哎,本来认为是应该结束了,但是悲剧得是,既然像刚才那样设置的话,只能在当前的activity中有作用,一段退出的时候,会发现毫无作用,悲剧,原来是忘记了保存了。汗!
/**
* 保存亮度设置状态

* @param resolver
* @param brightness
*/
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);
}
这回该差不多了吧!
