title: Android set Tag, findViewWithTag
body: <p>I'm trying to find an ImageView by tag. I assign a tag for the ImageView, but when I try to findViewWithTag, it returns null. I read that I should add to the view the childer with addChilder, but the view doesnt have this function. Can someone explaim to me how I can do this?</p>
  
  <pre><code>ImageView principal = (ImageView) findViewById(R.id.imagen_home_0);
      principal.setTag("principal");
  </code></pre>
  
  <p>in other class(AsyncTask) that i pass the context</p>
  
  <pre><code>        View noMiembros = new View(context);
  
          ImageView er = (ImageView) noMiembros.findViewWithTag("principal");
          er.setImageBitmap(result);
  </code></pre>
