我有一个BlackBerry应用程序在后台运行，需要知道系统何时启动未接来电系统对话框，并在没有用户干预的情况下以编程方式关闭它。我可以这样做吗？

I have a BlackBerry app running in the background that needs to know when a "Missed call" system dialog is brought up by the system, and programmatically close it without user intervention. How can I do that?

几乎可以知道对话框的建立，即稍后我以编程方式结束通话。 ..但是如何获得对话框的引用，并关闭它？

I could actually almost know when the dialog is brought up, i.e. a little later I programmatically end the call...but how can I get a reference to the dialog, and close it?

推荐答案

设备的按键注入关闭按钮如下所示：

Key press injection for device Close button looks like this:

KeyEvent inject = new KeyEvent(KeyEvent.KEY_DOWN, Characters.ESCAPE, 0); inject.post();

不要忘记设置设备版本的权限：选项=>高级选项= >应用程序=> [您的应用程序] =>编辑默认权限=>交互=>键击注入

Don't forget to set permissions for device release: Options => Advanced Options => Applications => [Your Application] =>Edit Default permissions =>Interactions =>key stroke Injection

可能有用： BlackBerry - 模拟一个KeyPress事件

代码示例：

class Scr extends MainScreen implements PhoneListener { public Scr() { Phone.addPhoneListener(this); } public boolean onClose() { Phone.removePhoneListener(this); return super.onClose(); } public void callDisconnected(int callId) { Timer timer = new Timer(); timer.schedule(new TimerTask(){public void run() { KeyEvent event = new KeyEvent(KeyEvent.KEY_DOWN, Characters.ESCAPE, KeyListener.STATUS_NOT_FROM_KEYPAD); event.post(); }}, 1000); } public void callAdded(int callId) { } public void callAnswered(int callId) { } public void callConferenceCallEstablished(int callId) { } public void callConnected(int callId) { } public void callDirectConnectConnected(int callId) { } public void callDirectConnectDisconnected(int callId) { } public void callEndedByUser(int callId) { } public void callFailed(int callId, int reason) { } public void callHeld(int callId) { } public void callIncoming(int callId) { } public void callInitiated(int callid) { } public void callRemoved(int callId) { } public void callResumed(int callId) { } public void callWaiting(int callid) { } public void conferenceCallDisconnected(int callId) { } }
