我正在爲android製作應用程序。我需要向數據庫中插入一定的值。Android插入不起作用
這是從DatabaseHelper(使用SQLite)的方法:
public long insertMyAnime(MyList myList) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put("name", myList.getName());
values.put("description", myList.getDescription());
values.put("episodes", myList.getEpisodes());
values.put("genre", myList.getGenre());
values.put("rating", myList.getRating());
values.put("episodesWatched", myList.getEpisodesWatched());
values.put("stateId", myList.getStateId());
long id = db.insert("myList", null, values);
db.close();
return id;
}
而這正是我要插入的部分:
public void addAnime_onClick(View v){
anime = domParser.getAnime(name);
MyList myList = new MyList();
myList.setName(anime.getName());
myList.setDescription(anime.getDescription());
myList.setEpisodes(anime.getEpisodes());
myList.setGenre(anime.getGenre());
myList.setEpisodesWatched(0);
myList.setStateId(4);
myList.setRating(0);
db.insertMyAnime(myList);
}
而這正是該表如下所示:
//CREATE TABLE MYANIME
String CREATE_TABLE_MYLIST = "CREATE TABLE myList (" +
"id INTEGER PRIMARY KEY AUTOINCREMENT," +
"name TEXT," +
"description TEXT," +
"episodes INTEGER," +
"genre TEXT," +
"rating INTEGER," +
"episodesWatched INTEGER," +
"stateId INTEGER)";
db.execSQL(CREATE_TABLE_MYLIST);
從我按下按鈕插入時,應用程序崩潰。
你知道這個問題可能是什麼嗎?你會幫助我這麼多...
那麼「插入不起作用」對你來說意味着什麼? – laalto
正如我所說的,應用程序崩潰,「插入」並不難,所以我不認爲答案是遙遙領先的...... – Dominickus
如果發生崩潰,那就是堆棧跟蹤。展示下。 –
