Preface:
Android development, for the status bar modification, it is not friendly, there is no API to use, not as convenient as ios. But UI likes to be ios only. No way. All kinds of source code, write reflection. It really hurts.
Requirement scenarios:
When the Toolbar and status bar need to be white or light-colored (e.g., simple book), the status bar will be hard to read due to the light-style Theme, font, and ICONS that are white. If I change it to black, it will be very harmonious.
1. Modify the status bar color:
To change the color of the statusbar, check out this article portal: achieving the statusbar gradient effect is actually quite simple
What the portal does:
This method achieves color-changing status bar with no black background.

Using the full screen mode to achieve the following effect (QQ effect):
Clear translucent black background.

2. Modify the status bar font:

StatusBarUtil.setStatusBarLightMode(getWindow());
Copy the codeEffect:
Problems:
1. The statusbar background color has changed to colorPrimaryDark by default, but my configuration is white (see the code at the end).
Analyze the reasons:
setSystemUiVisibility() will refresh the view's property configuration. Since statusbar uses the colorPrimaryDark property by default. So the color will go back to the default colorCopy the code
In this case, the method of setting the background in step 1 is invalid.
private void initStatusBar() {
if (statusBarView == null) {
int identifier = getResources().getIdentifier("statusBarBackground"."id"."android");
statusBarView = getWindow().findViewById(identifier);
}
if (statusBarView != null) {
statusBarView.setBackgroundResource(MVPConfig.statusDrawable);
}
}
Copy the codeReason: When the passed resiD is the same, the background color will not be set again.
Solutions:
private void initStatusBar() {
if (statusBarView == null) {
int identifier = getResources().getIdentifier("statusBarBackground"."id"."android");
statusBarView = getWindow().findViewById(identifier);
}
if(statusBarView ! = null) { statusBarView.setBackgroundDrawable(null); // Set the background to null before setting; //statusBarView.setBackgroundResource(0); / / this can also be statusBarView. SetBackgroundResource (MVPConfig. StatusDrawable); }}Copy the codeModified effect:

- Under 6.0,5.0 native system can not change the font color, used a more clever way, set to translucent gray.

} else{/ / 5.0if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP_MR1) {
MVPConfig.statusDrawable = Color.parseColor("#33ffffff"); }}}Copy the code- Since you modify the background of the StatusBarView in the Window directly, and frgament depends on the Activity, the statusbar is not very useful when the Activity and Fragment jump directly. For example, if the activity is blue, the fragment needs to be white, and the fragment needs to change the color of the status bar through the window. It’s a bit of a problem.
