This easy ! Try this !

package com.androidbegin.absviewpagertutorial;


import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.content.Intent;

import com.actionbarsherlock.app.SherlockFragment;



public class FragmentTab1 extends SherlockFragment {
    @Override

    private Button btn;
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // Get the view from fragmenttab1.xml
        View view = inflater.inflate(R.layout.fragmenttab1, container, false);
        btn = view.findViewById(R.id.algabra);

        btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent intent = new Intent(FragmentTab1.this, AlgabraHome.class);
            startActivity(intent);
        }


        return view;
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        setUserVisibleHint(true);
    }

}

Don't forget to add to your AndroidManifest.xml file the activity :

   <activity
        android:name="com.androidbegin.AlgabraHome">
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

I'm not sure if I forgot anything, I wrote this on the fly without testing it out cause I don't have the rest of your code.

Enjoy ! Let me know if it work
