android development static fragment layout implementation

Realize thinking:

1. Need to write 2 or more sub-layouts

2. Write a Java class to implement the layout of the child and the parent class. (A sub-layout corresponds to a class)

3. Import the fragment layout in the parent class layout, and add the android:name="" attribute;

1. Write 2 layouts:

<?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="The layout below"
        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="The layout above"
        android:textSize="30sp"
        android:textColor="@color/colorBlack"
        android:maxEms="1"
        android:maxLines="5"/>
</LinearLayout>

2. Java class to achieve the sub-layout and parent-class layout

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. Import the fragment layout in the parent class layout, and add the android:name="" attribute;

<?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">
    <!--id must be added or an error will be reported -->
    <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>

running result:
