Question

ImageButton avatarButton = (ImageButton) findViewById(R.id.ImageButton_Avatar);
avatarButton.setImageResource(R.drawable.avatar);
strAvatarFilename =  "Image.jpg"; 
final Uri imageUriToSaveCameraImageTo = Uri.fromFile(new File(Environment.getExternalStorageDirectory()+"/Folder/"+strAvatarFilename));
avatarButton.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        Intent pictureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        pictureIntent.putExtra( MediaStore.EXTRA_OUTPUT, imageUriToSaveCameraImageTo );
        startActivityForResult(Intent.createChooser(pictureIntent, strAvatarPrompt), TAKE_AVATAR_CAMERA_REQUEST);
        Editor editor = Preferences.edit();
        editor.putString(PREFERENCES_AVATAR, imageUriToSaveCameraImageTo.getPath());
        editor.commit();
    }
});

I have this code. It takes a photo and then stores it in two locations, the default location on the SDcard and the /folder/ file i want the photo to be stored in also. Once taken i refresh the screen using this…

ImageButton avatarButton = (ImageButton) findViewById(R.id.ImageButton_Avatar);
String strAvatarUri = Preferences.getString(PREFERENCES_AVATAR, "");
Uri imageUri = Uri.parse(strAvatarUri);
avatarButton.setImageURI(null);
avatarButton.setImageURI(imageUri);

This refreshes the image button so the user can see the image they have taken. However, this is appears very big and fills the screen. Is there any way i can compress or downsize the image so the user can see it at a reasonable size? thanks

You can mess with the ImageButton’s scaleType properties (to fitXY for example, or cropCenter), and by setting a fixed size to LayoutPreferences (height and width) you’ll be all set.
