Android question: Can the tabhost be put in one of the tab?

I have some information which I want to show in a cascading style, and would prefer to show it in tab way.

So my idea is to have a TabHost embedded into one tab of another parent TabHost.

I can have one layer of TabHost working, but when I tried to add another TabHost into one of the tab, it always given an error of:

No resource found that matches the given name (at 'id' with value '@android:id/tabhostDiagnosis

Anyone faced the same problem before?

Here is my code (removed the redundant part)

<?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 a开发者_开发百科ndroid:id="@android:id/tabcontent"
            android:layout_width="fill_parent" android:layout_height="fill_parent">

            <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent" android:layout_height="fill_parent"
                android:id="@+id/Diagnosis">
                <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                    android:orientation="vertical" android:layout_width="fill_parent"
                    android:layout_height="fill_parent">

<!--  -->
                    <TabHost xmlns:android="http://schemas.android.com/apk/res/android"
                    android:id="@android:id/tabhostDiagnosis"                        
                        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/tabsDiagnosis" 
                                android:layout_width="fill_parent" android:layout_height="wrap_content" />

                            <FrameLayout android:id="@android:id/tabcontentDiagnosis"
                                android:layout_width="fill_parent" android:layout_height="fill_parent">

                            </FrameLayout>
                        </LinearLayout>
                    </TabHost>
                </LinearLayout>
            </ScrollView>


        </FrameLayout>
    </LinearLayout>
</TabHost>

I studied the source code for TabHost.

It will reference the TabWidget (or FrameLayout) directly by the R.id.x.

mTabWidget = (TabWidget) findViewById(com.android.internal.R.id.tabs);

This basically stops from having TabHost embedded into another one.

So the answer is it will not work.

Winston is correct but ...

You can initiate another activity upon tab selection which can instantiate a new TabHost / TabWidget etc.
