txt_total.setText(new DecimalFormat("##.##").format(itemamount));

public void onTextChanged(CharSequence s, int start, int before,
        int count) {
// TODO Auto-generated method stub
if (!edit_qty_code.getText().toString().equals("")
|| !edit_qty_code.getText().toString().equals("")) {
itemquantity = Double.parseDouble(edit_qty_code.getText().toString());
itemamount = Double.parseDouble(text_cost_code.getText().toString());

Well if the value of decimal number is dynamic and if not, then here is the solution. (This solution is for both unknown dynamic value or Known value)

 try {
        Double rounded= new BigDecimal(Double.parseDouble(getdecimalvalue())).setScale(2, RoundingMode.HALF_UP).doubleValue();
        textviewid.setText (String.valueOf(rounded) );

    }
    catch (Exception e){
        textviewid.setText (getdecimalvalue());
    }

For upto 2 decimal i give setScale first parameter as 2. Assuming getdecimalvalue() returns a string.

For dynamic suppose if the value is "12.5" then this will throw exception and in catch you directly show the value because value is only upto 1 decimal place after point.

Try this, it may help you.

float localresult =Float.parseFloat(itemquantity*itemamount);
BigDecimal bd = new BigDecimal(Double.toString(localresult));
bd = bd.setScale(2,BigDecimal.ROUND_HALF_UP);
bd.doubleValue();

then set it to textview , textview.setText(""+bd.doubleValue();)

I'm not exactly sure where in your code you are wanting to do this, but

String.format("%.2f", value);

should work.
