<LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"

        android:paddingLeft="20dp"
        android:paddingRight="20dp"
        android:paddingTop="5dp" >

        <Button
            android:layout_width="fill_parent"
            android:layout_height="match_parent"
            android:background="@drawable/fb_bg"
            android:text="Login with Facebook"
            android:drawableLeft="@drawable/fb_icon"
            android:layout_marginBottom="5dp"
            android:drawablePadding="0dp"
            android:textColor="@android:color/background_light"
            android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>

fb_icon and fb_bg ( size of both the drawables are same - 40 x 40 )

Answer 1

Remove padding of parent and margin of Button

Use this

<LinearLayout
    android:id="@+id/linearLayout1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:orientation="vertical"
    android:paddingLeft="20dp"
    android:paddingRight="20dp" >

    <Button
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:background="@drawable/fb_bg"
        android:text="Login with Facebook"
        android:drawableLeft="@drawable/fb_icon"
        android:drawablePadding="0dp"
        android:textColor="@android:color/background_light"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>
