Hello i have facebook image that i have to compress and put it in my imageview. I used below code to resize my image and compress it so that i can show it in my imageview but it gives file not found exception error
i do not find any way to compress file/image that located on server. you can take bitmap from URL and the you suppose to re size.
For Getting Bitmap From URL.
URL url = new URL("http://....");
Bitmap image = BitmapFactory.decodeStream(url.openConnection().getInputStream());
for resize you can use below code
public Bitmap getResizedBitmap(Bitmap bm, int newHeight, int newWidth) {
int width = bm.getWidth();
int height = bm.getHeight();
float scaleWidth = ((float) newWidth) / width;
float scaleHeight = ((float) newHeight) / height;
// CREATE A MATRIX FOR THE MANIPULATION
Matrix matrix = new Matrix();
// RESIZE THE BIT MAP
matrix.postScale(scaleWidth, scaleHeight);
// "RECREATE" THE NEW BITMAP
Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false);
return resizedBitmap;
}
How to use :- place this code:-
private void showImage(final String URL) {
new Thread(new Runnable() {
@Override
public void run() {
URL url = new URL(URL);
Bitmap bm = BitmapFactory.decodeStream(url.openConnection()
.getInputStream());
int width = bm.getWidth();
int height = bm.getHeight();
float scaleWidth = ((float) YOUR_WIDTH) / width;
float scaleHeight = ((float) YOUR_HEIGHT) / height;
// CREATE A MATRIX FOR THE MANIPULATION
Matrix matrix = new Matrix();
// RESIZE THE BIT MAP
matrix.postScale(scaleWidth, scaleHeight);
// "RECREATE" THE NEW BITMAP
final Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width,
height, matrix, false);
runOnUiThread(new Runnable() {
@Override
public void run() {
your_imageView.setImageBitmap(resizedBitmap);
}
})
}
}).start();
}
thanks.
