Does anyone know what this error means for Android tabs?

Question

I am trying to try an online tutorial and want to put a tab in the xml layout. I have changes: from Activity to TabActivity. In the xml layout design view, I have the following.

Error during the process after inflation: TabHost requires TabWidget with identifier "android: id / tabs". View found with id 'tabs' is 'com.android.layoutlib.bridge.MockView' Could not find the following classes:

I was looking for a solution, but none of them were fixed, but I found it in another language. I tried using google translator but not very useful.

Someone can get the tab function.

I am using Android 2.2 Api and developing using the Eclipse IDE

Answer 1

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

The user suggested switching the build target to 1.6, and the problem goes away. Obviously a temporary fix.

Answer 2

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 tutorial for more information.

Answer 3

Do you have TabWidget with id android: id / tabs, since the error message tells you what you need?

As stated above Quick Fix: just change the API (top left of XML) graphical representation) to 3.0, and you can see it

Switch to Android 3.0 or 3.1. You can find this dropdown at the top right
