我的 activity_map.xml 文件：

【问题讨论】：

您是否将 api_key 添加到清单中？
您能否编辑问题以使其更具可读性，并为您的问题提供更多背景信息
请在第 41 行附近提供MapActivity.java 的代码。
@Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_map);获取位置权限（）； }
是的，我在清单中添加了 api_key。

标签： android google-maps android-studio

【解决方案1】：

请在您的布局 xml 中使用它：

<fragment
    class="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

使用

class="com.google.android.gms.maps.MapFragment"

而不是

android:name=com.google.android.gms.maps.SupportMapFragment"
