Answer 1

I integrated some code that I wrote with the code you provided. I think this should work, based upon you having used the generic Android ADT setup.

package twh.reviser.root;

import java.util.Locale;


import android.os.Bundle;
import android.renderscript.Int2;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.app.NavUtils;
import android.support.v4.view.ViewPager;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class MainActivity extends FragmentActivity {

    static final int NUM_ITEMS = 3;

    /**
     * The {@link android.support.v4.view.PagerAdapter} that will provide
     * fragments for each of the sections. We use a
     * {@link android.support.v4.app.FragmentPagerAdapter} derivative, which
     * will keep every loaded fragment in memory. If this becomes too memory
     * intensive, it may be best to switch to a
     * {@link android.support.v4.app.FragmentStatePagerAdapter}.
     */
    SectionsPagerAdapter mSectionsPagerAdapter;

    /**
     * The {@link ViewPager} that will host the section contents.
     */
    ViewPager mViewPager;

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


        // Create the adapter that will return a fragment for each of the three
        // primary sections of the app.
        mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());

        // Set up the ViewPager with the sections adapter.
        mViewPager = (ViewPager) findViewById(R.id.pager);
        mViewPager.setAdapter(mSectionsPagerAdapter);

    /** possibly missing from your code*/
        // For each of the sections in the app, add a tab to the action bar.
        for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {
            actionBar.addTab(actionBar.newTab()
                    .setText(mSectionsPagerAdapter.getPageTitle(i))
                    .setTabListener(this));
        }
    }

    @Override
    public void onTabSelected(ActionBar.Tab tab,
            FragmentTransaction fragmentTransaction) {
        // When the given tab is selected, switch to the corresponding page in
        // the ViewPager.
        mViewPager.setCurrentItem(tab.getPosition());
    }

    @Override
    public void onTabUnselected(ActionBar.Tab tab,
            FragmentTransaction fragmentTransaction) {
    }

    @Override

    @Override

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    /**

    public class SectionsPagerAdapter extends FragmentPagerAdapter {

        public SectionsPagerAdapter(Context c,FragmentManager fm) {
            super(fm);

        @Override

            if (position == 1) {

                fragment.setArguments(args);

            }
            return fragment;
        }

        @Override
        public int getCount() {
            // Show 3 total pages.
            return NUM_ITEMS;
        }

        @Override
        public CharSequence getPageTitle(int position) {
            Locale l = Locale.getDefault();
            switch (position) {
                case 0:
                    return getString(R.string.title_section1).toUpperCase(l);
                case 1:
                    return getString(R.string.title_section2).toUpperCase(l);
                case 2:
                    return getString(R.string.title_section3).toUpperCase(l);
            }
            return null;
        }
    }

    /**
     * A dummy fragment representing a section of the app, but that simply
     * displays dummy text.
     */
    public static class DummySectionFragment extends Fragment {
        /**

         * fragment.
         */
        public static final String ARG_SECTION_NUMBER = "section_number";

        public DummySectionFragment() {
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.fragment_main_dummy, container,    false);
            TextView dummyTextView = (TextView) rootView.findViewById(R.id.section_label);
                dummyTextView.setText(Integer.toString(getArguments().getInt(ARG_SECTION_NUMBER)));
            return rootView;
        }
    }

}

Create three xml files for each of the three fragments in res/layout/

Fragment_1.xml

Fragment_2.xml

Fragment_3.xml

Create three java files for the three fragments in src/twh.reviser.root

FragmentPage1.java

package twh.reviser.root;

public class FragmentPage1 extends Fragment  {

    Context c;

    public FragmentInputPage1(){
    }

    public FragmentInputPage1(Context c) {
        this.c = c;
    }

    @Override    
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View v = inflater.inflate(R.layout.Fragment_1, null);

        return v;

    }
}

FragmentPage2.java

package twh.reviser.root;

public class FragmentPage2 extends Fragment  {

    Context c;

    public FragmentInputPage2(){
    }

    public FragmentInputPage2(Context c) {
        this.c = c;
    }

    @Override    
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View v = inflater.inflate(R.layout.Fragment_2, null);

        return v;

    }
}

FragmentPage3.java

package twh.reviser.root;

public class FragmentPage3 extends Fragment  {

    Context c;

    public FragmentInputPage3(){
    }

    public FragmentInputPage3(Context c) {
        this.c = c;
    }

    @Override    
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View v = inflater.inflate(R.layout.Fragment_3, null);

        return v;

    }
}

If you want to get the value of an id from another fragment you can use the below, based upon FragmentPage1 having the following public variables declared

public static String a,b,c;

Within FragmentPage1.java

public class FragmentPage3 extends Fragment  {

Context c;

String a = "";
String b = "";
String c = "";

@Override    
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.Fragment_3, null);

    a = FragmentPage1.a;
    b = FragmentPage1.b;
    c = FragmentPage1.c;
