Question

我正在尝试在android.support.v4.app.Fragment中使用OSMdroid的离线模式。我的瓷砖由MOBAC使用＆＃34; OSMdroid Zip＆＃34;在地球的坐标0,0周围格式化（它只是海洋，但我只想要一些东西作为开头出现）。

我的zip文件位于/sdcard/osmdroid/MapquestOSM.zip，并包含文件夹MapQuest，其中包含自己在子文件夹中以数字作为名称的所有图块，从缩放11到缩放16.图块是png文件和有扩展＆＃34; .png＆＃34;。请注意，/ sdcard // osmdroid文件夹仅包含我的zip文件。

我的问题是我只看到一张空白地图，这是一个空的灰色网格。

public class ContactMapFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        super.onCreateView(inflater, container, savedInstanceState);
        return inflater.inflate(R.layout.map_fragment, container, false);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState){
        super.onActivityCreated(savedInstanceState);


        MapView map = (MapView) getActivity().findViewById(R.id.mapview);
        map.setBuiltInZoomControls(true);
        map.getController().setZoom(11);

        map.getController().setCenter(new GeoPoint(0,0));

        map.setClickable(true);
        map.setUseDataConnection(false);
        map.setMaxZoomLevel(16);
        map.setMinZoomLevel(11);

        map.setTileSource(new XYTileSource("MapQuest",
                ResourceProxy.string.offline_mode, 11, 16, 256, ".jpg", new String[] {
                "http://otile1.mqcdn.com/tiles/1.0.0/map/",
                "http://otile2.mqcdn.com/tiles/1.0.0/map/",
                "http://otile3.mqcdn.com/tiles/1.0.0/map/",
                "http://otile4.mqcdn.com/tiles/1.0.0/map/"})); 
    }
}

使用osmdroid-android-4.2和slf4j-api-1.7.10 权限是：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.READ_LOGS"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE"/>

所以我有两个问题：为什么没有显示？ XYTileSource中应该指向的URL是什么（我在教程中找到了这些URL）？

这是我最终使用的解决方案，它正在运行。如果我记得很清楚，你不必关心zip文件名，虽然我不确定它是真的。

pwd='/Users/pallavi/Documents/containers/platform241/etisalatwallet/api-server-tomcat-7/bin'
pwdlog='/Users/pallavi/Documents/containers/platform241/etisalatwallet/api-server-tomcat-7/logs'
pwd1='/Users/pallavi/Documents/containers/platform241/etisalatwallet/core-server-jboss-7.2/bin'
logpwd1='/Users/pallavi/Documents/containers/platform241/etisalatwallet/core-server-jboss-7.2/standalone/log'

osascript -e "tell application \"Terminal\"" \

-e "tell application \"System Events\" to keystroke \"t\" using {command down}" \
-e "do script \"cd $pwd\" in front window" \
-e "do script \"./startup.sh\" in front window" \
-e "tell application \"System Events\" to keystroke \"t\" using {command down}" \
-e "do script \"cd $pwdlog\" in front window" \
-e "do script \"tail -f catalina.out \" in front window" \
-e "tell application \"System Events\" to keystroke \"t\" using {command down}" \
-e "do script \"cd $pwd1\" in front window" \
-e "do script \"./standalone.sh\" in front window" \
-e "tell application \"System Events\" to keystroke \"t\" using {command down}" \
-e "do script \"cd $logpwd1\" in front window" \
-e "do script \"tail -f core.log \" in front window" \
-e "end tell"
> /dev/null

zip文件中包含以.png格式存储的磁贴。

希望它会有所帮助。
