Answer 1

it's very simple:

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);//  set status text dark
getWindow().setStatusBarColor(ContextCompat.getColor(BookReaderActivity.this,R.color.white));// set status background white

and vice versa:

getWindow().setStatusBarColor(ContextCompat.getColor(BookReaderActivity.this, R.color.black));
View decorView = getWindow().getDecorView(); //set status background black 
decorView.setSystemUiVisibility(decorView.getSystemUiVisibility() & ~View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR); //set status text  light

Answer 2

I'm not sure what API level your trying to target, but if you can use API 23 specific stuff, you can add the following to your AppTheme styles.xml:

<item name="android:statusBarColor">@color/colorPrimaryDark</item>
<item name="android:windowLightStatusBar">true</item>

when android:windowLightStatusBar is set to true, status bar text color will be able to be seen when the status bar color is white, and vice-versa when android:windowLightStatusBar is set to false, status bar text color will be designed to be seen when the status bar color is dark.

Example:

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <!-- Status bar stuff. -->
    <item name="android:statusBarColor">@color/colorPrimaryDark</item>
    <item name="android:windowLightStatusBar">true</item> 
</style>
