Question

I have this layout:

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/stat_brightness_off"
        android:layout_toLeftOf="@id/brightnessSeekBar" />

    <SeekBar
        android:id="@+id/brightnessSeekBar"
        android:layout_width="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_height="wrap_content" />

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/brightnessSeekBar"
        android:src="@drawable/stat_brightness_on" />
</RelativeLayout>

I need the SeekBar to fill all the horizontal space, unused by ImageView‘s (they are about 64*64 px). What should I do?

Use the code provided below:

<RelativeLayout 
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:src="@drawable/stat_brightness_on" />

    <SeekBar
        android:id="@+id/brightnessSeekBar"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_toLeftOf="@id/img2"
        android:layout_toRightOf="@id/img1" />

    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:src="@drawable/stat_brightness_on" />

</RelativeLayout>
