• Change the hard-coded value of the Spinner width to wrap_content
• add the below theme to the spinner

So, your spinner :

<Spinner
    android_id="@+id/directory_list"
    android_layout_width="wrap_content"
    android_layout_height="?actionBarSize"
    android_theme="@android:style/Theme.Holo.Light.DarkActionBar"
    android_spinnerMode="dropdown" />

I want to remove padding between text and icon,
iattach image below

This is layout code

   <LinearLayout
        android_layout_width="fill_parent"
        android_orientation="horizontal"
        android_layout_height="?actionBarSize">

        <ImageButton
            android_id="@+id/bt_close"
            android_background="?selectableItemBackgroundBorderless"
            android_layout_width="?actionBarSize"
            android_layout_height="?actionBarSize"
            android_tint="@color/grey_60"
            app_srcCompat="@drawable/ic_chevron_left"/>

        <Spinner
            android_layout_width="150dp"
            android_layout_height="?actionBarSize"
            android_spinnerMode="dropdown"
            android_id="@+id/directory_list"
            />

        <View
            android_layout_width="0dp"
            android_layout_height="0dp"
            android_layout_weight="1.0"
            />

        <ImageButton
            android_background="?selectableItemBackgroundBorderless"
            android_layout_width="?actionBarSize"
            android_layout_height="?actionBarSize"
            android_tint="@color/grey_60"
            app_srcCompat="@drawable/ic_done"
            android_id="@+id/done"
            />

    </LinearLayout>
