我正在尝试在我的项目中使用 IndoorAtlas。我创建了 Activity this例如，但是当我启动 Activity 时，我什么也没看到， map 没有加载到 ImageView 中，并且 LogCat 仅显示几行。请帮忙。
我的 LogCat 带有“IndoorAtlas”过滤器:
D/IndoorAtlasActivity: onCreate/ requestLocationUpdates() called
D/IndoorAtlasActivity: onResume/ requestLocationUpdates() called
D/IACore: IndoorAtlas Android SDK
SDK : 2.0.2-beta-9999
Android: 4.2.1-17
Date : Sat, 20 Feb 2016 22:14:41 GMT
我的XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include

<ImageView

最佳答案
您不需要 ImageView 来加载和显示平面图。您需要一个名为“BlueDotView”的类，您可以从此链接找到它:BlueDotView class 。如果您正确地浏览ImageViewActivity类(从创建 Activity 的位置)，您将看到没有需要使用的此类 ImageView 。 ImageViewActivity 类具有以下内容:
private BlueDotView mImageView;。
为了正确加载平面图，请执行以下步骤。
1. 使用 ImageViewActivity 正确交叉检查您的 Activity 。
2. 您必须将 BlueDotView 类作为单独的类。
3. 在您的activity_indooratlas XML 文件中，您应该有如下内容，这些内容来自 SDK 2.0 的 github 存储库，而不是 XML 文件中的内容:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<com.indooratlas.android.sdk.examples.imageview.BlueDotView
android:id="@+id/imageView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
