java - Android tabhost 问题...包含代码

Question

当我尝试启动包含 tabhost 的 Activity 时出现以下错误。

08-25 16:51:42.551: ERROR/AndroidRuntime(27863): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.paratransit/com.paratransit.jobDialog}: java.lang.RuntimeException: Could not create tab content because could not find view with id 2131165185

这是我的代码。谁能帮忙？

Java

public Class jobDialog extends TabActivity {

    TabHost tabs;
 int jobCurrentTab = -1;

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

        Bundle extras = getIntent().getExtras();
        setContentView(R.layout.job_dialog);

     tabs = getTabHost();
        tabs.setup();
     setupTabs();
 }

 public void setupTabs()
 {     
      TabSpec tspec1 = tabs.newTabSpec("First Tab");
      tspec1.setIndicator("Summary", getResources().getDrawable(R.drawable.tab_main)).setContent(R.id.jobDetail1);   
      tabs.addTab(tspec1);
      TabSpec tspec2 = tabs.newTabSpec("Second Tab");
      tspec2.setIndicator("Details", getResources().getDrawable(R.drawable.tab_message)).setContent(R.id.jobDetail2);
      tabs.addTab(tspec2);
      TabSpec tspec3 = tabs.newTabSpec("Third Tab");
      tspec3.setIndicator("Notes", getResources().getDrawable(R.drawable.tab_jobs)).setContent(R.id.jobDetail3);
      tabs.addTab(tspec3);

  </LinearLayout>  

       <LinearLayout
   android:id="@+id/jobDetail2"
      android:orientation="vertical"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent" >   

  </LinearLayout>  

  <LinearLayout
   android:id="@+id/jobDetail3"
      android:orientation="vertical"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent" >   

  </LinearLayout>

    </LinearLayout>
</TabHost>

我认为 3 个线性布局，jobDetail1->3 应该在 FrameLayout xml 元素中。 FrameLayout 的要点是所有 View 都在彼此之上，因此选项卡管理器可以决定显示哪个 View 。
