I'm trying to set a text in a TextView
from a List
of Strings
. I can see the value in the LogCat
, but when I put it in TextView
I get 0. What could be the problem?
EDIT My List
is not empty, I can see values in the LogCat
!!
List<String> listResult = new ArrayList<String>();
// here i'm putting some data
if (listResult != null)
{
for (int i=0;i<listResult.size();i++)
{
Log.i("position",listResult.get(i)+"")//i can see the componnent of the list
textView1.setText(position+1+"");
textView3.setText(listResult.get(i)+"");//I'm getting 0
}
Log.i("*******","***************");
Log.i("position",listResult+"")//i can see the whole list
}
This is the LogCat i'm getting :
05-20 11:39:07.970: I/position(21761): 0
05-20 11:39:07.970: I/position(21761): 2

The reason for getting 0 in TextView
is that when you call setText()
it sets a text replacing the one previously set, if any. So, in your case you just get the result of the last iteration, which is 0. In order to show the entire list in TextView
you should add a new text to the one previously added at each iteration using append()
method. The for loop
should look as follows:
for (int i=0; i < listResult.size(); i++) {
Log.i("position", listResult.get(i) + "")
textView1.append(String.valueOf(position+1));
textView3.append(listResult.get(i).toString() + " ");
}
