[FIXED] Android Studio programmatically check a Checkbox and call its OnCheckedChange

Issue

Can I programmatically check a checkbox and make it call whatever it is coded to do once checked or unchecked?

For example, if I have a checkbox like this

    checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if(isChecked) {
                Toast.makeText(getContext(), "You checked the checkbox!", Toast.LENGTH_SHORT).show();
            }
            else {
                Toast.makeText(getContext(), "You unchecked the checkbox!", Toast.LENGTH_SHORT).show();
            }
        }
    });

And then would've called

checkBox.setChecked(true);

my checkbox would appear checked but it wouldnt make the toast.

Solution

You can do any of the following
1. Create the listener object separate and call it manually when you call setChecked
2. Extract the method for implementation of onCheckedChanged and call it manually on your change.
