Question

我在谷歌地图上工作并使用Fragment而不是Fragmentactivity，但没有工作。我的代码如下。

map.xml

**<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/LinearLayout1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    >
 <com.google.android.gms.maps.MapView
            android:id="@+id/mapview"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />
    </LinearLayout>**

Map.java

public class Maps extends Fragment {

    MapView m;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // inflat and return the layout
        View v = inflater.inflate(R.layout.maps, container, false);
        m = (MapView) v.findViewById(R.id.mapview);
        m.onCreate(savedInstanceState);

        return v;
    }

    @Override
    public void onResume() {
        super.onResume();
        m.onResume();
    }

    @Override
    public void onPause() {
        super.onPause();
        m.onPause();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        m.onDestroy();
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        m.onLowMemory();
    }
}

            android:theme="@style/AppTheme" >
        </activity>
    </application>

</manifest>

此代码但不成功。像这样的Gettin错误..

java.lang.RuntimeException: API key not found.  Check that <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

Answer 1

您必须在Manifest.xml中再添加一个元数据

        meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="your key"

Answer 2

您已使用不推荐使用的mapv1，请使用mapv2

如何在Android中显示地图？
