会发生什么应用程序记录所有的toggleButton id，当用户单击播放按钮时，应用程序会生成一个随机数，然后将其与选定的数字匹配，如果匹配则用户获胜......

游戏中切换按钮的总数设置为 12

请帮忙

我怎样才能获得选定的toggleButtons id以及如何将它们与随机数匹配请帮忙

为按钮添加一个点击监听器，在那里您应该能够获取在按下按钮时已检查的切换按钮的 ID：

@Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

            textView1 = (TextView) findViewById(R.id.textView1);
            textView2 = (TextView) findViewById(R.id.textView2);
            button1 = (Button) findViewById(R.id.button1);

            ToggleButton cb = null;

            for (int i = 0; i < 12; i++) {
                cb = new ToggleButton(this);
                cb.setText(Integer.toString(i));
                cb.setTextOn(Integer.toString(i));
                cb.setTextOff(Integer.toString(i));
                cb.setBackgroundResource(R.drawable.check);
                cb.setOnClickListener(this);
                cb.setId(i);
                registerForContextMenu(cb);
                mToggleButtons.add(cb);
            }

            GridView gridView = (GridView) findViewById(R.id.gridview);
            gridView.setAdapter(new CustomAdapter(mToggleButtons));
            gridView.setOnItemClickListener(new OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View v,
                        int position, long id) {

                }
            });

            button1.setOnClickListener(new OnClickListener() {

          @Override
          public void onClick(View v) {

                 int random = (new Random()).nextInt(12);

                 ArrayList<Integer> positive_IDs = new ArrayList<Integer>();
                 for(int i = 0; i < mToggleButtons; i++){
                     ToggleButton b = mToggleButtons.get(i);
                     if(b.isChecked()){
                    positive_IDs.add(b.getId());    
                     } 
                 }

                 // do whatever needed with the positive_IDs, for example:

                 if(positive_IDs.contains(random)){
                     // doAction();
                 }       
          }
           });


        }
