Adding custom component in xml error
<p>I'm trying to create simple custom component that draws Bitmap. It works fine when I'm adding it programatically.</p>

<pre><code>RelativeLayout layout = (RelativeLayout) findViewById(R.id.linlay); Bitmap mBitmap = BitmapFactory.decodeResource(getResources(),
               R.drawable.girl);

AdView ad = new AdView(this,mBitmap);

layout.addView(ad);
</code></pre>

<p>But when I try to add it through xml file I get error:</p>

<pre><code>&lt;test.com.ad.AdView
   android:id="@+id/ad"
   android:layout_width="fill_parent" 
   android:layout_height="wrap_content" 
   &gt;&lt;/test.com.ad.AdView&gt;
</code></pre>

<p>My onMeasure looks like that:</p>

<pre><code>@Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // TODO Auto-generated method stub
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        setMeasuredDimension(resolveSize(bitmap.getWidth(), widthMeasureSpec),
                resolveSize(bitmap.getHeight(), heightMeasureSpec));

    }
</code></pre>

<p>What is wrong here ?</p>
