    Manage Layout Inside a Horizontal Oriented Radiogroup

    I am using a TableLayout with TableRows as my main activity.

    Inside the TableLayout is a Radio Group containing 2 Radio Buttons inside the activity (the Radio Group being inside a table row). I want to be able to align the rightmost radio button to the right edge screen, so the "gap" is between the left radio button and right button (instead of after the right radio button). i.e.

    So instead of having
    | (x) (x) gap |
    I will have
    |(x) gap (x)|

    where (x) are the Radio Buttons and | are the edges of the screen

    I can use gravity (center_horizontal) to put both the buttons in the middle (i.e. | gap (x)(x) gap|) however I can't seem to be able to split them the way I want as said before

    All you need to evenly space an arbitrary number of buttons horizontally across the screen:

    RadioGroup has to have androidrientation="horizontal" & android:layout_width="fill_parent"
    Each radio button has to have android:layout_weight="1", except the rightmost button (to make it line up on the right edge of the screen)!

    This took me hours to figure out.

    Here is some example code, with a bonus of two text labels and the right and left edges of the screen, for a survey app.
    Code:
    <RadioGroup
        android:id="@+id/radio_group"
        android:orientation="horizontal"
        android:layout_below="@id/question" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:visibility="gone"
    >
        <RadioButton
            android:id="@+id/strong_disagree_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="1"
        />
        <RadioButton
            android:id="@+id/disagree_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="@string/disagree"
        />
        <RadioButton
            android:id="@+id/neutral_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="@string/neutral"
        />
        <RadioButton
            android:id="@+id/agree_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="@string/agree"
        />
        <RadioButton
            android:id="@+id/strong_agree_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="5"
        />
    </RadioGroup>
    <TextView
        android:id="@+id/disagree_label"
        android:text="@string/strongly_disagree_txt"
        android:layout_below="@id/radio_group" 
        style="@style/TextAppearance"
        android:visibility="gone"
        />
    <TextView
        android:id="@+id/agree_label"
        android:text="@string/strongly_agree_txt"
        android:layout_below="@id/radio_group" 
        android:layout_alignParentRight="true" 
        style="@style/TextAppearance"
        android:layout_width="wrap_content"
        android:visibility="gone"
        />
