Question

我创建了一个简单的数学游戏，我想根据正确的问题答案更新我的进度条。示例：每次我正确回答问题时，进度条应该达到10％等等。

public class QuestionActivity extends Activity 
    {
    List<Question> quesList;
    int score = 0;
    int qid = 0;

    Question currentQ;
    TextView txtQuestion, times, scored;
    Button button1, button2, button3;
    ProgressBar pb;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    QuizHelper db = new QuizHelper(this);  // my question bank class
    quesList = db.getAllQuestions();  // this will fetch all quetonall               

    questions
    currentQ = quesList.get(qid); // the current question

    // the textview in which the question will be displayed
    txtQuestion = (TextView) findViewById(R.id.txtQuestion);

    //the progress bar in which progress will be displayed
    pb = (ProgressBar)findViewById(R.id.progressBar);

    // the three buttons,
    // the idea is to set the text of three buttons with the options from  

    question bank
    button1 = (Button) findViewById(R.id.button1);
    button2 = (Button) findViewById(R.id.button2);
    button3 = (Button) findViewById(R.id.button3);

    // the textview in which score will be displayed
    scored = (TextView) findViewById(R.id.score);

    // the timer
    times = (TextView) findViewById(R.id.timers);

    // method which will set the things up for our game
    setQuestionView();
    times.setText("00:02:00");

    // A timer of 60 seconds to play for, with an interval of 1 second (1000   

    milliseconds)
    CounterClass timer = new CounterClass(60000, 1000);
    timer.start();

    // button click listeners
    button1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // passing the button text to other method
            // to check whether the answer is correct or not
            // same for all three buttons
            getAnswer(button1.getText().toString());
            setProgressBar();
        }
    });

    button2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            getAnswer(button2.getText().toString());
            setProgressBar();
        }
    });

    button3.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            getAnswer(button3.getText().toString());
            setProgressBar();
        }
    });
}

public void getAnswer(String AnswerString) {
    if (currentQ.getAnswer().equals(AnswerString)) {

        // if conditions matches increase the int (score) by 1
        // and set the text of the score view
        score++;
        scored.setText("Score : " + score);
    } else {
        // if unlucky start activity and finish the game

        Intent intent = new Intent(QuestionActivity.this,
                ResultActivity.class);

        // passing the int value
        Bundle b = new Bundle();
        b.putInt("score", score); // Your score
        intent.putExtras(b); // Put your score to your next
        startActivity(intent);
        finish();
    }
    if (qid < 20) {
        // if questions are not over then do this
        currentQ = quesList.get(qid);
        setQuestionView();
    } else {
        // if over do this
        Intent intent = new Intent(QuestionActivity.this,
                ResultActivity.class);
        Bundle b = new Bundle();
        b.putInt("score", score); // Your score
        intent.putExtras(b); // Put your score to your next
        startActivity(intent);
        finish();
    }
}

    txtQuestion.setText(currentQ.getQuestion());
    button1.setText(currentQ.getOptionA());
    button2.setText(currentQ.getOptionB());
    button3.setText(currentQ.getOptionC());

    qid++;
}

private void setProgressBar()
{

}

}

Answer 1

private void setProgressBar()
 {
   int progress=pb.getProgress();

 if(progress<100)
    pb.setProgress(progress+10)


 }

这应该可以解决问题，每次调用setProgressBar()方法

时，它都会增加10点

Answer 2

第一：设置进度条限制

pb.setMax（Total Quest * 10）

稍后

每个Correct Answer Inc得分++;

private void setProgressBar()
 {
    pb.setProgress(score*10);
 }

进度条基于正确的答案
