numberformatexception - Invalid Double. Number format exception in android

Question

I have this in xml.

<EditText
                android:id="@+id/creditlimitfield2"
                android:hint="0"
                android:inputType="numberDecimal" />

So, the default value for edittext is 0.

in code, I have this

creditlimit = (EditText) findViewById(R.id.creditlimitfield2);
double credit_limit = Double.valueOf(creditlimit.getText().toString());

Alternately, I have tried:

double credit_limit = Double.parseDouble(creditlimit.getText().toString());

And

double credit_limit = new Double(creditlimit.getText().toString());

When I run the program, It gives the error of

Numberformatexception. Invalid double "".

Please be reminded that the field is not empty. Any suggestions would be helpful.

Answer 1

getText() does not return the value inside android:hint. So you are trying to convert an empty string as double. use android:text property instead.

<EditText
    android:id="@+id/creditlimitfield2"
    android:text="0"
    android:inputType="numberDecimal" />
