Add Fragment as content to Activity in Android

Today we try add Fragment layout in another Activity layout, that reduce  complexity develop user interface. For this example we need 3 layout: main.xml, fragment1.xml, fragment2.xml, and 3 classes: MainActivity.java, Fragment1.java, Fragment2.java

Code of xml layouts

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"    >
</LinearLayout>
<?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"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:text="I m fragment ONE"
        android:gravity="center"
        android:background="#5eff6a"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>
<?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"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:text="I m fragment ONE"
        android:gravity="center"
        android:background="#5eff6a"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>

 

Code of Java — classes

package com.example.dynamicfragments;

import android.support.v7.app.ActionBarActivity;
import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.view.Display;
import android.view.Menu;
import android.view.MenuItem;
import android.view.WindowManager;

public class MainActivity extends ActionBarActivity {

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

		FragmentManager fm = getFragmentManager();
		FragmentTransaction fragmentTransaction = fm.beginTransaction();

		// get the display mode
		int displaymode = getResources().getConfiguration().orientation;
		if (displaymode == 1) { // it portrait mode
			Fragment1 f1 = new Fragment1();
			fragmentTransaction.replace(android.R.id.content, f1);
		} else {// its landscape
			Fragment2 f2 = new Fragment2();
			fragmentTransaction.replace(android.R.id.content, f2);
		}
		fragmentTransaction.commit();

	}
}

 

package com.example.dynamicfragments;

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

public class Fragment1 extends Fragment {
	public View onCreateView(LayoutInflater inflater, ViewGroup vg,
			Bundle savedInstanceState) {
		return inflater.inflate(R.layout.fragment1, vg, false);
	}
}

 

package com.example.dynamicfragments;

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

public class Fragment2 extends Fragment {
	public View onCreateView(LayoutInflater inflater, ViewGroup vg,
			Bundle savedInstanceState) {
		return inflater.inflate(R.layout.fragment2, vg, false);
	}
}
