This a terrible thing! It costs my a few hours! this is my table rows :

private String USER_ID = "user_id";
private String REMEMBER_UN = "remember_un";
private String REMEMBER_PWD = "remember_pwd";
private String HEAD_URL = "head_url";
private String USER_NAME = "user_name";
private String USER_PPU = "user_ppu";
private String CURRENT_TIME = "current_time";

Cursor c = db.rawQuery("SELECT * FROM " + TABLE +" ORDER BY " + CURRENT_TIME + " DESC",null);

Every time when I update the table , I will update the CURRENT_TIME for sort. But I found that it is not work.The result is not sorted what I want. Finally, I found that, the column "current_time" is the default row of sqlite.

The solution is, rename the column "cur_time" instead of "current_time".
