Radiobutton檢查點擊列表視圖onclicklistener

我使用的是帶有textview和Radiobutton的listview。我想實現單選按鈕獲取檢查ListView onItemClickListener，我該怎麼做？這是我的主要活動。我試圖做到這一點，但當我點擊listview複選框檢查多個選擇，當我滾動列表單選按鈕框損失其狀態。Radiobutton檢查點擊列表視圖onclicklistener

其中是checkBox？ – Opiatefuchs

抱歉，我的錯誤是單選按鈕沒有複選框抱歉。 – user3470118

您可以設置onclickListner在costcode_lv_model

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="vertical" android:layout_width="match_parent" 
android:layout_height="match_parent"> 


<RadioButton 
    android:id="@+id/costcode_rb" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    ........

的父視圖給id來此的RelativeLayout並在Cli上申請ckListner它。

in onClick方法檢查那邊的複選框。

holder.costcode_relative.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(final View view) { 

      // code here to set the radioButton checked 
      } 
     });

您的LitModel需要有一個屬性來保存複選框的狀態。

如：

public class LitModel{ 
    private boolean state; 

    public boolean isState() { 
     return state; 
    } 

    public void setState(boolean state) { 
     this.state = state; 
    } 
}

複選框來設置LitModel的狀態。

holder.costcode_rb.setChecked(litModels.isState());

當您想要更改狀態，更改LitModel的狀態並刷新。

litModels.setState(true); 
notifyDataSetChanged();
