I understand how to set the value of a edit box in WebView, and in a browser on PC with Javascript.

It is basically first find out the ID of the edit box (text), then s

Answer 1

The problem is solved. It was because of the way I call javascript in java code.

code like

mWebView.loadUrl("javascript: [your javascript code]");

sometimes work, but it doesn't work in all the case. At least it doesn't work for the following case when I tried to set the textbox in a webview:

mWebView.loadUrl("javascript: document.getElementById('xxxxxxxx').value= 'test'");

but it should work if you call the javascript as a function:

mWebView.loadUrl("javascript: (function() {document.getElementById('xxxxxxxx').value= 'test';}) ();" );

That fixed my problem. Hope it is helpful.
