I have a listView in my application and at some point during the execution, I want to highlight a specific row. I found some examples but I keep getting errors. Here is my code:
public void animate(int pos){ //pos:position of the row in the list
lv1=(ListView)findViewById(R.id.listView1);
Animation animation = AnimationUtils.loadAnimation(getBaseContext(), R.anim.scale);
((View)lv1.getItemAtPosition(pos)).startAnimation(animation);
}
and scale.xml
<?xml version="1.0" encoding="utf-8"?>
If anyone can help with this I would really appreciate it.
EDIT: I want to give an additional information I just found out. I get a NullPointerException when I run the code. Following line causes the exception
((View)lv1.getItemAtPosition(pos))
I cannot get the items in listView. I changed my program as follows:
public void animate(int pos){ //pos:position of the row in the list
lv1=(ListView)findViewById(R.id.listView1);
View v=lv1.getChildAt(pos);
Toast.makeText(getBaseContext(),Boolean.toString((v==null)),Toast.LENGTH_SHORT).show();
}
It always displays "true". I didn't understand where the problem is stemming from.
