Google Maps Android API V2问题

时间:2013-08-12 20:56:13

标签: android google-maps

我正在努力整理Google Maps Android API V2的实例。我找到了四个教程,描述了如何做到这一点(DJ-android,Vogella,官方文档的2个教程),但没有一个有效。我从其他开发人员那里找到了近十几个帖子,就像这个帖子一样,问题完全相同:“二进制XML文件行#x错误膨胀类”。在stackoverflow上,十几个帖子都没有一个接受的答案。我知道互联网上任何地方都没有这个API的实例。

我的项目内容粘贴在下面。我想我已经从所有这些不同的帖子中推荐了所有内容,但是和其他许多帖子一样,我得到了这个通胀运行时错误。

这个实际项目取自Vogella教程,该教程甚至无法编译。我在同一问题的其他帖子中应用了修复程序。

谁能告诉我如何使这项工作?有谁知道任何地方的工作示例? 谢谢,加里

我在工作区中有Google Play服务库项目。 。 。 I copied the library project into my workspace

我的主要布局XML文件。 。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.example.mapdemo.MainActivity"
    class="com.google.android.gms.maps.SupportMapFragment" />

</RelativeLayout> 

MainActivity.java文件。 。 。 (希望代码粘贴在这个论坛上工作)

package com.example.mapdemo;

答案 0 :(得分:2)

  

我知道互联网上任何地方都没有这个API的实例。

Here are 13 sample projects演示了如何使用Maps V2的各个方面。

我有理由相信,你开始使用的样品中有一些(如果不是全部的话)也可以使用。

  

谁能告诉我如何使这项工作?

你得到的是因为你的<meta-data>元素位置错误。它必须是<application>元素的子元素:

例如,

Lars Vogel's Maps V2 tutorial将它放在正确的位置。

答案 1 :(得分:1)

我遇到了和你一样的问题......当我将我的SDK更新到4.4 kitkat 时发生了 ..突然间一切都变得混乱了。我对Googlemapv2 apps非常熟悉,并且我之前开发了很多这些。但是今天我所有的googlemap应用都出现了这个错误

Binary XML file line #x Error inflating class Fragment 

每当我运行我编译的应用程序时......我怀疑此错误有4.4次更新。在此次更新之前,vogella和其他gmapv2教程没有任何问题。

答案 2 :(得分:0)

将这些元数据标签添加到清单文件

  <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="your api key" />
