高德地图自定义点聚合样式Android

写了Android高德地图的点聚合功能

不废话:直接上代码

  private ClusterOverlay mClusterOverlay;    private int clusterRadius = 100;    private void dianjuhePipeout() {        List items = new ArrayList();        if (null!=pipeoutList && !"".equals(pipeoutList) && pipeoutList.size()>0) {            for (int i = 0; i < pipeoutList.size(); i++) {                LatLng latLng = new LatLng(pipeoutList.get(i).getLat(), pipeoutList.get(i).getLng(),false);                RegionItem regionItem = new RegionItem(latLng,                        "test" );                items.add(regionItem);            }            mClusterOverlay = new ClusterOverlay(mAMap, items,                    dp2px(getActivity().getApplicationContext(), clusterRadius),                    getActivity());            mClusterOverlay.setClusterRenderer(this);            mClusterOverlay.setOnClusterClickListener(this);        }    }

里面有一句

mClusterOverlay.setClusterRenderer(this);

这个在类里实现了

public class FragmentMain extends BaseFragment implements SensorEventListener, View.OnClickListener,ClusterRender ,ClusterClickListe

ClusterRender接口，重写了getDrawAble方法

然后看下面的代码 被注释掉的是demo原来的样式，被注释掉的下面的一行是我自己设置的样式,可以分别设置当聚合点=1时,<5,<10和>10时的样式。

  private Map mBackDrawAbles = new HashMap();    @Override    public Drawable getDrawAble(int clusterNum) {        int radius = dp2px(getActivity().getApplicationContext(), 80);        if (clusterNum == 1) {            Drawable bitmapDrawable = mBackDrawAbles.get(1);            if (bitmapDrawable == null) {                bitmapDrawable =                       getActivity().getApplicationContext().getResources().getDrawable(//                                R.drawable.icon_openmap_mark);                                R.mipmap.ic_map_paishui);                mBackDrawAbles.put(1, bitmapDrawable);            }            return bitmapDrawable;        } else if (clusterNum < 5) {        //聚合数量小于5时//            Drawable bitmapDrawable = mBackDrawAbles.get(2);            Drawable bitmapDrawable = getActivity().getResources().getDrawable(R.drawable.yello_56x56);            if (bitmapDrawable == null) {                bitmapDrawable = new BitmapDrawable(null, drawCircle(radius,                        Color.argb(159, 210, 154, 6)));                mBackDrawAbles.put(2, bitmapDrawable);            }            return bitmapDrawable;        } else if (clusterNum < 10) {       //聚合数量小于10时//            Drawable bitmapDrawable = mBackDrawAbles.get(3);            Drawable bitmapDrawable = getActivity().getResources().getDrawable(R.drawable.red_66x65);            if (bitmapDrawable == null) {                bitmapDrawable = new BitmapDrawable(null, drawCircle(radius,                        Color.argb(199, 217, 114, 0)));                mBackDrawAbles.put(3, bitmapDrawable);            }            return bitmapDrawable;        } else {        //聚合数量大于10时//            Drawable bitmapDrawable = mBackDrawAbles.get(4);            Drawable bitmapDrawable = getActivity().getResources().getDrawable(R.drawable.pink_78x77);            if (bitmapDrawable == null) {                bitmapDrawable = new BitmapDrawable(null, drawCircle(radius,                        Color.argb(235, 215, 66, 2)));                mBackDrawAbles.put(4, bitmapDrawable);            }            return bitmapDrawable;        }    }

当然你也可以按顺序把drawable对象添加到mBackDrawAbles集合中,也是一样的效果,这里我就不多做说明了。

差点忘了还有一个方法差点忘记贴了

  /**     * 根据手机的分辨率从 dp 的单位 转成为 px(像素)     */    public int dp2px(Context context, float dpValue) {        final float scale = context.getResources().getDisplayMetrics().density;        return (int) (dpValue * scale + 0.5f);    }
