I am building a layout for large screens, that is supposed to consist of 2 different parts, a left one and a right one. For doing that I thought using 2 Fragments is the right choice.
Then I had a look on the example of the navigation with the Master/Detail-Flow. It has a 2-pane layout, where on the right is the navigation, and on the left is the detail view.
But in that example, different from what I expected to see, for the detail view there is a FrameLayout
that then holds a Fragment
, instead of a Fragment
directly.
The layout XML looks like this (an example):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:baselineAligned="false"
android:divider="?android:attr/dividerHorizontal"
android:orientation="horizontal"
android:showDividers="middle"
tools:context=".WorkStationListActivity" >
<fragment
android:id="@+id/workstation_list"
android:name="de.tuhh.ipmt.ialp.history.WorkStationListFragment"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
tools:layout="@android:layout/list_content" />
<FrameLayout
android:id="@+id/workstation_detail_container"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="3" />
</LinearLayout>
My question now is: why is a FrameLayout
used instead of the Fragment
itself for the detail view? What is the reason or the advantage? Should I use it too?
