android:layout_height="match_parent"
android:layout_weight="1"
/>

- FrameLayout is acting as fragment container.
MainActivity class
- File: MainActivity.java
package com.example.fragmentexample;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
loadFragment(this, R.id.container1,new Fragment1(),"fragment1");
loadFragment(this, R.id.container2,new Fragment2(),"fragment2");
}
public static void loadFragment(Activity activity, int containerId, Fragment fragment, String tag)
{
activity.getSupportFragmentManager().beginTransaction().
replace(containerId, fragment,tag).commitAllowingStateLoss();
}
}
