我正在尝试将 GoogleMapview和 aListView合二为一activity。Mapview应取2/3上侧，列表下侧的 1/3（纵向）。
以这种方式假设它是肖像：http: //i.stack.imgur.com/IoGjr.png
MapView和,都ListView将收到相同的JSON信息，他们将得到onCreate()。我已经能够适应屏幕，并获取它获取位置的MapView数据。但我希望我得到的位置也显示在上面，有人可以告诉我，如何显示吗？2/3ListViewlistViewmaplocationmap
这是我的代码：
// 将请求设为私有的 url 静态String url = ""；//这里传递url
// JSON Node names
private static final String TAG_LOCATION = "location";
private static final String TAG_LOCATION1= "location";
private static final String TAG_LOCATION_ID = "LocationID";
private static final String TAG_NAME = "Name";
private static final String TAG_PHONE = "Phone";
private static final String TAG_FORMATTED_PHONE = "FormattedPhone";
private static final String TAG_ADDRESS = "Address";
private static final String TAG_CROSS_STREET = "CrossStreet";
private static final String TAG_LAT = "Lat";
private static final String TAG_LNG = "Lng";
private static final String TAG_DISTANCE= "Distance";
private static final String TAG_POSTAL_CODE = "PostalCode";
private static final String TAG_CITY = "City";
private static final String TAG_STATE = "State";
private static final String TAG_COUNTRY= "Country";
