我希望在进入/退出地理围栏区域时直接将活动带到前台。
我有5个地理围栏区域,并希望在我进入地理围栏区域A(在纬度/长度中指定)时将ActivityA带到前台,当我在地理围栏时是活动B是B等等。 (这是一个非消费者应用程序,所以我不介意直接从服务调用活动到前台。)
我在Android上阅读了关于Geofencing的this documentation。当他们收到地理围栏区域的不同ID时,如何调用不同的活动?
待定意图:
public class MainActivity extends FragmentActivity {
...
private PendingIntent getTransitionPendingIntent() {
Intent intent = new Intent(this,
ReceiveTransitionsIntentService.class);
return PendingIntent.getService(
this,
0,
intent,
PendingIntent.FLAG_UPDATE_CURRENT);
}
...
}
Handler Intent:
protected void onHandleIntent(Intent intent) {
if (LocationClient.hasError(intent)) {
int errorCode = LocationClient.getErrorCode(intent);
Log.e("ReceiveTransitionsIntentService",
"Location Services error: " +
Integer.toString(errorCode));
} else {
// Get the type of transition (entry or exit)
int transitionType =
LocationClient.getGeofenceTransition(intent);
// Test that a valid transition was reported
if (
(transitionType == Geofence.GEOFENCE_TRANSITION_ENTER)
||
(transitionType == Geofence.GEOFENCE_TRANSITION_EXIT)
) {
List <Geofence> triggerList =
getTriggeringGeofences(intent);
String[] triggerIds = new String[geofenceList.size()];
for (int i = 0; i < triggerIds.length; i++) {
// Store the Id of each geofence
triggerIds[i] = triggerList.get(i).getRequestId();
}
}
} else {
Log.e("ReceiveTransitionsIntentService",
"Geofence transition error: " +
Integer.toString()transitionType));
}
}

documentation表示你不应该这样做:
从位置服务发送的Intent可以在您的应用中触发各种操作,但您不应该让它启动活动或片段,因为组件只应在响应用户操作时变得可见。在许多情况下,IntentService是处理意图的好方法。
