android - Find exact coordinates of a single Character inside a TextView -


currently i'm using paintobject.measuretext(textcopy.substring(0,i)) while iterating through copy of textview's text. example, measuretext("abc".substring(0,1)) give me relative x coordinates of 'b'. y coordinate layout.getlinetop(). working not accurate x coordinates non-monospaced fonts. can calibrate little, on each device works differently.

the best solution can think of overwrite class responsible drawing textview on screen and, hopefully, coordinates of each character drawn screen.

does know class need overwrite accomplish this? or maybe other creative solution?

well seems sort of bug of paint.measuretext() or other deeper class. have finally found way around it:

layout.getprimaryhorizontal(int offset)

this easy. iterate through layout using length of text uses.

it return the x of character regardless of line position. lines i'm still getting layout.getlinetop(). way, if using layout.getlinetop(), note there strange behaviour, possibly bug. have submitted bug report here.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
