Question

I am quite new to Android dev, but not Java dev, so doing the logic behind a button is no issue, but styling it is not as easy as css. I have read a couple tutorials on shapes / styles so I kind of know how to do the custom borders and round corners, but I was hoping to see some really good quality examples, like the buttons on the Twitter app https://i.stack.imgur.com/Gip2s.png or the ‘debossed’ ones on the facebook app.

What I suppose I am really interested in, are using shadows to create effects. Are these done with images, or can you style this in the app?

thanks

Answer 1

for rounded corners create a shape drawable eg. ronded_corner.xml and the angle must be a multiple of 45 degree

<?xml version="1.0" encoding="UTF-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
     android:shape="rectangle"> 
     <gradient android:startColor="#SomeGradientBeginColor" android:endColor="#SomeGradientEndColor" 
            android:angle="225"/> 

    <corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp" 
     android:topLeftRadius="7dp" android:topRightRadius="7dp"/> 
</shape> 

then set this Background by android:background:@drawable/ronded_corner
