我试图通过通知和事件来运行一个活动onCreate
我想“重定向”。 这个在上添加信息的思想Intent
类。 一个重要的特征是,产生所述通知的类是通过服务来执行。 我检索从上下文getApplicationContext
由类提供的方法android.app.Application
。 每当我调用方法getExtras()
将返回null
。 我究竟做错了什么?
public class OXAppUpdateHandler {
private void addNotification(Context context, int iconID,
CharSequence tickerText, CharSequence title, CharSequence content) {
CharSequence notificationTicket = tickerText;
CharSequence notificationTitle = title;
CharSequence notificationContent = content;
long when = System.currentTimeMillis();
Intent intent = new Intent(context, MainActivity_.class);
intent.setFlags(
Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.putExtra(OPEN_UPDATE_ACTIVITY_KEY, 1);
PendingIntent pendingIntent =
PendingIntent.getActivity(context, 0, intent, 0);
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(
Context.NOTIFICATION_SERVICE);
Notification notification =
new Notification(iconID, notificationTicket, when);
notification.setLatestEventInfo(context, notificationTitle,
notificationContent, pendingIntent);
notificationManager.notify(NOTIFICATION_ID, notification);
}
public static boolean isUpdateStart(Intent intent) {
Bundle bundle = intent.getExtras();
boolean result = bundle != null &&
bundle.containsKey(OPEN_UPDATE_ACTIVITY_KEY);
if (result) {
bundle.remove(OPEN_UPDATE_ACTIVITY_KEY);
}
return result;
}
}
@EActivity(R.layout.activity_main)
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (OXAppUpdateHandler.isUpdateStart(getIntent())) {
startActivity(new Intent(this, UpdateActivity_.class));
}
}
}
