Giving Ratings in Titanium
Posted By : Akshay Luthra | 06-May-2015
This blog explains how to make a Ratings view in a Titanium app to give review to a feature or a product. The view being made in this blog works both on iOS and Android.
In your "app.js", write the following code -
Titanium.UI.setBackgroundColor('#fff'); var win = Ti.UI.createWindow({ title : 'The Main Window', backgroundColor : '#fff' }); var view = Ti.UI.createView({ width : Ti.UI.FILL, height : Ti.UI.FILL, }); win.add(view); var tableView = Ti.UI.createTableView({ top : 40, showVerticalScrollIndicator : false, separatorColor : "transparent", separatorStyle : "NONE", height : Ti.UI.SIZE, scrollable : false, backgroundColor : "transparent", }); view.add(tableView); var scoreItems = ["Excellent", "Very Good", "Good", "Poor", "Very Poor"]; var data = []; /////making each review row///// for(var i = 0; i < scoreItems.length; i++) { var row = require('/reviewRow').createReviewRows({ rowdata : scoreItems[i], index : i, }); data.push(row); }; tableView.setData(data); tableView.addEventListener('click', function(e) { for(var j = 0; j < tableView.data[0].rows.length; j++) { var ee = tableView.data[0].rows[j]; if (j == e.index) { e.row.rowView.backgroundColor = "#D30A32"; for(var k = 0; k < e.row.rowIconData.length; k++) { e.row.rowIconData[k].image = "/blueStar.png"; }; } else { ee.rowView.backgroundColor = "#e3e4e4"; for(var l = 0; l < ee.rowIconData.length; l++) { ee.rowIconData[l].image = "/greyStarBorder.png"; }; } }; }); win.open();
Then make a "reviewRow,js" file in your Resources directory and write the following code in it -
exports.createReviewRows = function(params) { params = params || {}; var row = Ti.UI.createTableViewRow({ height : 44, backgroundColor : "transparent", className : "scoreRows", }); if (Ti.Platform.osname === 'android') { row.selectionStyle = Ti.UI.iPhone.TableViewCellSelectionStyle.NONE; } else { row.backgroundSelectedColor = "transparent"; } var rowView = Ti.UI.createView({ height : 34, top : 10, backgroundColor : "#e3e4e4", }); row.add(rowView); row.rowView = rowView; var rowLabel = Ti.UI.createLabel({ top : 4, left : 20, width : 150, text : params.rowdata, color : "#000", font : { fontFamily : 'Arial', fontSize : '17sp', fontWeight : "bold" }, }); rowView.add(rowLabel); var rowIconView = Ti.UI.createView({ right : 20, width : 120, layout : "horizontal", }); rowView.add(rowIconView); var starCount = 5 - params.index; var spaceCount = 5 - starCount; var rowIconData = []; for ( i = 0; i < spaceCount; i++) { spaceView = Ti.UI.createView({ width : 22, left : 2, }); rowIconView.add(spaceView); } for ( j = 0; j < starCount; j++) { rowIconData[j] = Ti.UI.createImageView({ top : 4, left : 2, height : 22, width : 22, image : "/greyStarBorder.png" }); } for (var i = 0; i < rowIconData.length; i++) { rowIconView.add(rowIconData[i]); }; row.rowIconData = rowIconData; return row; };
