[android-developers] Re: Image loading from remote problem
Kumar,
I have already checked your pages. Its shows example for drawable
which you have on mobile.
I want to load remote image. As remote image loading takes long time.
UI hangs up till the time.
I have also seen that you have written saying that we can pass null
and open new thread which downloads image to local.
Replace's the path to local file in html and then reset the text in
TextView.
This works fine when textview has one image but when our text has 2/3
img tags. Each time getter is called and 2/3 new threads get open and
2/3 times text is reset.
Lets imagine case where means while image downloads in new thread then
user goes to other activity and the one which we opened is destroyed.
Also the case where in same acitivty i have 2/3 pages like which has
next and prev button. So the image comes bit late and then the thread
will take other text and replace it somewhere else
I dont know but Im going it in big confusion. Is there some direct
widget for this ?
I dont want to use webview as I have some other things which gets
disturb because of webview. Need to it in textview only.
