how to load parsed data into an existing textview(existing layout) in android
hii every buddy , am not getting how to load parsed dat开发者_Python百科a into an existing textview(existing layout) in android, insted of loading data to the new textview like how they r doing in the following tutorial(check the following link)
check this link for tutorial
In the tutorial they do:
TextView something = new TextView(context);
As you don't want to do so (good decision), you get the reference to the existent TextView
:
TextView something = (TextView)findViewById(R.id.the_id_you_gave_it_in_the_xml);
// then:
something.setText(theParsedString);
Try this code using existing Layout
Textview name=(TextView)findViewById(R.id.textView1);
String txt="";
for(int i=0;i<sitesList.getName().size();i++)
{
txt=txt+sitesList.getName().get(i).toString();
}
name.setText(txt);
Sowmya It seems that you are creating multiple textviews & trying to update those textviews .In that case you need to use setTag() and getTag() .
There is an example you can find here
Regarding your answer:
we r declaring textview array so am unable to load to existing textview
I have never implemented such a textview array instead the best practice would be to
for (String s : stringarray) {
TextView tv = new TextView (this);
tv.setText(s);
tv.setTag("1");
linearlayout.addView(tv);
}
*EDIT:*For those enthusiast out there I found 2 more methods:
One is using setId() to manually set ID of that textview & then find it by findViewById()
Another method(is though not implemented by me , but is a suggestion by my colleague so dont kill me if it doesn't works) is to store textview objects in an arraylist & then access them & do whatever you want whoa!
