                if (View.getVisibility() == android.view.View.VISIBLE) 
                        View.setVisibility(android.view.View.INVISIBLE);
                        else if (View.getVisibility() == android.view.View.INVISIBLE)

Try This:

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:onClick="abcd" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:onClick="abc"
        android:text="Button" />
</LinearLayout>



public void abc(View v) {
    v.setVisibility(View.INVISIBLE);
}

public void abcd(View v) {
    v.findViewById(R.id.button1).setVisibility(View.VISIBLE);
}

Invisible Items don’t receive on-click event. So the only way you can receive a click on invisible is by receiving on some other view in place of the invisible view. The above solution wraps the button in a layout, so when button is invisible the on-click is passed on to layout, which handles the event and do accordingly. If you have a high usage of such layout you can also create a custom button with above mechanism.
