與單選按鈕自定義列表視圖返回上setOnCheckedChangeListener

Question

我使用 custom listivew與已 buttonGroup每一行方含 5 radiobuttons

相同的id，

setOnCheckedChangeListener(new OnCheckedChangeListener() { 
    @Override 
    public void onCheckedChanged(RadioGroup group, int checkedId) { 
    int selectedId =viewHolder.radioGroup1.getCheckedRadioButtonId(); 
    } 
    } 

這methord selectedId總是返回我相同的值，所以我無法知道哪個單選按鈕選擇請大家幫忙，下面是我的代碼，

Answer 1

setOnCheckedChangeListener(new OnCheckedChangeListener() { 
    @Override 
    public void onCheckedChanged(RadioGroup group, int checkedId) { 
     switch(checkedId) 
    { 
    case R.id.rb1:// do what you wan there 
          break; 
    case R.id.rb2: 
          break; 

    } 
    } 
    } 

Answer 2

使用下面的代碼在你custom listview點擊的項偵聽

RadioButton radio = (RadioButton) arg1.findViewById(your id);
