检查以下代码..它对我来说工作正常，

   public class ProjjActivity extends Activity {

    TextView txtview;
    float X,Y;

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

        txtview = (TextView) findViewById(R.id.tt);

    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        // TODO Auto-generated method stub

        X = event.getX();
        Y = event.getY();

        txtview.setText("X: "+X+", Y: "+Y);
        return super.onTouchEvent(event);
    }
}

希望这对你有帮助......!
