DateTime

First, you have to DateTime Layout class:

      import com.infairy.cocina.SDK.Layout.Layout;
      import com.infairy.cocina.SDK.Layout.LayoutDateTime;
      

Then, get Layout service

        Layout layout=(Layout)Tools.getService(context, Layout.class.getName(), "(FUNCTION=LAYOUT)");
      

Next, create layout tag and get LayoutID for other layout object used purpose:

            LayoutTag ltag=new LayoutTag();

            ltag.backgroundImage="img/background.png";
            ltag.bundleID=BundleID;
            ltag.LayoutHeight=450;
            ltag.LayoutWidth=800;
            ltag.title="My App";
            /*
             * Create layout tag and get layout id for other layout object use
             */
            LayoutID=layout.createUI(this, ltag);
      

Nex, create DateTime layout object:

          LayoutDateTime ldt=new LayoutDateTime();
          ldt.LayoutID=LayoutID[0];

          //DateTime format, refer to com.ifnairy.cocina.SDK.device.DevicePool#LAYOUT_TYPE_TIME_FORMAT_xxx
          ldt.format=device.LAYOUT_TYPE_TIME_FORMAT_YEAR_MONTH_DAY;
          ldt.width=149;
          ldt.height=30;
          ldt.left=537;
          ldt.top=14;
          ldt.fontColor="#4b718a";
          ldt.fontSize=30;

          /*
           * Create DateTime object
           */
          layout.createUI(this, ldt);

          
      

The DateTime layout can be clicked by users, you just need to do defined the key value:

          ldt.key=device.DEVICE_OPERATION_USER_DEFINED_0;
      

"DEVICE_OPERATION_USER_DEFINED_0" is defined by com.infairy.cocina.SDK.device.DevicePool#DEVICE_OPERATION_xxx
then defined the Operation object( refer to Operation):

        public class myFirstBundle implements BundleActivator, Runnable{
            ...
           
           /*
            * Bundle ID
            */
           String BundleID="";
           
           /*
            * Layout ID
            */
           String LayoutID="";
           
           Thread me;

           /*
            * Layout object 
            */
           Layout layout;
           
          /*
           * entry point
           */
          public void start(BundleContext context) throws Exception {
              ...
              /*
               * get layout service
               */
              layout=(Layout)Tools.getService(context, Layout.class.getName(), "(FUNCTION=LAYOUT)");

              .....

              /*
               * define operation for layout key mapping
               */
              Vector Operation=new Vector();
              OperationDNA oobj=new OperationDNA();
              
              //when user click the image layout object, this operation object will trigger to run the Funtoin:Go()
              oobj.KEY=device.DEVICE_OPERATION_USER_DEFINED_0;   
              oobj.Function="Go";
              Operation.addElement(oobj);
              
              dict.put(InfairyInterface.DeviceOperation, Operation);

              ...
              
              BundleID=device.addDevice(this, dict);
            

You have also implemnt Go() function to catch up the action.

              public void Go(){
                ....
              }
            

The DateTime layout object properties show as below:

          
            /**
             * layout id of bundle
             */
            public String LayoutID="";
            /**
             * layout axis of top, default is 0
             */
            public int top=0;
            /**
             * layout axis of left, default is 0
             */
            public int left=0;
            /**
             * layout width in pixel, default is 10
             */
            public int width=10;
            /**
             * layout height in pixel, default is 10
             */
            public int height=10;
            /**
             * font size, default is 10
             */
            public int fontSize=10;

             */
            public String format="hh:mm";
            /**
             * font color
