Why is Android WebView refusing user input?

I'm developing an Android application that uses a WebView to display the login page for Facebook. The page loads beautifully, and I'm able to select the username/password textboxes, but typing in them will not work. That is, they definitely have input focus (they have the orange focus highlight box and a flashing cursor), but typing in them does absolutely nothing. I'm not certain, but I think maybe the form buttons are also playing up - they appear to be simply refreshing the page, rather than submitting the form.

Just to be clear, although I'm particularly interested in getting Facebook running, I'm sure that this isn't a Facebook issue since other websites (Google, etc) also display the same behavior.

Does anyone have any ideas what might be the issue?

Turns out that it was apparently the WebView not having focus that was the issue.

I discovered that using the arrow keys to get focus on the textboxes caused them to work, so I theorised that there was an issue somewhere with something not having focus, most likely the WebView not having focus. Sure enough, adding the following line seemed to fix the problem:

webView.requestFocus(View.FOCUS_DOWN);

I'm still at a loss to explain exactly why the issue occurred in the first place - the textboxes should work whether they receive focus from being tapped upon or through being "arrowed" to - but at least I have a solution that appears to work.

Thanks for your input wf.

These are most have

webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setUseWideViewPort(true);
webview.requestFocus(View.FOCUS_DOWN);

and if still not working then use one alternative below

Alternative 1

webview.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:
                case MotionEvent.ACTION_UP:                     
                    if (!v.hasFocus()) {
                        v.requestFocus();
                    }
                    break;
            }               
            return false;
        }
    });

Alternative 2

webview.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
            case MotionEvent.ACTION_UP:
                v.requestFocusFromTouch();  
                break;
        }               
        return false;
    }

});

Not sure if it's the problem since other websites also display the same behavior, but have you enabled javascript? A WebView does not enable it by default.

WebView webView = (WebView)findViewById(R.id.yourWebView);
webView.getSettings().setJavaScriptEnabled(true);

By default, In Android, Webview allow user input with basic configurations:-

android:focusable="true"
android:focusableInTouchMode="true"

& enabled JavaScript but make sure there is not any activity/fragment level focusability blockage, in my case

android:descendantFocusability="blocksDescendants"

just removed this, worked for me. So cross-check such cases & fix them accordingly.
