问题 I'm facing a huge problem developing an Android app which use a Webview to display datas. The website i'm using in the webview use localStorage API of HTML 5. To enable this feature i've set the webview setting like this : webview.getSettings().setDomStorageEnabled(true); webview.getSettings().setJavaScriptEnabled(true); So the localStorage API works but when I close the app (and kill the process), localStorage is completly erased and when I reload it, all my datas are lost.

I would like to have a text input field containing the "$" sign in the very beginning, and no matter what editing occurs to the field, for the sign to be persistent.

Here's a basic kickoff example: .currencyinput { border: 1px inset #ccc; } .currencyinput input { border: 0; } <span class="currencyinput">$<input type="text" name="currency"></span> Use a parent .input-icon div
