当发生第二次点击按钮时，如何更改指定以前点击的图像按钮的视图

Question

I have doubt in when I click the 2nd time image button, I want to change the both button image view in simultaneously.

Example: 1. first time press the button 1 and change already the first time image view. (get work) 2. second time press the other button 2 and I want change image view for the both button 1 and 2 in simultaneously. But I can only get the ibutton as variable signal to change the button 2 image view and button 1 can't get.

Question: 1. How do I change the button image view for button 1 when I click the button 2? 2. How do I can keep the button variable in array?

My code like this:

public class CheckersTest extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.welcome);

        final ImageView iv_new_game = (ImageView) findViewById(R.id.new_game);
        iv_new_game.setOnClickListener(welcome_listener);
    }

    OnClickListener welcome_listener = new View.OnClickListener() {

        public void onClick(View v) {
            final ImageView iv = (ImageView) v;
            if (iv.getId() == R.id.new_game) {
                setContentView(R.layout.checkers_board);

            final ImageButton b2 = (ImageButton) findViewById(R.id.imageButton2);
            final ImageButton b4 = (ImageButton) findViewById(R.id.imageButton4);
            final ImageButton b6 = (ImageButton) findViewById(R.id.imageButton6);

// set the OnClickListeners.

                b2.setOnClickListener(button_listener);
                b4.setOnClickListener(button_listener);
                b6.setOnClickListener(button_listener);

// Re-enable the Click-able property of buttons.

                b2.setClickable(true);
                b4.setClickable(true);
                b6.setClickable(true);
              }
        };
    };


 OnClickListener button_listener = new View.OnClickListener() {

        public void onClick(View v) {
            ImageButton ibutton = (ImageButton) v;

        ibutton.setImageResource(R.drawable.green_bol);

       }
};

在第二个Button的onclick方法中，获取第一个按钮的实例并设置图像。
