Question

我正试图建立一个能够指导一个人到目的地的原型。

place is a wide building with several floors.
i can obtain/retrieve the maps (still images). e.g. current:1F destination:5F; so I can get the still images of 1st,2nd...5th floors (5 image files).

<>Scenario:

start the application
input the current location (or may automatically set using current location) & destination
click the search route button to search the maps to use (still images) & mark the current location & destination
update the current location upon moving/going to destination

<<>Problem>:

I just need to display 1 image file (each floor) at a time then move to other floor by using scroll bar. But.. don t know how to display it.
I can get the current location coordinate via WiFi but don t know how to put it into still image to mark the current location.

For sure there is already look a like sample application available. Could you share the concepts/ideas or would you include the code snippets. Big Help with my thesis.

赞赏对正确方向的任何指导。

你有两种可能性,即制作你自己的地图集,像反对在谷歌阿皮上播下你地图。可通过Location dev Guide 查询。

通过你本人这样做如果你理解动物群和pan体的基本制图和转变,观点就会比较容易。 (如果你算好的话,那不会遇到学习困难。) 采用带<条码>的图像学:尺度Type=“matrix”高于动议接着,接手把电线打成安放和循环矩阵。

To associate the indicator to the image make two pixels into anchor points that coorespond to a real life lat/long. Usually its (0,0) and (width,height) of a rectangular image. Make your life easier and make sure the images are to scale. Then using a second ImageView (for the indicator) draw it on top and move it to the correct place on the screen and make sure the background in this View is transparent as well as the background of your indicator or you ll have a rectangular block "halo".

保证检查地点管理者给出的每个地点是否准确。

onCurrentPosition(Location current){
    double hypotenuse = upperLeft.distanceTo(current);
    double bearing = upperLeft.bearingTo(current);
    double currentDistanceX = Math.cos(bearing) * hypotenuse;
    //                     "percentage to mark the position"
    double currentPixelX = (currentDistanceX / upperLeft.distanceTo(lowerRight) * Math.cos(upperLeft.bearingTo(lowerRight))) * mapWidth;

    moveIndicatorX(currentPixelX);
}
