Disabling autosuggestion on WebView?

Question

I have some HTML text inputs into a WebView, and I need to disable the autosuggetions on these inputs from Android, not from HTML (autocomplete=off).

How can I do th

Answer 1

The suggested above answers didn't help me. So I found next solution: I just created a simple wrapper for WebView and used it.

public class NoSuggestionsWebView extends WebView {
    public NoSuggestionsWebView(Context context) {
        super(context);
    }

    public NoSuggestionsWebView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public NoSuggestionsWebView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
        InputConnection ic = super.onCreateInputConnection(outAttrs);

        outAttrs.inputType &= ~EditorInfo.TYPE_MASK_VARIATION; /* clear VARIATION type to be able to set new value */
        outAttrs.inputType |= InputType.TYPE_TEXT_VARIATION_WEB_PASSWORD; /* WEB_PASSWORD type will prevent form suggestions */

        return ic;
    }
}

Answer 2

None of the above helped so after extensive search i found this which works perfect on webview as well as normal websites. Text area can be replaced by Input text fields too :)

<textarea class="form-control" id="comments" autocomplete="off" autocorrect="off"  spellcheck="false"></textarea>

Answer 3

If it already has the form data then setSaveFormData(false) won't stop it from using it. To clear the database you may have to do the following:

WebViewDatabase.getInstance(this).clearFormData();

Answer 4

I couldn't do this from Android's side, however in adding to the webview's text input spellcheck="false" did the trick.

<textarea spellcheck="false"></textarea>

Answer 5

This problem vexed me for quite a while but the solution is very simple:

webview.getSettings().setSaveFormData(false);

I wrote about it here:

Answer 6

In Android 8 and above, you should set importance of a textview subclass for system auto-fill feature:

android:importantForAutofill="noExcludeDescendants"

Official reference: Optimize your app for autofill

Furthermore, You might try to delete the "Web Data" sqlite file in data/data/{your-app-package}/app_webview when webview isn't in use for security's sake.
