關於android百度地圖離線地圖的使用

1.首先把離線地圖放在android工程下的assets裡面。

注意：建議離線地圖下載通過百度地圖APIDEMO去下載，因為到官網上下載的離線地圖文件格式不一樣，APIDEMO的格式是.dat,而官網上的格式是.dat_svc有可能加載不了地圖.

2.把離線地圖從assets下拷貝到sd卡下

public static void copy(Context context) {
try {
String filepath = Environment.getExternalStorageDirectory() + "/"
+ "BaiduMapSDK" + "/" + "vmp" + "/" + "h" + "/"
+ "xxxxx.dat";
String path = Environment.getExternalStorageDirectory() + "/"
+ "BaiduMapSDK" + "/" + "vmp" + "/" + "h" + "/";
File file = new File(path);
if (!file.exists()) {
file.mkdir();

}
if (!(new File(filepath)).exists()) {

new File(filepath).createNewFile();

InputStream is = context.getAssets().open(
"xxxx.dat");
FileOutputStream fos = new FileOutputStream(filepath);
byte[] buffer = new byte[8192];
int count = 0;
while ((count = is.read(buffer)) > 0) {
fos.write(buffer, 0, count);
}
fos.close();
is.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}

3.初始化離線地圖

private MKOfflineMap mOffline = null;
MapController mMapController;

mMapController = mMapView.getController();

mOffline = new MKOfflineMap();
mOffline.init(mMapController, new MKOfflineMapListener() {

@Override
public void onGetOfflineMapState(int type, int state) {
// TODO Auto-generated method stub

switch (type) {
case MKOfflineMap.TYPE_DOWNLOAD_UPDATE: {
}
break;
case MKOfflineMap.TYPE_NEW_OFFLINE:

break;

case MKOfflineMap.TYPE_VER_UPDATE:
break;
}

}
});
