显示在AppBarLayout上方的FrameLayout [英] FrameLayout Shown Above AppBarLayout

问题描述

我有一个带有AppBarLayout和FrameLayout的简单CoordinatorLayout，但是无论FrameLayout上的layout_behavior属性如何，FrameLayout的内容都显示在AppBarLayout上.我尝试过将该属性添加到其他位置(例如在我的RecyclerView上)，但这是相同的行为.

I have a simple CoordinatorLayout with a AppBarLayout and FrameLayout, but the FrameLayout contents are being displayed over the AppBarLayout regardless of the layout_behavior attribute on the FrameLayout. I've tried adding that attribute elsewhere (like on my RecyclerView), but it's the same behavior.

下面是一张图片，显示了我的意思.

活动布局:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    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:fitsSystemWindows="true">

    <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"
            app:layout_scrollFlags="scroll|enterAlways"/>

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

    <FrameLayout
        android:id="@android:id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

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

片段布局:

<android.support.v7.widget.RecyclerView
android:id="@+id/checkins_recycler_view"
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:scrollbars="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

如何在活动"中添加片段:

How I add my fragment in my Activity:

final UserCheckinsFragment fragment = new UserCheckinsFragment();
    final Bundle arguments = new Bundle();
    UserCheckinsFragment.getArguments(arguments, items);
    fragment.setArguments(arguments);

    getSupportFragmentManager().beginTransaction().add(android.R.id.content, fragment,
            UserCheckinsFragment.class.getName()).commit();

推荐答案

xml中的FrameLayout ID(@android:id/content)和Fragment事务中的容器(android.R.id.content)引用系统 布局的根 ，然后将其放置在所有屏幕上.

The FrameLayout ID (@android:id/content) in the xml and the container (android.R.id.content) in the Fragment transaction refer to the system root of layout, then it is laid over the all screen.

要解决此问题，请使用不带android前缀的

To solve, use them without android prefix.
