Binding Multiple Spinner Controls with sqllite

hi guys,

hope you are doing well in android. Today my code is about binding multiple dependent spinner controls. These spinner controls are binded with the sql lite database which i would be dealing in my next post. The following code would give you an idea about how to bind multiple spinner controls.

Step1 Bind the spinners
Step2 based on the selection of search create an array
Step3 check the selection made by the user and remove the dependents in case the user selects the default value from the spinner control.
Step4 bind the data and pass it on to the result page.

Hope you guys get some idea about binding the spinner control. Here is the code

GPS System Using Google Map and PhoneGap Android

Hi Folks!,

Today i am going to tell you about the GPS system which actually makes a path on the map when the device is moved from one location to another.The application works like this

Step1 The geolocation of the device is detected by the geolocation.js provided by phonegap.

Step2. The timer checks the location after every 3 seconds.

Step3. The map is updated.

Below is the complete code for it.

Send SMS Using Android Phonegap

Hi Folks!,

Hope you have enjoyed the previous posts and got the working knowledge of the android. Today we are going to do some different stuff using the PhoneGap Open Source Through which we can do lot many things on cross platform mobile phones. Please read the help file with phonegap and then read the following code. The code here would send the sms using the phonegap plugin.

Step 1. Install Phonegap from http://phonegap.com/.

Step 2. Install The plugins for phonegap available on github.

Step 3. Look for SmsPlugin folder and copy the smsplugin.java into your "src" folder in eclipse.

Step 4. Add the following code in your html file.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="width=320; user-scalable=no" />
<title>Send SMS</title>
   
    <link href="css/style.css" rel="stylesheet" type="text/css" />

    <script src="jquery-1.6.min.js" type="text/javascript" />

    <script src="cordova-1.6.1.js" type="text/javascript" />

    <script src="jquery.mobile-1.0b3.min.js" type="text/javascript" />

    <script src="smsplugin.js" type="text/javascript" />

<script type="text/javascript">             
        function onDeviceReady () {
            $('#send').bind('click', function () {
               
                window.plugins.sms.send($('#phone').val(), $("#txtMessage").val(),
                    function () {
                       alert('Your Message has been sent successfully.');   
                       $("#txtMessage").val("");
                    },
                    function (e) {
                        alert('Sorry There Was An Error :' + e);
                    }
               
                );
              
            });                           
        }
</head>
<body>
        <dl>
            <dt style="width: 80px; margin-left: 18px">Message</dt>
            <dd>
                <textarea rows="3" cols="23" id="txtMessage" name="txtMessage"></textarea></dd>
        </dl>
        </div>
        <div class="info" style="text-align: center">
            <img id="send" src="images\button.jpg" />
        </div>
</body>

Step 5: Modify plugins.xml and add the following line

<plugin name="SmsPlugin" value="ritesh.tandon.sendsms.SmsPlugin" />

here instead of ritesh.tandon.sendsms write your package name and class name.

Thats it folks! , you are ready for the show.

Thnx
Ritessh
