I've been having issues trying to get webview from stop zooming in when a user clicks a input field on webview. How can I keep webview from stop zooming in?
Heres my code:
wv = (WebView) findViewById(R.id.webView1);
WebSettings webSettings = wv.getSettings();
wv.setWebViewClient(new WebViewClient());
wv.getSettings().setLoadWithOverviewMode(true);
wv.getSettings().setUseWideViewPort(true);
wv.getSettings().setDisplayZoomControls(false);
wv.getSettings().setBuiltInZoomControls(false);
wv.getSettings().setSupportZoom (true);
wv.getSettings().setJavaScriptEnabled(true);
wv.getSettings().setDefaultZoom(ZoomDensity.FAR);
String form = "<form action='demo_form.asp'><input type='text' name='email' style='font-size: 200%;width:78%;float:left'><input type='submit' value='Submit' style='float:right;width:20%;font-size: 200%'></form>";
String summary = "<html><body>"+form+"</body></html>";
wv.loadData(summary, "text/html", null);
The webview in my app (where i present some RSS news) uses to blink when i scroll,or sometimes if i read the article.
How can i fix it?
the problem is the same in my 4.1.1 device and in the emulator.
this is my webview:
final WebView desc = (WebView) view.findViewById(R.id.desc);
desc.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
// super.onPageFinished(view, url);
desc.loadUrl("javascript:(function() { "
+ "document.getElementsByTagName('img')[0].style.display = 'none'; "
+ "})()");
}
});
// Set webview properties
WebSettings ws = desc.getSettings();
ws.setSupportZoom(true);
// ws.setDisplayZoomControls(true);
ws.setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);
ws.setLightTouchEnabled(false);
ws.setPluginState(PluginState.ON);
ws.setJavaScriptEnabled(true);
ws.setUserAgentString("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.36 (KHTML, like Gecko) Chrome/13.0.766.0 Safari/534.36");
// ws.setLoadsImagesAutomatically(false);
// desc.requestFocus(View.FOCUS_DOWN);
desc.loadDataWithBaseURL("", DESC,
"text/html", "UTF-8", null);
put android:hardwareAccelerated="false" to that activity.
I hope it may helps
Thanks,

when you set android:hardwareAccelerated="false" to that activity,you'd better not use animation in that activity.otherwise animation will be so bad.
you could set webview.setLayerType(View.LAYER_TYPE_SOFTWARE,null);
it also close hardwareAccelerated
webview.setVisibility(View.VISIBLE);
webview.getSettings().setJavaScriptEnabled(true);
//webview.getSettings().setPluginsEnabled(true);
webview.getSettings().setPluginState(PluginState.ON);
webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
webview.getSettings().setAllowFileAccess(true);
webview.getSettings().setBuiltInZoomControls(true);
webview.getSettings().setBlockNetworkLoads(false);
webview.setWebChromeClient(new WebChromeClient() {});
final String mimeType = "text/html";
final String encoding = "UTF-8";
String html = getHTML1();
webview.loadDataWithBaseURL("", html, mimeType, encoding, "");
}
public String getHTML1() {
Log.d("trailer_2 HTML","ok");
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/"
+ "H7Ht-m2QMDY"
+ "?fs=0\" frameborder=\"0\">\n"
+ "</iframe>\n";
return html;
}
I was tried lot of.Its working for Tablet Devices but not working for mobile devices ?
I have also mention hardwareAcelator=true in manifest bur not working ?
I am parsing xml and then loading it to web view. After parsing, I am creating four strings so that I could append all strings to one view. I am able to get two views on the web view, but not the first two strings.
Please suggest in my code, where I am going wrong and the correct way to get the formatted html strings on the web view.
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
String chapterTitle = "";
String SubChapterTitle="";
String chapterIntro ="";
String chapterContent="";
View view = convertView;
if (convertView == null) {
// view = inflater.inflate(resourceid, null);
view = getLayoutInflater().inflate(R.layout.webviewitem, null);
}
synchronized (view) {
WebView wv = (WebView) view.findViewById(R.id.contentWebView);
WebSettings settings = wv.getSettings();
settings.setUseWideViewPort(true);
settings.setLoadWithOverviewMode(true);
settings.setJavaScriptEnabled(true);
settings.setDefaultZoom(ZoomDensity.FAR);
// wv.setBackgroundColor(0);
wv.setVerticalScrollBarEnabled(false);
wv.setHorizontalScrollBarEnabled(false);
/*String txtChapTitle = Intro.book.getsecretList().get(position)
.getChtitle().toString();*/
if (!(Intro.book.getsecretList().get(position).getChtitle()
.toString().equals(""))){
chapterTitle = "<b><fontSize=4>"+Intro.book.getsecretList().get(position)
.getChtitle().toString()+"</font></b>";
}
if (!(Intro.book.getsecretList().get(position)
.getSubtitle() == null)) {
SubChapterTitle = "<b><fontSize=4>"+Intro.book.getsecretList().get(position)
.getSubtitle().toString()+"</font></b>";
}
if (!(Intro.book.getsecretList().get(position)
.getIntro() == null)) {
chapterIntro = "<b><fontSize=2>"+Intro.book.getsecretList().get(position)
.getIntro().toString()+"</font></b>";
}
if (!(Intro.book.getsecretList().get(position)
.getContent() == null)) {
chapterContent = "<fontSize=2>"+Intro.book.getsecretList().get(position)
.getContent().toString()+"</font>";
}
StringBuilder content = new StringBuilder();
content.append(chapterTitle+SubChapterTitle+chapterIntro+chapterContent);
JsInterface Jsi = new JsInterface();
Jsi.wordDef = content ;
Log.v("Content", "" +content);
wv.addJavascriptInterface(Jsi, "interfaces");
wv.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
view.setHapticFeedbackEnabled(false);
}
});
wv.setWebChromeClient(new WebChromeClient() {
#Override
public boolean onJsAlert(WebView view, String url,
String message, JsResult result) {
return super.onJsAlert(view, url, message, result);
}
});
wv.loadUrl("file:///android_asset/wordview.html");
}
return view;
}
}
I am able to get chapterIntro and chaptercontent on the web view, but not the first two strings.
i have successfully done by below line
//data == html data which you want to load
String data = "Your data which you want to load";
WebView webview = (WebView)this.findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.loadData(data, "text/html; charset=utf-8", "UTF-8");
Or You can try
webview.loadDataWithBaseURL(null, data, "text/html", "utf-8", null);
To load your data in WebView. Call loadData() method of WebView
webView.loadData(yourData, "text/html; charset=utf-8", "UTF-8");
You can check this example
http://developer.android.com/reference/android/webkit/WebView.html
Passing null would be better. The full codes is like:
WebView wv = (WebView)this.findViewById(R.id.myWebView);
wv.getSettings().setJavaScriptEnabled(true);
wv.loadDataWithBaseURL(null, "<html>...</html>", "text/html", "utf-8", null);
I was using some buttons with some events, converted image file coming from server.
Loading normal data wasn't working for me, converting into Base64 working just fine.
String unencodedHtml ="<html><body>'%28' is the code for '('</body></html>";
tring encodedHtml = Base64.encodeToString(unencodedHtml.getBytes(), Base64.NO_PADDING);
webView.loadData(encodedHtml, "text/html", "base64");
Find details on WebView
After struggling the 2 hours of effort I found the solution
I want to run this code in webview
"<div style='width:100%;height:0px;position:relative;padding-bottom:56.250%;background:#000;'><iframe src='https://www.scorebat.com/embed/v/N09DWllRdlNraERnSXRRa1VJMTF4Zz09/?token=MTkxMTdfMTY1MjEyMzY2MF9kNzRkZTI4MTc3ZDAxZTNkOTQyOTg1OWE3MTcyYmFhY2EyYTI2YTZh&utm_source=api&utm_medium=video&utm_campaign=apifd' frameborder='0' width='100%' height='100%' allowfullscreen allow='autoplay; fullscreen' style='width:100%;height:100%;position:absolute;left:0px;top:0px;overflow:hidden;'></iframe></div>"
But I only got the white screen after trying all the answers
Now do this as your code will also work
WebView webview = (WebView) findViewById(R.id.webview);
webview.setWebViewClient(new WebViewClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webview.getSettings().setPluginState(WebSettings.PluginState.ON);
webview.getSettings().setMediaPlaybackRequiresUserGesture(false);
webview.setWebChromeClient(new WebChromeClient());
webview.loadDataWithBaseURL(null, data, "text/html", "UTF-8", null);
Here webview.loadDataWithBaseURL(null, data, "text/html", "UTF-8", null); data is the HTML and javascript code
Add this line in your application tag as well
android:hardwareAccelerated="true"
I hope it will solve your issue

trying to add js and div to webview. showing a blank screen.
i am trying to do like functionality for android app. please help me.
Check the output of your logcat and add something like this:
/* WebChromeClient must be set BEFORE calling loadUrl! */
view.setWebChromeClient(new WebChromeClient() {
#Override
public boolean onJsAlert(WebView view, String url, String message, final android.webkit.JsResult result) {
Log.e("js ", message);
return false;
}
});/ // for debugging convenience.
to also log the javascript errors to logcat.
