thanks serge, great communication.
right now its ok for me, because the code who does create the tags is
also from me :)
so i can be sure there is always a start and ending tag.
just for anyone who is interested here an extended version that does
allow to
search for several tags in a long string (for example, the first
appearance, the second ...)
When there is nothing found, it returns the string "!NULL!" (because
"" may also happen if
there is just nothing between an open and end tag :)
and finaly you can say it should short a long response ...
Now its finished for my purpose... so just like to share with you,
should u need something like that.
//TakeIt ("yourtag", TheSourceString, WhatPosition, length of
return)
public String TakeIt(String xtag, String xhtml, int xpos, int xmax)
{
int xstart = 0;
String xfound = "";
int xcounter = 0;
// xhtml = "hallo, <d>das</d> ist ein <d>test</d von mir
<d>an</d>
dich
do
{
xcounter++;
String x1tag = "<" + xtag + ">";
String x2tag = "</" + xtag + ">";
xstart = xhtml.indexOf(x1tag);
if (xstart != -1)
{
int x1len = x1tag.length();
int xend = xhtml.indexOf(x2tag);
if (xend != -1)
{
int x2len = x2tag.length();
if (xcounter == xpos) xfound =
xhtml.substring(xstart + x1len,
xend);
// cut till here
xhtml = xhtml.substring(xend + x2len);
} else
{
xfound = "!NULL!";
}
} else
{
xfound = "!NULL!";
}
} while ((xfound != "!NULL!") && (xcounter < xpos));
if (xfound.length() > xmax) xfound =
xfound.substring(0,xmax)+"...";
return xfound;
}
------
Also what I am thinking about, is there a Class List with several
such
simple Commands for Android that makes Live more easy?
I really think so start a small project with a class everyone just can
include in his
own project and wih several simple functions.
Right now I am still looking for a solution with my Listview and
Gallery Update
after a Thread..

You are welcome to help and share your sources ( please if possible
always with working source Code,
special Beginners like me are very happy about :)
