video> instead of iframe. but it didn't solve my issue.
when I run this code on emulator it shows
Before Pressing Play Button
After Pressing Play button on video
I think we cannot stream videos on emulator since it is a virtual device
But when I run this on phone it's not even showing this result.
I try iframe with a document attach to it works fine on phone as well as emulator
String customHtml = "<iframe src='http://docs.google.com/viewer?url=http://www.iasted.org/conferences/formatting/presentations-tips.ppt&embedded=true' width='100%' height='100%' style='border: none;'></iframe>";
So please help me to load videos to this frame.
(I run it on phone). What's the problem?
also will iframe work on Android 2.1?

As stated in the android Webview documentation,
HTML5 Video support
In order to support inline HTML5 video in your application, you need to have hardware acceleration turned on, and set a WebChromeClient.
For full screen support, implementations of onShowCustomView(View, WebChromeClient.CustomViewCallback) and onHideCustomView() are required, getVideoLoadingProgressView() is optional.
This worked for me:
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
String frameVideo = "<html><body>Youtube video .. <br> <iframe width=\"320\" height=\"315\" src=\"https://www.youtube.com/\" frameborder=\"0\" allowfullscreen></iframe></body></html>";
mWebView.loadData(frameVideo, "text/html", "utf-8");
mWebView.loadUrl("http://www.youtube.com/");
mWebView.setWebViewClient(new WebViewClient());
Try this its working fine..
mWebView = (WebView) findViewById(R.id.web);
String videoURL = "https://www.youtube.com/embed/R52bof3tvZs";
String vid = "<html><body style=\"margin: 0; padding: 0\"><iframe width=\"100%\" height=\"100%\" src=\""+videoURL+"\" type=\"text/html\" frameborder=\"0\"></iframe><body><html>";
WebChromeClient mWebChromeClient = new WebChromeClient(){
public void onProgressChanged(WebView view, int newProgress) {
}
};
mWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
mWebView.setWebChromeClient(mWebChromeClient);
mWebView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
mWebView.loadUrl("javascript:(function() { document.getElementsByTagName('video')[0].play(); })()");
}
});
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setAppCacheEnabled(true);
mWebView.setInitialScale(1);
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
if (Build.VERSION.SDK_INT < 17) {
Log.i("GPSNETWORK", "<17");
} else {
Log.i("GPSNETWORK", Build.VERSION.SDK_INT+">=17");
mWebView.getSettings().setMediaPlaybackRequiresUserGesture(false);
}
String myUrl = "<html><body style='margin:0px;padding:0px;'>\n" +
" <script type='text/javascript' src='http://www.youtube.com/iframe_api'></script><script type='text/javascript'>\n" +
" var player;\n" +
" function onYouTubeIframeAPIReady()\n" +
" {player=new YT.Player('playerId',{events:{onReady:onPlayerReady}})}\n" +
" function onPlayerReady(event){player.mute();player.setVolume(0);player.playVideo();}\n" +
" </script>\n" +
" <iframe id='playerId' type='text/html' width='1280' height='720'\n" +
" src=\""+videoURL+"\"?enablejsapi=1&rel=0&playsinline=1&autoplay=1&showinfo=0&autohide=1&controls=0&modestbranding=1' frameborder='0'>\n" +
" </body></html>";
mWebView.loadData(""+Html.fromHtml(myUrl), "text/html", "UTF-8");
I'm no expert in Android webview, but I encountered similar problems with web page.
What I had to do was to use tag and made sure it had onclick="this.play(); in the tag. The onclick event was specifically for Android. Chrome, Safari, Firefox didn't need it.
For example:
<video id="video" width="320" height="240" autobuffer controls onclick="this.play();">
Without the onclick, Android browser would not work. Since webview is calling the browser, I suspect it's the same.
And make sure in the source tag you do NOT use codec attribute.
Hope this helps you.
It's not exactly a direct answer to your question, but I believe you might want to use the newly released Android Youtube API. It should allow adding youtube video playback into your apps, so you don't have to inject them into a webview in an iFrame.. That's just silly, and not all Android devices will have Flash installed :)
https://developers.google.com/youtube/android/player/
You can visit my question again. Iv'e created a function that gives you all of the youtube video's direct links (including hq links). Now you can use mp4 and so instead of the poor 3gp.
Using WebChromeClient allows you to handle Javascript dialogs, favicons, titles, and the progress:
wv = setWebChromeClient(new WebChromeClient());
It's working properly
My Java file
String path="<iframe src='https://www.youtube.com/embed/94zICkZLQpY' width='100%' height='100%' style='border: none;'></iframe>";
webView.loadData(path,"text/html","utf-8");
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient());
Here 94zICkZLQpY is the embedded code you will get in any youtube video
My normal youtube video link which is watchable is
https://www.youtube.com/watch?v=94zICkZLQpY&feature=youtu.be
I want to load an image at the web view, but it shows all at top_left of the web view. My picture is on the internet not local.
gifView.loadUrl(mImageUrl);
gifView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
view.getSettings().setLoadsImagesAutomatically(true);
if (mProgressBar != null) {
mProgressBar.setVisibility(View.GONE);
}
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
if (mProgressBar != null) {
mProgressBar.setVisibility(View.VISIBLE);
}
}
});
Here is my xml:::
<WebView
android:id="#+id/gif_image"
android:background="#null"
android:layout_gravity="center"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
Edit:i used:
String HTML_FORMAT = "<html><body style=\"text-align: center; background-color: null; vertical-align: middle;\"><img src = \"%s\" /></body></html>";
final String html = String.format(HTML_FORMAT, mImageUrl);
gifView.loadDataWithBaseURL("", html, "text/html", "UTF-8", "");
but my image only Horizontal Center，how to center
Try this.
myWebView.loadData("<html><head><style type='text/css'>body{margin:auto auto;text-align:center;} img{width:100%25;} </style></head><body><img src='www.mysite.com/myimg.jpeg'/></body></html>" ,"text/html", "UTF-8");
I did it by using some code and xml :
<WebView android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="251dp"
android:layout_below="#+id/download"
android:layout_marginTop="20dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"/>
and this (for horizental center) :
WebView loading = (WebView)rootView.findViewById(R.id.webview);
loading.getSettings().setDefaultZoom(WebSettings.ZoomDensity.FAR);
loading.loadDataWithBaseURL("file:///android_asset/", "<html><center><img src=\"done.png\"></html>", "text/html", "utf-8", "");
Or this for (horizontal & vertical center) :
WebView loading = (WebView)rootView.findViewById(R.id.webview);
loading.getSettings().setDefaultZoom(WebSettings.ZoomDensity.FAR);
loading.loadDataWithBaseURL("file:///android_asset/", "<html>\n" +
"<body bgcolor=\"white\">\n" +
" <table width=\"100%\" height=\"100%\">\n" +
" <tr>\n" +
" <td align=\"center\" valign=\"center\">\n" +
" <img src=\"loading.gif\">\n" +
" </td>\n" +
" </tr>\n" +
" </table>\n" +
"</body>", "text/html", "utf-8", "");
Try something like this:
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
String data = "<body><center><img width=\"" + width + "\" src=\"" + url
+ "\" /></center></body></html>";
webview.loadData(data, "text/html", null);
Try this, this will make the content fit to your webview
WebView web = (WebView) findViewById(R.id.gif_image);
web.getSettings().setDefaultZoom(ZoomDensity.FAR);
Do you use Linear layout? So you will require to use the gravity property of the parent linear layout.
A good explanation of gravity in android: http://sandipchitale.blogspot.com/2010/05/linearlayout-gravity-and-layoutgravity.html
The reason is not in the webview, it is the html code.
W3c wants that "text-align" should no longer take effekt on block elements like images.
You can read more at center-image-using-text-align-center
So either you make your image display:inline or you center it in a different way e.g.
.center {
left: 50%;
margin-left: -50%;
}
