How to implement show and hide fragment inside fragment in android

Question

How to implement show and hide fragment inside fragment in Android? I have added two fragment inside activity. One fragment containing menu and one fragment contain sub menu. I have lot of button in menu fragment like home, idea, etc. If i click idea button. I have to show sub menu. If I again click idea button, I have to hide the sub menu. Can anybody provide example, or how to access one view fragment in another fragment?

this is my layout main

?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<fragment class="com.gcm.fragment.CommonFragment"
            android:id="@+id/the_frag"
            android:layout_width="wrap_content"
            android:layout_height="match_parent" />  
 <fragment class="com.gcm.fragment.SubFragment"
            android:id="@+id/the_frag1"
            android:layout_marginTop="130dip"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />             


</LinearLayout>

In My fragment

package com.gcm.fragment;
import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.TextView;

public class CommonFragment extends Fragment implements OnClickListener {
    TextView txtIhaveIdea=null;
  boolean menuVisible=false;
    public View onCreateView(final LayoutInflater inflater, final ViewGroup container, final Bundle savedInstanceState) { 
        ViewGroup layout = (ViewGroup) inflater.inflate(R.layout.collapsed_menu2, container, false); 

        txtIhaveIdea=(TextView)layout.findViewById(R.id.txtIhaveAnIdea);
        txtIhaveIdea.setOnClickListener(this);

        return layout; 
        }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        if(!menuVisible)
        {
        FragmentManager fm = getFragmentManager(); 
        FragmentTransaction ft = fm.beginTransaction(); 
        fm.beginTransaction(); 
        Fragment fragOne = new SubFragment(); 
        ft.show(fragOne);
        }
        else
        {
            FragmentManager fm = getFragmentManager(); 
            FragmentTransaction ft = fm.beginTransaction(); 

            fm.beginTransaction(); 
            Fragment fragOne = new SubFragment(); 
            ft.hide(fragOne);   
        }

    } 



}

You could try get framelayout or fragment by id and change its visibility

View frag = findViewById(R.id.my_fragment);
frag.setVisibility(View.VISIBLE);
