Hey how do you render the Correct the following errors in

https://storage.googleapis.com/material-design/publish/material_v_11/assets/0Bzhp5Z4wHba3dEZTUF9idzBHMWc/patterns_errors_userinput19.png▾

?

[gildor]

Just use TextView + background + text color

[bamdmux]

Have it hidden, and make it visible if there were errors

[robinchew]

Oh ok, will there be fancy animation that comes for free from hiding n showing?

[robinchew]

Is there code that controls elevation? Cos the grey bit looks deeper

[gildor]

It depends on what animation do you want to get. For example easiest soltion is just use Transition API from android.support.transition

[robinchew]

Alright thanks the help

[gildor]

effect of “deep” can be done if you just add this “shadow” to bottom of view background

[robinchew]

Is there a shadow property for all views?

[bamdmux]

In material design you can control elevation

[bamdmux]

https://developer.android.com/training/material/shadows-clipping.html

[bamdmux]

theres a code sample

[bamdmux]

and also if you want another sample for what @gildor said:

[robinchew]

Awesome thanks everyone

[bamdmux]

The training pages of developer.android have a lot of samples implementing the design guidelines

[gildor]

You can try to play with elevation, but it works only starting from API 21 or only for CardView

[robinchew]

Im new to android studio so i dont know how easy it is to setup projects downloaded from the net

[gildor]

There are tons of tutorials in Google, including official ones

[robinchew]

Also, im not using XML.

[robinchew]

Im building views programmatically

[gildor]

You still can use all mentioned approaches

[gildor]

btw why do you decide to build view programmatically?

[robinchew]

Im a masochist

[robinchew]

Also Flexibility

[robinchew]

I can easily add and remove views depending on context.

[robinchew]

The UI gets the power of a programming language (kotlin, java)

[robinchew]

Instead of XML

[bamdmux]

Then I suggest you take a look at Anko: https://github.com/Kotlin/anko/wiki/Anko-Layouts

[robinchew]

I was interested in that, i also looked into https://github.com/zserge/anvil
