私はTextViewに何をしましたか？

Question

OKだから私はさまざまなソースから一緒に手錠をかけたカーソルアダプタを持っていて、主に自分の名前フィールドを除いて動作するようです。各名前のリストビューに2つのチェックボックスがありますが、私の名前はすべて同じ名前（同じ名前）になります

誰かが私が作成した問題を見つけますか？あなたの助けに感謝します。

public class MyDataAdapter extends SimpleCursorAdapter { 
private Cursor c; 
private Context context; 
private ArrayList<String> list = new ArrayList<String>(); 
private ArrayList<Boolean> itemCheckedHere = new ArrayList<Boolean>(); 
private ArrayList<Boolean> itemCheckedLate = new ArrayList<Boolean>(); 
private ArrayList<Integer> itemCheckedIdx = new ArrayList<Integer>(); 
int idxCol; 
int idx; 

// itemChecked will store the position of the checked items. 

public MyDataAdapter(Context context, int layout, Cursor c, String[] from, 
     int[] to) { 
    super(context, layout, c, from, to); 
    this.c = c; 
    this.context = context; 
    c.moveToFirst(); 
    for (int i = 0; i < c.getCount(); i++) { 
     itemCheckedHere.add(i, false); // initializes all items value with false 
     itemCheckedLate.add(i, false); // initializes all items value with false 
    }

Answer 1

あなたは自分を蹴るつもりです。あなたは、リストビュー内のインデックスに対応する位置にカーソルを移動するのを忘れ：

c.moveToPosition(pos) 

Answer 2

アダプタでカーソルを正しい行に設定されていません。

まず、カーソルとコンテキストのメンバー変数を取り除く必要があります。

public class MyDataAdapter extends SimpleCursorAdapter { 
private ArrayList<String> list = new ArrayList<String>(); 
private ArrayList<Boolean> itemCheckedHere = new ArrayList<Boolean>(); 
private ArrayList<Boolean> itemCheckedLate = new ArrayList<Boolean>(); 
private ArrayList<Integer> itemCheckedIdx = new ArrayList<Integer>(); 


// itemChecked will store the position of the checked items. 

public MyDataAdapter(Context context, int layout, Cursor c, String[] from, int[] to) { 
    super(context, layout, c, from, to); 

    for (int i = 0; i < c.getCount(); i++) { 
     itemCheckedHere.add(i, false); // initializes all items value with false 
     itemCheckedLate.add(i, false); // initializes all items value with false 
    } 
} 

public void bindView (View inView, Context context, Cursor cursor){ 
    super.bindView(inView,context,cursor); 

    TextView studentName; 
    ImageView studentPhoto; 

    //inView is never null in bindView 

    final CheckBox cBoxH = (CheckBox) inView.findViewById(R.id.attend); 
    final CheckBox cBoxL = (CheckBox) inView.findViewById(R.id.late); 

    // set up name field 

    studentName = (TextView) inView.findViewById(R.id.stuname); 
    if (studentName != null) 
    { 
      int index = cursor.getColumnIndex(gradeBookDbAdapter.KEY_NAME); 
      String name = cursor.getString(index); 
      studentName.setText(name); 
    } 

    //your other code 
} 

//other methods 

}
