Problema con tabwidget

Ciao a tutti!
Non capisco perchè questo codice mi visualizza solo un'oggetto (il primo nel codice xml)!

Codice ANote.java:

package com.hackme.ANote; import android.app.TabActivity; import android.content.Intent; import android.os.Bundle; import android.widget.Button; import android.widget.EditText; import android.widget.TabHost; import android.widget.ViewFlipper; public class ANote extends TabActivity { Button BottoneSalva,BottoneClear; EditText Text1,Text2; ViewFlipper Flipper; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Flipper = (ViewFlipper)findViewById(R.id.layout_tab_one); TabHost mTabHost = getTabHost(); mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("Add Note").setContent(R.id.layout_tab_one)); mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("Note List").setContent(R.id.layout_tab_two)); mTabHost.setCurrentTab(0); } }

Codice main.xml:
<?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ViewFlipper android:id="@+id/layout_tab_one" android:layout_width="fill_parent" android:layout_height="fill_parent"> <EditText android:id="@+id/Text1" android:layout_width="fill_parent" android:layout_height="240sp" android:text="" android:gravity="left" android:hint="insert the text" /> <Button android:id="@+id/Button1" android:layout_width="fill_parent" android:layout_height="60sp" android:text="save" android:gravity="left" /> </ViewFlipper> <ViewFlipper android:id="@+id/layout_tab_two" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/tabone1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is a tab two" /> <EditText android:id="@+id/Text2" android:layout_width="fill_parent" android:layout_height="240sp" android:text="" android:gravity="left" android:hint="insert the text" /> </ViewFlipper> </FrameLayout> </LinearLayout> </TabHost>
