Getting a Double value from an EditText

Question

I want to input a numeric value into an EditText box. The InputType is specified as "numberDecimal|numberSigned". The code I've found that works is:

mLatitude = txtLatitude.text.toString().toDouble()

This seems unnecessarily convoluted. Can it really be necessary to convert first to a string then to a double? Is there an easier way?

Answer 1

Double.parseDouble() would not accept Editable that is returned by txtLatitude.text.

You can create your own extension if you want

fun Editable.toDouble() = toString().toDouble()

fun test() {
    mLatitude = txtLatitude.text.toDouble()
}

Answer 2

There is no another way. For convenience you can create an extension function on EditText :

fun EditText.getDouble(): Double = try {
    text.toString().toDouble()
} catch (e: NumberFormatException) {
    e.printStackTrace()
    0.0
}

And use it like this:

val latitude = editText.getDouble()
