I have a USB barcode scanner which is plugged into the device with USB OTG. Because this is picked up as a keyboard HID device, the soft keyboard is disabled when inputs are focused.
I currently have a method which triggers the keyboard from JavaScript.
class JsObject {
@JavascriptInterface
public void InvokeKeyboard() {
InputMethodManager inputMethodManager = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.showSoftInput(findViewById(R.id.webView), InputMethodManager.SHOW_FORCED);
}
}
webview.addJavascriptInterface(new JsObject(), "Android");
I'm basically wanting it to open the keyboard on the following action inside the webview.
const button = document.querySelector('.fire-keyboard');
button.addEventListener('click', () => Android.InvokeKeyboard());
It works when called from the webview manually but I want to be able to click a button which triggers it, and clicking the button loses the input box focus.
Just to add, I don't want the keyboard to show when focusing an input box, only to show when a button is clicked to trigger it. By default it shows on focus.

Turns out I just needed to have this hardware toggle on.

May be it is due to device you are using. I made a sample according to your scenario and successfully run it on Nexus5 device which I am using.
Just use document.getElementById("mytextfield").focus(); in JS code which did the trick.
Sample html code
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<form name="myform">
<input type="text" id="mytextfield">
</form>
<input type="button" value="Click Me!" onClick="executeAndroidCode()" />
<script type="text/javascript">
function executeAndroidCode() {
Android.execAndroid();
document.getElementById("mytextfield").focus(); //this line did the trick after click on button
}
</script>
</body>
</html>
Save this file in asset named index.html
JavaScriptInterface
public class WebAppInterface
{
Context mContext;
/** Instantiate the interface and set the context */
WebAppInterface(Context c) {
mContext = c;
}
@JavascriptInterface
public void execAndroid() {
InputMethodManager inputMethodManager = (InputMethodManager)
getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.showSoftInput(findViewById(R.id.webView1),
InputMethodManager.SHOW_FORCED);
}
}
onCreate Code
WebView wv = (WebView) findViewById(R.id.webView1);
wv.addJavascriptInterface(new WebAppInterface(this), "Android");
WebSettings webSettings = wv.getSettings();
webSettings.setJavaScriptEnabled(true);
wv.loadUrl("file:///android_asset/index.html");
Its working fine on my side I am using Nexus5. Although cursor won't showed up in screenshot but it is blinking when I run the app.
