视图与工具栏重叠

问题描述：

我有一个带Activity的简单应用.当前Views与我的toolbar重叠:

I have a simple app with one Activity. Currently Views are overlapping with my toolbar:

我希望Views进入toolbar下，而不是进入其中.我该怎么办?

I want Views to go under the toolbar, not into it. How do I do this?

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <android.support.design.widget.CoordinatorLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary" />

    </android.support.design.widget.CoordinatorLayout>

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="asdasdasdasd"/>

</android.support.v4.widget.DrawerLayout>

styles.xml :(请注意windowDrawsSystemBarBackgrounds)

styles.xml: (note the windowDrawsSystemBarBackgrounds)

<resources>

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
    </style>
</resources>

答

不是使用DrawerLayout的正确方法.第一个视图应包含您要向用户显示的内容.以后您可以添加抽屉.对于您的示例，可以使用以下内容:

Not the right way of using DrawerLayout. The first view should contain the content you want to show the user. Later you can add drawers. For your example, you can use the following:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout    
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

  <android.support.design.widget.CoordinatorLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:fitsSystemWindows="true">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary" />

  </android.support.design.widget.CoordinatorLayout>

  <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="asdasdasdasd"/>
</LinearLayout>

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true" />

</android.support.v4.widget.DrawerLayout>
