removing whitespace in android Switch which is devoted to text

问题

(we all know) There are three parts in android Switch Widget ... Text - Thumb - Track.
My question is how can we completely remove this text part if we don't want to use any text because it's ruining the balance of the layout

回答1:

You simply have to not provide any text:

    <Switch
        android:id="@+id/switch1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

回答2:

Use negative margin for the switch as follows and see if it works:

 <Switch
        android:id="@+id/switch1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="-10dp" />

I know some people consider it a bad practice to use negative margin but right it seems to be the easiest way.

You can set margin programmatically as well based on device type.
