Answer 1

拿到cursor对象后调用Cursor类的方法即可
如：

10

String[] strs = new String[cursor.getCount()];
String columnName="";
int position = 0;
// cursor.moveToPosition(position);
cursor.moveToFirst();
while (cursor.moveToNext()) {
int index = cursor.getColumnIndex(columnName);
String str = cursor.getString(index);
strs[position++] = str;
}
