How do I take the text from a TextView and format it for USD Currency?

Question

This is what I am doing -->

//get entered texts from the edittexts,and convert to integers.
Integer value1 = Integer.parseInt(sand1.getText().toString());


//doing a calculation
Double calculatedValue1 = (9.5*value1);


//set the value to the textview, to display on screen.
result1.setText("$"+ calculatedValue1.toString());

result1 in the TextView looks like this now: ##.#

I need it to look like $##.##

Change your code to something like this :

/get entered texts from the edittexts,and convert to integers.
Integer value1 = Integer.parseInt(sand1.getText().toString());


//doing a calculation
Double calculatedValue1 = (9.5*value1);


//set the value to the textview, to display on screen.
result1.setText("$"+ String.format( "%.2f", calculatedValue1 ));

basically, i have the user the code you see above ten more times. the user then presses a button and a calculation is done. From there a subtotal and total are printed. When the user enters numbers into the edittexts the first time, presses the button, then scrolls back up to thange their imputs, then presses the calculate button again the app "stops working" – Casey Jun 15 '16 at 20:02

Hello you could use this( Locale.US to format the number as USA standard and the %.2f for the decimal number) :

String.format(Locale.US, "%.2f", doubleValue);
