我为乒乓球开发了一个得分计数器应用程序。 在其中，我已经为＆＃34;服务变更＆＃34; imgView。 但是，当快速按下分数按钮时，我会遇到问题，导致应用程序崩溃 ScoreActivity.java
public class ScoreActivity extends AppCompatActivity {
Button point1,point2;
int points1=0,points2=0;

ViewGroup trans;
TransitionSet set;
TextView score1,score2,duce,adv1,adv2,p1,p2;
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_score);
initComponents();
Fade fade = new Fade();
Slide slideR = new Slide(Gravity.END);
final Fade fadeout = new Fade(Fade.OUT);
set = new TransitionSet()
.addTransition(fade)
.addTransition(slideR);
set.addListener(new Transition.TransitionListener() {
int n =0;
@Override
public void onTransitionStart(Transition transition) {
n = 1;
}
@Override
public void onTransitionEnd(Transition transition) {
fadeout.setStartDelay(500);
TransitionManager.beginDelayedTransition(trans,fadeout);
serve.setVisibility(View.GONE);
}
@Override
public void onTransitionCancel(Transition transition) {
}
@Override

});
makeAllGone();
score1.setText("00");
score2.setText("00");
point1.setOnClickListener(new View.OnClickListener() {

score1.setText(scoreIncrement(points1));
points1++;
