Question

I\'m having android surfaceView and in that I\'m trying to add buttons to this. In the surfaceView canvas I draw something. And I have a thread class to keep drawing.

Answer 1

First, you must declare your view as a static type, to be able to be inflated it even when no instance of the holding class is available:

public static class MySurfaceView extends SurfaceView 
    implements SurfaceHolder.Callback

The line

<com.androidsurfaceview.test.MySurfaceView

in your layout xml suggests, that the MySurfaceView class is inside the com.androidsurfaceview.test package, and tries to inflate it from there, which is wrong.

In your layout you should follow the package.class$innerclass form of declaration.

BUT since the "$" is illegal character, you cannot write

<com.androidsurfaceview.test$MySurfaceView

so you must specify your view in the layout xml as follows:

<view class="com.androidsurfaceview.test$MySurfaceView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>

This way it will work.
