I also want just enter only number form number pad. if i am select any non numeric number then EditText will not accept it.

if any suggestion, it would be great. Thanks.

you can use regex so it should be 1024.22 something like this?? — Raghunandan, Aug 04 '14 at 12:22

Have

android:inputType="numberDecimal"

attribute for EditText

You can use a regex for the validation part. The below is only a sample

You can check with a online regex tester @ http://regex101.com/r/uG9aF6/1

String input = "1024.22";
String pattern = "([0-9]{4})(\.)([0-2]{2})"; // 4 digits followe by . followed by 2 digits
Pattern r = Pattern.compile(pattern);
Matcher m = r.matcher(input);
if(m.matches())
{
   System.out.println("Validated");
}
else
{
   System.out.println("Not Validated");
}

android:inputType ="number" and android:maxLength="6" in xml layout of editText will popup the keypad of digits and only six digits can be entered in the editText

like this

<EditText
        android:id="@+id/myinput"
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:inputType="numberDecimal"
        android:maxLength="6"
        android:hint="@string/somestring"
        android:layout_weight="1"
    />

This should help but he also wants to have a specific format for the input to be enforced. – kabuto178 Aug 04 '14 at 12:26

Try this pattern ^([0-9]{1,4})(.[0-9]{1,2})?$

it accepts up-to 4 digits before . and only up-to 2 after

You can check your period position. For example in your case

char value = 'anychar' ; if (edittext.gettext.toString().indexOf(value) == 4 ){ // your logic goes here }

    <EditText
    android:id="@+id/edit1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:inputType="numberDecimal"
    android:maxLength="7" />

4 - digits for Number , 1 - digits for .(Dot) and 2- Digits for fraction Number. Its also Number Decimal SoftKeyboard when you made focus on Edittext.

if you want to focus on Edittext auto use this:

          android:focusable="true"
