现在我做的项目是这样子的。 内容是分开的，按照章节来，每次进去的时候都是先从后台获取章节内容然后loadStr() ，你上次写的这个接口（再次感谢~）. 现在遇到的问题是：章节列表（这个也是从后台获取的），然后点击了根据章节id又去后台获取内容。如果页面没有滑动过，直接重新loadStr()页面的数据会切换到新获取的内容。但是只要滑动过后内容就无法更换。有没有什么方法把内容清空重新加载的啊。

看了一下代码，关键代码似乎是DrawPrepareTask。

这个现在能读取sd卡里的TXT文件吗？

翻页多张后，出现滑动到下一页内容依旧是当前页，退出重新进入后就没有了，只要滑动页数够多，基本每次都会出现

不是text，直接放String

我这边想添加一个翻书到最后一页的提示，好像没有翻书翻页的监听方法。。。要加在哪里

部分文本会全部乱码

默认的背景是白色，切换其他颜色后好像不能恢复

hi，你好，感谢分享源码！我是小白一枚，想修改下特定文字的样式，但是找不到你项目中关于修改英文和数字颜色的代码，请问下这部分代码在哪里？(位置越具体越好)

请问一下，遇到\n的时候不换行怎么处理的

现在默认是从左往右的

使用自定义TxtReaderView时，默认的文字排列是竖向的，如何设置成横向排列的。
使用自定义TxtReaderView时，如何设置章节列表？因为我是网络获取的小说内容，可以获取到所有章节，然后获取制定章节的内容。

楼主能不能简单说下实现原理

感谢 @bifan-wei 分享代码，本人小白，看楼主是以字符为对象保存的，请问英文小说不断词自动换行，好不好修改啊

部分文本会全部乱码

现在的弄的是在
void onTextChanging(float x,float y,String selectText);
添加一个坐标，
然后
public void onTextChanging(float x,float y,String selectText) {
if(startCopy)
{
copyX = x;
copyY = y;
startCopy = false;
Log.e("LOG"," copyX = "+copyX+" copyY = "+copyY);
}
}

只选取第一次的坐标，得到后
copyTextWindow.showAsDropDown(mTxtReaderView,(int)copyX,(int)copyY);

这样大概就能显示在选择字段的中间位置。
在
ClipboardManager copy = (ClipboardManager)
getSystemService(Context.CLIPBOARD_SERVICE);
// 将选取的内容放入剪切板
copy.setText(content);
copyTextWindow.dismiss();
之后 怎么退出选取模式呢。

有两个疑问请教:
1loadTxtFile(Context context, String FilePath, String FileName)好像有问题
HwTxtPlayActivity.loadTxtFile(this,"${getExternalStorageDirectory()}/storyReader/末日乐园","第一章灰姑娘的恐惧.txt")访问失败,提示文件不存在
HwTxtPlayActivity.loadTxtFile(this,"${getExternalStorageDirectory()}/storyReader/末日乐园/第一章灰姑娘的恐惧.txt")访问成功

2.如何设置编码,上面的文件是以UTF-8写入的,读取时是乱码
类似file.appendText("somecontent", Charsets.UTF_8)

作者删除项目了？

请问使用HwTxtPlayActivity能不能实现保存进度和下次打开的时候跳转过去

大佬
使用TxtReaderView的setStyle的时候改变背景颜色为黑色 字体为白色时 实际上背景变成蓝色 字体颜色也没有变化
在使用setTextSize设置字体大小时也没有变化
不知道什么情况

为什么字体很单薄且模糊呢？跟支持粗体有关吗？

如果我想要加入书签功能，请问我该怎么做

有许多厂家需要引流。阅读的时候能否在下方加一个广告条呢？

1. LoadTxtFile建议开头L小写
2. 建议可以用Gradle依赖项目

这个库我使用了，但是要是问到是如何实现的感觉还是不太好理解，paragraphindex和chartindex是如何确定进度的啊，然后每个页的字符数量都是确定的吗？

类似于QQ阅读的仿照翻书效果。
