我试图将我在教程中找到的一些代码转换为自己的用途。最初,当用户单击由我的应用程序生成的通知时,该代码启动了系统联系人列表。我尝试启动自己的Activity
而不是启动联系人列表,但它没有起作用。更具体地说,什么都没有发生。没有错误,我的Activity
也没有加载。单击后,通知窗口消失,并且原始的Activity
仍然可见。
这是我的代码:
public class MyBroadcastReceiver extends BroadcastReceiver {
private NotificationManager mNotificationManager;
private int SIMPLE_NOTFICATION_ID;
public void onReceive(Context context, Intent intent){
Bundle extras = intent.getExtras();
String deal = (String) extras.get("Deal");
String title = "Deal found at " + (String) extras.get("LocationName");
mNotificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notifyDetails = new Notification(R.drawable.icon, title,System.currentTimeMillis());
Class ourClass;
try {
ourClass = Class.forName("com.kjdv.gpsVegas.ViewTarget");
Intent startMyActivity = new Intent(context, ourClass);
PendingIntent myIntent = PendingIntent.getActivity(context, 0,startMyActivity, 0);
notifyDetails.setLatestEventInfo(context, title, deal, myIntent);
notifyDetails.flags |= Notification.FLAG_AUTO_CANCEL;
notifyDetails.flags |= Notification.DEFAULT_SOUND;
mNotificationManager.notify(SIMPLE_NOTFICATION_ID, notifyDetails);
}
catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
这是我在AndroidManifest.xml
文件中的条目...
<activity android:name=".ViewTarget" android:label="@string/app_name" >
<intent-filter>
<action android:name="com.kjdv.gpsVegas.ViewTarget" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
这是我希望启动的Activity
...
public class ViewTarget extends ListActivity {
public ListAdapter getListAdapter() {
return super.getListAdapter();
}
public ListView getListView() {
return super.getListView();
}
public void setListAdapter(ListAdapter adapter) {
super.setListAdapter(adapter);
}
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.locations);
Log.v("db", "Inside ViewTarget");
}
}
