SQL 获取某张表最后一行的ID

public long getLastId(){
    
    
    String query = "SELECT ROWID from "+TABLE_NAME+" order by ROWID DESC limit 1";
    Cursor c = db.rawQuery(query,null);
    long lastId=0;
    if (c != null && c.moveToFirst()) {
    
    
        lastId = c.getLong(0); //The 0 is the column index, we only have 1 column, so the index is 0
    }
    return lastId;
}
