App stop working after button click

Question

so I´m making an app with fragments and I want a sound on button click. Everything works except when I click on the button the app stop working. I put an onclick method named playAnother on the button. I think the problem might be there in .java file: I dont know what to do I´m total beginner. Have a nice day!

Answer 1

The method playAnother(View view) must be in your Activity, not in fragment.

OR

If you want to handle the button click in your fragment you can give your button an id:

<Button
  android:id="@+id/button"
  .
  .

And then in your fragment's onCreateView()

public View onCreateView(...) {
    // First we save the reference to the views of your fragment
    View view = inflater.inflate(R.layout.fragment_three, container, false);

    // Then we need to find the button-view
    Button button = (Button) view.findViewById(R.id.button);
    // And finally we can register OnClickListener for the button
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // Handle your button click here
        }
    });
    return view;
}
