Question

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?

Answer 1

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 -->
