Custom MapView throwing NoSuchMethodException, but it's there!

I'm trying to implement a custom MapView. Inside my MapActivity (named mainmap) I have an inner class which extends MapView:

private class Lmapview extends MapView{

    public Lmapview(Context context, AttributeSet attrs) {
        super(context, attrs);
        gestures = new GestureDetector(mainmap.this, new GestureListener(this));
    }

    public boolean OnTouchEvent(MotionEvent event){
        return gestures.onTouchEvent(event);

    }
}

I have my main.xml formatted to find the inner class like so:

<?xml version="1.0" encoding="utf-8"?>
<view
    xmlns:android="http://schemas.android.com/apk/res/android"
    class="com.mondo.tbuddy.mainmap$Lmapview"
    android:id="@+id/mapview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:clickable="true"
    android:apiKey=*****
/>

Also, in Androidmanifest.xml, I have the appropriate <uses-library android:name="com.google.android.maps"/> entry.

When I try to run my app, I get (amongst other things) in logcat:

ERROR/AndroidRuntime(14999): Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class com.mondo.tbuddy.mainmap$Lmapview

This is caused by this entry I find in logcat:

ERROR/AndroidRuntime(14999): Caused by: java.lang.NoSuchMethodException: Lmapview(Context,AttributeSet)

If I understand correctly, my app is crashing because Android is saying it doesn't find the appropriate constructor for my custom MapView (the Lmapview class). As you can s开发者_JS百科ee above, however, it is defined and it matches the signature it is looking for.

Can anyone give me some insight?

Thanks.

You cannot instantiate an inner non-static class before you have a super class object. Because of this you have to make the inner class static, or move it to a separate class.
