ผมมี class A ซึ่งเป็น Activity มีlayout ที่ไว้แสดง fragment (android.support.v4.widget.DrawerLayout)
ซึ่งผมสามารถนำ Fragment class มาแสดงในlayout นี้ได้ตามปกติ
แต่เมื่อผมมีการเรียกใช้อีก Activity นึง หรือ class B แล้วถ้าผมต้องการ นำ Fragment class ไปแสดงบนlayout ของ class A อย่างที่แล้วมา
มันจะทำไม่ได้ครับ
อยากทาบว่าเพราะอะไร
และวิธีแก้ปัญหาครับ
นี่คือ นี่คือ layout ของ class A ครับ

the container. A solid background is used for contrast
with the content view. -->
