java - IndoorAtlas SDK 2.0 map 未加载

Question

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"

    <include
        android:id="@+id/toolbar"
        layout="@layout/toolbar" />

    <ImageView

Answer 1

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>

确保您拥有 IndoorAtlas 网站上的 API key 和 API key ，并将其包含在您的 Android list 文件中。从 github 存储库检查 android list ，链接如下:AndroidManifest.xml
