我一直插科打诨与此几天了，希望这里有人能借给我一只手。

我有一个简单的两列布局中，左侧是带有按钮的导航栏，右​​边是一个内容面板。当用户点击该按钮（例如，第三个向下）之一，我想有一个浮动的观点一致，以这个按钮的权利，而是浮在内容窗格顶部。这里有一个图片来说明我的意思：

一切我已经试过塞到里面的导航栏或内容面板内的浮动菜单，这不是我想要的。有任何想法吗？这里基本上是我到目前为止有：

 ＆LT; RelativeLayout的
    的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
    机器人：layout_width =FILL_PARENT
    机器人：layout_height =FILL_PARENT
    机器人：方向=横向
＆GT;
    ＆LT;的LinearLayout
        机器人：layout_width =WRAP_CONTENT
        机器人：layout_height =FILL_PARENT
        机器人：方向=垂直
        机器人：layout_alignParentLeft =真
        机器人：ID =@ + ID / navigation_bar
    ＆GT;
        ＆LT;的FrameLayout
            机器人：layout_width =WRAP_CONTENT
            机器人：layout_height =WRAP_CONTENT
            机器人：layout_weight =0.14

            ＆LT;的ImageButton

解决方案

一个的FrameLayout可以让你有一个观点重叠的另一种观点。我不知道它是有道理让他们只有一个孩子看，因为你在你的例子。尝试具有的FrameLayout的最高水平，你的静态的观点作为第一个子元素，而浮动菜单的第二个孩子。

借助开发文档有一个很好的概述的布局类型，它可以帮助您开始。

I've been messing around with this for a few days now, hopefully someone here can lend me a hand.

I have a simple two-column layout, the left side is a navigation bar with buttons, the right side is a content panel. When the user taps one of the buttons (say, the third one down), I'd like to have a floating view aligned to the right of this button but floating on top of the content pane. Here's a picture to illustrate what I mean:

Everything I've tried shoves the floating menu inside the navigation bar or inside the content panel, which is not what I want. Any ideas? Here's basically what I have so far:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal"
>
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:orientation="vertical"
        android:layout_alignParentLeft="true"
        android:id="@+id/navigation_bar"
    >
        <FrameLayout 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="0.14"
        >
            <ImageButton 
                android:id="@+id/button1_btn"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/icon"
                android:layout_gravity="center"
            />
        </FrameLayout>
        <FrameLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="0.14"
        >
            <ImageButton 
                android:id="@+id/button2_btn"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/icon"
                android:layout_gravity="center"
            />
        </FrameLayout>
    </LinearLayout>
    <FrameLayout
        android:id="@+id/content"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="0.14"
        android:layout_toRightOf="@id/navigation_bar"
    >
    </FrameLayout>
</RelativeLayout>

A FrameLayout allows you to have a view overlapping another view. I'm not sure it makes sense to have them with only one child view, as you have in your example. Try having a FrameLayout at the highest level, with your "static" view as the first child element, and the floating menu as the second child.

The developer documents have a good overview the layout types, it might help you get started.
