具有顶部和底部边距的自定义按钮

Question

I need to create a layout like below.

And I worked out how to create a this layout:

How can I add top and bottom margins? And button background color? I made the button transparent by using:

android:background="@android:color/transparent"

Now how can I make button background color to light blue.

If I use custom button layout, how can I do that? I checked lots of Stackoverflow questions, but all of them concern gradient, color change on click, etc.

Thank you!

You don't want to use the transparent background color ... instead set it to the blue color you want. Then use setAlpha to make it partially transparent:

MyButton.getBackground().setAlpha(50);

To set both the border and transparent background, I think you'll have to make an XML drawable and define as the button's background:

android:background="@drawable/mybuttonbackground"

Then the drawable resource should be like this (/res/drawable/mybuttonbackground.xml):

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <shape android:shape="rectangle">
            <stroke android:width="1dp" android:color="#FF000000" />
            <solid android:color="#FFFFFF" />
        </shape>
    </item>

   <item android:top="1dp" android:bottom="1dp"> 
        <shape ="rectangle">
            <stroke android:width="1dp" android:color="#FFDDDDDD" />
            <solid android:color="#FFFFFF" />
        </shape>
   </item>
</layer-list>
