Android 设置亮度，安卓面试没项目经验

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

} catch (Settings.SettingNotFoundException e) {

e.printStackTrace();

}

return automicBrightness;

}

//停止亮度调节

public static void stopAutoBrightness(Activity activity){

//设置Activity亮度手工模式

Settings.System.putInt(activity.getContentResolver(), Settings.System.SCREEN_BRIGHTNESS,

Settings.System.SCREEN_BRIGHTNESS_MODE_MANUAL);

}

接下来获取手机当前亮度,要通过Context来使用内容提供器getContentResolver()

再用android.provider.Settings.System.getInt(

resolver,Settings.System.SCREEN_BRIGHTNESS)来得到亮度

//获取亮度

public static int getScreenBrightness(Activity activity){

int nowBrightnessValue = 0; //当前亮度

//通过ContentResolver接口访问provider数据，获得实例

ContentResolver resolver = activity.getContentResolver();

try {

nowBrightne
