How do i get an input of time in milliseconds?

Question

private long START_TIME_IN_MILLIS;
private long TimeLeftInMillis = START_TIME_IN_MILLIS;

i have declared these variables, which is meant to store an input from an EditText, but in my OnCreateView i have this line

START_TIME_IN_MILLIS = edtInsertTime.getText();

but it gives me an error, how do I get the input of time in milliseconds and store it in START_TIME_IN_MILLIS?

Answer 1

You didn't post the error you received, and that would be helpful since it can be of hundred reasons..

Just looking at this code, you have variable of type long, ( which is a numeric type ), and what you get from edtInsetTime.getText()? , a type "Editable" according to the documentation, and you can't store Editable object in a long variable.

https://developer.android.com/reference/android/widget/EditText

public Editable getText ()
Returns Editable - The text displayed by the text view.

To get a long value from it, you first need to get a String from this EditText, then convert it to a long format, and then assign it to the variable.

Examplary code would be.

START_TIME_IN_MILLIS = Long.valueOf(edtInsertTime.getText().toString());

Breaking it down.

String text = edtInsertTime.getText().toString() returns the String value of an edittext

That value then can be converted to a long value by parsing the String to long, with methods like

Long.parseLong(text)

or

Long.valueOf(text)
