Answer 1

int brightnessmode;

getBrightMode();

if(brightnessmode==1){
//below code will off the auto mode

                android.provider.Settings.System.putInt(contentresolver, Settings.System.SCREEN_BRIGHTNESS_MODE,
                        Settings.System.SCREEN_BRIGHTNESS_MODE_MANUAL);

//Here perform any action you want
}

if(brightnessmode==0){
//below code will on the auto mode

                android.provider.Settings.System.putInt(contentresolver, Settings.System.SCREEN_BRIGHTNESS_MODE,
                        Settings.System.SCREEN_BRIGHTNESS_MODE_AUTOMATIC);
//Here perform any action you want
}

//This method will give brightness mode
//if brigthnessmode=0 means Auto mode is currently off
//if brightnessmode=1 means Auto mode is currently on
protected void getBrightMode() {
// TODO Auto-generated method stub
    try {
        brightnessmode = System.getInt(contentresolver, System.SCREEN_BRIGHTNESS_MODE);
    } catch (Exception e) {
        Log.d("tag", e.toString());
    }
}

Answer 2

Settings.System.putInt(context.getContentResolver(), Settings.System.SCREEN_BRIGHTNESS_MODE, Settings.System.SCREEN_BRIGHTNESS_MODE_AUTOMATIC);

使用SCREEN_BRIGHTNESS_MODE模式http://developer.android.com/reference/android/provider/Settings.System.html

您应该能够从Settings.System中读取此内容，查找SCREEN_BRIGHTNESS_MODE
