java - 正确答案进度条

Question

我正在 android studio 中做一个小数学游戏，从第一级开始，玩家需要连续回答 10 个问题。我会计算分数，当玩家获得一定分数时，他们就会进入另一个级别。我想添加一个进度条，随着正确答案的进展。所以说，当玩家需要连续 10 个正确答案但只有 5 个时，它将被填充 50% 等。这是计算分数的代码:

  Button answerButton = (Button) findViewById(R.id.answerButton);
    answerButton.setOnClickListener(new View.OnClickListener(){
        @Override

        public void onClick(View v) {
            try{
                answerUser = Integer.parseInt(numberEdit.getText().toString());
            }
            catch (NumberFormatException e)
            {
                answerUser = 0;
                Toast.makeText(context,
                        "Error, masdaohfisahfi9aw",
                        Toast.LENGTH_SHORT).show();
            }
            if(answer == answerUser)
            {
                TextView Scores = (TextView) findViewById(R.id.scoreText);
                score ++;

                String String3 = String.valueOf(score);
                Scores.setText(String3);
                answerText.setText("Well done!");
                do {
                    Random rand = new Random();
                    Random rand1 = new Random();
                    number = rand.nextInt(10) + 1;
                    numbers1 = rand1.nextInt(10) + 1;
                    TextView number1 = (TextView) findViewById(R.id.number1);
                    TextView number2 = (TextView) findViewById(R.id.number2);

                    String String1 = String.valueOf(number);
                    String String2 = String.valueOf(numbers1);
                    number1.setText(String1);
                    number2.setText(String2);
                    answer = number + numbers1;
                    answerUser = 0;
                    numberEdit.setText("");

                }

                while(answer==answerUser);
                if(score == 10)
                {
                    alert();
                }
            }
            else
            {
                answerText.setText("Wrong");
                TextView Scores = (TextView) findViewById(R.id.scoreText);
                score = 0;
                String String3 = String.valueOf(score);
                Scores.setText(String3);
            }
        }

    });

在你的类(class):

ProgressBar progressBar

在你的 onCreate 中:

 progressBar = (ProgressBar) findViewById(R.id.answerProgress);
 progressBar.setMax(10);
 progressBar.setProgress(0);

然后在这部分代码中

 if(answer == answerUser)
            {
                TextView Scores = (TextView) findViewById(R.id.scoreText);
                score ++;
                progressBar.setProgress(score);
                ....
            } 

在 XML 中，指定您想要一个水平进度条，否则它将是圆形的:

<ProgressBar
    android:layout_width="match_parent"
    android:layout_height="50dp"
    style="@android:style/Widget.Holo.ProgressBar.Horizontal"
    android:id="@+id/answerProgress"
    />
