手机参数：
API 15；480x800；中兴。。。
修改过程：

1. 把 drawable 目录下的图片分别放到 hdpi、xhdpi、xxhdpi 目录下。
2. 源码还没细看，所以把 #19 中提到的问题用很粗鲁的方式修改了，该修改方法并不可靠。如下

public void set(int w, int h, int maxCached) {
        pageWidth = w;
        pageHeight = h;

        int newIndex = LARGE_BG;
        if ((w <= 480 && h <= 854) ||
            (w <= 854 && h <= 480)) {
            mBGSizeIndex = SMALL_BG;
        }
        else if ((w <= 800 && h <= 1280) ||
                 (h <= 800 && w <= 1280)) {
            mBGSizeIndex = MEDIUM_BG;
        } else {
            mBGSizeIndex = LARGE_BG;
        }

        mIsLandscape = w > h;

        if (maxCached != mQueueMaxSize) {
            mQueueMaxSize = maxCached;
        }

        if (newIndex != mBGSizeIndex) {
//            mBGSizeIndex = newIndex;
            synchronized (this) {
                cleanQueue();
                notify();
            }
        }
    }

3. 参考 android_page_curl 中的一部分逻辑，即计算最邻近的 2 的指数部分，修改了 createBitmap 的宽高参数。

说明：
1 和 2 主要是为了节省内存，担心老手机带不动，3 是因为刚开始在手机上调试的时候，图片加载不出来，故尝试使用该方法。没想到居然成了==。

How can we zoom an image or add custom controllers like go to page 6?

After running this project installed on a mobile with nothing shown on the screen

if (!page.isFirstTextureSet()) {

   drawPage(mPageNo);

   page.setFirstTexture(mBitmap);

}

can it be used with glide or other imageloader framework？

Hello.
First of all, thank you for making this open-source.

I would like to have a way to navigate to a particular page.
When analyzing source, page movement seems to be possible only through touch.
how to move particular page?

Is it possible to make the curl effect like Google Playbooks apps?

Sample

I have the two layout in my activity . I want to implement the page flip. So can you give me the idea for implementing this library .

I'm using the library to present Arabic's book, left to right curl is a necessity. I saw it on two pages mode, but is there any way I can use it for one page mode? Much like a reversed version of the default one page's curl. Regards.

When I open the Sample in the Android Emulator(API 25), it displays a black screen and this error is displayed in the Run tab of the Android Studio.

Hi There,

It's so nice to see your library. I'm trying to customized it. After research couple day, I still have some questions:

1. How to determine which page that user move finger in (left page or right page)?
2. How is clickToFlip() works?, I want to know that because I want to detect the action click to flip the page.
3. Can I use the pageFlipView as a customize view in layout? It's seem wrong Point X Y when I'm trying to do that.

I am using this library in a sample app and found that the page flip doeant work in landscape mode. I tried the semo app on play store and found that portrait mode works but landscape mode shows black screen as earlier reported. I am stuck here. I wish i could fix it. Can someone please help me. Many many thanks in advance.

I need to render pages sequence wise....
with singlepagerender i just changed getrandombitmap with pagenumber....

forward flipping working fine rendering next image.

but backward flipping not taking previous image its showing nextimage

Hi,
in demo your bitmaps in memory are astronomically huge as they are in "drawable" folder, which is "drawable-mdpi" and if you run it on modern xxxhdpi phone, you will get multiplier * 4 (i think) of each dimension, there fore each bitmap is 16times bigger in memory (124mb+ bitmaps)

Hi I am trying to update the text of my current page when a button is clicked.

I have the button working but I can't get the page to redraw with the new changes.
How can I redraw the current page on screen? Thank you.

I'm searching some of page flip animation recently, and found your great work in android 👍

but I'm not familiar with native code and also new in Opengl... :(

just curious is it possible to implement it into React Native (with gl-react-native-v2)?

if it is possible, I might need to learn native code and try to implement it into React Native

again thanks for your great work 👍

By the end of this method, variable mBGSizeIndex will always have value equals to LARGE_BG. Is this by intention? If it is, we could rewrite this method like below:

public void set(int w, int h, int maxCached) {
    mIsLandscape = w > h;

    if (maxCached != mQueueMaxSize) {
        mQueueMaxSize = maxCached;
    }

    mBGSizeIndex = LARGE_BG;
    synchronized (this) {
        cleanQueue();
        notify();
    }
}

Regards.

I want to write text in every page. please guide how I put to each page the text ?

I having trouble to add supportmapfragment to canvas in this library.
To add view such as TextView or Button is not problem, but when i define supportMapFragment in mainActivity and try to insert to canvas, i always getting error no view found for id.

how to do that actually?

Thanks in advance

Hi, first of all amazing for, however I need to customize bitmap loading logic.
Can you please give me pointers as how to implement if bitmap wants to be loaded asynchronously, say from network, I see that LoadbitmapTask.getBitmap is synchronous. (not thinking about decoding)

• maybe some callback to request ahead bitmaps so they can get preloaded?

Thanks you

仿真翻页效果想集合在已经做好的ViewPager上使用。有范例吗？

Is threre any way to update firstTexture if it is already set and pafeFlip is doesn't done yet?

I try with getFirstPage().deleteAllTextures(); but it produces memory leak and after many pafeFlip memory app increase a lot.

Hii eschao,
thanks for wonderful library .but what about loading image from server not from local can we do this.
if we can then how to do please provide some directions.

thanks

Hey its a wonderful library . I am trying to implement it, but the library does not the show pages in sequence I declared in array. And when i go to previous page their is some other random page. I want to maintain the sequence just like a book. Can you help on this.

does it support video play ?

I'm using the library to create "video book". I want to show the custom view (page) by custom xml. The layout contain videoView object. I try override drawPage() and add video object , but throw the exception [java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() ] . how can change to page[Canvas+bitmap] to video object?

手机是Smartisan T1，错误信息如下

On api level 19 I'm constantly getting

InputEventConsistencyVerifier: TouchEvent: ACTION_DOWN but pointers are already down.  Probably missing ACTION_UP from previous gesture.
  in android.view.GestureDetector@ad008e20

this causes some onDawn events not to register, so screen does not respond.

How to expand? smoothing pages, scrolling pages, and so on

Big Brother ,This project in Xiao mi 3 phone is black Screen,I don't know to how find the bug, Can you
help me?

Would be great to have a sample on Google Play Store :)

how do i get going to a specific position?

求教。

Hi

Could you please let me know how can I get the bitmaps in an order ?
In the LoadBitmapTask class there is a method getRandomBitmap() which is generating bitmaps randomly.
How the code should be written if I want to display them in a specific order ? (like the pages in book, which has an order).

I need to provide RTL support for LEFT to RIGHT page flipping. Would you please help?

How to add number fade in animation . ? with thi Library

I am really stuck with this issue

Your help would be appreciated.

We found that the drawPage method, located inside the SinglePageRender on the sample app, displays the current page in text.

If the current page is three, the text will show three.

I would like to change the number on the current page without flip it.

What should I do?

I need to implement the text highlight on pages to copy it (for example). I'm clicking on text (eg "First page" which is default) and hold it, but have no action. Is it really to use a TextView rather than Bitmap or I missing something?

Thanks in advance.

Is it possible to add pinch-zoom functionality without breaking existing touch listeners?

Please guide me how would i be able to play a .gif file in this example. As you are only dealing with Bitmaps. Is there any way to have the same effect on Custom .xml Layouts?

Hi i'm a newbie with open gl. I use your example and want to zoom with two fingers a picture. I have add in code ScaleGestureDetector and Listener. Where should i change scale ? Thanks.

Current version is pure Java, although its performance is good enough for most popular android devices, I still want to implement a JNI version to see how much performance we can improve from native codes!
