实现思维：

1.需要写2个或者多个子布局

2.写一个Java的class去实现将子布局与父类布局铺满。（一个子布局对应一个class）

3.在父类布局中导入fragment布局，并且添加android：name=“”属性；

1.写2个布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorAccent">
<TextView
android:layout_marginTop="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="下面的布局"
android:textSize="30sp"
android:textColor="@color/colorBlack"
android:maxEms="1"
android:maxLines="5"
android:layout_gravity="center"
/></LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_marginTop="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="上面的布局"
android:textSize="30sp"
android:textColor="@color/colorBlack"
android:maxEms="1"
android:maxLines="5"/>
</LinearLayout>

2.Java的class去实现将子布局与父类布局铺满

package com.example.lenovo.mydebrisdemo;import android.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;/**
* Created by lenovo on 2018/5/5.
*/public class Top extends Fragment {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.top_fragment,container,false);
return view;
}
}

package com.example.lenovo.mydebrisdemo;import android.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;/**
* Created by lenovo on 2018/5/5.
*/public class Button extends Fragment {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.botton_fragment,container,false);
return view;
}
}

3.父类布局中导入fragment布局，并且添加android：name=“”属性；

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">

<fragment
android:id="@+id/top"
android:name="com.example.lenovo.mydebrisdemo.Top"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<fragment
android:id="@+id/button"
android:name="com.example.lenovo.mydebrisdemo.Button"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/></LinearLayout>
