如何放置一个ViewFlipper内多MapViews V1 [英] How to place Multiple MapViews v1 inside a ViewFlipper

问题描述

目标 - 我想表现出不同的地图活动根据数据库，数据显示，使用视图的鳍状肢（或类似的东西）的幻灯片演示

Objective- I want to show slide shows of different Map Activities which show data according to database, using view flipper(or something similar).

问题：

1. 查看翻转不能被添加到这不是一个MapActivity如果鳍含有MapView的一个活动。

1. View Flipper can't be added to an Activity that is not a MapActivity if flipper contains a mapview.

查看挡板不会允许添加多个mapviews为一体MapActivity只能有一个地图视图。

View Flipper does not allows adding multiple mapviews as one MapActivity can have only one map view.

我希望实现什么

1. 要显示多个MapActivities这显示标记，路线等基于数据库的数据的幻灯片。


2. 要刷新这些MapActivities也有新的数据定期获取并更新数据库。

推荐答案

我没有找到标准的解决方案，以作为视图的鳍状肢不能使用我的问题。我做了以下实现MapView类幻灯片 。它是一种比砍一个妥善的解决办法更多，但我别无选择。

I did not find standard solution to my problem as view flipper could not be used.I did the following to implement mapview slide show. Its more of a hack than a proper solution but I had no choice.

1. 在while循环，我不停地重新呈现在异步map任务相同的地图视图。

2.After 1地图加载我叫了Thread.Sleep（10000）。

2.After 1st map is loaded I called thread.sleep(10000).

3.我清除了所有的路线和标记的MapView。

3.I cleared the mapview of all routes and markers.

4。我重新呈现第二地图视图。

4.I re rendered the 2nd map view.

在即指否极泰来步骤都不断重复。

5.And the steps were repeated continuously.

@Override
    protected Void doInBackground(Void... params) {
        final Drawable marker_inBetween;

        marker_inBetween = getResources().getDrawable(R.drawable.blue_pin);
        marker_inBetween.setBounds(0, 0,
                marker_inBetween.getIntrinsicWidth(),
                marker_inBetween.getIntrinsicHeight());

        helper = new DbHelper(getApplicationContext());
                    // show slide show
            while (true) {
        ArrayList<String> IdList =showAllPeopleOnMap();


                util.haveASleep(slideShowInterval);

                showEachPersonRouteOnMap(IdList);
                resetVariables();//resets lists,routes,removes markers etc
            }
        }
        return null;
    }
