Swapping views disables the soft keyboard?

Hi,

sorry if this isn't the best board to ask this, but I thought it would be since my objective is to display the soft keyboard over a GLSurfaceView. Why does swapping a view (in my case, two GLSurfaceViews) prevent me from openning the software keyboard? Here is an example snippet (coded for Froyo):

    public void onSurfaceChanged(GL10 arg0, int arg1, int arg2) {
    }
 
    @Override
    public void onSurfaceCreated(GL10 gl, EGLConfig config) {
        gl.glClearColor(0.f, 0.f, 1.f, 1.f);
    }
}

When it opens initially, it works correctly. After pressing the back button (sorry for the non-intuitiveness of using the back key), it stops working. What am I missing to make it work? Thank you,
