一、需求

由于Android系统碎片化比较严重,因此为了统一调整状态栏颜色,因此实现一个工具类相当必要。

 

注意:本类支持Android 5.0 以上的版本,android 5.0之前的兼容性太差,因此不做处理。

public class StatusBarManager {

    private int is_MIUI_platform = -1; //初始值是-1,0表示检测过不是改平台,1表示检测过时该平台
    private int is_MEIZU_platform = -1; //初始值是-1,0表示检测过不是改平台,1表示检测过时该平台


    public static final int UI_FIT_SYSTEM_WINDOW =  0x01; //全屏模式
    public static final int UI_FIT_ACTIVITY =  0x00; //着色模式
    private static ColorDrawable colorDrawable;

    protected StatusBarManager(){

    }

        if (activity == null) return null;

    }
