WebView - break long words
Question
I create a service that loads data from a remote server and returns HTML data. This data I put to my WebView. All work good but have one problem: If some word is too long, WebView adds horizontal scroll. I add CSS file with break-work, word-wrap but it doesn't help.
JSONObject jsonObject = new JSONObject(strResult);
String content = jsonObject.getString("postContent");
TextView postTitle = (TextView) view.findViewById(R.id.postTitle);
postTitle.setText(jsonObject.getString("postTitle"));
WebView postContent = (WebView) view.findViewById(R.id.postContent);
postContent.getSettings().setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);
postContent.getSettings().setLoadWithOverviewMode(true);
postContent.getSettings().setUseWideViewPort(true);
postContent.getSettings().setBuiltInZoomControls(true);
postContent.getSettings().setJavaScriptEnabled(true);
postContent.loadDataWithBaseURL("file:///android_asset/", content, "text/html; charset=utf-8", "utf-8", null);

I did face completely similar problems and finally realized that I misused the css options for that. Just add word-break: break-all; word-break: break-word word-break: break-all; word-break: break-word to css style for body and/or headers and it's done
<head>
<style type="text/css">
body {text-align: center; word-break: break-all; word-break: break-word}
h1 {font-size:large; word-break: break-all; word-break: break-word}
h2 {font-size:medium; word-break: break-all; word-break: break-word}
</style> </head>
Some more details for css properties can be found here or there
Please be careful, as word-break option could seriously impact the readability of the text in WebView. Only use it when you really need it.

Apparently:
setLoadWithOverviewMode(true) loads the WebView completely zoomed out
setUseWideViewPort(true) makes the Webview have a normal viewport (such as a normal desktop browser), while when false the webview will have a viewport constrained to its own dimensions (so if the webview is 50px*50px the viewport will be the same size)
so i recommend you don't use setUseWideViewPort, the following code is for similar task that worked good:
final WebSettings webSettings = webView.getSettings();
webSettings.setRenderPriority(WebSettings.RenderPriority.HIGH);
webSettings.setEnableSmoothTransition(true);
webView.setBackgroundColor(Color.parseColor("#00000000"));
String before = "<html><head><style type=\"text/css\">@font-face {font-family: MyFont;src: url(\"file:///android_asset/fonts/w_yekan.ttf\")}body {font-family: MyFont;font-size: 14px;text-align: right;}</style></head><body><div style=\"direction:rtl !important;; text-align:right !important;\">";
String after = "</body></html>";
String myHtmlString = before + Utils.editString(DoaText) + after;
webView.getSettings().setDefaultZoom(WebSettings.ZoomDensity.FAR);
webView.loadDataWithBaseURL(null, myHtmlString, "text/html", "UTF-8", null);
i hope this answer be a good solution for you .
