java - 添加计时器并卡住应用程序(android studio)

Question

我正在 android studio 上写一个测验应用程序，现在，我的目标是为每个错误答案添加一个时间惩罚，意味着，如果用户回答错误，他将不得不等待，比如说 10 秒，直到他能够再次回答，在这 10 秒内，应用程序将卡住，用户将不得不等待。

我想显示剩余时间。

定时器应该插入到这部分代码中:

    butNext.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            RadioGroup grp = (RadioGroup) findViewById(R.id.radioGroup1);
            RadioButton answer = (RadioButton) findViewById(grp.getCheckedRadioButtonId());
            Log.d("yourans", currentQ.getANSWER() + " " + answer.getText());
            if (currentQ.getANSWER().equals(answer.getText())) {//bad equal to
                score++;
                Log.d("good answer", "Your score" + score);
            }else {
                Log.d("bad answer", "Your score" + score);
               ***//the time should be implemented here***
            }
            if (qid < 7) {
                currentQ = quesList.get(qid);
                setQuestionView();
            } else {
                Intent intent = new Intent(Questionsctivity.this, ResultActivity.class);
                Bundle b = new Bundle();
                b.putInt("score", score); //Your score
                intent.putExtras(b); //Put your score to your next Intent
                startActivity(intent);
                finish();
            }
        }
    });

谢谢

试试这个:

new Handler().postDelayed(new Runnable() {
                public void run() {
                // code called after 5 seconds...
                }
            }, 5 * 1000);
