Android: fragments overlapping issue

Question

I am facing a problem of overlapping fragments when i switch between tabs and attach fragments to a tab view below is my code please help

public class Fragme         


        

Answer 1

It all has to do with the engineering behind the replace and the addToBackStack methods.

The replace method will actually do two things. Hide the existing fragment (let's say A) and add a new one (let's say B) in the container.

Adding that transaction to the back stack will do the opposite. Remove B and add A.

So, the solution to your problem is
1. use addToBackStack method.
2. make sure that the reverse replacement of fragments is the correct order

The second suggestion is really important, because it is pretty often that at some point the current fragment is not removed and another one is added, which causes the two fragments showing at the same time.
