Android 螢幕亮度調節（2.0以後出現亮度自動調節）如何開啟、關閉亮度自動調節

public static boolean isAutoBrightness(ContentResolver aContentResolver) {

        boolean automicBrightness = false;

        try {

            automicBrightness = Settings.System.getInt(aContentResolver,

                    Settings.System.SCREEN_BRIGHTNESS_MODE) == Settings.System.SCREEN_BRIGHTNESS_MODE_AUTOMATIC;

        } catch (SettingNotFoundException e) {

            e.printStackTrace();

        }

        return automicBrightness;

    }

/** * 停止自動亮度調節 */ public static void stopAutoBrightness(Activity activity) { Settings.System.putInt(activity.getContentResolver(), Settings.System.SCREEN_BRIGHTNESS_MODE, Settings.System.SCREEN_BRIGHTNESS_MODE_MANUAL); } /** * 開啟亮度自動調節 * * @param activity */ public static void startAutoBrightness(Activity activity) { Settings.System.putInt(activity.getContentResolver(), Settings.System.SCREEN_BRIGHTNESS_MODE, Settings.System.SCREEN_BRIGHTNESS_MODE_AUTOMATIC); } /** * 儲存亮度設定狀态 */ public static void saveBrightness(ContentResolver resolver, int brightness) { Uri uri = android.provider.Settings.System .getUriFor("screen_brightness"); android.provider.Settings.System.putInt(resolver, "screen_brightness", brightness); // resolver.registerContentObserver(uri, true, myContentObserver); resolver.notifyChange(uri, null); }
