Question

Is it possible if I have 5 (or more buttons) to change activity when all of then are pressed. Like when last button is pressed my app should change activity. And it shouldn’t matter what button of those five is pressed last.

Any ideas? 🙂

Answer 1

Sure, create an array of booleans for each button:

boolean[] pressedButtons = new boolean[5];

In each of the listeners, when the button is pressed set the appropriate cell in the array to true, and then call such a method (abstract implementation):

private void startActivityIfReady() {
    boolean ready = true;
    for (boolean b : pressedButtons)
        ready = ready && b;
    if (ready) {
        // start your activity
    }
}
