这是我的MainActivity.java文件

public class MainActivity extends Activity {

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

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

这是我的清单

    </application>

</manifest>

这是我的activity_main.xml布局

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

我也在我的手机上运行它，而不是在模拟器上，我已经安装了谷歌播放服务，所以我不知道我在哪里犯了错误。提前谢谢。

Answer 1

t看起来你错过了从\extras\google\google_play_services\libproject\google-play-services_lib.

导入项目

将其添加为library到您当前的项目。

确保您已将SupportMapFragment用于11以下的API。

?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/map"
       android:name="com.google.android.gms.maps.SupportMapFragment"
       android:layout_width="wrap_content"
       android:layout_height="match_parent" />

当我在android中运行google maps v2时，我会强行关闭
