Answer 1

你可以DecimalFormat这样使用：

Double number = Double.valueOf(text);

DecimalFormat dec = new DecimalFormat("#.00 EUR");
String credits = dec.format(number);

TextView tt = (TextView) findViewById(R.id.creditsView);
tt.setText(credits);

 decimal a = 12000000;
        Console.WriteLine(a.ToString());
        //output=> 12000000

        Console.WriteLine(a.ToString("N"));
        //output=>12,000,000.00

        Console.WriteLine(a.ToString("N1"));
        //output=>12,000,000.0

        Console.WriteLine(a.ToString("N0"));
        //output=>12,000,000

尝试将此代码添加到KeyUp您的事件处理程序TextBox

private void textBox1_KeyUp(object sender, KeyEventArgs e)
{
    if (!string.IsNullOrEmpty(textBox1.Text))
    {
        System.Globalization.CultureInfo culture = new System.Globalization.CultureInfo("en-US");
        int valueBefore = Int32.Parse(textBox1.Text, System.Globalization.NumberStyles.AllowThousands);
        textBox1.Text = String.Format(culture, "{0:N0}", valueBefore);
        textBox1.Select(textBox1.Text.Length, 0);
    }
}
