Toolbar overlapping below status bar

Use android:fitsSystemWindows="true" in the root view of your layout (LinearLayout in your case). And android:fitsSystemWindows is an

internal attribute to adjust view layout based on system windows such as the status bar. If true, adjusts the padding of this view to leave space for the system windows. Will only take effect if this view is in a non-embedded activity.

Must be a boolean value, either "true" or "false".

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

This corresponds to the global attribute resource symbol fitsSystemWindows.

For me, the problem was that I copied something from an example and used

<item name="android:windowTranslucentStatus">true</item>

just removing this fixed my problem.

None of the answers worked for me, but this is what finally worked after I set:

android:fitsSystemWindows="false"

In parent activity layout file it's not suggested at many places but it's work for me and saves my day

Just set this to v21/styles.xml file

 <item name="android:windowDrawsSystemBarBackgrounds">true</item>
 <item name="android:statusBarColor">@color/colorPrimaryDark</item>

and be sure

 <item name="android:windowTranslucentStatus">false</item>
