我正在尝试创建2行单选按钮,如下图所示。 但是当我直接把它放在上面时,我的无线电组就没有工作了 LinearLayout。

我是Android开发的新手。所以,如果有更好的选择。 欢迎他们

您可以创建2个无线电组并处理RadioButtonCliked事件中的所有内容 像那个例子

public void RadioButtonClicked(View view) {
    boolean checked = ((RadioButton) view).isChecked();

    switch(view.getId()) {
        case R.id.radioButton33: {  
            NameRadioGroup2.clearCheck();
            NameRadioGroup1.check(view.getId());
            break;
        }

        case R.id.radioButton40: {
            NameRadioGroup1.clearCheck();
            NameRadioGroup2.check(view.getId());          
            break;
        }
        {here implement cases for other radio buttons}
}



public void RadioButtonClicked(View view) {
    boolean checked = ((RadioButton) view).isChecked();
    if(ButtonFromRadioGroupOne(view.getId())
    {
       NameRadioGroup2.clearCheck();
       NameRadioGroup1.check(view.getId());
    }
    else
    {
       NameRadioGroup1.clearCheck();
       NameRadioGroup2.check(view.getId());
    }
}

private bool ButtonFromRadioGroupOne(int id)
{
    return id == R.id.radioButton33 || id == R.id.radioButton34 || id == R.id.radioButton35 || id == R.id.radioButton36 || id == R.id.radioButton37 || id == R.id.radioButton38 || id == R.id.radioButton39;
}

或者每个广播组可以有2个RadioButtonClicked事件。

public void RadioButtonClicked1(View view) {
    RadioButtonClicked(NameRadioGroup1, NameRadioGroup2, view);
}

public void RadioButtonClicked2(View view) {
    RadioButtonClicked(NameRadioGroup2, NameRadioGroup1, view);
}

public void RadioButtonClicked(RadioGroup selected, RadioGroup cleared, View view) {
    boolean checked = ((RadioButton) view).isChecked();
    cleared.clearCheck();
    selected.check(view.getId());
}

我修好了

首先,我创建了一个扩展方法,以便从视图中获取te子项

static class Extention
    {
        public static List<T> Childs<T>(this ViewGroup view) where T : View
        {
            List<T> childs = new List<T>();
            for (int i = 0; i < view.ChildCount; i++)
            {
                var selectedView = view.GetChildAt(i) as T;
                if (view != null)
                {
                    childs.Add(selectedView);
                }
            }
            return childs;
        }
    }

我在主要的

中添加了这段代码
LinearLayout Layout2 = FindViewById<LinearLayout>(Resource.Id.linearLayout2);
            LinearLayout Layout3 = FindViewById<LinearLayout>(Resource.Id.linearLayout3);
            Buttons = Layout2.Childs<RadioButton>();  
            Buttons.AddRange(Layout3.Childs<RadioButton>());
            foreach(RadioButton button in Buttons)
            {
                button.CheckedChange += RadioButton_Check;
            }

这是我的活动

 public bool InUse = false;
        private void RadioButton_Check(object sender, CompoundButton.CheckedChangeEventArgs e)
        {
            if (InUse) return;
            InUse = true;
            RadioButton Senderbutton = sender as RadioButton;
            foreach (RadioButton button in Buttons)
            {
                button.Checked = false;
            }
            Senderbutton.Checked = true;
            InUse = false;
        }
