Removing toolbar heights for a specific fragment

Question

How to set Elevation to 0 or disable it for a specific fragment of my NavigationDrawer ? Perhaps programmatically or with a theme?

toolbar.setElevation(0) doesn't seem to work.

This "my onNavigationItemSelected does not work, the height will not change:

 if (item.getItemId() == R.id.drawer_menu_account) { if (getSupportActionBar() != null) { getSupportActionBar().setElevation(0); } } else { if (getSupportActionBar() != null) { getSupportActionBar().setElevation(8); } } 

And my coordinator layout with a toolbar

 <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout 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:fitsSystemWindows="true" tools:context=".activity.MainActivity"> <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/AppTheme.AppBarOverlay"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" app:popupTheme="@style/AppTheme.PopupOverlay" /> </android.support.design.widget.AppBarLayout> <FrameLayout android:id="@+id/content_frame" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_marginTop="?attr/actionBarSize" /> <android.support.design.widget.FloatingActionButton android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="bottom|end" android:layout_margin="@dimen/fab_margin" android:src="@drawable/ic_add_24dp" /> </android.support.design.widget.CoordinatorLayout> 

SOLVED - thanks to Amir! Work with it in my onNavigationItemSelected

 if (android.os.Build.VERSION.SDK_INT >= 21) { if (item.getItemId() == R.id.drawer_menu_account) { appBar.setElevation(0); } else { appBar.setElevation(8); } } 

Answer 1

To remove the shadow on the toolbar, use

app:elevation="0" in AppBarLayout xml or

use mAppBarLayout.setTargetElevation(0) in java.

It worked for me.

Answer 2

Put this code in the Fragment in which you want to hide the ToolBar .

 @Override public void onResume() { super.onResume(); ((AppCompatActivity)getActivity()).getSupportActionBar().setElevation(0); }
