Android API模拟器与设备

Question

I am developing a game My code works fine in the 4.0 Emulator but not on my Samsung galaxy W with 2.3.6 I did't use code that isn't suitable with the device version but how ever on my device nothing moves but there isn't even an error in logcat or sth.

MainActivity :

public class ControlsActivity extends Activity implements OnTouchListener{

    Button up;
    Button down;
    Button left;
    Button right;

    String view;

    static boolean touch=false;


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.main);

        up = (Button) findViewById(R.id.up);
        up.setOnTouchListener(this);

        down = (Button) findViewById(R.id.down);
        down.setOnTouchListener(this);

        left = (Button) findViewById(R.id.left);
        left.setOnTouchListener(this);

       right = (Button) findViewById(R.id.right);
        right.setOnTouchListener(this);



    }


    @Override
    public boolean onTouch(View v, MotionEvent event) {
        /*
        view = v.toString();
        if (ControlsActivity.view == "up" && ControlsActivity.touch == true)
        {
            ph--;
        }
        if (ControlsActivity.view == "down" && ControlsActivity.touch == true)
        {
            ph++;
        }
        if (ControlsActivity.view == "left" && ControlsActivity.touch == true)
        {
            pw--;
        }
        if (ControlsActivity.view == "right" && ControlsActivity.touch == true)
        {
            pw++;
        }
        */
        if(event.toString().contains("action=ACTION_UP"))
        {
            touch = false; 
        }

        if(event.toString().contains("action=ACTION_DOWN"))
        {

            touch = true;
        }


        return touch;

    }



}

            paint.setColor(Color.GREEN);
