複数の連絡先の選択のリストビュー

Question

私はレイアウトインフレータを介してリストビューにチェックボックスを入れようとしましたが、成功しましたが、複数の連絡先を選択しても問題はありませんが、選択を解除すると&ダウン&当時その選択を解除チェックボックスのを自動的に選択し得るために行く...

Answer 2

この原因は、あなたがコードでOnClickListener()目覚めをnameCheckBox.setChecked()を呼び出し、そのコードを実行するときにということです。私はちょうどOnClickListener(null)を設定する前に同じ問題を解決して、チェックボックスをオンにしたかどうかを設定しました。

Answer 3

nameCheckBox.setOnClickListener（新しいOnClickListener（）{

  @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       isChecked[position_clicked] = position; 
       Log.d("position", String.valueOf(position)); 
      } 
     }); 

このコードに格納中のすべての位置より1つのARREリストを追加し、両方 高速ADD、第削除は 。前記リストに使用さを追加または削除位置にあなたの他の方法
