Hey!

You can inject a script in the WebScreenlet to detect the click event and then communicate with the native part to perform some action.

You have to create a script in js that handles the click event and call the method 
window.Screens.postMessage('clicked', <data-that-will-be-received-in-native>)</data-that-will-be-received-in-native>


After doing this, you will have to implement the WebScreenlet listener in your activity. You will receive the message from js in the method onScriptMessageHandler. In that method you can perform the action you need with the data received

You have documentation about the webScreenlet here and here

I hope it helps emoticon

Injecting a script in both iOS and Android works only first time when page loaded. If the page refreshed than it doesn't work. Here I have shown an example in this video link.  https://drive.google.com/open?id=1Q0fCWZ3U2naRHEGhXbrapmLcNyqA7TXN

 

Thanks

What version of Liferay Screens are you using? This was fixed in the latest version (4.0.0)

Can you try that version and check if the issue still exists?

Hi!

I've just saw the video, for keeping a script while navigation throught SPA, you have an utility function in the Screens global object, basically you have to pass the function that you need to preserver when SPA navigation happens.

 

You have to do this in your case: 

window.Screens.addScreensScript(modifyItem);
