スピナーチェックボックスボックスの状態が偽の取得と

Question

1. アダプタを更新していない私は、カスタムと1 CheckBoxとしています。私はアダプタを介してスピナーにアイテムを追加しています。チェックボックスをもう一度チェックすると、チェックが外されるか、またはチェックされたポジションに変更が加えられました。

2. 私はスピナーで選択した項目がEditTextに表示する必要があり、これまで何の両方Arrayからすなわちproduct_30またはproduct_80​​

3. から来るデータから2 Arrayを持っています。

コード

配列：

<string-array name="product_2_30"> 

     <item>A</item> 
     <item>B</item> 
     <item>C</item> 
     <item>D</item> 
     <item>E</item> 
     <item>N</item> 
</string-array> 

<string-array name="product_2_80">   
     <item>A1</item> 
     <item>B2</item> 
     <item>C3</item> 
     <item>D4</item> 
     <item>F5</item> 
     <item>NN</item> 
</string-array>

Answer 1

。あなたのリストの値を更新しているときにそのは間違って取得

Answer 2

チェックボックスは、（最終的に）ビューを拡張しているので、あなたは、チェックボックスが実際に代わりCheckedChangeListener

holder.chk_check_item 
      .setOnClickListener(new OnClickListener() { 

       @Override 
       public void onClick(View v) { 
        if(((CheckBox)v).isChecked()){ 
         //Checkbox is checked Perform logic here 
        } else { 

        } 


       } 
      }); 

のユーザーがタップしたときを検出するための標準的な OnClickListenerを使用することができます

チェックされた変更スクロール時にリスナーがチェックを正しく保持しないため、スクロール中にチェックボックスの状態が変更されるのはこのためです。試してみてください。それは=================
