Question

我在一个数据库中有多个表（令牌和推文）。令牌表工作正常，我可以正确插入和更新内容，但我的tweets表抛出一个错误（SQLiteException接近“CREATE”）虽然它看起来我已正确输入所有内容。我尝试从手机中删除应用程序并重新开始，但它只是拒绝插入我的for循环中。

这是我的doInBackground方法，它从用户的时间轴获取推文并尝试将其存储在tweets表中：列表responseList = twitter.getHomeTimeline（页面）;

            for (twitter4j.Status status : responseList)
            {               
                int rt_amount = status.getRetweetCount(); 
                String rt = Integer.toString(rt_amount);

                String username          = status.getUser().getScreenName(); 
                String profile_image_url = status.getUser().getProfileImageURL(); 
                String message           = status.getText(); 

                int  favoriteCount       = status.getFavoriteCount(); 
                String favCount          = Integer.toString(favoriteCount);

                String name = status.getUser().getName(); 

                String createdTime = status.getCreatedAt().toGMTString();       

                storeTweet.storeTweet(message, username, name, rt, createdTime, profile_image_url, favCount, "hi"); 
            }

String CREATE_TWEETS_TABLE = "CREATE TABLE " + TABLE_TWEETS + 
"("
        + T_COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + T_MESSAGE + " TEXT," 
        + T_RETWEET_COUNT + " TEXT," + T_FAVORITE_COUNT + " TEXT," + T_USER + " TEXT," 
        + T_REAL_SCREENNAME + " TEXT," + T_MEDIA_URIS + " TEXT," + T_PROFILE_URL + " TEXT," + T_CREATED_TIME + " TEXT)";

的onCreate：

@Override
public void onCreate(SQLiteDatabase database)
{ 
    database.execSQL(CREATE_TOKENS_TABLE);
    database.execSQL(CREATE_TWEETS_TABLE);
}

addTweet：

public void addTweet(Tweet tweet)
{ 
    SQLiteDatabase db = this.getWritableDatabase(); 
    ContentValues values = new ContentValues();

    values.put(T_MESSAGE, tweet.getMessage());
    values.put(T_FAVORITE_COUNT, tweet.getFavoriteCount());
    values.put(T_RETWEET_COUNT, tweet.getRtCount());
    values.put(T_USER, tweet.getUsername());
    values.put(T_REAL_SCREENNAME, tweet.getRealName());
    values.put(T_MEDIA_URIS, tweet.getMediaUris());
    values.put(T_PROFILE_URL, tweet.getProfileImageUrl());
    values.put(T_CREATED_TIME, tweet.getCreatedTime());

    db.insertOrThrow(CREATE_TWEETS_TABLE, null, values);

    db.close();
}

StoreTweet.java：

public class StoreTweet 
{
    private DBHelper db; 
    private Context context;  

    public StoreTweet(Context context){ 
        this.context = context; 
    }

    public void storeTweet(String message, String username, String realName, String rtCount, String createdTime, 
            String profileImageUrl, String favoriteCount, String mediaUris)
    { 
        db = new DBHelper(context);
        db.addTweet(new Tweet(message, username, realName, rtCount, createdTime, profileImageUrl, favoriteCount, mediaUris));
    }
}

Answer 1

您没有通过CREATE TABLE执行insertOrThrow()语句 - 即在您的SQL语句中添加INSERT INTO。请改用execSQL()。

Answer 2

insertOrThrow的第一个参数必须是表名（TABLE_TWEETS），而不是创建整个表的语句（CREATE_TWEETS_TABLE）。

SQLiteException near＆＃34; CREATE＆＃34;
