Size and content(String) of Callout

Question

Hello, I am trying to show Callout containing String value in it. The problem is that Callout showing up is very small. Also, I cannot see any string values (please see the attached jpg)... I have checked the following point with debugging. 1."myPopupInfo" and "popupContent" have expecting string values. Also, I have checked some other posts in this forum. They are very helpful for me to understand basic ideas of Callout. But I still could not figure out my own problem... I may be either missing very basic but necessary components or doing stupid basic errors in my codes... I would be very grateful if anybody helped me out. I have been stuck at this point since last night... Thank you so much in advance, Gakumin Here is my java code. (Sorry, it is little long. But I wanted to include all blocks related to Callout.)protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.map_view); //Set a default tap action as pop-up Map_view.setOnSingleTapListener(new OnSingleTapListener() { private static final long serialVersionUID = 1L; public void onSingleTap(float x_v, float y_v) { Point point = Map_view.toMapPoint(x_v, y_v); // Tolerance: 20 pixel Envelope env_v = new Envelope(point,20*Map_view.getResolution(), 20*Map_view.getResolution()); new setDefaultTapActions_popup(env_v, dmsl_v.getSpatialReference(), point).execute(".../MapServer/0"); } }); } //Query dynamic map service layer by QueryTask(Modified from "PopupInWebmapForViewing.java") private class setDefaultTapActions_popup extends AsyncTask { private Envelope env_v; private SpatialReference sr; private Point point; public setDefaultTapActions_popup(Envelope env_v, SpatialReference sr, Point point) { super(); this.env_v = env_v; this.sr = sr; this.point = point; } @Override protected View doInBackground(String... params) { //Set query parameters Query query = new Query(); query.setInSpatialReference(sr); query.setOutSpatialReference(sr); query.setGeometry(env_v); //For now, max number of returned features is 10. query.setMaxFeatures(10); query.setOutFields(new String[] { "*" }); QueryTask queryTask = new QueryTask(".../MapServer/0"); //Execute query task try { FeatureSet fs_view = queryTask.execute(query); //Get an array of graphics of the query result FeatureSet Graphic[] resultGraphic = fs_view.getGraphics(); View popupview = createPopupView(resultGraphic[0]); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } // TODO Auto-generated method stub return null; } @Override protected void onPostExecute(View popupView) { // TODO Auto-generated method stub super.onPostExecute(popupView); Callout callout = Map_view.getCallout(); callout.setStyle(R.xml.callout_style); callout.getStyle().setMaxHeight(150); callout.getStyle().setMaxWidth(150); callout.setContent(popupView); callout.show(point); } private View createPopupView(Graphic graphic) { //Employ "createReportView" of "MyWater" sample of ESRI //LinearLayout ret = new LinearLayout(context); //ret.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, // LayoutParams.WRAP_CONTENT)); Object attribute; attribute = graphic.getAttributeValue("Type_Store"); String Type_Store = null; if (attribute != null){ Type_Store = (String)attribute; } attribute = graphic.getAttributeValue("Name_Store"); String Name_Store = null; if (attribute != null){ Name_Store = (String)attribute; } attribute = graphic.getAttributeValue("Open_Close"); String Open_Close = null; if (attribute != null){ Open_Close = (String)attribute; } attribute = graphic.getAttributeValue("Service"); String Service = null; if (attribute != null){ Service = (String)attribute; } attribute = graphic.getAttributeValue("AmountSup"); Integer AmountSup = 0; if (attribute != null){ AmountSup = (Integer)attribute; } StringBuilder myPopupInfo = new StringBuilder(); myPopupInfo.append("Type of Store: " + Type_Store); myPopupInfo.append(" Name of Store: " + Name_Store); myPopupInfo.append(" Open or Close?: " + Open_Close); myPopupInfo.append(" Service: " + Service); myPopupInfo.append(" Amount of Supply: " + AmountSup); // TextView popupContent = new TextView(context); View popupView = getLayoutInflater().inflate( R.layout.callout_view2, null); TextView popupContent = (TextView) popupView .findViewById(R.id.callout_textview2); popupContent.setText(myPopupInfo.toString()); popupContent.setTextColor(Color.WHITE); popupContent.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 9); popupContent.setPadding(1, 0, 1, 0); return popupView; // ret.addView(popupContent); // TODO Auto-generated method stub // return ret; } } Here is my "callout_view2" layout xml Here is my "callout_style" xml Callout.JPG

Hi all,

I have found why I could not make this work.
This was not issue of size of Callout. It was my simple coding error... 
I have not returned anything after query in doInBackground. 
Here is the updated code.

I am still beginner level programmer... Sorry about this.

   //Execute query task
   try {
    FeatureSet fs_view = queryTask.execute(query);
    //Get an array of graphics of the query result FeatureSet
    Graphic[] resultGraphic = fs_view.getGraphics();
    View popupview = createPopupView(resultGraphic[0]);
                          //Added this one
    return popupview;
   } catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
