DrawerLayout中视图的大小和单击行为错误 [英] Wrong size and click behavior for Views in DrawerLayout

问题描述

我有一个Activity的布局，正在尝试向其添加导航抽屉.

I have a layout for an Activity that I'm trying to add a navigation drawer to.

问题是，要正常工作，我需要使用:

The problem is, to work properly, I need to use:

<android.support.v4.widget.DrawerLayout

代替:

<RelativeLayout 

但是它把事情搞砸了.我的ProgressBar变得更大了，我的RecyclerView无法工作，当我单击某些内容时，应用程序将我注销了，等等.

but it messes things up. My ProgressBar becomes much bigger, my RecyclerView doesn't work, the app logs me out when I click something, etc.

我的布局XML:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.st.mf.UserAreaActivity"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:padding="@dimen/activity_vertical_margin"
    android:background="#fff">

    <ProgressBar
        android:id="@+id/progressBar1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true" />

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentTop="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentLeft="true"
        android:layout_marginTop="20dp" />

    <android.support.design.widget.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        app:menu="@layout/navigation_menu"
        android:layout_gravity="start">
    </android.support.design.widget.NavigationView>

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

如何创建我的抽屉菜单而不弄乱其他所有内容?

How can I create my drawer menu without messing everything else up?

推荐答案

不是抽屉的DrawerLayout的任何直接子级View都被视为内容View，并将其放置在match_parent中两个方向，无论您在其上设置了width和height属性.在您的情况下-实际上，在大多数情况下-您只需要一个内容View，因此其余非抽屉View都应全部放在一个ViewGroup中.

Any direct child View of a DrawerLayout that's not a drawer is considered a content View, and will be laid out to match_parent in both directions, regardless of the width and height attributes you've set on it. In your case - indeed, in most cases - you only need one content View, so the rest of the non-drawer Views should all be inside a single ViewGroup.

我们会将您的ProgressBar和RecyclerView都放置在用作内容View的RelativeLayout内，它们将保留您设置的布局属性.例如:

We'll place your ProgressBar and RecyclerView both inside a RelativeLayout that acts as the content View, where they'll keep the layout attributes you've set. For example:

<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"
    tools:context="com.st.mf.UserAreaActivity"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="@dimen/activity_vertical_margin"
    android:background="#fff">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <ProgressBar
            android:id="@+id/progressBar1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true" />

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_alignParentTop="true"
            android:layout_alignParentStart="true"
            android:layout_alignParentLeft="true"
            android:layout_marginTop="20dp" />

    </RelativeLayout>

    <android.support.design.widget.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        app:menu="@layout/navigation_menu"
        android:layout_gravity="start">
    </android.support.design.widget.NavigationView>

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

请注意，内容View应该始终在任何抽屉之前列出，以保持正确的z顺序；即，将抽屉放在内容的顶部.

Note that the content View should always be listed before any drawers, to maintain proper z-ordering; i.e., to keep the drawers on top of the content.
