java - 如何创建禁用其他按钮的功能

Question

我正在创建一个问答游戏，可以通过选择答案按钮获取用户答案。我想创建一个功能，当用户点击按钮作为答案时禁用其他按钮(答案选择)。目前，当用户连续按下多个按钮时，答案(点击的答案)将用作下一个问题的答案，具体取决于点击的次数。我曾尝试放置一个 boolean 标志来禁用其他按钮，但它将无法转到下一个问题。

这是我的按钮代码。

public void onClick(View v) {
    switch (v.getId()) {
        case (R.id.choice1_Button) :
            if (choice1.getText().equals(answer)) {
                correct = 1;
                sound(correct);
                score += 10;
                Toast.makeText(this, "Brilliant! The answer is correct", Toast.LENGTH_SHORT).show();
                scoreboard(score);
                getNextQuestion(counter);
            }else {
                correct = 0;
                sound(correct);
                Toast.makeText(this, "Nice try. The correct answer is "+answer, Toast.LENGTH_SHORT).show();
                if (score > 0) {
                    score = score - 3;
                }
                if (score < 0){
                    score = 0;
                }
                scoreboard(score);
                getNextQuestion(counter);
            }
            break;
        case (R.id.choice2_Button) :
            if (choice2.getText().equals(answer)) {
                correct = 1;
                sound(correct);
                score += 10;
                Toast.makeText(this, "Brilliant! The answer is correct", Toast.LENGTH_SHORT).show();
                scoreboard(score);
                getNextQuestion(counter);
            }else {
                correct = 0;
                sound(correct);
                Toast.makeText(this, "Nice try. The correct answer is "+answer, Toast.LENGTH_SHORT).show();
                if (score > 0) {
                    score = score - 3;
                }
                if (score < 0){
                    score = 0;
                }
                scoreboard(score);
                getNextQuestion(counter);
            }
            break;
        case (R.id.choice3_Button) :
            if (choice3.getText().equals(answer)) {
                correct = 1;
                sound(correct);
                score += 10;
                Toast.makeText(this, "Brilliant! The answer is correct", Toast.LENGTH_SHORT).show();
                scoreboard(score);
                getNextQuestion(counter);
            }else {
                correct = 0;
                sound(correct);
                Toast.makeText(this, "Nice try. The correct answer is "+answer, Toast.LENGTH_SHORT).show();
                if (score > 0) {
                    score = score - 3;
                }
                if (score < 0){
                    score = 0;
                }
                scoreboard(score);
                getNextQuestion(counter);
            }
            break;
    }
}

这是我的 getNextQuestion 方法

private void getNextQuestion(final int i) {
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            if (counter < 6) {
                setQuestion();
            }else {
                // if over 5 do this
                Intent intent = new Intent(Level6.this, NextLevel.class);
                Bundle a = new Bundle();
                a.putInt("score", score);
                a.putInt("level", 6);
                intent.putExtras(a);
                startActivity(intent);
                finish();
            }
        }
    },500);
}

这是我的 setQuestion() 方法

private void setQuestion() {
    emotion_View.setImageResource(questionsLib.getQuestions(counter));
    choice1.setText(questionsLib.getOptions1(counter));
    choice2.setText(questionsLib.getOptions2(counter));
    choice3.setText(questionsLib.getOptions3(counter));
    answer = questionsLib.getCorrectAnswer(counter);
    counter++;

}

Answer 1

制作禁用按钮组的方法，如下所示:

private void setQuestion(Boolean enable) {
    choice1.setEnabled(enable);
    choice2.setEnabled(enable);
    choice3.setEnabled(enable);
}

1. 然后在getNextQuestion之前执行此方法来设置按钮禁用(setQuestion(false))
2. 设置下一个问题后，通过处理程序中的方法 (setQuestion(true)) 启用按钮。

或者您可以在 getNextQuestion 方法中全部设置:

private void getNextQuestion(final int i) {
    setQuestion(false); //disable buttons
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            if (counter < 6) {
                setQuestion();
            }else {
                // if over 5 do this
                Intent intent = new Intent(Level6.this, NextLevel.class);
                Bundle a = new Bundle();
                a.putInt("score", score);
                a.putInt("level", 6);
                intent.putExtras(a);
                startActivity(intent);
                setQuestion(true); //enable buttons
                finish();
            }
        }
    },500);
}
