Implementing extended/custom View throws NoSuchMethod for constructor
<p>I have a customized TextView which implements the three View constructors (nb, this is my first stab at an android app):</p>

<pre><code>public class DynamicGeometryTextView extends TextView {

    public DynamicGeometryTextView (Context con) { super(con); }

    public DynamicGeometryTextView (Context con, AttributeSet attrs) {
        super(con, attrs);
    }

    public DynamicGeometryTextView (Context con, AttributeSet attrs, int style) {
        super(con, attrs, style); 
    }
</code></pre>

<p>This is a non-static inner class, since it needs to access instance data from the outer class.  It appears in an .xml layout:</p>

<pre><code>&lt;view class="cogdis.chalkboard.DisplayText$DynamicGeometryTextView"
    android:id="@+id/chalkboard"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" /&gt; 
</code></pre>

<p>Everything compiles and installs fine, but at runtime:</p>

<p>To my eye, this implies it can't find the (Context, AttributeSet) version of the constructor...but it exists.  I've looked at a few other SO posts, like <a href="http://stackoverflow.com/questions/2884501/android-custom-view-constructor">Android Custom View Constructor</a>, this all point to the same conclusion (to my eye) and read the API Guide on Custom Components repeatedly, but I've been stumped with this for more than an hour.</p>

<p>Anyone have any ideas? Is there a way to debug this further?</p>

<p><strong>FOR POSTERITY</strong>, ie., anyone new to this like me, non-static inner classes are a no-go if your custom View is referenced in an XML layout, but if you create it programmatically, it can work, eg:</p>

<pre><code>    LayoutInflater lif = getLayoutInflater();
    ViewGroup layout = (ViewGroup)lif.inflate(R.layout.board, null);

    tv = new DynamicGeometryTextView(this);

    layout.addView((View)tv);
</code></pre>

<p>In this case, you only need to match the constructors you actually use. Layout parameters (WRAP_CONTENT, etc) can be set in the constructor via <code>setLayoutParams()</code> which is inherited from View.</p>
