اريد شرح في كيفيه اظهار معلومات من قاعده البيانات في الاندرويد

السلام عليكم 

اريد شرح مفصل  كيفيه اظهار معلومات من قاعده البيانات في الاندرويد 

فكره برنامجي هي عمل search  لمواقع سجلتها في قاعده البيانات ولكن اريد ان افهم كيف اطبق الفكره واحظر المعلومات عندما يبحث المستخدم عن موقع معين واظهارها في الاندرويد

اريد الطريقه ضروري لو سمحتو

وايضا عندي مشكله في عرض البيانات لمستخدم معين 

الفكره هي عندما يتم تسجيل دخول المستخدم تظهر له جميع بياناته المسجله مسبقا في قاعده البيانات ولكن عندي مشكله ولا تظهر عندي البيانات
