Question

如何在导航抽屉中使用片段地图？我试图使用但错误，所以我拥有三个按时间顺序排列的列表，其中包含显示地图，我创建了两个还是空的。当我在选择列表视图后打开第一个路线图时，两个都显示空白活动不是问题，当我想回到应用程序直接映射的情况时..

public class CreateFragment extends Fragment {
	
	
	public CreateFragment() {
		
	   
		
		
	}

	 
	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

		View rootView = inflater.inflate(R.layout.fragment_create, container, false);

		return rootView;
	}

}

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <fragment
        android:id="@+id/fragment1"
        android:name="com.google.android.gms.maps.MapFragment"
       
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" />

</RelativeLayout>

您可以尝试从此部分的导航抽屉中调用类似OpenMap（）的方法，该方法位于主活动中，其代码如下：

public void onSectionAttached(int number) {
        switch (number) {
            case 1:
                mTitle = getString(R.string.title_section1);
                OpenMap();
                break;




private void openMap() {
        double latitude = 32.715000;
        double longitude = -117.162500;
        String label = "Starting point";
        String uriBegin = "geo:" + latitude + "," + longitude;
        String query = latitude + "," + longitude + "(" + label + ")";
        String encodedQuery = Uri.encode(query);
        String uriString = uriBegin + "?q=" + encodedQuery + "&z=16";
        Uri uri = Uri.parse(uriString);
        Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
        startActivity(intent);
