Android : Setting width of picker does not work as expected when useSpinner property is set to true

Ti.UI.backgroundColor = 'black';

var win = Ti.UI.createWindow({

  exitOnClose: true,

  layout: 'vertical'

});

var picker = Ti.UI.createPicker({

  top:50,

  useSpinner:'true', //Comment this line to see width having effect. Works fine on iOS

  width:'75%', // Also, Ti.UI.FILL should fill up the screen. Does not work as expected on Android

});

var data = [];

data[0]=Ti.UI.createPickerRow({title:'Bananas',width:"80%"});

data[1]=Ti.UI.createPickerRow({title:'Strawberries',width:"80%"});

data[2]=Ti.UI.createPickerRow({title:'Mangos',width:"80%"});

data[3]=Ti.UI.createPickerRow({title:'Grapes',width:"80%"});

picker.add(data);

picker.selectionIndicator = true;

win.add(picker);

win.open();

// must be after picker has been displayed

picker.setSelectedRow(0, 2, false); // select Mangos
