您好我是Android Studio的新手,目前在我的activity_main xml中,我有一些带有一些文本视图的约束布局。
<android.support.constraint.ConstraintLayout
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/country_detail"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="edu.monash.fit2081.countryinfo.CountryDetails">
<TextView
android:id="@+id/textView"
android:layout_width="150dp"
android:layout_height="25dp"
//some code here
现在我想将它更改为片段并将该活动作为底部片段。我制作了这样的片段,但是如何将布局嵌套到我的帧布局中?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="edu.monash.fit2081.database_4.MainActivity">
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fragment_top"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/fragment_border"
/>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/country_detail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@id/fragment_top"
android:background="@drawable/fragment_border"
/>
</RelativeLayout>
任何帮助将不胜感激!

FrameLayout是一个ViewGroup,就像RelativeLayout:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/country_detail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@id/fragment_top"
android:background="@drawable/fragment_border"
>
<android.support.constraint.ConstraintLayout
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/country_detail"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="edu.monash.fit2081.countryinfo.CountryDetails">
<TextView
android:id="@+id/textView"
android:layout_width="150dp"
android:layout_height="25dp"
/>
</FrameLayout>
