Android 一群广播电台的普通听众

我有大约60个广播组需要注册一个听众。目前我是这样做的：

    RadioGroup rg1 = (RadioGroup) getView().findViewById(R.id.rdoGrp1);
    rg1.setOnCheckedChangeListener(this);
    rg1 = (RadioGroup) getView().findViewById(R.id.rdoGrp2);
    rg1.setOnCheckedChangeListener(this);
    rg1 = (RadioGroup) getView().findViewById(R.id.rdoGrp3);
    rg1.setOnCheckedChangeListener(this);

等等，60个广播集团。有没有一种方法可以将片段上的所有无线电组设置为在一个或两个语句中注册到一个公共侦听器，而不必键入这么多代码？谢谢

一个简单的解决方案是在您的活动或您正在编写的任何类中创建一个方法，如下所示：

private void registerListenerToGroup(int groupId) {
    RadioGroup rg = (RadioGroup) getView().findViewById(groupId);
    rg.setOnCheckedChangeListener(this);
}

registerListenerToGroup(R.id.rdoGrp1);
registerListenerToGroup(R.id.rdoGrp2);
registerListenerToGroup(R.id.rdoGrp3);
//etc.

ViewGroup parent = (ViewGroup) findViewById(R.id.ParentViewId);
for (int i = 0; i < parent.getChildCount(); i++) {
    View currentView = parent.getChildAt(i);
    if (currentView instanceof RadioGroup) {
        ((RadioGroup) currentView).setOnCheckedChangeListener(this);
    }
}

然后，从代码中调用此方法，如下所示：

private void registerListenerToGroup(int groupId) {
    RadioGroup rg = (RadioGroup) getView().findViewById(groupId);
    rg.setOnCheckedChangeListener(this);
}

registerListenerToGroup(R.id.rdoGrp1);
registerListenerToGroup(R.id.rdoGrp2);
registerListenerToGroup(R.id.rdoGrp3);
//etc.

ViewGroup parent = (ViewGroup) findViewById(R.id.ParentViewId);
for (int i = 0; i < parent.getChildCount(); i++) {
    View currentView = parent.getChildAt(i);
    if (currentView instanceof RadioGroup) {
        ((RadioGroup) currentView).setOnCheckedChangeListener(this);
    }
}

如果所有RadioGroup元素共享同一父元素，则可以使用和进行迭代。大概是这样的：

private void registerListenerToGroup(int groupId) {
    RadioGroup rg = (RadioGroup) getView().findViewById(groupId);
    rg.setOnCheckedChangeListener(this);
}

registerListenerToGroup(R.id.rdoGrp1);
registerListenerToGroup(R.id.rdoGrp2);
registerListenerToGroup(R.id.rdoGrp3);
//etc.

ViewGroup parent = (ViewGroup) findViewById(R.id.ParentViewId);
for (int i = 0; i < parent.getChildCount(); i++) {
    View currentView = parent.getChildAt(i);
    if (currentView instanceof RadioGroup) {
        ((RadioGroup) currentView).setOnCheckedChangeListener(this);
    }
}

ViewGroup parent=（ViewGroup）findviewbyd（R.id.ParentViewId）；
对于（int i=0；i

谢谢。好主意！我将尝试为所有单选按钮创建一个公共父按钮。谢谢。好主意！我将尝试为所有单选按钮创建一个公共父按钮。
