The idea of Android Reader (i)

Recent work in business has met the needs of Android readers. The first question is how to divide a novel into content that needs to be displayed on each page, depending on the size of the screen. To put it simply, the string of a whole novel becomes a string["string that is exactly what each page can display."

First, we want to get the wide-height--width,height of the display area.

Then, the number of rows that can be displayed on a screen rowcount the current font size is calculated.

Next, set the font size, alignment

        New Paint (paint.anti_alias_flag);        Mpaint.settextalign (Paint.Align.LEFT);        Mpaint.settextsize (14);

Next, remove the first paragraph:

        int paragraphend = str.indexof ("\ n")        ; = str.substring (0, Paragraphend);

And get the first line to show how many words:

        int true NULL );        LOG.D ("tag", "The End index is =====" + breakindex);         = Str.substring (Breakindex);

If this paragraph is finished, remove the paragraph; If this page ends and the paragraphs are still not displayed, the remaining strings will be spelled back to the original content for display.

This completes the basic idea of a reader page display.

Done.
