Answer 1

If you don't want to cast it you can keep it at double but truncate the trailing zeroes like this:

textView.setText(String.format("%.0f", 5.222));

Answer 2

Try something like this:

private final DecimalFormat decimalFormat = new DecimalFormat("#.####");
private final DecimalFormat noDecimalFormat = new DecimalFormat("#");

String decimalValue = decimalFormat.format(value);
String noDecimalValue = noDecimalFormat.format(value);

Or using NumberFormat instead of DecimalFormat:

 private NumberFormat formatter;
 // Set the properties for the number format that will display the values
 formatter = NumberFormat.getNumberInstance();
 formatter.setMinimumFractionDigits(4);
 formatter.setMaximumFractionDigits(4);

 String decimalValue = formatter.format(value);

 formatter.setMinimumFractionDigits(0);
 formatter.setMaximumFractionDigits(0);

 String noDecimalValue = formatter.format(value);

You can set the rounding mode you want like this:

noDecimalFormat.setRoundingMode(RoundingMode.DOWN)
formatter.setRoundingMode(RoundingMode.DOWN)

Answer 3

Try to use cast like this.

double number=32.1500;
int numbereditted=(int) number;
textView.setText("Number= "+numbereditted);

Or use decimal format.

double number=32.1500;
DecimalFormat df=new DecimalFormat("0");
textView.setText("Number= "+df.format(number));
