Question

我们希望在地图上显示建筑物中特定物品（计算机，监视器等）的位置。地图应该浏览地图的不同图层。

//编辑：
我们不想为每种可能性重新绘制每一个svg 我不知道怎么告诉svg它应该自己改变特定房间的颜色。
我想知道如何从建筑物的概述链接到特定的房间，以引导用户到位置作为一个例子，我知道我正在寻找一张3014房间的桌子，这个房间号码我可以得到这张桌子位于该楼层＃14房间的第三层楼的信息。

我们svg的一个例子

以及我们如何在应用中打开svg

    public class JavaScriptInterface {
        Context mContext;

JavaScriptInterface(Context c) {
            mContext = c;
        }

        @JavascriptInterface
        public void showToast(final String room) {
            MapActivity.this.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    mWebView.loadUrl("file:///android_asset/" + room + ".svg");


                    history.add(mWebView.getUrl());
                }
            });

            Toast.makeText(mContext, room, Toast.LENGTH_SHORT).show();
        }

    }
