如何在android中制作单选按钮？

我是一个android编程的新手，正在尝试创建一个单选按钮组

比如说,， 在我的应用程序中有3个按钮，当一个按钮被点击时，其他的按钮应该被解锁

我怎样才能有效地做到这一点

给我一个提示：（比如我应该使用什么类或方法？

你的意思是：

Button myButton1;
Button myButton2;
Button myButton3;

myButton1 = (Button) findViewById(R.id.button1);

myButton1.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {

        myButton1.setBackgroundColor(Color.Green); 
        myButton2.setBackgroundColor(Color.Gray); 
        myButton3.setBackgroundColor(Color.Gray); 
    }
});

myButton2 = (Button) findViewById(R.id.button1);

myButton2.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {

        myButton2.setBackgroundColor(Color.Green); 
        myButton1.setBackgroundColor(Color.Gray); 
        myButton3.setBackgroundColor(Color.Gray); 
    }
});

myButton3 = (Button) findViewById(R.id.button1);

myButton3.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {

        myButton3.setBackgroundColor(Color.Green); 
        myButton1.setBackgroundColor(Color.Gray); 
        myButton22.setBackgroundColor(Color.Gray); 
    }
});

我也不是经验丰富的开发人员。但答案取决于你想要实现什么。你可以使用andruboy提到的单选组，但就个人而言，我不喜欢单选按钮的外观，所以我经常使用如下按钮创建我自己的单选组

myButton1 = (ImageButton) findViewById(R.id.button1);
myBytton2 =  (ImageButton) findViewById(R.id.button2);
myBytton3 =  (ImageButton) findViewById(R.id.button3);
// this variable indicate which button was clicked as last, u can use this info for next action
int whichButtonClicked = 1;

myButton1.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
     whichButtonClicked = 1;
     myButton1.setBackgroundColor(Color.Red);
     myButton2.setBackgroundColor(Color.Gray);
     myButton3.setBackgroundColor(Color.Gray);

}

});
myButton2.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
     whichButtonClicked = 2;
     myButton1.setBackgroundColor(Color.Gray);
     myButton2.setBackgroundColor(Color.Red);
     myButton3.setBackgroundColor(Color.Gray);

}

});

对于第三个按钮，代码看起来类似

我从头开始写的，如果有什么东西不起作用，给我一个词，我会在以后测试它

我希望这个答案能帮助你满足你的需求
