Directly put html code in a WebView (Android) - android

While using WebView, we usually put a URL for it:
WebView.loadUrl(myURL);
but it is possible to put HTML code directly?? So that it will be in a logic that:
WebView.loadContent ( <html><head><script></script></head><body>....</body></html> );
Thanks.

Check out this:
http://developer.android.com/reference/android/webkit/WebView.html
// OR, you can also load from an HTML string:
String summary = "<html><body>You scored <b>192</b> points.</body></html>";
webview.loadData(summary, "text/html", null);

String yourhtmlpage = "<html><body>You scored <b>hello world</b> points.</body></html>";
webview.loadDataWithBaseURL(null, yourhtmlpage, "text/html", "UTF-8", null);

Try this code. It works for me.
WebSettings settings = mDesc.getSettings();
settings.setDefaultTextEncodingName("utf-8");
mDesc.loadData(mDescText, "text/html; charset=utf-8",null);

Webview's loadData() is not working in android 10.0 (Q)

Here i am trying to load Html code as string in webview's loadData() .Nothing is happen over this mehtod but same method is working like charm in below sdk 29.
webview.loadData(html_code,"text/html",null);
Note : Here i am not performing any encoding or decoding operation on string.I am simply passing it as string to above method.
Use this code, it will work.
String newhtml_code = Base64.encodeToString(html_code.getBytes(), Base64.NO_PADDING);
testWebView.loadData(newhtml_code,"text/html", "base64");
Try calling
String encodedHtml = Base64.encodeToString(html_code.getBytes(), Base64.NO_PADDING);
webview.getSettings().setJavaScriptEnabled(true);
before
webview.loadData(encodedHtml , "text/html", "base64");
like below
String html_code= "<html><body>Your Actualtext.</body></html>";
String encodedHtml = Base64.encodeToString(html_code.getBytes(), Base64.NO_PADDING);
webview.getSettings().setJavaScriptEnabled(true);
webview.loadData(encodedHtml , "text/html", "base64");
for more details refer to this link
manifest file in
android:usesCleartextTraffic="true"
and
WebSettings settings = wb_webview.getSettings();
settings.setJavaScriptEnabled(true);
settings.setSupportZoom(true);
settings.setBuiltInZoomControls(true);
String html_code = "html code";
wb_webview.loadData(Base64.encodeToString(html_code.getBytes(), Base64.NO_PADDING) , "text/html", "base64");
Now it is working after performing base-64 encoding to string html_code.
Issue resolved by passing html_code string as per given instruction in docs
I came up with another solution by using loadDataWithBaseURL
e.g.
webView.loadDataWithBaseURL(null, html, "text/html", null, null)
It should use less CPU and memory resource as no need Base64 calculation and storing.
I facing the same issue and fix it by using loadDataWithBaseURL() instead loadData() method
mWebView.loadData(mHtml, "text/html", "UTF-8");
solution:
mWebView.loadDataWithBaseURL(null,mHtml,"text/html", "UTF-8", null);

Android: How to convert local string(html) to html page and display in the Webview

The string contains the html page code. As the requirement, it better not to store in the file. How to represent it in the Webview?
Hi if you string contains the html page code then you can directly load in Webview like below.
webView.loadData(webData, "text/html; charset=UTF-8", null);
Try this:
WebView wv = (WebView)this.findViewById(R.id.myWebView);
wv.getSettings().setJavaScriptEnabled(true);
wv.loadDataWithBaseURL(null, /*Your HTML string*/, "text/html", "utf-8", null);
Check out this: http://developer.android.com/reference/android/webkit/WebView.html
String summary = "<html><body>Your <b>HTML</b> code.</body></html>";
webview.loadData(summary, "text/html", null);

How to avoid unnecessary characters in WebView

I am setting String in WebView in Android, but i am getting such characters http://img4.imageshack.us/img4/5200/hkgm.jpg. How to avoid them ? IF i put a log and see then it will be proper but only in WebView it is not working properly
Thanks in advance
Code :
String text = "<html><body style=\"text-align:justify\"> %s </body></Html>";
String summary = rssStr.get(position).getEncodedContent();
Log.d("String", summary);
web.loadData(String.format(text, summary), "text/html", "utf-8");
By setting the Encoding type in the Webview can resolve this issue,
wv.loadDataWithBaseURL(null, data, "text/html", "UTF-8", null);

android webkit change font size?

how could I change my custom webview font size ?
String summary = "<html><body>You scored <b>192</b> points.</body></html>";
webView.loadData(summary, "text/html", "utf-8");
I want to control the font(text) size of that string summary at webview.
Can I control with addJavascriptInterface (Object obj, String interfaceName) ?
You can use:
WebSettings webSettings = webView.getSettings();
webSettings.setTextSize(WebSettings.TextSize.LARGEST);
