我尝试将我的ActionBar迁移到AppCompat 21方式（使用设置为ActionBar的工具栏小部件），但它没有被显示或被MapFragment隐藏。
这是我的活动：

FrameLayout内的元素排序（以及API 21+中的高程和z平移）定义了z排序。您将Toolbar元素放置在内容片段之前，该片段设置为在两个维度中与父级匹配，因此内容片段完全覆盖Toolbar。
请尝试以下操作，这只是颠倒了顺序：
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.br.myapp.MapActivity" />
<android.support.v7.widget.Toolbar
xmlns:sothree="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/main_toolbar"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
sothree:theme="@style/MyApp.Widget.ActionBar.Solid"
android:layout_width="match_parent"/>
</FrameLayout>

只需检查您的小部件是否在适当的位置。
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="@dimen/appbar_padding_top"
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:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom" />
</FrameLayout>

就像常规片段事务一样，准备一个容器，以便稍后使用代码将片段添加到其中：
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:id="@+id/app_bar"
style="@style/AppBarLayoutStyle"
android:background="@color/red"
android:minHeight="?attr/actionBarSize"
app:elevation="0dp">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
style="@style/BlackTitleBarStyle"
android:background="@android:color/transparent"
app:titleTextColor="@color/white"/>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="@+id/map_fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
然后在其中添加SupportMapFragment。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = new SupportMapFragment();
mapFragment.getMapAsync(this);
getSupportFragmentManager().beginTransaction()
.add(R.id.map_fragment_container, mapFragment)
.commit();
}
