Please help about creating auto-animate

[booker0108]

Hi, Harism.

I am really appreciate your project and effort.

I have read the post before and you said the TouchEvent is the key to make auto-animate function, I would like to ask how can I make use of it as I have no ideas about how to pass a TouchEvent to the view.

Oh, after a large amount of search and read, I have found the method to simulate the TouchEvent and it should be available to preform the automatic animation.

I will try to add the function to the commit later when I complete this task.

Could you explain me how to simulate the animation performed on touch but automatically when I touch a button?

[SardarKhan299]

Can you provide the function for how to auto animate the page..

Please Harism comment the funcation which curl automatically on a button press

[androidqasim]

its really urgent

• Firstly, change a little bit code in onTouch() function:
  public boolean onTouch(View view, MotionEvent me) {
  ............
  case MotionEvent.ACTION_UP:
  if (mCurlState == CURL_LEFT || mCurlState == CURL_RIGHT) {
  // Animation source is the point from where animation starts.
  // Also it's handled in a way we actually simulate touch events
  // meaning the output is exactly the same as if user drags the
  // page to other side. While not producing the best looking
  // result (which is easier done by altering curl position and/or
  // direction directly), this is done in a hope it made code a
  // bit more readable and easier to maintain.
  mAnimationSource.set(mPointerPos.mPos);
  mAnimationStartTime = System.currentTimeMillis();

               // Given the explanation, here we decide whether to simulate
               // drag to left or right end.
               if ((mViewMode == SHOW_ONE_PAGE && mPointerPos.mPos.x > (rightRect.left + rightRect.right) / 2)
                       || mViewMode == SHOW_TWO_PAGES
                       && mPointerPos.mPos.x > rightRect.left) {
                   // On right side target is always right page's right border.
                   if (isAutoCurl)
                       mDragStartPos.x = 0;
                   mAnimationTarget.set(mDragStartPos);
                   mAnimationTarget.x = isAutoCurl ? mRenderer.getPageRect(CurlRenderer.PAGE_LEFT).left : mRenderer.getPageRect(CurlRenderer.PAGE_RIGHT).right;
                   mAnimationTargetEvent = isAutoCurl ? SET_CURL_TO_LEFT : SET_CURL_TO_RIGHT;
               } else {
                   // On left side target depends on visible pages.
                   if (isAutoCurl)
                       mDragStartPos.x = rightRect.right;
                   mAnimationTarget.set(mDragStartPos);
                   if (mCurlState == CURL_RIGHT || mViewMode == SHOW_TWO_PAGES) {
                       mAnimationTarget.x = isAutoCurl ? rightRect.right : leftRect.left;
                   } else {
                       mAnimationTarget.x = rightRect.left;
                   }
                   mAnimationTargetEvent = isAutoCurl ? SET_CURL_TO_RIGHT : SET_CURL_TO_LEFT;
               }
               mAnimate = true;
               requestRender();
           }
           break;
  

...........
}

• Then create function call curlToNextPage():
  public void curlToNextPage() {
  int x = getWidth();
  int y = getHeight() / 2;

   isAutoCurl = true;
   MotionEvent me = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, x, y, 0);
   onTouch(this, me);
   for (int i = 0; i < getWidth() / 5; i++) {
       x += i;// restamos xq vamos pa la derecha
       me = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_MOVE, x, y, 0);
       onTouch(this, me);
       try {
           Thread.sleep(10L);
       } catch (InterruptedException e) {
           e.printStackTrace();
       }
   }
   me = MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, x, y, 0);
   onTouch(this, me);
   isAutoCurl = false;
  

  }

From now on, you can use this new function to curl page automatically
