how to know when the next/previous page has comple

问题:

I have implemented Page Curl Effect by harism in my application.

Now I need to do some text animation on top of the pages. I am able to put the text over the pages and also able to animate. However, I need to know when the curl effect has completed and next/previous page has completely loaded, as I need to make the TextView invisible and stop the animation when the page curl effect is in process.

I have been struggling to find when the page is completely loaded/page curl animation has finished. I have also posted my question on github harism repository in the issues section and android-developers forum on Google Groups, but have not received any replies. Hope to get some help out here.

Thanks!

There is method onDrawFrame in CurlView class. There you can see that parts of code where you can determine if page has been completely loaded:

 if (mCurlState == CURL_LEFT) {
         --mCurrentIndex;
// left curl has been completely loaded
//here you can add some code 
    }

and if it is right page curl

 if (mCurlState == CURL_RIGHT) {
     ++mCurrentIndex;
// right curl has been completely loaded
//here you can add some code 
    }
