Question

我正在制作一个网球得分应用程序，我有两个问题：

如何重置点击次数，因为如果我点击5次或更多次点击它就不再有用了。

如果得分为“40 - 40”，我怎样才能让得分之一显示出“优势”。

public class tennis extends Activity {

// Private member field to keep track of the count
int Count = 0;


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

    //Left Counter//
    final TextView countTextView = (TextView) findViewById(R.id.TextViewCount);
    final Button countButton = (Button) findViewById(R.id.ButtonCount);

    countButton.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            Count++;
            if (Count==1){
            countTextView.setText("15");}
            else
            if (Count== 2){
            countTextView.setText("30");}
            else
            if (Count==3){
            countTextView.setText("40");}
            else
            if (Count==4){
            countTextView.setText("A");}
            else {
            countTextView.setText("0");}
        };
    });
}
}

Answer 1

您可以尝试使用getText（）来查看是否有优势，或者只使用更多Count if / else东西。

       public void onClick(View v) {
    CountA++;
    if (CountA==1){
    countATextView.setText("15");}
    else
    if (CountA== 2){
    countATextView.setText("30");}
    else
    if (CountA==3){
    countATextView.setText("40");}
    else
    if (CountA==4){
      //Checks if BScore was Advantage initially and if AScore is 40
      if (CountB==3 && ATextView.getText() =="40" && BTextView.getText() =="A")
      {
        countBTextView.setText("40");
        CountA--
      }
      //Else if BScore is not A, and AScore is 40, set AScore to A
      elseif(CountB==3 && BTextView.getText() !="A")
      {
        countATextView.setText("A");
        CountA--
      }
      //Otherwise just reset score
      else
      {
        countATextView.setText("0");
        CountA = 0;
      }
};

Answer 2

重置点击次数的两个选项。检查Count＆gt; 5并在功能结束时将其重置为0或使用mod 5.我不确定你是如何跟踪那里的得分，但是当你更新得分并且给予优势时你可以检查40-40得分球员。
