Android-防止导航抽屉覆盖标题栏

Question

I recently opened a project in Android Studio and selected a Navigation Drawer Activity. It created the navigation drawer, except that it's being displayed in a way that I don't like - the navigation drawer is displayed on top of the title bar, for example:

Instead, I'd like it to be like:

In this "correct" example, the title bar - "Home" is being displayed, alongside a closing arrow, while the navigation drawer opens.

EDIT

After Tomer Shemesh's suggestion, the <android.support.v7.widget.Toolbar was changed to:

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay"
        android:layout_marginTop="?attr/actionBarSize"/>

And then, the result is:

So there is no solution just yet.

Adding to Tomer suggestion, android:layout_marginTop="?attr/actionBarSize" should be applied to android.support.design.widget.NavigationView . I dont see Navigation View in app_bar_main.xml .

Adding this will give you action bar with a opaque overlay. It will look like this Image with opaque overlay

You can remove opaque overlay by setting scrimColor to transparent of DrawerLayout in your Navigation Drawer Activity .

mDrawerLayout = (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_refonte_base, null); mDrawerLayout.setScrimColor(ContextCompat.getColor(this,android.R.color.transparent));

Now it will look like this. Image with scrim color as transparent
