如何膨胀背后另有一个视图 [英] How to inflate a view behind another

问题描述

原谅我，如果这是一个简单的问题，但是我是新来的Andr​​oid开发这个问题一直缠着我。

Forgive me if this is a simple question however I am new to Android Development and this problem has been bugging me.

我有包含的RelativeLayout和这个库com.devspark.sidenavigation.SideNavigationView一个基地布局文件。

I have a "base" layout file which contains a RelativeLayout and a com.devspark.sidenavigation.SideNavigationView from this library.

然后我有一个ViewPager其膨胀等布局（包括列表视图和progressBars）到这个活动。我的问题是，无论我尝试做的SideNavigationMenu总是出现膨胀的列表视图后面。我不知道发生了什么错，我在布局乱七八糟迷路。没有任何人有任何指针？

I then have an activity with a ViewPager which inflates other layouts (containing ListViews and progressBars) into this. My issue is that however I try and do it, the SideNavigationMenu always appears behind the inflated listviews. I'm not sure what's going wrong and I'm getting lost in a mess of Layouts. Does anyone have any pointers?

下面是我的基地布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".NewNews"
    tools:ignore="MergeRootFrame">  

<com.devspark.sidenavigation.SideNavigationView
    android:id="@+id/side_navigation_view_news"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clipChildren="false"/>

</RelativeLayout>

和它们充气的子-layouts之一的示例：

and an example of one of the "sub"-layouts which are inflated:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

<eu.erikw.PullToRefreshListView
    android:id="@+id/listView_all"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@android:color/transparent"/>

<ProgressBar
    android:id="@+id/progressBar_all"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center" />

</FrameLayout>

在此先感谢

推荐答案

相对布局不支持层。

视图是通过它们被添加到布局的顺序放置在彼此的顶部。

Views are placed on top of each other by the order they are added to the layout.

例如。

• 添加到viewA的RelativeLayout


• 添加到viewB的RelativeLayout


• viewB将盈方viewA的

膨胀背后的膨胀，另一个是充气前的另一种观点的一种方式。

One way to inflate "behind" is inflating the other view before the other one is inflated.

• 添加到viewB的RelativeLayout


• 添加到viewA的RelativeLayout


• viewA将盈方viewB的

或删除视图，并重新添加到RelativeLayout的

or remove the view and re-add it to the relativelayout

• 添加到viewA的RelativeLayout


• 添加到viewB的RelativeLayout


• 删除viewA


• 重新添加viewA


• viewA将盈方viewB的
