How I can increase or decrease the size of an ImageView?
<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>
