Simple use of ArcGIS for Android collout

1. Define the appearance of callout, which can be defined in an XML file.

<? XML version = "1.0" encoding = "UTF-8"?> <Resources> <calloutviewstyle titletextcolor = "#000000" <! -Title color/> titletextsize = 10; <! -Title font size/> titletextstyle = 0; <! -Title Font/> backgroundcolor = "# ffffff" <! -Background color/> backgroundalpha = "255" <! -Transparency 0 (transparent) to 255 (opaque)/> framecolor = "#000000" <! -Border color/> flat = "true" <! -Whether it will be in 3D effect/> cornercurve = "0" <! -Degree of rounded corner/> anchor = "5"/> <! -Position of the anchor (0-8)/> </resources>

2. Define the content to be displayed in callout, which can be defined in a layout.

<? Xmlversion ="1.0"Encoding ="UTF-8"?>

<Linearlayoutxmlns: Android =Http://schemas.android.com/apk/res/android"

Android: layout_width ="Wrap_content"

Android: layout_height ="Wrap_content"

Android: gravity ="Center">

<Imageview

Android: src ="@ Drawable/ic_launcher"

Android: layout_width ="Wrap_content"

Android: layout_height ="Wrap_content"

/>

<TextviewAndroid: text ="This is callout"

Android: layout_width ="Wrap_content"

Android: layout_height ="Wrap_content"/>

</Linearlayout>

 

3. Display callout. The following code displays callout when you click the screen.

Public
Class Callouttestactivity ExtendsActivityImplementsOnsingletaplistener {

Mapviewmmapview;

PrivateCalloutcallout;

 

/** Called when the activity is first created .*/

@ Override

Public
VoidOncreate (bundlesavedinstancestate ){

Super. Oncreate (savedinstancestate );

Setcontentview (R. layout.Main);

 

Mmapview = (mapview) findviewbyid (R. Id.Mapview);

Arcgistiledmapservicelayerarm =NewArcgistiledmapservicelayer ("http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer ");

Mmapview. addlayer (ARM );

Mmapview. setonsingletaplistener (This);

Callout = mmapview. getcallout (); // obtain the callout of the mapview. One mapview can have only one callout.

}

 

Public
VoidOnsingletap (FloatArg0,FloatArg1 ){

Pointp = mmapview. tomappoint (NewPoint (arg0, arg1 ));

Callout.Setstyle(R. xml.Colloutxml); // Set the display style (XML defined in step 1)

Callout. setcontent (view.Inflate(This, R. layout.Colloutlay,Null); // Use the layout defined in step 1 as the display content of callout.

Callout. setcoordinates (p); // set the displayed position to the clicked position.

Callout. Show (); // display callout

}

}
