Spying on Android events without modifying source code

I wonder if you can achieve the same thing by inserting a debug class that replaces the original parent. That is, change the code to go from<p><pre><code> View &lt;-- MyView </code></pre> to<p><pre><code> View &lt;-- DebugView &lt;-- MyView </code></pre> You might even be able to do this without decompiling the code.
