java - How to disable interaction between buttons of the same layout?

Question

I have two sets of layouts, populated with buttons. Is there a way to disable any interaction between buttons of the same layout? I just need nothing to happen when I click one button and then the other from the same layout. I tagged each button with " and ", for buttons that belongs to upper and lower layouts. I have 5 of each kind. I have some interaction beetwen buttons of oposite layouts and that's working fine (actually interaction works fine between any two given buttons and that's bad), but I don't want that interaction between buttons of the same layout.

Here's my game class, not all of it, just important parts. Also, I've removed code for rest of the buttons, only left for 4 buttons, 2 for each layout, to save some space here. I import some text from sqlite database, and randomly set it to my buttons.

final OnClickListener clickListener = new OnClickListener() {

            private Button buttonClicked;

            public void onClick(View v) {


                Button button = (Button) v;
                button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x003333));

                if (buttonClicked == null) {
                    // first button is clicked
                    buttonClicked = button;
                } else {
                    // second button is clicked
                    if (buttonClicked.getTag().equals(button.getTag())) {
                        button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x66FF33));
                        buttonClicked.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x66FF33));
                      buttonClicked.setEnabled(false);
                        button.setEnabled(false);
                    } else {
                        buttonClicked.setEnabled(false);
                        buttonClicked.setTextColor(Color.GRAY);
                        buttonClicked.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0xFFCC99));
                        button.getBackground().clearColorFilter();
                    }
                    buttonClicked = null;

            }
     };




    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.game);

        a1 = (Button) findViewById(R.id.bA1);

        nextQuestion();
        }

        public void nextQuestion() {


        TestAdapter mDbHelper = new TestAdapter(this);
        mDbHelper.createDatabase();

        try{ 

            mDbHelper.open();

            Cursor c = mDbHelper.getTestData(generateWhereClause());

Answer 1

You can use the getParent method and compare the parents of both views. If the parent is the same, then the buttons are in the same layout and nothing should happen.

Change your else:

} else {
    // second button is clicked

... to an else if:

// only do stuff if buttons are in different layouts
} else if (button.getParent () != buttonClicked.getParent()) {
     // second button is clicked
