致命异常：主要，膨胀类片段时出错，android.view.InflateException

Question

我正在尝试制作地图应用程序。使用按钮链接到 MapActivity 类，但当我按下按钮时应用程序立即崩溃。请告知，如果需要更多信息来解决错误，请随时向我提出要求。

MapActivity.java

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_map); //<-- logcat points at this line

    }

根据您的完整堆栈跟踪，您没有在清单中输入 API 密钥。将以下内容放入清单中，<application> 标记下。

<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value=" your key here" />

按照此处的指南设置 API 密钥
