我正在尝试通过 shop_name 从我的数据库中获取纬度和经度，以便我可以使用它从我的位置获取方向。
这是我的地图活动：
public class SearchLocation extends MapActivity {
private MapView mapView;
private LocationManager locManager;
private LocationListener locListener;

这是我调用地图活动的代码：

// TODO Auto-generated method stub
final Entity_BikeShopRepair toko = adapterShop.getItem(position);
CharSequence[] items = { "View on Map", "Call Shop" };

Tab_Shop_Repair_ListView_Activity.this);
builder.setTitle(toko.getShop_Name());
builder.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
switch (item) {
case 0:
String nama = toko.getShop_Name().toString();
Intent intentmap = new Intent(
Tab_Shop_Repair_ListView_Activity.this,
SearchLocation.class);
startActivity(intentmap);
break;
case 1:
String number = "tel:" + toko.getPhone_Number().toString();
Intent intent = new Intent(Intent.ACTION_CALL, Uri
.parse(number));
startActivity(intent);
break;
case 2:
break;
}
}
});
AlertDialog alert = builder.create();
alert.show();
}
