Now when I am calling Detail Fragement from Home Fragment my toolbar overlaps with status bar. If I call Detail fragment from any other fragment it is looking fine. Also toolbar in Home fragment does not overlap with status bar although xml for Home fragment and Detail fragment is nearly the same.

Picture one shows when detail fragment is opened normally

Picture two when detail fragment is opened from home page

Latest update: This solution is helping me https://medium.com/google-developers/windows-insets-fragment-transitions-9024b239a436 but there are lots of changes involved any other short way to do it?

Your activities should deal with the appbarlayout/coordinator layout. As for changing the toolbar from your fragment, you can simply do that by inflating a different menu.xml in `onCreateOptionsMenu()` and updating them in `prepareOptionsMenu()`. You have the same code in two different xmls which you can just put in your activity's xml. — denvercoder9, Mar 04 '18 at 16:21
I want to keep toolbar in fragment as every fragment in my app has different toolbar layout so keeping it in fragment — amodkanthe, Mar 04 '18 at 16:23
You should include how you are opening your fragments. I would recommend you to add a fragment container inside your main_content layout and then load your fragments into that container using replace. Both of them should look the same if you are loading them into the same container. — emirua, Mar 08 '18 at 00:44
make `fitWindowsSystem="false"` for everything but `AppBarLayout` and `Toolbar`. \n Also, — Rahul, Mar 11 '18 at 09:42
make `layout_height="match_parent"` for everything but `AppBarLayout` and `Toobar` where it is `"wrap_content"`. this should work. — Rahul, Mar 11 '18 at 09:44

The symptoms you mention are very similar to the ones, mentioned in this question. To recap from the answer that I have provided there, the issue is, that window insets are being dispatched the first time fragment is being shown, but they are not being next time you are making a fragment transaction.

You have to manually ask for the window insets to be dispatched in order to receive correct system bar paddings:


    private void replaceFragment() {
      getSupportFragmentManager().beginTransaction()
          .replace(R.id.content, new DetailFragment())
          // NOTE, we are performing `commitNow()` instead of ordinary `commit()`,
          // Because we want this commit to happen sychronously/immediately
          .commitNow();

      // Ask the framework to dispatch window insets once more to the root of your view hierarchy
      ViewCompat.requestApplyInsets(findViewById(R.id.root));
    }

I think you should add this in you detail fragment (just give it a try):

            app:contentInsetLeft="0dp"
            app:contentInsetStart="0dp"
            app:title="@string/empty"

            app:logo="@drawable/customimage"

and make one image as transparent add it as customimage for detail, this would be probably a trick. Thank you.
