泡泡图层PopupOverlay的使用

1、

private PopupOverlay   pop  = null;
/**
          * pop弹窗事件监控接口
          */
         PopupClickListener popListener = new PopupClickListener(){
            @Override
            public void onClickedPopup(int index) {
                //index - 当前点击的区域索引。
                if ( index == 0){
                    //更新item位置
                      pop.hidePop();
                      GeoPoint p = new GeoPoint(mCurItem.getPoint().getLatitudeE6()+5000,
                              mCurItem.getPoint().getLongitudeE6()+5000);
                      mCurItem.setGeoPoint(p);
                      mOverlay.updateItem(mCurItem);
                      mMapView.refresh();
                }
                else if(index == 2){
                    //更新图标
                    mCurItem.setMarker(getResources().getDrawable(R.drawable.nav_turn_via_1));
                    mOverlay.updateItem(mCurItem);
                    mMapView.refresh();
                }
            }
         };
         //PopupOverlay构造器
         pop = new PopupOverlay(mMapView,popListener);

2、显示

pop.showPopup(View view, GeoPoint point, int yOffset); //view：自定义 View //point：弹窗的位置(锚点在窗口的中下方向。水平方向：Center；垂直方向：Bottom) //yOffset：弹窗在y轴上的偏移量,取值范围yOffset>=0。单位：像素 

 xml

<?xml version="1.0" encoding="utf-8"?>

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="horizontal"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        >
        
    <TextView
        android:id="@+id/popleft"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/popup_side"
         android:gravity="center"
        android:textStyle="bold"
         android:textColor="#3814ed"
        android:text="交通顺畅"
        android:textSize="12sp" />

   
     <LinearLayout 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:id="@+id/popinfo"
        >
        
    <TextView
        android:id="@+id/textcache"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/popup_middle"
        android:gravity="center"
        android:textStyle="bold"
        android:textColor="@android:color/black"
        android:textSize="12sp" />
    
     <TextView
        android:id="@+id/popdown"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/popup_down"
        android:textColor="@android:color/black"
        android:textSize="12sp" />
    
    
    </LinearLayout>

     
    <TextView
        android:id="@+id/popright"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/popup_side"
        android:textColor="#3814ed"
        android:gravity="center"
        android:textStyle="bold"
        android:text="指点路况"
        android:textSize="12sp" />

</LinearLayout>

构造view

    private View viewCache;



        /**
         * 向地图添加自定义View.
         */
        viewCache = getLayoutInflater()
                .inflate(R.layout.custom_text_view, null);
        popupInfo = (View) viewCache.findViewById(R.id.popinfo);
        popupLeft = (View) viewCache.findViewById(R.id.popleft);
        popupRight = (View) viewCache.findViewById(R.id.popright);
        popupText = (TextView) viewCache.findViewById(R.id.textcache);

                popupText.setText("南湖大道");
                Bitmap[] bitMaps = { BMapUtil.getBitmapFromView(popupLeft),
                        BMapUtil.getBitmapFromView(popupInfo),
                        BMapUtil.getBitmapFromView(popupRight) };
                pop.showPopup(bitMaps, geoPoint, 32);

3、

        //收起pop弹窗
        if (pop != null){
            pop.hidePop();
        }

4、从view生成bitmap

public class BMapUtil {
        
    /**
     * 从view 得到图片
     * @param view
     * @return
     */
    public static Bitmap getBitmapFromView(View view) {
        view.destroyDrawingCache();
        view.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
                View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
        view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
        view.setDrawingCacheEnabled(true);
        Bitmap bitmap = view.getDrawingCache(true);
        return bitmap;
    }
}

Done！
