Change current tab from a button click inside child fragment of the TabHost

Question

I have currently a working project with Navigation drawer and tabbed view using TabHost.I have 3 tabs in which each fragments are loaded as the child view of the tab.My requirement is that,when I click a button inside the child fragment,I need to navigate to another tab.Is this possible?Any help is appreciated.

Im using TabHost,and the 3 tabs are each a fragment of themselves.

Again,Im not using a TabActivity...
