Question

这适用于Android应用。第一个调用工作，而不是第二个调用，它们按顺序调用。没有错误。所有字符串都是应该的。第一个正确更新，但第二个不更新任何值。

///DOESN'T WORK
        mDbHelper.updateValue(SaveSlot, item, value1,value2,"S");



    public void updateValue(String saveslot, String item, String value1, String value2,String cat) {
        ContentValues args = new ContentValues();
        if (value1 !=null){

        args.put(VALUE1, value1);
        if (value2 !=null){
            args.put(VALUE2, value2);
        }}
        else if (value2 !=null){
        args.put(VALUE2, value2);
        }
        mDb.update(DATABASE_PUSHERS_TABLE, args, SAVE_SLOT + "=" + saveslot +" AND " + ITEM +" = "+item+" AND category = "+cat, null);
        return ;
    }

发现了一些错误消息......

Answer 1

在变量周围加一个引号修复它..

  mDb.update(DATABASE_PUSHERS_TABLE, args, SAVE_SLOT + " = '" + saveslot +"' AND " + ITEM +" = '"+item+"' AND category = '"+cat+"'", null);

SQLite更新语句。没有一直更新
