android – 在集群管理器上刷新标记

当用户导航地图时,应用程序将获得新的位置供他查看.但是地图并没有使用新标记令人耳目一新. @H_607_5@ @H_607_5@收到带有地点的JSON后,此方法将它们放在地图上.

@H_607_5@

private void setMarkers(JSONObject responsE) {

    mClusteRMANager.clearItems();

    try {
        JSONArray venues = response.getJSONArray("venues");

        for (int i = 0; i < venues.length(); i++) {
            Venue venue = new Gson().fromJson(venues.getJSONObject(i).toString(),Venue.class);
            MarkerItem marker = new MarkerItem(venue.getLat(),venue.getLng(),venue,R.drawable.pin_quentE);
            mClusteRMANager.addItem(marker);
        }

    } catch (JSONException E) {
        e.printStackTrace();
    }
}

@H_607_5@第一个请求让他们好,但第二个请求什么也没做.

private void setMarkers(JSONObject responsE) {

    mClusteRMANager.clearItems();

    try {
        JSONArray venues = response.getJSONArray("venues");

        for (int i = 0; i < venues.length(); i++) {
            Venue venue = new Gson().fromJson(venues.getJSONObject(i).toString(),R.drawable.pin_quentE);
            mClusteRMANager.addItem(marker);
        }

        mClusteRMANager.cluster(); 

    } catch (JSONException E) {
        e.printStackTrace();
    }
}
