回答1:

You need to load the google maps javascript api.

you can do this by adding the code in your index.html file.

<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=true"></script>

Two things

1) The panel which contains map should be card layout.

2) Without setting center mapOptions, map not showing.

Give Lat & Lng value as you need.

var mapapnel = Ext.create('Ext.Panel', {
          id: 'mapapnel',
          layout:'card',
          items: [{
              xtype: 'toolbar',
              ui:'light',
              docked: 'top',
              title: 'Find location',
              items: [{
                  text: 'Back',
                  ui: 'back',
                  handler: function() {
                     Ext.getCmp('homepnl').setActiveItem(1);
                  }
              }
            ]},
            {
             xtype:'map',
             useCurrentLocation:true,
             mapOptions: {
              zoom: 12,
              zoomControl : true,
              center: new google.maps.LatLng(Lat, Lng),
              disableDefaultUI: true
           }]
});
