应用程序在后台时如何更改状态栏颜色？

Question

I am able to change the status bar color to green but when home button is clicked when app is in background, status bar goes back to its original color. I want to retain the status bar color even when the app is in background. Like status bar is green when there is a call connected.

This is my code to change the status color.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().setStatusBarColor(
        ContextCompat.getColor(context,R.color.colorAccent)); 
}

Answer 1

The onPause() and onResume() methods are called when the application is brought to the background and into the foreground again. However, they are also called when the application is started for the first time and before it is killed.

There isn't any direct approach to get the application status while in the background or foreground, but even I have faced this issue and found the solution with onWindowFocusChanged and onStop . For more details please check this.

Happy coding!!
