The Tab1.java from API Demo has exception
<p>I don't know why.All my Tab programs have exception.Even from API Demo.</p>

<h2>Here is the code:</h2>

<p>package com.example.android.apis.view;</p>

<p>import android.app.TabActivity;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
import android.view.LayoutInflater;
import android.view.View;</p>

<p>public class Tab1 extends TabActivity {<br>
 @Override<br>
 protected void onCreate(Bundle savedInstanceState) 
 {<br>
  super.onCreate(savedInstanceState);<br>
  TabHost tabHost = getTabHost();<br>
  LayoutInflater.from(this).inflate(R.layout.main,tabHost.getTabContentView(), true);<br>
  tabHost.addTab(tabHost.newTabSpec("tab1")<br>
    .setIndicator("tab1")<br>
    .setContent(R.id.view1));<br>
  tabHost.addTab(tabHost.newTabSpec("tab2")<br>
    .setIndicator("tab2")<br>
    .setContent(R.id.view2));<br>
  tabHost.addTab(tabHost.newTabSpec("tab3")<br>
    .setIndicator("tab3")<br>
    .setContent(R.id.view3));<br>
 }
}</p>
