How to change number format in TextView

Question

If I add a a long double number into EditText, for example 1500000000, the Textview is displaying the number as 1.5E8. I dont want it to be displayed in this format, I want it to displayed as 150000000. How could I change that?

Answer 1

You should use String.valueOf() method, so you get a String representation of the big number. In your case, it will be as below:

textview.setText(String.valueOf(1500000000));

Answer 2

You should use DecimalFormat to format it.

        {
            double doubleA = 1500000000;
            DecimalFormat decimalFormat = new DecimalFormat("#.##");
            txtv_test.setText(decimalFormat.format(doubleA)); //show 1500000000
        }
        {
            double doubleA = 1500000000.123;
            DecimalFormat decimalFormat = new DecimalFormat("#.##");
            txtv_test.setText(decimalFormat.format(doubleA)); //show 1500000000.12
        }
        {
            double doubleA = 1500000000.1;
            DecimalFormat decimalFormat = new DecimalFormat("#.##");
            txtv_test.setText(decimalFormat.format(doubleA)); //show 1500000000.1
        }
        {
            double doubleA = 0.12;
            DecimalFormat decimalFormat = new DecimalFormat("#.##");
            txtv_test.setText(decimalFormat.format(doubleA)); //show 0.12
        }
