Question

public void allButtonChoice(){
Button[] multiChoice = new Button[3];
multiChoice = new Button[]{choiceButton1,choiceButton2,choiceButton3,choiceButton4};

//to output shuffled array in an randomized order.
//Random number generator.

Random generateMultiChoice = new Random();

for(int i = 0; i < multiChoice.length; i++){
    int randomPosition = generateMultiChoice.nextInt(multiChoice.length);
    Button temp = multiChoice[i];
    multiChoice[i] = multiChoice[randomPosition];
    multiChoice[randomPosition] = temp;
}

//set the positions to the buttons in order
choiceButton1.setX(10f);
choiceButton1.setY(10f);
choiceButton2.setX(10f);
choiceButton2.setY(10f);
choiceButton3.setX(10f);
choiceButton3.setY(12f);
choiceButton4.setX(10f);
choiceButton4.setY(12f);
}

如何为choiceButton1，choiceButton2，choiceButton3和choiceButton4分配变量？是否可以使用一个变量来保存包含setX和setY数据的四个按钮？
