Question

这是我在Android Studio中制作的小应用的来源。当我调用这个函数时，它假设将dog，cat和parrot相互比较，然后将int dogCounter增加为5.当我运行该函数时，它不会更新分数。

dogCounter= 0;
catCounter = 0;

//check boxes
cutestCheckBoxDog = (CheckBox)findViewById(R.id.CheckboxCutestDog);
cutestCheckBoxCat = (CheckBox)findViewById(R.id.CheckboxCutestCat);
cutestCheckBoxParrot =(CheckBox)findViewById(R.id.CheckboxCutestParrot);

//call methods
processCutest(cutestCheckBoxDog, cutestCheckBoxCat, cutestCheckBoxParrot);

showResultButton= (Button)findViewById(R.id.showResults);
showResultButton.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {

          Toast.makeText(getApplicationContext(),catCounter +  " " + dogCounter, Toast.LENGTH_LONG).show();

public void processCutest(CheckBox dog, CheckBox cat, CheckBox parrot){


    if (dog.isChecked() && !cat.isChecked() && !parrot.isChecked()){
        dogCounter += 5;
    }else if (cat.isChecked() && !dog.isChecked() && !parrot.isChecked()){
        catCounter += 5;
    } else{
        //nobody gets points
    }
}

编辑：抱歉组织不好。还是很新的，关于它的指针也会很好。

我认为你只需要改变你的processCutest调用，使其进入onClick方法，但是在toast.makeText调用之前。像这样：

showResultButton= (Button)findViewById(R.id.showResults);
showResultButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        processCutest(cutestCheckBoxDog, cutestCheckBoxCat, cutestCheckBoxParrot);

        Toast.makeText(getApplicationContext(),catCounter +  " " + dogCounter, Toast.LENGTH_LONG).show();

我假设实际的复选框是在别处定义的。你的复选框出现了吗？如果是这样，您可能还想将processDrool和processCanine调用放在那里。

复选框和if-else语句
