Question

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：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

Answer 1

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>

Answer 2

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();
}

工具栏未显示或MapFragment未显示
