1st way
mainContent.getSettings().setJavaScriptEnabled(true);
WebSettings webSettings = mainContent.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setBuiltInZoomControls(true);
mainContent.requestFocusFromTouch();
mainContent.setWebViewClient(new WebViewClient());
mainContent.setWebChromeClient(new WebChromeClient());
mainContent.loadUrl("file:///android_asset/"+filename.get(position));
Typeface font = Typeface.createFromAsset(getAssets(), "myfont.ttf");
webSettings.setFixedFontFamily(font);
webSettings.setDefaultFontSize(20);
2nd way
I have get the content of html and i have passed into a string, i can't able to pass into it, if the content passed correctly this will work.
mainContent.getSettings().setJavaScriptEnabled(true);
WebSettings webSettings = mainContent.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setBuiltInZoomControls(true);
mainContent.requestFocusFromTouch();
mainContent.setWebChromeClient(new WebChromeClient());
mainContent.loadUrl("file:///android_asset/"+filename.get(position));
mainContent.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
mainContent.setWebViewClient(null);
mainContent.loadUrl("javascript:window.HTMLOUT.processHTML('<div>'+document.getElementsByTagName('div')[0].innerHTML+'</div>');");
String pish = "<html><head><style type=\"text/css\">@font-face {font-family: MyFont;src: url(\"file:///android_asset/fonts/Kelvetica.ttf\")}body {font-family: MyFont;font-size: medium;text-align: justify;}</style></head><body>";
String pas = "</body></html>";
String myHtmlString = pish + page + pas; // here i can't able to get the `page`
mainContent.loadDataWithBaseURL(null,myHtmlString, "text/html", "UTF-8", null);
and in my activity
class MyJavaScriptInterface {
@SuppressWarnings("unused")
public void processHTML(final String html) {
runOnUiThread(new Runnable() {
public void run() {
Spanned page = Html.fromHtml(html);
System.out.println("content"+page);
}
});
}
}
i need to pass this page into above code
3rd way
mainContent.getSettings().setJavaScriptEnabled(true);
WebSettings webSettings = mainContent.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setBuiltInZoomControls(true);
mainContent.requestFocusFromTouch();
mainContent.addJavascriptInterface(new MyJavaScriptInterface(), "HTMLOUT");
mainContent.loadUrl("file:///android_asset/"+filename.get(position));
mainContent.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
mainContent.setWebViewClient(null);
mainContent.loadUrl("javascript:(function() { var s=document.createElement('style');s.innerHTML ="
+ " '@font-face{font-family:ZawGyi-One;src:url('file:///android_asset/fonts/zeroesthree.ttf');}"
+ "body,div,h1,h2,h3,input,textarea{font-family:ZawGyi-One! important;}';"
+ "document.getElementsByTagName('head')[0].appendChild(s);document.getElementsByTagName('body')[0].style.fontFamily = \"ZawGyi-One\"})()");
}
});
I have tried like this. I can't able to change the fonttype. Any one have idea please share it. I'm working on this problem for past two days. Thanks in Advance.

You can do this in two way
Here is example : CSS font_first.css:
.box_heading{
width:340px;
text-align:center;
font-family:Arial, Helvetica, sans-serif;
color:#000;
font-size:20px;
font-weight:normal;
margin-top:14px;
float:left;
text-transform:uppercase;}Html: index.html
If you are doing this with second method you just need to call changeFont() from android webview for this you have to call mainContent.loadUrl("javascript:changeFont()")
EDIT
If so you can try this : myWebView.loadUrl("javascript:document.getElementById('navigationText')style.fontFamily ='"+fontName+"');
