title: How I can increase or decrease the size of an ImageView?
body: <p>I would like to know how to enlarge an image that is already in the <code>ImageView</code>.</p>
  
  <p>I have this:</p>
  
  <pre><code>m_imageView.setImageBitmap(imagen); 
  int newHeight = getWindowManager().getDefaultDisplay().getHeight() / 2;
  int orgWidth = m_imageView.getDrawable().getIntrinsicWidth();
  int orgHeight = m_imageView.getDrawable().getIntrinsicWidth();
  int newWidth = (int) Math.floor((orgWidth * newHeight) / orgHeight);
  //Use RelativeLayout.LayoutParams if your parent is a RelativeLayout
  LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                  newWidth, newHeight);
  m_imageView.setLayoutParams(params);
  //m_imageView.setScaleType(ImageView.ScaleType.FIT_START);
  </code></pre>
  
  <p>But it does nothing, the image remains the same.</p>
  
  <p>Thank you for your help.</p>
