You should create a function inside activity to open new fragment and pass the activity reference to the fragment and on some event inside fragment call this function

Well my problem was that i used the code from the answer  which is checked as a solution here  but after the replacement was executed  the first layer was still visible and functionating under just opened fragment  My solution was simmple  i added    remove CourseListFragment this    the CourseListFragment is a class file for the fragment i tried to close   MainActivity java  but for specific section   navigation drawer fragment   if it makes more sense to you  so my code looks like this now    LecturesFragment nextFrag  new LecturesFragment                         getActivity   getSupportFragmentManager   beginTransaction                                remove CourseListFragment this                               replace   ViewGroup getView   getParent    getId    nextFrag   findThisFragment                                addToBackStack null                               commit      And it works like a charm for me

first of all  give set an ID for your Fragment layout  e g     lt androidx constraintlayout widget ConstraintLayout xmlns android  http   schemas android com apk res android  xmlns app  http   schemas android com apk res-auto  xmlns tools  http   schemas android com tools  android layout width  match parent  android layout height  match parent    android id    id cameraFragment    tools context   CameraFragment  gt    and use that ID to replace the view with another fragment java file  e g   ivGallary setOnClickListener new View OnClickListener            Override       public void onClick View v              UploadDoc uploadDoc  new UploadDoc               getActivity    getSupportFragmentManager   beginTransaction                      replace   R id cameraFragment    uploadDoc   findThisFragment                      addToBackStack null                     commit

Adding to  Narendra solution     IMPORTANT  When working with fragments  navigations is closely related to host acivity so  you can t justo jump from fragment to fragment without implement that fragment class in host Activity    Sample   public class MyHostActivity extends AppCompatActivity implements MyFragmentOne OnFragmentInteractionListener    Also  check your host activity has the next override function     Override public void onFragmentInteraction Uri uri      Hope this helps

Add following code in your click listener function   NextFragment nextFrag  new NextFragment    getActivity   getSupportFragmentManager   beginTransaction                 replace R id Layout container  nextFrag   findThisFragment                 addToBackStack null                commit      The string  findThisFragment  can be used to find the fragment later  if you need

This is more described code of  Narendra s code   First you need an instance of the 2nd fragment  Then you should have objects of FragmentManager and FragmentTransaction  The complete code is as below   Fragment2 fragment2 new Fragment2    FragmentManager fragmentManager getActivity   getFragmentManager    FragmentTransaction fragmentTransaction fragmentManager beginTransaction    fragmentTransaction replace R id content main fragment2  tag    fragmentTransaction addToBackStack null   fragmentTransaction commit      Hope this will work  In case you use androidx  you need getSupportFragmentManager   instead of getFragmentManager
