我正在使用Settings.System類，並希望顯示我的Android設備的給定參數。我是否需要訪問Settings.System類的特殊權限
AIRPLANE_MODE_ON: null
AIRPLANE_MODE_RADIOS: null
AUTO_TIME: null
FONT_SCALE: null
HAPTIC_FEEDBACK_ENABLED: null
MODE_RINGER: null
MODE_RINGER_STREAMS_AFFECTED: null
MUTE_STREAMS_AFFECTED: null
NOTIFICATION_SOUND: null
RINGTONE: null
SCREEN_BRIGHTNESS: null
SCREEN_BRIGHTNESS_MODE: null
SCREEN_OFF_TIMEOUT: null
STAY_ON_WHILE_PLUGGED_IN: null
它顯示每個參數爲空。下面是我的部分代碼：
Log.d("Setting",Settings.Secure.getString(mcontex.getContentResolver(),Settings.System.AIRPLANE_MODE_ON.toString()));
Log.d("Setting",Settings.Secure.getString(mcontex.getContentResolver(),Settings.System.AIRPLANE_MODE_RADIOS.toString()))
任何建議，歡迎.. :)
