代码：

SQLiteDatabase database = SQLiteDatabase.openOrCreateDatabase(appFilesDir.getAbsolutePath() + ConstantsUtil.HEAL_YOUR_BODY_DBFILE_PATH, null);
// query all data
String sql = "select id,problem from bookdata";
Cursor cursor = database.rawQuery(sql,null);
if (cursor.getCount() > 0)
{
cursor.moveToFirst();
ProblemData pd = null;
while(!cursor.isLast()){
int id = cursor.getInt(cursor.getColumnIndex("id"));
String problemName = cursor.getString(cursor.getColumnIndex("problem"));
pd = new ProblemData(id,problemName);
problemDataSet.add(pd);
cursor.moveToNext();
}

int id = cursor.getInt(cursor.getColumnIndex("id"));
String problemName = cursor.getString(cursor.getColumnIndex("problem"));
pd = new ProblemData(id,problemName);
problemDataSet.add(pd);
}

原因：字段写错了，

solution: ID Problem
