How much portion of the given text will be displayed in a TextView
i want to develop an ebook reader..
can i know how much text will be displayed on the given textview whose dimension is match_parent
.
or can i get the visible text of the textview... (if i copy the whole text on the textview)
i have tried various things like Paint:breakText
.. it returns me the chars to be displayed in given width,
but i dont understa开发者_如何学运维nd how many lines will the textview have... so i cannot determine how many times i should loop the Paint:breakText
..
also TextView:getLineCount
returns 0,
TextView:height
returns -1 (bcz i have set it to match_parent)
plz help me out wid this..
If you provide your textView's height with matchparent and enclose your textview within a scrollview, I think you can accommodate large amount of text within a single textview.
Maybe FontMetrics will help? You can see the doc for FontMetrics here: http://developer.android.com/reference/android/graphics/Paint.FontMetrics.html
