Android 12 上調(diào)用系統(tǒng)的護(hù)眼模式和麗色系統(tǒng)

護(hù)眼模式,可以直接使用反射的方式調(diào)用

    public static final String ColorDisplayManager="android.hardware.display.ColorDisplayManager";

    /**
     * 設(shè)置護(hù)眼模式
     * @param activated 開關(guān)
     */
    public static boolean setColorDisplayManager(boolean activated){
        boolean ac=false;
        GDLog.e("set activated="+activated);
        try {
            @SuppressLint("PrivateApi") Class<?> colorDisplayManager = Class.forName(ColorDisplayManager);
            Object o=colorDisplayManager.newInstance();
            /*GDLog.e("setColorDisplayManager2");
            Method[] methods= colorDisplayManager.getMethods();
            for (Method m:methods) {
                GDLog.e("m:"+m.getName()+"---");
                Class<?>[] classes= m.getParameterTypes();
                for (Class c:classes) {
                    GDLog.e("c:"+c.getName());
                }
            }*/
            //忽略訪問權(quán)限修飾符,獲取方法
            Method setNightDisplayActivated = o.getClass().getDeclaredMethod("setNightDisplayActivated",boolean.class);
            setNightDisplayActivated.setAccessible(true);
            ac= (boolean) setNightDisplayActivated.invoke(o,activated);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return ac;
    }

    public static boolean isNightDisplayActivated(){
        boolean activated=false;
        try {
            @SuppressLint("PrivateApi") Class<?> colorDisplayManager = Class.forName(ColorDisplayManager);
            Object o=colorDisplayManager.newInstance();
            //忽略訪問權(quán)限修飾符,獲取方法
            Method setNightDisplayActivated = o.getClass().getDeclaredMethod("isNightDisplayActivated",null);
            setNightDisplayActivated.setAccessible(true);
            activated= (boolean) setNightDisplayActivated.invoke(o);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return activated;
    }

麗色系統(tǒng)照弥，這塊代碼不在framework 里面弥虐，所以不能直接反射獲取消恍，調(diào)用需要導(dǎo)入softwinner.display.output.jar 包
jar包下載路徑
提取碼:rg56

private DefaultDisplayOutputManager displayOutputManager=new DefaultDisplayOutputManager();
//麗色系統(tǒng)
displayOutputManager.setDisplayEnhanceMode(0,displayOutputManager.getDisplayEnhanceMode(0)==1?0:1);
//演示模式更胖，只對半屏有效
displayOutputManager.setDisplayEnhanceMode(0,displayOutputManager.getDisplayEnhanceMode(0)==2?0:2);
//取值范圍 <integer name="config_HSL_max_range">10</integer>
//                setDisplaySaturation 飽和度
//                setDisplayBright 亮度
//                setDisplayContrast 對比度

private static final int COLOR_TEMPERATURE_SCALE_MAX = 100; // 100 percentage
//                setColorTemperature 色溫     
//                getColorTemperature
//黑白模式
displayOutputManager.setBlackWhiteMode(0,displayOutputManager.getBlackWhiteMode(0)?false:true);
//閱讀模式
displayOutputManager.setReadingMode(0,displayOutputManager.getReadingMode(0)?false:true);
