Blackberry: Custom Popup Screen[Forgot Password Example]

Here I am providing one example that shows how we customize our Popup Screen. We can use this like a popup Screen or Dialog Screen. 

Below link is the Example for the Custom Popup Screen and I am showing an example of Forgot Password. 

https://www.dropbox.com/s/9sy9t7y87jdh0r0/CustomPopupExample.zip

In this you will get again two custom classes. Like, PictureBackgroundButtonField and CustomTextField where we can use images directly to the buttons and text fields. 

It will look like the below image:

Lets try this one. 

Feel free to ask questions.

Blackberry: Post Data Using JSON Object

We can post the data by the JSON format. 

For this first,

1. We have to take all the keys and values in One Hash table or Array of Hash tables(Vector)

2. Convert it into JSON object.

3. Send to server.

}

and the method for Utility.escapeHTML(url) is:

public static String escapeHTML(String s)
{
               StringBuffer sb = new StringBuffer();
               int n = s.length();
               for (int i = 0; i < n; i++) {
                     char c = s.charAt(i);
                      switch (c) {
                                           case ‘ ‘: sb.append(“%20″); break;
                                         default: sb.append(c); break;
                     }
             }
            return sb.toString();
}

Blackberry - Rotate an image in any degree

This BitmapRotation works from Blackberry Version 5.0 on-wards.

Do the following steps:

1. Download the zip file from this link: BitmapRotate at down side.

2. Extract and take the ImageManipulator.java from that add to your project;

3. and use this code from this link: RotatingBitmap on Blackberry;

or

take MY code from the below LINK for rotate an image in BB:

BitmapRotate.zip

Otherwise take this code:

1. Download the zip file from this link: BitmapRotate at down side.

2. Extract and take the ImageManipulator.java from that add to your project;

and then in our code:

================== StartUp.java===================



public class StartUp extends UiApplication
{
public static void main(String[] args)
{
StartUp app = new StartUp();
app.enterEventDispatcher();
}

public StartUp()

pushScreen(screen);
}

public static void showAlertMessage(final String message)
{
UiApplication.getUiApplication().invokeLater(new Runnable()
{
public void run()
{
Dialog.alert(message);
}
});
}
}

================ RotateScreen.java=============

public class RotateScreen extends MainScreen
{
private BitmapField bitmapField = new BitmapField();
private Bitmap bitmap = Bitmap.getBitmapResource("simple.png");
private ImageManipulator imageManip = new ImageManipulator(bitmap);
private int angle=0;

}
}

}
}
}.start();

} catch (Exception e) {

QRCode Scanning for Blackberry Version 5.0

For this Take the sample code from this following link:

QRCode 5.0

In the above sample application we have QRCode implementation is in "com.alishaik.qrcode.startup";

and if you want to do the this in separately you must add the packages which are provided in the below link:

ZXIng For 5.0  and you and do by your self;

The above ZXIng For 5.0  link nothing but I downloaded this in the below link and separate the packages

http://code.google.com/p/zxing/downloads/list

For Version>5.0 no need to take all these; From 6.0 on wards we have the packages;

I think it helps you alot;

For 6.0 see this below links:

XMLFileParsing Using DOM In Blackberry

The sample XML file is:

sample.xml:

<ROOT>
<ROW Name="Product Name~B" CheckBox="" Type="PerformanceNormal" Count="1" ChildCount="1" Show="Y" Refine="B">   
   <COL Page="1" Image="" ProductID="3">Sainsbury's aromatherapy citrus mint</COL>
   <COL Page="1" Image="" ProductID="4">TestPerf</COL>      
   <COL Page="2" Image="" ProductID="25">Acb</COL>
</ROW>
<ROW Name="Region~H" CheckBox="" Type="PerformanceNormal" Count="2" ChildCount="1" Show="Y" Refine="H">   
   <COL Page="1" Image="" ProductID="3">Western Europe</COL>  
   <COL Page="1" Image="" ProductID="5">Western Europe</COL>
   <COL Page="1" Image="" ProductID="24">Central and Eastern Europe</COL>   
</ROW>

</ROOT>
--------------------------------
and parse this xml file like:
