Implement Night Mode In Your Android App

The night mode function is available on many Android smartphones. This handy function allows you to apply a filter to the screen to minimize eye strain and reduce the blue light emitted by your smartphone screen . In this tutorial I will show you how to implement night/dark mode in your android application . I am going to create custom style to achieve that , you may also create more than one style using the same technique

 

Firstly We Need To Create a value Resource file and name that 

value resource file as "attrs.xml" and this file contains the 

all color attributes which help us to change the theme colors

After that make some changes in the "Style.xml" resource file 

presents in the same directory "Values" we can add new theme

for night/dark mode and add some transitions for make feel good

when we move from light theme to dark theme

After doing that we can create a layout for our activity 

"activity_main.xml" in this activity layout we use card view

to separate the content of the activity for doing that you must 

add the cardview dependency in your app level gradle file

compile 'com.android.support:cardview-v7:x.x.x'

You must place your app compact dependency version in place of "x.x.x"

After design the layout file for your android app now you have to

implement the functioning to the switch which can switch the dark

mode to light mode and light mode to the dark mode

Finally Run Your Android App
