地图底部的 RecyclerView Android
RecyclerView at the bottom of Map Android
我正在尝试实现类似于 Field Trip 应用程序的功能,如下图所示:
下面是我的片段布局xml:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.google.android.gms.maps.MapView
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<android.support.v7.widget.RecyclerView
android:id="@+id/map_recyclerView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
app:reverseLayout="true"
android:divider="@null"
android:layout_gravity="center_horizontal|bottom"/>
</FrameLayout>
但是我看不到 RecyclerView,而是 Map 占据了整个高度。
将 LinearLayout
放入 FrameLayout
并使用 weightSum;
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/main_rel"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:weightSum="2.0" >
<com.google.android.gms.maps.MapView
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<android.support.v7.widget.RecyclerView
android:id="@+id/map_recyclerView"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation="horizontal"
app:reverseLayout="true"
android:divider="@null"
android:layout_gravity="center_horizontal|bottom"/>
</LinearLayout>
使用具有百分比权重的 LinearLayout
(maps
为 60%,RecyclerView
为 40%)
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum = "1"
android:orientation="vertical">
<com.google.android.gms.maps.MapView
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.60"/>
<android.support.v7.widget.RecyclerView
android:id="@+id/map_recyclerView"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight = "0.40"
android:orientation="horizontal"
app:reverseLayout="true"
android:divider="@null"
android:layout_gravity="center_horizontal|bottom"/>
</LinearLayout>
<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.google.android.gms.maps.MapView
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.v7.widget.RecyclerView
android:id="@+id/map_recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="5dp"
android:layout_gravity="center_horizontal|bottom"
android:orientation="horizontal"
app:reverseLayout="true" />
</RelativeLayout>
问题在于使用了 FrameLayout。把FrameLayout改成LinearLayout就好了。所以它应该是:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.google.android.gms.maps.MapView
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<android.support.v7.widget.RecyclerView
android:id="@+id/map_recyclerView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
app:reverseLayout="true"
android:divider="@null"
android:layout_gravity="center_horizontal|bottom"/>
</LinearLayout>
尝试使用 LinearLayout
并将 android:layout_weight="1"
提供给您的 <com.google.android.gms.maps.MapView
并将 android:layout_weight="1"
提供给您的 <android.support.v7.widget.RecyclerView
如下布局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.google.android.gms.maps.MapView
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<android.support.v7.widget.RecyclerView
android:id="@+id/map_recyclerView"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight = "1"
android:orientation="horizontal"
app:reverseLayout="true"
android:divider="@null"
android:layout_gravity="center_horizontal|bottom"/
/>
</LinearLayout>
在 mainLayout 中采用垂直方向的线性布局
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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"
android:id="@+id/mainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="@+id/linearLayout"
android:weightSum="2">
<com.google.android.gms.maps.MapView
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<android.support.v7.widget.RecyclerView
android:id="@+id/map_recyclerView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|bottom"
android:divider="@null"
android:orientation="horizontal"
app:reverseLayout="true" />
</LinearLayout>
</FrameLayout>
