title: What image size should I ask from UI developer?
body: <p>I have an <code>ImageView</code> with these attributes:</p>
  
  <pre><code>   android:layout_width="match_parent"
     android:layout_height="160dp"
  </code></pre>
  
  <p>UI developer asks me for the size of Image that I want in px. What size should I ask? Should I ask different size for different devices?</p>
  
  <p><strong>Note</strong></p>
  
  <p>I don't have an <code>ImageView</code> with specific height and width. My <code>ImageView</code> width is <code>match_parent</code> not a specific width.</p>
  
  <p><strong>All the answers say that I should use a converter, How can I convert <code>match_parent</code> to <code>px</code>?</strong></p>
  
  <p>According to answers, I should ask about six images, shouldn't I?</p>
