I have a `editext` which I would like to show as drop down. SO for that I have `background.xml` file:

```
<?xml version="1.0" encoding="utf-8" ?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">

  <item>
    <layer-list>
      <item>
        <shape>
          <solid android:color="#ffffff" />
          <stroke android:width="1dp" android:color="#000000" />
          <padding android:bottom="3dp" android:left="3dp" android:right="3dp" android:top="3dp" />
        </shape>
      </item>
      <item>
        <bitmap android:gravity="right" android:src="@drawable/ic_arrow_drop_down" />
      </item>
    </layer-list>
  </item>

</selector>

```

And added that as background for my edittext. This is what I get:
[![enter image description here](https://i.stack.imgur.com/eG2r6.jpg)](https://i.stack.imgur.com/eG2r6.jpg)

As you can see there is slight gap between the image and editext border. I would like to make my edittext like this:
[![enter image description here](https://i.stack.imgur.com/e8ych.jpg)](https://i.stack.imgur.com/e8ych.jpg)

How can I achieve this?
