Code Examples

Multi-Column Picker

Create a two-column, platform-specific style, picker and automatically select a row in each column.

var win = Ti.UI.createWindow({
  backgroundColor: 'white',
  exitOnClose: true,
  fullscreen: false,
  title: 'Use picker to make selection'
});
 
var fruit = [ 'Bananas', 'Grapes', 'Blueberries', 'Strawberries' ];
var color = [ 'blue', 'red', 'yellow', 'white' ];
 
var column1 = Ti.UI.createPickerColumn();
 
for(var i=0, ilen=fruit.length; i&lt;ilen; i++){
  var row = Ti.UI.createPickerRow({
    title: fruit[i]
  });
  column1.addRow(row);
}
 
var column2 = Ti.UI.createPickerColumn();
 
for(var i=0, ilen=color.length; i&lt;ilen; i++){
  var row = Ti.UI.createPickerRow({
    title: color[i]
  });
  column2.addRow(row);
}
 
var picker = Ti.UI.createPicker({
  columns: [column1, column2],
  selectionIndicator: true,
  useSpinner: true, // required in order to use multi-column pickers with Android
  top:50
});
 
function pickerDefaults(obj){
  // on iOS, must be after picker has been rendered
  picker.setSelectedRow(0, 2, false);
  picker.setSelectedRow(1, 3, false);
}
 
win.add(picker);
 
var isAndroid = Ti.Platform.osname === 'android';
 
if(isAndroid){
  pickerDefaults(picker);
}
 
win.open();
 
if(!isAndroid){
  setTimeout(function(){
    pickerDefaults(picker);
  }, 1500);
}
