Why is Android TabHost stealing focus from a TextView?

Question

I have an application using the following layout :

alt text http://img15.imageshack.us/img15/238/screenshot003xbo.png

When the app starts, the focus is on the first TextView, but if you try to type any letter in it, the focus goes directly to the tabs. It seems that I am not the only one fighting with this issue, and maybe this is related to the following:

Anyway, have you any idea of why that happens? And of course, any workaround would be appreciated.

I post the code below to avoid overloading the question :

The XML :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent">

           android:layout_weight="50" >

        <LinearLayout android:orientation="vertical"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content">

            <TextView android:layout_width="wrap_content"
                android:layout_height="wrap_content" 
                android:text="@string/title" 
                android:textStyle="bold" />

            <EditText android:id="@+id/title" 
              android:layout_width="fill_parent"
                android:layout_height="fill_parent" />

        </LinearLayout>

        <TabHost android:id="@+id/edit_item_tab_host"

            <FrameLayout
              android:id="@android:id/tabcontent"

                            android:text="date" 
                             android:textStyle="bold" />

                </LinearLayout>

                <LinearLayout

                    android:layout_height="fill_parent"

                <TextView android:layout_width="wrap_content"
                            android:layout_height="wrap_content" 
                            android:text="lieu" 
                             android:textStyle="bold" />

                </LinearLayout>

                <LinearLayout
                   android:id="@+id/edit_item_text_tab"
                   android:orientation="vertical"

                        android:scrollbars="vertical" />

                </LinearLayout>

            </FrameLayout>

        </TabHost>

    </LinearLayout>

    <!-- Bottom pannel with "add item" button -->
    <LinearLayout 
          android:padding="5px"
          android:orientation="horizontal" 
          android:layout_weight="1"
          android:id="@+id/task_edit_panel"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:background="#E7E7E7" >

          <!--  Let the height set to fill_parent until we find a better way for the layout  -->
          <Button android:id="@+id/item_edit_ok_button"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="bottom"
                android:text="@string/ok"
                style="?android:attr/buttonStyleSmall"
                android:layout_weight="1" />

           <Button android:id="@+id/item_edit_cancel_button"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="bottom"
                android:text="@string/cancel"
                style="?android:attr/buttonStyleSmall"
                android:layout_weight="1" />

    </LinearLayout>

</LinearLayout>

And the Java code :

    TabHost tab_host = (TabHost) findViewById(R.id.edit_item_tab_host);
    // don't forget this setup before adding tabs from a tabhost using a xml view or you'll get an nullpointer exception
    tab_host.setup(); 

    TabSpec ts1 = tab_host.newTabSpec("TAB_DATE");
    ts1.setIndicator(getString(R.string.when), getResources().getDrawable(R.drawable.ic_dialog_time));
    ts1.setContent(R.id.edit_item_date_tab);
    tab_host.addTab(ts1);

    TabSpec ts2 = tab_host.newTabSpec("TAB_GEO");
    ts2.setIndicator(getString(R.string.where),  getResources().getDrawable(R.drawable.ic_dialog_map));
    ts2.setContent(R.id.edit_item_geocontext_tab);
    tab_host.addTab(ts2);

    TabSpec ts3 = tab_host.newTabSpec("TAB_TEXT");
    ts3.setIndicator(getString(R.string.what),  getResources().getDrawable(R.drawable.ic_menu_edit));
    ts3.setContent(R.id.edit_item_text_tab);
    tab_host.addTab(ts3);

    tab_host.setCurrentTab(0);

Well, definitly a bug : http://code.google.com/p/android/issues/detail?id=2516.

Hope it will be fixed in the next release because this is a really anoying issues for complex apps with an advanced layout.
