You have to create it by your own, a first look it would be a Window with 0.7 opacity, a view that contains the the black and two white views (preferably horizontal ) each of them contains a label and another view or button for your custom confirmation, you can also use border width and border color for the light gray details. i have created something similar: http://postimg.org/image/6ygh7wi6p/
Here is the code:
var mainWindow = Titanium.UI.createWindow({
modal: true,
navBarHidden : true,
backgroundImage:"/global/bg-opacity.png_preview_70x50.png"
});
var alertView = Ti.UI.createView({
width: 300,
height: 500,
borderColor : Alloy.CFG.colors.SILVER,
borderWidth : 1,
backgroundColor:"black",
});
var titleLabel = Ti.UI.createLabel({
top: 10,
height : 40,
left:10,
color : "white",
font : Alloy.CFG.fonts.DEFAULT_22_BOLD,
text: "BACK-UP CARE MOBILE"
});
var testWrapper = Ti.UI.createScrollView({
top:55,
widht:Ti.UI.FILL,
height:385,
borderColor : "#181818",
borderWidth : 1
});
alertView.add(testWrapper);
var textLabel = Ti.UI.createLabel({
top : 10,
bottom: 10,
left : 20,
right : 20,
textAlign: "left",
height : Ti.UI.SIZE,
font : Alloy.CFG.fonts.DEFAULT_17,
color : "white",
text : App.localize("FIRST_RUN_MESSAGE")
});
testWrapper.add(textLabel);
var buttonsWrapper = Ti.UI.createView({
top:440,
height:60,
widht:Ti.UI.FILL,
backgroundColor:"#848684"
});
alertView.add(buttonsWrapper);
var continueBtn = Ti.UI.createButton({
title: 'Continue',
top: 5,
width: 140,
height: 50,
left:155
});
buttonsWrapper.add(continueBtn);
var createProfileBtn = Ti.UI.createButton({
title: 'Create Profile',
top: 5,
width: 140,
height: 50,
left:5
});
buttonsWrapper.add(createProfileBtn);
mainWindow.addEventListener("android:back", function(){
});
Hope it helps.
