android how can i force the button row to stay the same size

looking at the pictures maybe it's obvious what the problem is.

The button row insist on getting to big in portrait mood.

Remove the

android:layout_below="@+id/cb_delete_files_option_activity"

then the

@+id/cb_delete_files_option_activity

checkbox is not visible in landscape mood.

anyone have some ide?

In the RelativeLayout, it should be android:layout_height="wrap_content", NOT fill_parent.

Wrap your entire LinearLayout containing the buttons inside a NEW RelativeLayout, placing the android:layout_below="@+id/cb_delete_files_option_activity" inside it instead of in the LinearLayout:

    <!-- the rest of your xml -->
    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/cb_delete_files_option_activity"
    >
        <LinearLayout android:id="@+id/linerLayout_send_button_row"
            android:orientation="horizontal"
            android:background="@android:drawable/bottom_bar" 
            android:paddingLeft="4.0dip"
            android:paddingTop="5.0dip" 
            android:paddingRight="4.0dip"
            android:paddingBottom="1.0dip" 
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            >
            <Button android:id="@+id/btn_send_activity_send_nr_two"
                android:layout_width="0.0dip"
                android:layout_height="fill_parent"
                android:text="Send"
                android:layout_weight="1.0"

            />
            <Button android:id="@+id/btn_more_activity_send_nr_two"
                android:layout_width="0.0dip"
                android:layout_height="fill_parent"
                android:text="More"
                android:layout_weight="1.0"

            />
        </LinearLayout>
    </RelativeLayout>
    <!-- the rest of your xml -->

Use android:layout_height="wrap_content" for both buttons and delete android:layout_below="@+id/cb_delete_files_option_activity" from your linear layout.
