我正在使用以下代码(尤其是pushMessage
方法)向用户显示一些通知:
public final class MyApplicationMessageFolder
{
public static final long MyFolderId = 0x1256789012F10123L;
private ApplicationMessageFolder folder_;
private ApplicationIndicator indicator_;
private MyReadableListImpl collection_;
public void pushMessage(String subject, String message)
{
try
{
if (collection_ == null)
{
collection_ = new MyReadableListImpl();
}
if (indicator_ == null)
{
registerFolderAndIndicator();
}
ApplicationMessage am = new MyApplicationMessage(message, subject);
collection_.addMessage(am);
folder_.fireElementAdded(am);
// Update indicator
int size = collection_.size();
indicator_.setValue(size);
indicator_.setVisible(size > 0);
}
catch (Exception e)
{
System.out.println(e.getMessage());
}
}
private void registerFolderAndIndicator()
{
// registration application folder and indicator
ApplicationMessageFolderRegistry amfr =
ApplicationMessageFolderRegistry.getInstance();
folder_ = amfr.getApplicationFolder(MyFolderId );
if (folder_ == null)
{
folder_ =
amfr.registerFolder(MyFolderId , "My Folder", collection_, true);
ApplicationIcon icon =
new ApplicationIcon(image_ = EncodedImage.getEncodedImageResource("my_icon.png"), true);
int status = ApplicationMessage.Status.INCOMING | ApplicationMessage.Status.UNOPENED;
amfr.registerMessageIcon(0, status, icon);
folder_.setSearchProperties(new ApplicationMessageSearchProperties(true));
folder_.addListener(
new ApplicationMessageFolderListener() {
public void actionPerformed(int action, ApplicationMessage[] messages,
ApplicationMessageFolder folder) {
if (action == ApplicationMessageFolderListener.MESSAGE_DELETED) {
for (int i = 0; i < messages.length; i++)
collection_.removeMessage(messages[i]);
indicator_.setValue(collection_.size());
indicator_.setVisible(collection_.size() > 0);
}
}
},
ApplicationMessageFolderListener.MESSAGE_DELETED |
ApplicationMessageFolderListener.MESSAGE_MARKED_OPENED |
ApplicationMessageFolderListener.MESSAGE_MARKED_UNOPENED,
ApplicationDescriptor.currentApplicationDescriptor());
ApplicationMenuItem[] menu = new ApplicationMenuItem[] {
new ApplicationMenuItem(0) {
public String toString() {
return "Go to application";
}
public Object run(Object context) {
return null;
}
}
};
amfr.registerMessageMenuItems(0, status, menu,
ApplicationDescriptor.currentApplicationDescriptor());
amfr.setBulkMarkOperationsSupport(0, status, true, false);
ApplicationIndicatorRegistry air = ApplicationIndicatorRegistry.getInstance();
air.register(new ApplicationIcon(EncodedImage
.getEncodedImageResource("bar_icon_25.png")),
false, false);
indicator_ = air.getApplicationIndicator();
}
}
class MyApplicationMessage implements ApplicationMessage
{
private String message_;
private String subject_;
private long timestamp_;
public MyApplicationMessage(String message, String subject) {
message_ = message;
subject_ = subject;
timestamp_ = new Date().getTime();
}
public String getContact() {
return "HelloWorld";
}
public Object getCookie(int cookieId) {
return null;
}
public Object getPreviewPicture() {
return image_;
}
public String getPreviewText() {
return message_;
}
public int getStatus() {
return ApplicationMessage.Status.UNOPENED;
}
public String getSubject() {
return subject_;
}
public long getTimestamp() {
return timestamp_;
}
public int getType() {
return 0x01;
}
}
private class MyReadableListImpl implements ReadableList {
private final Vector messages;
MyReadableListImpl() {
messages = new Vector();
}
public Object getAt(final int index) {
return messages.elementAt(index);
}
public int getAt(final int index, final int count,
final Object[] elements, final int destIndex) {
return 0;
}
public int getIndex(final Object element) {
return messages.indexOf(element);
}
public int size() {
return messages.size();
}
void addMessage(final ApplicationMessage message) {
messages.addElement(message);
}
void removeMessage(final ApplicationMessage message) {
messages.removeElement(message);
}
}
}
我可以在我的消息文件夹中看到我的消息,但我仍然无法在通知栏中看到它们
任何人都可以解释为什么我看到空的通知栏吗?

答案 0 :(得分:1)
要查看通知下拉列表中的消息,需要使用:
ApplicationFolderIntegrationConfig config = new
ApplicationFolderIntegrationConfig(true, true,
ApplicationDescriptor.currentApplicationDescriptor());
folder_ = amfr.registerFolder(MyFolderId , "My Folder", collection_, config);
代替:
folder_ = amfr.registerFolder(MyFolderId , "My Folder", collection_, true);
