【问题描述】:
我已经为单点创建了标注功能,它真的很容易工作而没有任何中断,但是当我有多个点时,标注功能仅适用于最后一点,其他点不起作用我不知道为什么我在谷歌搜索了很多次但我没有得到任何结果,下面的代码适用于单点:
mMapView.setOnSingleTapListener(new OnSingleTapListener() {
private static final long serialVersionUID = 1L;
@Override
public void onSingleTap(float x, float y) {
callout.hide();
// Handles the tapping on Graphic
int[] graphicIDs = graphicsLayer.getGraphicIDs(x, y, 25);
if (graphicIDs != null && graphicIDs.length > 0) {
Graphic gr = graphicsLayer.getGraphic(graphicIDs[0]);
Point location = (Point) gr.getGeometry();
SpatialReference sp = SpatialReference
.create(SpatialReference.WKID_WGS84);
Point aux = (Point) GeometryEngine.project(location,
mMapView.getSpatialReference(), sp);
try {
DecimalFormat df = new DecimalFormat("00.000000");
String latitude = df.format(aux.getX());
String longtitude = df.format(aux.getY());
Double finallat = (Double) df.parse(latitude);
Double finallon = (Double) df.parse(longtitude);
Log.e("LLLLL", latitude + ": " + longtitude);
updateContent(
(String) gr.getAttributeValue("Rating"),
(String) gr.getAttributeValue("Title"),
(String) gr.getAttributeValue("Category"),
finallat, finallon);
callout.setOffset(0, -15);
callout.show(location, content);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (java.text.ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
});
上面的 onsingleTaplistener 代码,updateContent 函数代码:
public void updateContent(String rating, String title, String cate,
Double finallat, Double finallon) {
if (content == null)
return;
Log.e("Double", finallat + ":" + finallon);
Cursor cur = database.showInfo(finallat, finallon);
if (cur.moveToFirst()) {
name = cur.getString(0);
cata = cur.getString(1);
vic = cur.getString(2);
}
Log.e("Name", name + ":" + cata + ":" + vic);
TextView txt = (TextView) content.findViewById(TITLE_ID);
txt.setText(name);
TextView txt1 = (TextView) content.findViewById(REVIEW_ID);
txt1.setText(cata);
TextView txt2 = (TextView) content.findViewById(CATE_ID);
txt2.setText(vic);
}
createCongent 函数的代码:
public View createContent() {
// create linear layout for the entire view
View view = LayoutInflater.from(SingleLocation.this).inflate(
R.layout.sqmi, null);
TextView titleView = (TextView) view.findViewById(R.id.county_name);
titleView.setId(TITLE_ID);
titleView.setTextColor(Color.BLACK);
TextView titleView1 = (TextView) view.findViewById(R.id.vic);
titleView1.setId(REVIEW_ID);
titleView1.setTextColor(Color.BLACK);
TextView titleView2 = (TextView) view.findViewById(R.id.cate);
titleView2.setId(CATE_ID);
titleView2.setTextColor(Color.BLACK);
view.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Message.message(getApplicationContext(),"you clicked");
}
});
return view;
}
这对我有用,但是当我导入相同的代码时,当我有多个点时它不起作用,请我需要您的评论,感谢您的帮助...
