自动翻页延时设置改进建议 #406

nobk · 2019-11-04T10:33:48Z

目前是延迟N秒翻页，但由于每章分几页显示，最后一页空白行可能较多，依然等待N秒不太合理。而且由于不同书籍分行和排版的原因，哪怕满页的字数差异也可能很大。
因此我建议将参数由N秒/页改为字数每分钟(CPM)。按照当前显示页的实际字数和设置的CPM计算该页停留的秒数，这个计算量很小，对现代处理器而言完全不算什么开销，但体验会比现在固定秒数翻页要好些，而且读者对自己的阅读速度也能心里有数了。

自己改好了，每章最后一个短页会因字数少翻页快些，完全按CPM来计算每页停留时间。设置的CPM范围在200到2000，我的阅读速度在620左右，默认值给的500。

progressBarNextPage进度条如果是纵向的，在屏幕左或者右边沿，从上往下走，比起现在的横向进度条，更容易让读者判断自己的阅读速度是否跟得上进度，而且不需要抬眼看进度并且做横纵对比转换。

nobk · 2019-11-10T14:20:00Z

如果进度条过2/3，就提前翻半页，显示下一页的上半部分，也能给读者一个比较好的过渡，并避免提前一两秒看完的空等时间，增加阅读的连贯性。

试着改了一下能把进度条竖起来且进度从上往下走，但在屏幕正中而且头部跑到屏幕外面去了，不知道怎么把它放在设想中的书页左侧或者右侧，而且高度正好对应文字，特别是最后一页高度正好对应结尾文字。

@gedoor你改的
app/src/main/java/com/kunfei/bookshelf/view/popupwindow/ReadAdjustPop.java
第83行漏掉了

+        hpbClick.setMin(readBookControl.minCPM);

导致CPM范围设置控件的最小值是0。
