Android change textView after inflating another View

Question

Hi i'm trying to change a textview in an inflated view but the app crashes.

What i'm trying to do is fill the text views with the contents from the variables HomeTeam and AwayTeam these variables aren't null because when i log them the have names in there.

So my question is how do i change a text view and replace its contents

heres what I've tried

for(int t = 0; t < 1; t++){

               resultsDict = jArray.getJSONObject(t);
              String HomeTeam = resultsDict.getString("hometeam");
              String AwayTeam = resultsDict.getString("awayteam");

              Log.v("lc","hometeam" + HomeTeam);
              Log.v("lc","awayteam" + AwayTeam);


           }


           resultsView = LayoutInflater.from(getBaseContext()).inflate(R.layout.resultscell,
                     null);

           TextView homeTeam = (TextView) findViewById(R.id.HomeTeam);
           homeTeam.setText(HomeTeam);

the inflated view

Answer 1

You need to change:

TextView homeTeam = (TextView) findViewById(R.id.HomeTeam);

To this:

TextView homeTeam = (TextView) resultsView.findViewById(R.id.HomeTeam);

why? because HomeTeam is available in your inflated view. So, you need to refer to your inflated view/viewgroup when finding the child view
