I'm generating a book app, of sorts, that displays pages in a WebView
. I have Next/Previous ImageButtons
and a GestureOverlay
to detect left/right swipes.
When I want a page change I call:
private void changePage(int delta) {
currentPageIndex = currentPageIndex + delta;
if (currentPageIndex < 0) {
// negative index
currentPageIndex 开发者_StackOverflow社区= 0;
} else if (currentPageIndex >= listOfPages.length) {
// index requested is out of range of the list
currentPageIndex = listOfPages.length - 1;
} else {
// set values for page load
filename = listOfPages[currentPageIndex];
mWebView.loadUrl("file:///android_asset/" + filename);
}
}
'listOfPages' is a string array of my filenames and loadUrl() works great, but is there any way that anyone knows of to be able to have a page transition to simulate a simple page turn?
If anyone's interested, I found a way to do this.
I defined Animation
variables:
Animation slideLeftAnimation = AnimationUtils.loadAnimation(getBaseContext(), R.anim.slide_left);
Animation slideRightAnimation = AnimationUtils.loadAnimation(getBaseContext(), R.anim.slide_right);
And the slide_left
and slide_right
xml files are from the Android API tutorials.
Then, for left or right swipes, I used mWebView.startAnimation(leftOrRightAnimation);
before my mWebView.loadUrl(url);
call.
Hope this helps anyone else!
