Answer 1

在AND周围放置一些空格并在=后面添加这些"'":

String Reminder_Main="Reminder_Main",Car_ID="Car_ID",Reminder_Date="Reminder_Date"; 
 Cursor c = sdb.rawQuery("select Reminder_Id ,Reminder_Type,Reminder_Date,Reminder_Time,Reminder_Alert from " + Reminder_Main 
    +" where " + Car_ID + " = ? AND " + Reminder_Date + " = ? " , new String[] { summaryid,currentdate1}); 
c.moveToFirst(); 
c.moveToFirst(); 
int summarycount = c.getCount();
