ArcGis for android 加载tpk离线文件

1.安装 arcgis android sdk （必须安装过 android sdk及 adt 环境喲）

创建一个本地缓存arcgis android项目

如下代码

[java] view
plaincopy

package com.esri.arcgis.android.samples.localtiledlayer;



import android.app.Activity;

import android.os.Bundle;

import android.os.Environment;



import com.esri.android.map.MapView;

import com.esri.android.map.ags.ArcGISLocalTiledLayer;



/**

* This sample illustrates the use of ArcGISLocatlTiledLayer where the data is stored locally on the device, therefore

* this layer can function even when the device does not have any network connectivity. The data for this layer must be

* in an ArcGIS Compact Cache format (Tile Packages or .tpk's are not currently supported).

* The typical compact cache structure is as follows:

* <CacheName><br>

* Layers<br>

* _allLayers<br>

* conf.cdi,conf.xml<br>

* The path used in the constructor of the ArcGISLocalTiledLayer must point to the Layers folder e.g. <br>

* ArcGISLocalTiledLayer local = new ArcGISLocalTiledLayer("file:///mnt/sdcard/<CacheName>/Layers");

*

* A sample data set has been created and is available via ArcGIS Online:

* http://www.arcgis.com/home/item.html?id=d2d263a280164a039ef0a02e26ee0501

* 1) In order to use the data, download it from the url above

* 2) Copy the data to your sdcard

* 3) Set the path to the data by replacing <CacheName> with file:///mnt/sdcard/Parcels/v101/Parcel Map

* on line60 below.

*

* You can also use your own data if it is in an ArcGIS Compact Cache format, for more information on

* this data format see this link:

* http://blogs.esri.com/Dev/blogs/arcgisserver/archive/2010/05/27/Introducing-the-compact-cache-storage-format.aspx

*

public class LocalTiledLayer extends Activity {



MapView map = null;

ArcGISLocalTiledLayer local;



/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

map = (MapView) findViewById(R.id.map);



//the data is stored on the SDCARD

//the data is created as a tiled cache

// local = new ArcGISLocalTiledLayer("file:///mnt/sdcard/ArcGIS/Basemap/Layers");

// local = new ArcGISLocalTiledLayer(Environment.getExternalStorageDirectory()

// + "/YX1.tpk"); // 不行

local = new ArcGISLocalTiledLayer("file:///storage/sdcard0/YX1.tpk"); // ok

map.addLayer(local);

}

}
