Anyone know what this error mean for android tabs?

问题

I am trying to try out the tutorial online and wanted to put the tab to the layout xml. I have change the extends from Activity to TabActivity. In the design view of the layout xml, I have the below.

Error during post inflation process: TabHost requires a TabWidget with id "android:id/tabs". View found with id 'tabs' is 'com.android.layoutlib.bridge.MockView' The following classes could not be found:

I have looked for solution but none of them fixed except I found one in different language. I tried using the translator on google but not so helpful.

Does anyone manage to get the tabs function.

I am using Android 2.2 Api and develop with an eclipse IDE

Known bug http://code.google.com/p/android/issues/detail?id=13092

A user suggested to switch build target to 1.6 and the issue goes away. Obviously a temporary fix.

You need a layout like this:

<?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"
        android:padding="5dp">
        <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"
            android:padding="5dp" />
    </LinearLayout>
</TabHost>

See the Tab Layout tutorial for more info.

Do you have a TabWidget with id android:id/tabs as the error message tells you you need?

Switch to android Target 3.0 or 3.1. You can find that drop down list on the top right side

As stated above Quick Fix: Just change the API Target (top left of XML graphical view) to 3.0 and you can see it
