Answer 1

Try this way (the changes are marked) BTW instanciating a new object and naming it the same thing as the class itself is not good practice, may lead to major errors along the way

The main problem in your code was that and the fact that you were receiving a String called "customerid" but in your cursor you search for this "cus1"

public Customer getCustomer(String customerid){
    Customer customer = new Customer();  //<--
    Cursor cursor = database.query(DBHelper.CUSTOMER, allCustomer, DBHelper.CUSTOMER_ID +"=" + customerid, null, null, null, null); //<--
    cursor.moveToFirst();
    customer = cursorToCustomer(cursor); //<--
    cursor.close();
    return customer; //<--
}
