Android Color status bar

The app you've been thinking about making yourself look good. So add a status bar to your app that can change color. I did not do the downward compatibility ... Only mobile phone version is 4.4 and above the use of mobile phones. Someone on the internet is called immersive, and I think the blogger's explanation is right here:
Android Implementation Color Status bar

A particularly important step:
Activity must use a theme!

android:theme="@style/AppTheme.NoActionBar"

Here I am using the default theme to see what you need to use.

1, first in the activity's OnCreate method, set the title bar to Transparent:

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {            getWindow().setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,         WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);        }

2, and then to keep your top control moving up, you need to add the following two sentences to the top control of the layout file:

 android:fitsSystemWindows="true" android:clipToPadding="true"

3, then if the background color of your top control is blue, then your title bar will also turn blue:
You can look at the following:

Here is a simple book on the Great God wrote a tool Class I used very good ... Share to everyone. Also thank the great God for sharing:
Need to download an open Source Library yourself Systembartint
Have time I also want to this open source library source code to look, study!

This tool class specific function of the author notes are also very detailed!
I wrote a small demo, need to download to see ~
