How to call javascript function from java?

I have a native android library, Which expects a java function which works as an event. But in my nativescript plugin, I want to pass javascript function to the library so that library events are fired in javascript runtime.

Solution

  • If your Java method expects an interface for callback functions, it's already covered in the NativeScript docs.

    Java

    button.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        // Perform action on click
    }
});

    JavaScript

    button.setOnClickListener(new android.view.View.OnClickListener({
    onClick: function() {
        // Perform action on click
    }
}));
