Android Development (fragment) uses pop_back_stack_inclusive to jump to the bottom of the stack once. The use of similar ACTIVITY flag_activity_clear_top

Requirements Scenario:

The following scenario is encountered in development:

1. Create Fragment A display. The structure of this stack is:

　　

1

2. Create Fragment B and display. From bottom to top, the structure of the stack is:

2.Fragment B

1.Fragment A

3. Create Fragment C and display. From bottom to top, the structure of the stack is:

3.Fragment C

2.Fragment B

1.Fragment A

So, how do I jump from Fragment C to Fragment A at once?

implementation:

When you enter the stack, use the method

Passed in a parameter name, which is a fregment, and is used below.

Code:

Fragmentmanager Fragmentmanager == fragmentmanager.begintransaction ();   =  Fragment.getclass (). GetName (); Fragmenttransaction.replace (R.id.container, Fragment). Addtobackstack (Nameforbackstackstate). commit ();

To do this when it pops up:

Fragmentmanager.popbackstackimmediate (FragmentA.class.getName (), Fragmentmanager.pop_back_stack_ INCLUSIVE);

The second parameter of this method

Pop_back_stack_inclusive

Indicates that this pop-up behavior is a one-time out-of-stack "specified name" for all Fragment above Fragment.
