阅读更多关于 Android Galaxy S4 — Activity that is visible over lock screen

问题 A few years ago, I wrote an alarm app that worked on Android 2, and I'm now trying to upgrade it to work on Android 4. Specifically, on the Samsung Galaxy S4. On Android 2, if the phone was sleeping, it would wake the phone up and display a "Snooze or Dismiss" screen over the lock screen. On Android 4, it wakes the phone up, but you have to unlock it, then open the notifications area, then click the alarm's notification, before you can hit "Dismiss." I have always been using this code to do

Disable the notification panel from being pulled down

阅读更多关于 Disable the notification panel from being pulled down

I am working on a lockscreen app and I need to disable the ability to pull down the notification/status bar at the top of the screen. There is an app called Holo Locker and what this app does is when the user pulls down from the top of the screen, it just sets the bar back up to the top of the screen and making it impossible to pull the drawer down. I have no idea where to start. Any help would be great! Thanks! Vikram This is possible using reflection. There are plenty of problems though. There's no way to check if the notification panel is open, or opening. So, we'll have to rely on Activity

I need to create a simple notification which will be shown in notification bar along with the sound and icon if possible?

You can even use features that are available with Android 4.1. If your app runs on devices with Android >=4.1 the new features will be used, if run on Android <4.1 the notification will be

How can I programmatically open/close notifications in Android?

阅读更多关于 How can I programmatically open/close notifications in Android?

问题 I\'ve searched everywhere, but can\'t find anything in the SDK or on Google on how to do this. I know it\'s possible because all the custom launchers are able to do it via a button press (LauncherPro, ADW, etc). Thanks. 回答1: You can programmatically close the notification drawer by broadcasting an ACTION_CLOSE_SYSTEM_DIALOGS intent. This causes "temporary system dialogs" to be dismissed. From the documentation: Some examples of temporary system dialogs are the notification window-shade and

How to detect when the notification/system bar is opened

阅读更多关于 How to detect when the notification/system bar is opened

问题 I needed to know when the system/notification bar gets opened in my app, and I couldn\'t find any real solutions, so I hacked something together which seems to work pretty well. 回答1: Before I big with the implementation, I will give a brief explanation of my (very hacky) logic. When an Activity is no longer visible to the user for any reason, onWindowFocusChanged(..) gets invoked. However, onStop() only gets invoked when the Activity is no longer visible to the user by going to the background
