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，但应用程序强制在运行后关闭。

如果我不使用这部分，那么其余代码都可以正常执行。

  1. 使用 google APIs 2.3 作为目标
  2. sdk 版本 1.6
  3. 使用 Eclipse IDE for Java Developers 版本：Indigo Service Release 2 Build id：20120216-1857
  4. 我已将应用程序标记放入清单文件中。
  5. 我什至使用了权限

但是，我可以编译它而没有任何错误，但无法运行它。我实在想不通。这是 logcat 生成的日志。我可以从任何人那里得到一些帮助...？

尝试不要将“wrap_content”用于高度，因为它似乎会抛出和膨胀异常。尝试获取 dp 值。或者，如果您想让它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，我会尽力提供进一步的帮助。

在应用程序标签下方添加<uses-library android:name="com.google.android.maps" />在 xml 中指定android:layout_height="fill_parent"

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