Displaying textview as list element, for this textview getting values by returning values from a method getValues()so setting text fot textview like this t1.setText(getValues());these values are like (123 kms,12 kms,13 kms,15 kms,198 kms,135 kms,456 kms,12 kms,135 kms,147 kms,....)i want to compare all elements with first one and if it is grater than first element that text color is RED ,if it it less than first element it is BLUE ,i tried something like this and got two lists.
What i tried
List<Integer> myList = Arrays.asList(12,34,45,23,45,7,68,4,345,56,67,4,999,454,6,76,0);
Iterator<Integer> iter = myList.iterator();
List<Integer> lessList = new ArrayList<Integer>(), biggerList = new ArrayList<Integer>();
Integer firstItem = iter.next();
while (iter.hasNext()) {
Integer currElement = iter.next();
if (firstItem.compareTo(currElement) > -1) {
lessList.add(currElement);
} else {
biggerList.add(currElement);
}
}
here i am not getting how to set text of textview and two colors for same textview. help me.
tried code something like this
if(odo_chk_num>400)
{
if(t2!=null)
{
t2.setTextColor(Color.RED);
t2.setText(getValues());
}
}
else
{
t2.setTextColor(Color.BLACK);
}
but here first if condition executes then all texts color changing to RED,but what i need text should be RED based on condition only. ADAPTER CLASS
