Android : TextView is not updated within RelativeLayout

I'm developing a custom camera app. CameraPreview takes a part of the screen, and the rest of the screen on the rightis allocated for control panel.

Now, when I change the shooting parameters, the text view and toggle views on the control panels are not updated. I guess this is because of the camera, but I have no clue what to do.

This is a screen shot:

My layout looks like this:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<RelativeLayout
android:id="@+id/total_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >


<FrameLayout
android:id="@+id/gen_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#AA8888">


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

</FrameLayout> <!--  GEN_VIEW END -->


<LinearLayout
android:id="@+id/control_panel"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:orientation="vertical" >

<TextView
android:id="@+id/header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:text="Pocket Viewfinder" />

<TextView
android:id="@+id/viewAngle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:text="@string/hello"
android:textSize="10sp" />

<TextView
android:id="@+id/widerWarning"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:text="@string/wWarning" />

<ToggleButton
android:id="@+id/booster_toggle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:textOff="@string/booster_off"
android:textOn="@string/booster_on" />


</LinearLayout>

</RelativeLayout> <!--  TOTAL_VIEW END -->

What I am doing wrong? THNX
