android - Sqlite query using where condition having more than one condition to satisfy -

-

please find wrong here

here _id , chek column of db write query search has id =id , check =number

 public cursor query(int id){     return mydatabase.query("question", null,"_id = "+id+ "and " +  "chek ="+number,null, null, null, null);    }

may you:

replace query these lines..

public cursor query(int id){ return mydatabase.query("question", null,"_id = "+id+ " , " +  "chek ="+number,null, null, null, null);

keep space between double quotes in , :" , " otherwise string
example: _id=3and check =9
