Android Tablet PC development---fragment

Fragmentation is a UI fragment that can be embedded in an activity, which makes the program more reasonable and fully use the space of a large screen, and fragmentation is usually used in tablet development.

Simple example

Left fragment layout

<?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" >

    <button
        Android:id= "@+id/button1"
        Android:layout_width= "Wrap_content"
        android:layout_height= "Wrap_content"
        android:text= "button"
        android:layout_gravity= "Center"/>

</LinearLayout>

Package com.example.fragmenttest;

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 Administrator on 2016/3/2.
*/
public class Leftfragment extends Fragment {

    @Nullable
    @Override
    Public View Oncreateview (layoutinflater inflater, ViewGroup container, Bundle savedinstancestate) {

        View view = Inflater.inflate (R.layout.left_fragment,container,false);
        return view;
    }
}

Right Fragment layout

<?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= "#00ff00" >

    <textview
        Android:id= "@+id/text_view"
        Android:layout_width= "Wrap_content"
        android:layout_height= "Wrap_content"
        Android:text= "This is a text"
        Android:textsize= "20SP"
        android:layout_gravity= "Center"/>



</LinearLayout>

Package com.example.fragmenttest;

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 Administrator on 2016/3/2.
*/
public class Rightfragment extends Fragment {

    @Nullable
    @Override
    Public View Oncreateview (layoutinflater inflater, ViewGroup container, Bundle savedinstancestate) {
        View view = Inflater.inflate (R.layout.right_fragment,container);
        return view;
    }
}

Main interface

<?xml version= "1.0" encoding= "Utf-8"?>
<linearlayout xmlns:android= "Http://schemas.android.com/apk/res/android"
    Android:layout_width= "Match_parent"
    android:layout_height= "Match_parent" >

    <fragment
        Android:id= "@+id/left_fragment"
        Android:name= "Com.example.fragmenttest.LeftFragment"
        Android:layout_width= "0DP"
        android:layout_height= "Match_parent"
        android:layout_weight= "1"/>

    <fragment
        Android:id= "@+id/right_fragment"
        Android:name= "Com.example.fragmenttest.RightFragment"
        Android:layout_width= "0DP"
        android:layout_height= "Match_parent"
        android:layout_weight= "1"/>

</LinearLayout>

Package com.example.fragmenttest;

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);
    }
}
