main.xml中

</RelativeLayout>

MainActivity.java

public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);}

}

我真的很想知道我做错了什么，我才能真正学会自己解决这些问题。

Answer 1

在Manifest中，我们只需要以下内容即可显示谷歌地图：

<manifest ….>
      <uses-permission android:name="android.permission.INTERNET" />
      <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
      <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
      <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

      <application ….>
          <activity … />
          <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
          <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your api key" />
      </application>

      <uses-feature android:glEsVersion="0x00020000" android:required="true" />

</manifest>

将您的片段代码更改为：

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

清理项目并运行。

Answer 2

清单文件中的错字：

<meta-data android:name ="com.google.android.gms.verson"
    android:value ="@integer/google_play_services_version"/>

将verson更改为version。

Android Google Maps V2给了我IllegalStateException
