如何将RelativeLayout放在CoordinatorLayout中 [英] How to put RelativeLayout inside CoordinatorLayout

问题描述

我正在尝试重新创建搜索框，就像在Airbnb Android应用中一样。
所以我在工具栏和 RecyclerView 中使用 CoorinatorLayout 。

I'm trying to recreate the search box as it is in Airbnb Android app. So I'm using CoorinatorLayout with Toolbar and RecyclerView.

但是，当我在协调器中插入除这两件事以外的内容时，它不会显示。
这是我的代码：

But when I insert something inside the Coordinator besides those two things, it doesn't show up. Here is my code:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/slidingLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@color/red"
        app:layout_scrollFlags="scroll|enterAlways" />

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

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="50dp"
    android:layout_marginRight="50dp"
    android:layout_marginTop="20dp"
    android:background="@drawable/rounded_background"
    android:orientation="horizontal"
    android:padding="6dp"
    app:layout_scrollFlags="scroll|enterAlways">

    <EditText
        android:id="@+id/search"
        android:layout_width="0dp"
        android:layout_height="fill_parent"
        android:layout_weight="6"
        android:background="@null"
        android:fontFamily="sans-serif-light"
        android:hint="Unesite grad"
        android:paddingLeft="16dp"
        android:paddingStart="16dp" />

    <ImageView
        android:id="@+id/cancelSearch"
        android:layout_width="0dp"
        android:layout_height="40dp"
        android:layout_weight="1"
        android:padding="10dp"
        android:src="@drawable/ic_cancel" />
</LinearLayout>

<android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    android:layout_below="@id/appbar"
    android:background="#ffffff"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

，我将麻烦把搜索框放在RecyclerView上方。

But actually if this even worked, I would have the trouble of putting the search box above the RecyclerView.

我试图将所有内容都放在 RelativeLayout 内，但这没有实现。

I have tried to put everything inside the RelativeLayout but that didn't work.

这里也是我要制作

Here is also the picture of what I'm trying to make

编辑：

以下是带有RelativeLayout的代码

Here is the code with RelativeLayout

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/slidingLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

   <RelativeLayout

           android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
           android:background="#00000000">

           <android.support.v7.widget.Toolbar
               android:id="@+id/toolbar"
               android:layout_width="match_parent"
               android:layout_height="?attr/actionBarSize"
               android:background="@color/red"
               app:layout_scrollFlags="scroll|enterAlways"/>
   </android.support.design.widget.AppBarLayout>

   <RelativeLayout

          android:layout_marginRight="50dp"
          android:layout_marginTop="20dp"
          android:background="@drawable/rounded_background"
          android:orientation="horizontal"
          android:padding="6dp"
          app:layout_scrollFlags="scroll|enterAlways">

          <EditText

              android:hint="Unesite grad"
              android:paddingLeft="16dp"
              android:paddingStart="16dp" />

          <ImageView
              android:id="@+id/cancelSearch"
              android:layout_width="0dp"
              android:layout_height="40dp"
              android:layout_weight="1"
              android:padding="10dp"
              android:src="@drawable/ic_cancel" />
      </LinearLayout>
      <android.support.v7.widget.RecyclerView
           android:id="@+id/recyclerView"
           android:layout_width="match_parent"
           android:layout_height="fill_parent"
           android:layout_below="@id/appbar"
           android:background="#ffffff"
           app:layout_behavior="@string/appbar_scrolling_view_behavior" />
   </RelativeLayout>

推荐答案

我正在尝试做一些类似的操作，但屏幕底部带有广告横幅。我的解决方案是将 RelativeLayout 包裹在 CoordinatorLayout 之外，如下：

I was trying to do something a little similar, but with an ad banner at the bottom of the screen. My solution was to wrap the RelativeLayout outside the CoordinatorLayout as so:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/main_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

  <android.support.design.widget.CoordinatorLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_above="@+id/ad_view">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

      <android.support.v7.widget.Toolbar
          android:id="@+id/toolbar"
          android:layout_width="match_parent"
          android:layout_height="?attr/actionBarSize"
          android:background="?attr/colorPrimary"
          app:layout_scrollFlags="scroll|enterAlways"
          app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

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

    <android.support.v7.widget.RecyclerView
        android:id="@+id/my_list_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

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

  <com.google.android.gms.ads.AdView
      android:id="@+id/ad_view"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_centerHorizontal="true"
      android:layout_alignParentBottom="true"
      android:layout_gravity="center|bottom"
      app:adSize="SMART_BANNER"
      app:adUnitId="@string/admob_id" />

</RelativeLayout>

在 RecyclerView 一切似乎都正常。我可以想象，如果您遵循类似的原则，那么您应该会成为一个好人。

The toolbar properly hides when scrolling inside the RecyclerView and everything seems to be working just fine. I would imagine if you followed a similar principle you should be good-to-go.
