サポート ライブラリ (appcompat) を使用して ActionBar にタブを追加すると、ActionBar が消えます -> フラグメントが穴の画面スペースを占有します。ActionBar にタブを追加しなければ、すべて問題ありません (ActionBar は表示されます)。ActionBar を常に表示するために必要なこと。

package test.appcompat;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBar.Tab;
import android.support.v7.app.ActionBarActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;


public class Main extends ActionBarActivity implements ActionBar.TabListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        final ActionBar ab = getSupportActionBar();
        ab.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        ab.addTab(ab.newTab().setText("tab 1").setTabListener(this), 0);
        ab.addTab(ab.newTab().setText("tab 2").setTabListener(this), 1);
    }

    @Override
    public void onTabReselected(Tab arg0, FragmentTransaction arg1) { }
    @Override
    public void onTabUnselected(Tab arg0, FragmentTransaction arg1) { }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        Fragment f = new MyFragment();

        Bundle args = new Bundle();
        args.putString(MyFragment.ARG_TEXT, "Tab: "+ tab.getPosition());
        f.setArguments(args);

        getSupportFragmentManager().beginTransaction()
            .replace(android.R.id.content, f)
            .commit();
    }
}

class MyFragment extends Fragment {
    public static final String ARG_TEXT = "---";

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment, container, false);
        ((TextView) v.findViewById(R.id.text))
            .setText(getArguments().getString(ARG_TEXT) + " hello");

        return v;
    }
}
