Read Keyboard events in Android WebView


Caution! This solution supports only English letters.

Accomplished without any access to the HTML source code or JS events. Works for me on Android 5.0.2 for both soft and hardware keyboards.

public class MyWebView extends WebView {    @Override    public InputConnection onCreateInputConnection(EditorInfo outAttrs) {        return new BaseInputConnection(this, false); //this is needed for #dispatchKeyEvent() to be notified.    }    @Override    public boolean dispatchKeyEvent(KeyEvent event) {        boolean dispatchFirst = super.dispatchKeyEvent(event);        // Listening here for whatever key events you need        if (event.getAction() == KeyEvent.ACTION_UP)            switch (event.getKeyCode()) {                case KeyEvent.KEYCODE_SPACE:                case KeyEvent.KEYCODE_ENTER:                    // e.g. get space and enter events here                    break;            }        return dispatchFirst;    }}

The trick here is overriding the system-provided input implementation of InputConnection with a simplified one. Preventing developers from accessing the events by default was made by Googlers on purpose. Because the key event input isn't the only one anymore. There're gestures, voice and more is coming. Official recommendation is to "stop relying on legacy key events for text entry at all". Check out more details here: https://code.google.com/p/android/issues/detail?id=42904#c15


You can use onUnhandledKeyEvent() function overrid on WebViewClient class. Works perfectly for me.

onUnhandledKeyEvent

@Overridepublic void onUnhandledKeyEvent(WebView view, KeyEvent event) {      return;}whenever a user presses any key on the keyboard, this event will get fire.Please let me know if that's works for you?


you can use javascript like this

<body>        <div contenteditable="true" id='box'></div></body>    <script>        box.addEventListener('keydown',e=>{            if(e.keyCode ===13){                alert('pressed enter key')            }        })    </script>
