Get integer value from dimens.xml resource file in Android

Question

I have an EditText which is decimal and I set its length using android:maxLength property in xml:

Answer 1

With your example, why don't you use this method?

XML

<integer name="quantity_length">10</integer>

JAVA

getResources().getInteger(R.integer.quantity_length);

Answer 2

Why not store the integer in res/integers.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <integer name="quantity_length">12</integer>
</resources>

And to access the values in code

int myInteger = getResources().getInteger(R.integer.quantity_length);

Or in XML

android:maxLength="@integer/quantity_length"

Answer 3

You dont need a TypedValue use the following

(int) this.getResources().getDimension(R.integer.quantity_length);

Answer 4

Use:

Integer.ParseInt(digitsBefore);

Keep an eye on the paths...

Answer 6

int max = getContext().getResources().getInteger(R.integer.quantity_length);
