Android - imageview.setBackgroundResource issues -

-

i have image view have set 400dp(width) , 300dp(height). image view used in list view loading images url. during loading of images, show progess bar animation set this:

imageview.setbackgroundresource(r.drawable.progress);             final animationdrawable startanimation = (animationdrawable) imageview                     .getbackground();              startanimation.start();

once image finished loading , ll remove animation , set loaded image shown below:

imageview.setbackgroundresource(0);             imageview.setimagebitmap(bitmap);

but probelm is, animation taking specified width , height, ie 400dp , 300dp respectively, how can reduce size of animation drawable alone ?

my animation file: progress.xml

<?xml version="1.0" encoding="utf-8"?> <animation-list xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/anim_black"     android:oneshot="false" >      <item         android:drawable="@drawable/frame_1"         android:duration="100"/>     <item         android:drawable="@drawable/frame_2"         android:duration="100"/>     <item         android:drawable="@drawable/frame_3"         android:duration="100"/>     <item         android:drawable="@drawable/frame_4"         android:duration="100"/>     <item         android:drawable="@drawable/frame_5"         android:duration="100"/>     <item         android:drawable="@drawable/frame_6"         android:duration="100"/>     <item         android:drawable="@drawable/frame_7"         android:duration="100"/>     <item         android:drawable="@drawable/frame_8"         android:duration="100"/>     <item         android:drawable="@drawable/frame_9"         android:duration="100"/>     <item         android:drawable="@drawable/frame_10"         android:duration="100"/>     <item         android:drawable="@drawable/frame_11"         android:duration="100"/>     <item         android:drawable="@drawable/frame_12"         android:duration="100"/>  </animation-list>

frame 1, frame 2 ....frame 12 png files got splitting gif image.

you should use setimageresource animation in case. background image scaled fit whole image. need chage scaletype before starting animation , after image loaded well. 

imageview.setimageresource(r.drawable.progress); imageview.setscaletype(scaletype.center);  final animationdrawable startanimation = (animationdrawable) imageview.getdrawable(); startanimation.start();  // , once image loaded imageview.setimagebitmap(bitmap); imageview.setscaletype(scaletype.center_inside);

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
