我使用android studios导航抽屉活动创建了导航抽屉.

I created the navigation drawer using android studios navigation drawer activity..

推荐答案

肯定地android:layout_marginTop="?attr/actionBarSize"在

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/my_drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="?attr/actionBarSize">

但是问题是抽屉布局位于工具栏的顶部.这就是为什么褪色在这里. 您可以通过以下方式消除褪色

But the problem is drawerlayout is top of the toolbar. That is why the fading here. you can remove fading by

mDrawerLayout.setScrimColor(getResources().getColor(android.R.color.transparent));

但是在某些设备上，它可能看起来像是有线的.

But on some devices it may look wired.

使用Android Studio时.我们可以创建NavigationDrawerActiviity 有3个文件名为

When working with Android studio. We can create NavigationDrawerActiviity There are 3 files named

activity_main.xml

activity_main.xml

app_bar_main.xml

app_bar_main.xml

nav_header_main.xml

nav_header_main.xml

content_main.xml

content_main.xml

因此我们可以跳过app_bar_main.xml并删除褪色.

So we can skip app_bar_main.xml and we can remove the fading.

将活动主体的根视图设为垂直" LinearLayout

Make the root view of the activity main as Vertical LinearLayout

<LinearLayout 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:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:fitsSystemWindows="true"
tools:context="com.example.MainActivity">
</LinearLayout>

在activity_main.xml中添加DrawerLayout，并在DrawerLayout中包含content_main.xml.并在DrawerLayout上方添加AppBarLayout.

In activity_main.xml add DrawerLayout and include content_main.xml in DrawerLayout. and Add AppBarLayout above the DrawerLayout.

<LinearLayout 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:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.qproinnovations.schoolmanagement.activity.HomeActivity">
    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        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:popupTheme="@style/AppTheme.PopupOverlay" >

        </android.support.v7.widget.Toolbar>

    </android.support.design.widget.AppBarLayout>
    <android.support.v4.widget.DrawerLayout
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        tools:openDrawer="start">
    <!-- drawer view -->
        <include layout="@layout/content_main" />
<!-- drawer content -->
        <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"
            app:menu="@menu/activity_home_drawer" />
    </android.support.v4.widget.DrawerLayout>

</LinearLayout>

setContentView(R.layout.activity_main);
