libgdx actor touchHandling

问题

I am currently experience some funny issue with touchHandling on LibGdx . My code is as follows:-

testCount=0;
ThisButton.addListener(new InputListener() {
public boolean touchDown (InputEvent event, float x, float y, int pointer, int button) {
    testCount++;
    gameLog("touchDown - testCount: " + testCount);
    return true;
}
public void touchUp (InputEvent event, float x, float y, int pointer, int button) {
    testCount++;
    gameLog("touchUp - testCount: " + testCount);
}

});

Theoretically, testCount should only return 2 (1 for touchDown, and 1 for touchUp) when the actor are touched. However, my LogCat output returns multiple calls on single tapped.

GreatGame: GameScreen: touchDown - testCount: 1
GreatGame: GameScreen: touchDown - testCount: 2
.
.
.
GreatGame: GameScreen: touchDown - testCount: 177
GreatGame: GameScreen: touchDown - testCount: 178
GreatGame: GameScreen: touchUp - testCount: 179
GreatGame: GameScreen: touchUp - testCount: 180
.
.
.
GreatGame: GameScreen: touchUp - testCount: 355
GreatGame: GameScreen: touchUp - testCount: 356

I am not sure where I went wrong.

Thank you very much and your help is much appreciated.
