Fragment静态实现

读了上一篇文章《Fragment基础详解》，相信大家对Fragment有了一定的了解，接下来让我们来看看Fragment的静态实现。

MainActivity.java

package hongbao.com.hongbao;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

activity_main.xml

<?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:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="hongbao.com.hongbao.MainActivity">

    <fragment
        android:id="@+id/my_fragment1"
        android:name="hongbao.com.hongbao.MyFragment1"
        android:layout_width="match_parent"
        android:layout_height="100dp" />
    <fragment
        android:id="@+id/my_fragment2"
        android:name="hongbao.com.hongbao.MyFragment2"
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:layout_below="@+id/my_fragment1"/>
    <fragment
        android:id="@+id/my_fragment3"
        android:name="hongbao.com.hongbao.MyFragment3"
        android:layout_width="match_parent"
        android:layout_height="300dp"
        android:layout_below="@+id/my_fragment2"/>
</RelativeLayout>

MyFragment1.java

package hongbao.com.hongbao;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class MyFragment1 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.myfragment1_layout, container, false);
    }
}

myfragment1_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorPrimaryDark">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="This is Fragment1"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />
</RelativeLayout>

MyFragment2.java

package hongbao.com.hongbao;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class MyFragment2 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.myfragment2_layout, container, false);
    }
}

myfragment2_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorAccent">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="This is Fragment2"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />
</RelativeLayout>

MyFragment3.java

package hongbao.com.hongbao;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class MyFragment3 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.myfragment3_layout, container, false);
    }
}

myfragment3_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorPrimary">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="This is Fragment3"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />
</RelativeLayout>

运行结果：
