I use the following code to retrieve image from the phone or SDCard and I use that image in to my ListField. It gives the output but it takes very Long time to produce the screen. How to solve this problem ?? Can any one help me?? Thanks in advance!!!
String text = fileholder.getFileName();
try{
String path="file:///"+fileholder.getPath()+text;
//path=”file:///SDCard/BlackBerry/pictures/image.bmp”
InputStream inputStream = null;
//Get File Connection
FileConnection fileConnection = (FileConnection) Connector.open(path);
inputStream = fileConnection.openInputStream();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int j = 0;
while((j=inputStream.read()) != -1) {
baos.write(j);
}
byte data[] = baos.toByteArray();
inputStream.close();
fileConnection.close();
//Encode and Resize image
EncodedImage eImage = EncodedImage.createEncodedImage(data,0,data.length);
int scaleFactorX = Fixed32.div(Fixed32.toFP(eImage.getWidth()), Fixed32.toFP(180));
int scaleFactorY = Fixed32.div(Fixed32.toFP(eImage.getHeight()), Fixed32.toFP(180));
eImage=eImage.scaleImage32(scaleFactorX, scaleFactorY);
Bitmap bitmapImage = eImage.getBitmap();
graphics.drawBitmap(0, y+1, 40, 40,bitmapImage, 0, 0);
graphics.drawText(text, 25, y,0,width);
}
catch(Exception e){}
