NOTE: Assumption is that MainActivity is the first Activity and ToggleActivity is the second Activity (based on comments below)

Your button could go back to the previous Activity and tell it to take a screenshot of itself. In ToggleActivity.onClick() add something like this:

Intent goBackIntent = new Intent(this, MainActivity.class);

intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

intent.putExtra("screenshot", true);

startActivity(intent);

finish();

Adding the flag FLAG_ACTIVITY_SINGLE_TOP ensures that Android uses the existing instance of the previous Activity and doesn't start a new instance.

In MainActivity you override onNewIntent():

@Override

public void onNewIntent(Intent intent) {

    if (intent.hasExtra("screenshot") {

        // Add code to take screeenshot here

    }

}
