Question

使用我的第一款Android应用程序Cat Calculator。在猫发出咕噜声之后，计算工作正常，但如果它想要猫薄荷或花哨的盛宴，它会再次从最终的“Else”声明中获得调试错误，而不是猫咬或忽略你。

提供完整的代码，但错误很可能是在最后10行......

感谢您提供的任何帮助。 -Michael

    /** Called when the user clicks the CatCalculator button */
public void doCalculation(View view) {
    TextView homeAnswerView = (TextView) findViewById(R.id.homeAnswerView);
    TextView catActivityView = (TextView) findViewById(R.id.catActivityView);
    Random randomcatmood = new Random();
    double catmood = randomcatmood.nextDouble();

     if (catActivityView.getText().equals("cat calculator is sleeping on calculator")) {
         if (catmood <= 0.33) {
             catActivityView.setText("cat calculator starts purring");
         } else if (catmood <= 0.66) {
             catActivityView.setText("cat calculator wants fancy feast");
         } else {
             catActivityView.setText("cat calculator wants a catnip toy");
         }
     } else if (catActivityView.getText().equals("cat calculator starts purring")) {
        int answerInt;
        String answer;
        EditText numberOne = (EditText) findViewById(R.id.number1);
        EditText numberTwo = (EditText) findViewById(R.id.number2);
        int numberOnee = Integer.parseInt(numberOne.getText().toString());
        int numberTwoo = Integer.parseInt(numberTwo.getText().toString());
        answerInt = numberOnee * numberTwoo;
        answer = Integer.toString(answerInt);
        homeAnswerView.setText(answer);
    } else if (catActivityView.equals("cat calculator wants fancy feast")) {
        catActivityView.setText("cat calculator bites you for petting it now!");
    } else if (catActivityView.equals("cat calculator wants a catnip toy")) {
        catActivityView.setText("cat calculator bites you for petting it now!");
    } else if (catActivityView.equals("cat calculator bites you for petting it now!")) {
        catActivityView.setText("cat calculator ignores you");
    } else if (catActivityView.equals("cat calculator ignores you")) {
    } else {
        catActivityView.setText("debug: this should never happen");
    }
}

Answer 1

你在后面的行中遗漏了一堆getText()。

代码

catActivityView.equals("cat calculator wants fancy feast")

将TextView与您提供的String进行比较，而不是TextView的内容。你想要这样的东西：

catActivityView.getText().equals("cat calculator wants fancy feast")

你的前两个条件是正确的。这两个之后的所有人都缺少getText()。

Android Else-If，总是点击Else对于需要猫薄荷的猫计算器
