Question

I want to know whether there is any option to describe textview color based it is positive or negative number through xml only.
if not possible through xml then how can i do it in java as my code make number go positive to negative and viceversa many time and color remain as of starting of App

Answer 1

Like this: (with myTV being your TextView)

int number = Integer.parseInt(myTV.getText());
if(number<0){
     myTV.setTextColor(getResources().getColor(R.color.negativeColor));
}
else{
     myTV.setTextColor(getResources().getColor(R.color.positiveColor));
}

There is no way to do this in XML…
