Java – binding methods to buttons in Android

There is a button in my layout, which contains the following attributes: Android: onclick = "nextq". In my java code, there are the following methods:

public int nextQ()
{
    // do stuff here
    return answer;
}

The answer is an integer Just click this button and the application will close Do you know why it breaks?

Solution

If you have Android: onclick = "nextq", your context (usually your activity) must have a method that signs public void nextq (view view) See docs on the onclick attribute
