我创建了一个工具栏，我设置为我的动作条和我有它透明的，我的问题是我要它覆盖了内容的其余部分，现在它的行为像一个正常的动作条在我的的LinearLayout 停止下方。如何让我的工具栏覆盖我的布局，并有布局充满整个屏幕？

I created a ToolBar which I set as my ActionBar and I have it transparent, my question is I want it to overlay the rest of the content, right now it is acting like a normal ActionBar where my LinearLayout "stops" below it. How do I make my ToolBar overlay my layout and have that layout fill the whole screen?

的样式原动作条就是：

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowActionBarOverlay">true</item>
</style>

我的工具栏：

<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
app:theme="@style/ThemeOverlay.AppCompat.ActionBar"
android:layout_width="match_parent"
android:layout_height="200dp"
android:minHeight="?attr/actionBarSize"
android:background="@android:color/transparent"/>

和我的工具栏声明：

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setBackgroundResource(Color.TRANSPARENT);
setSupportActionBar(toolbar);

我觉得我失去了一些东西很简单，但搜索我找不到我正在寻找解决方案之后。任何帮助将是AP preciated！

I feel like I'm missing something really simple but after searching I couldn't find the solution I'm looking for. Any help would be appreciated!

编辑： 这是我的完整的XML主要布局：

Here is my full XML Main Layout:

<FrameLayout 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"
tools:context=".MainActivity">

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    app:theme="@style/ThemeOverlay.AppCompat.ActionBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="@android:color/transparent"/>

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Main layout -->
    <FrameLayout
        android:id="@+id/main_fragment_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- Nav drawer -->
    <fragment
        android:id="@+id/fragment_drawer"
        android:name="rsay.android.scrollbanner.NavigationDrawerFragment"
        android:layout_width="@dimen/navigation_drawer_width"
        android:layout_height="match_parent"
        android:layout_gravity="left|start" />
</android.support.v4.widget.DrawerLayout>

推荐答案

你是在正确的轨道上。最简单的方式，你可以做到这一点是使用的FrameLayout 其中内容的ViewGroup 将 match_parent ，而工具栏是在此之上的ViewGroup

You are on right track. Simplest way you can do it is using FrameLayout where the content ViewGroup will match_parent while the Toolbar is on top of this ViewGroup

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">


    <!-- This can be any child. For sample purposes I assume this layout contains fragments -->
    <LinearLayout  
        android:background="?attr/colorPrimary"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/fragment_container"
        android:orientation="horizontal"/>


    <android.support.v7.widget.Toolbar
       xmlns:app="http://schemas.android.com/apk/res-auto"
       android:id="@+id/toolbar"
       app:theme="@style/ThemeOverlay.AppCompat.ActionBar"
       android:layout_width="match_parent"
       android:layout_height="200dp"
       android:minHeight="?attr/actionBarSize"
       android:background="@android:color/transparent">
        </android.support.v7.widget.Toolbar>

</FrameLayout>
