i want to change the currency from USD to SAR or any other currency.
How i can change it.

} private void displayPrice(int number) { TextView priceTextView = (TextView) findViewById(R.id.price_text_view); priceTextView.setText(NumberFormat.getCurrencyInstance().format(number)); }
Change currency?
Same message on comment but slightly more info.
where is properties??
By default the NumberFormat.getCurrencyInstance().formate() give us dollar sign if you want to your choice of sign then look underneath
code for pkr i just change the method like this
public void displayPrice(int price){
TextView textView=(TextView)findViewById(R.id.price_value);
Locale pakistaniRupees=new Locale("urdu","pk");
NumberFormat pakistaniFormat=NumberFormat.getCurrencyInstance(pakistaniRupees);
textView.setText(" "+pakistaniFormat.format(price));
}
Why there is so many errors in this code?

what should i do with these problem
Add--- import.java.text.NumberFormat in your code

For all of those who are trying to get currency in their locale this will help
The lines of code you see below is exactly the same as display method the one you see in quantity_text_view
private void displayPrice(int number) {
TextView priceTextView = (TextView) findViewById(R.id.price_text_view);
priceTextView.setText(NumberFormat.getCurrencyInstance().format(number));
}
The major difference here is this line
priceTextView.setText(NumberFormat.getCurrencyInstance().format(number));
Now what exactly this line of code does is,it's adding the currecy symbol to your calculation like this $10.00
This whole line is just to get currency sign **(NumberFormat.getCurrencyInstance().format()
Now to change currency to your locale there are two ways:
Easy Way
- priceTextView.setText("₹"+number);
In this you provide your currency symbol directly inside these "" marks
This line is exactly same as one you see in display method but here your adding your currency sign to the number
In this way you don't get decimal numbers what i mean is you get like this ₹10 instead of this ₹10.00
Udacity Way
- Like i said above
This whole line is just to get currency sign (NumberFormat.getCurrencyInstance().format(number).
All we have to do is change it to your local like this
priceTextView.setText(NumberFormat.getCurrencyInstance(new Locale("en","IN")).format(number));
Above i've added this new Locale("en","IN") new line inside of getCurrencyInstance()
By adding that line we are saying i want the currency to be in other local instead of default one with this new Locale()
Now we need to tell in what local we want the currency to be.
We say that by adding these "en" , "in"
-
"en" -This is language and i want it to be in ENGLISH.
-
"IN" -This is country since i'm INDIAN i say "IN"
HOPE THIS WILL HELP , THANK YOU!
what is wrong ?

Just look at the error message it tells you.
... Invalid character ....
<String name=...
can't use special characters like "$" or "#" or white character etc.
The resource name must start with a letter.

That was really awesome Thanks!
can some one help me
TIP:
The currency used is the one your phone uses, not what is set on your computer. Some phones don't allow you to change the currency explicitly, but your selected language on the phone dictates this, for example choosing English (United Kingdom) will automatically set the currency to "£" (Pounds).
On a Samsung phone in most cases this can be set under Options->Controls->Language and Input
Thnx Buddy!!! It Resolves my problem.
please help !
@chekwon78 Do try adding a TextView in activity_main.xml and assign it an id like this
android:id="@+id/price_text_view".
Thanks soo much ,it worked for me
Hello,
Need your help to solve the numberFormat error after adding the "Add unambiguous imports on the fly"
It's ok, solved by adding "import java.text.NumberFormat;" . thanks.
error: invalid method declaration; return type required
} displayPrice(2*5);
^
don't why my app is crashing after clicking on the ORDER button
How do I resolve this error?
Code of [chetan081] approach
private void displayPrice(int number) {
TextView priceTextView = (TextView) findViewById(R.id.price);
priceTextView.setText("₹ "+ number);
}
How do i resolve this error
After latest update of Android studio it should be this code in Kotlin:
/**
* This method displays the given price on the screen.
*/
private fun displayPrice(number: Int) {
val priceTextView = findViewById(com.example.justjava.R.id.price_text_view) as TextView
priceTextView.setText(java.text.NumberFormat.getCurrencyInstance().format(number))
}
Do you know that this course is in Java and not kotlin?:) You can find some solutions on StackOverFlow.
One of your search could be like this: Unresolved reference in kotlin with id and activity_main
Solution could be:
import android.Rsolved the issue.
