问题描述:

I'm working on an application in which tabs are implemented using FragmentActivity. Since, tabs are required throughout the application, fragments are used extensively to make the application compatible on all the versions of android.

As a consequence, I'm facing a problem in visualizing as to what fragments are present on the backstack. I'm sure there is a way to retrieve the list of fragments present on the backstack. Thanks.

网友答案:

The FragmentManager has methods:

getBackStackEntryCount()

getBackStackEntryAt (int index)

FragmentManager fm = getFragmentManager();

for(int entry = 0; entry < fm.getBackStackEntryCount(); entry++){
   Log.i(TAG, "Found fragment: " + fm.getBackStackEntryAt(entry).getId());
}
