Question

我正在设计一个使用谷歌地图的应用程序。为了获取地图，我使用了以下代码：

    com.google.android.maps.MapView
    android:id="@+id/mapview" android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:clickable="true"
    android:apiKey="0V1xMgGND8LqWx0wO3Vkgs8Rj27aVCRp0biowfw" />

在xml文件中，但app force在运行后关闭。

如果我不使用这部分，那么剩下的代码就可以执行了。

使用google API 2.3作为目标
sdk version 1.6
使用Eclipse IDE for Java Developers 版本：Indigo Service Release 2 构建ID：20120216-1857
我放入了清单文件中的应用程序标记。
我甚至使用过这些权限

但我可以编译它而没有任何错误但无法运行它。我真的无法弄明白。这是logcat生成的日志。我可以从任何人那里得到一些帮助吗？

Answer 1

尝试不使用“wrap_content”作为高度，因为它似乎抛出和通胀异常。尝试获取dp值。或者，如果要将其调整到布局中的某个特定位置，请使用相对布局并使其相对于其他视图元素进行拉伸。只是不要单独使用“wrap_content”。

如果这不起作用，请回复我，我会尝试进一步协助。

Answer 2

应用程序标记下方的

添加<uses-library android:name="com.google.android.maps" /> xml指定android:layout_height="fill_parent"

如果可能，请尝试将项目构建目标Project->Properties->Android更改为Google API级别。

无法在xml文件中使用com.google.android.maps
