This is a great script for grabbing an image from the web for a Blackberry App. Now I would like to know how to center the returned image. I have tried everything.
This portion of code seems to return the image:
byte[] dataArray = data.getBytes();
bitmap = EncodedImage.createEncodedImage(dataArray, 0,
dataArray.length);
setImage(bitmap);
This displays the image:
getimage = new WebBitmapField("http://"); add (getimage);
Where can I put FIELD_HCENTER to center this thing. Please show sample code. Thanks!!
If you insist on using this WebBitmapField, then you'll need to add a new constructor so that style bits can be passed to the BitmapField:
public class WebBitmapField extends BitmapField implements WebDataCallback
{
...
public WebBitmapField(String url, long style)
{
super(style);
try
{
Util.getWebData(url, this);
}
catch (Exception e) {}
}
public WebBitmapField(String url)
{
this(url, 0L);
}
...
}
If you place your WebBitmapField in a custom manager and set the position of the field then u can possibly achieve the center location like:
class CustomManager extends Manager
{
CustomManager()
{
super(Manager.USE_ALL_WIDTH);
}
sublayout(int width , int height)
{
Field field = getField(0);
layoutChild(field , Display.getWidth(), Display.getHeight());
setPositionChild(field, (Display.getWidth()- field.getWidth())/2,
Display.getHeight());
setExtent( Display.getWidth(), Display.getHeight());
}
}
In MainScreen use it as:
CustomManager obj = new CustomManager();
getimage = new WebBitmapField("http://");
obj.add(getimage );
add(obj);
