I would like to be able to create a path between two points by entering coordinates through two text fields and use the function I created, to create the path, using a button that takes the two coordinates entered as the end point.
when i try to insert the reference to the two text fields i have this error, how can i solve it?
my code is this below:

CodePudding user response：
A TextInputEditText is (as the docs say):
A special sub-class of
EditTextdesigned for use as a child ofTextInputLayout.Using this class allows us to display a hint in the IME when in 'extract' mode and provides accessibility support for
TextInputLayout.
It's a special kind of EditText that goes in a TextInputLayout basically (which you're not using).
So a TextInputEditText is an EditText (because that's its superclass), but an EditText is not a TextInputEditText, in the same way an Integer is a Number, but a Number is not an Integer - and if you assume a Number object is also an Integer when it isn't, it'll crash when you cast it to that invalid type.
You're using plain EditTexts in your XML (technically AppCompatEditTexts like in the error, they're automatically converted and AppCompatEditText is the superclass of TextInputEditText - don't worry about it, basically). So when you do
findViewById<TextInputEditText>(R.id.editTextLatitudine)
The view with that ID is an EditText and you're trying to cast it to a TextInputEditText, which it ain't. Cast fails, you get a crash!
You're not even using a TextInputLayout anyway, so you have no use for TextInputEditTexts. Just treat them as plain EditTexts in your code (which is what they are!) like in JustSightseeing's answer
CodePudding user response：
You cannot cast an editText to TextInputLayout. That is because they are different items with different types. Change these 2 lines of code:
private lateinit var editTextLatitudine: TextInputEditText
private lateinit var editTextLongitudine: TextInputEditText
and those 2:
// traccia percorso tra i punti degli editText
editTextLatitudine = findViewById<TextInputEditText>(R.id.editTextLatitudine)
editTextLongitudine = findViewById<TextInputEditText>(R.id.editTextLongitudine)
to:
// traccia percorso tra i punti degli editText
editTextLatitudine = findViewById<EditText>(R.id.editTextLatitudine)
editTextLongitudine = findViewById<EditText>(R.id.editTextLongitudine)
private lateinit var editTextLatitudine: EditText
private lateinit var editTextLongitudine: EditText
as shown here, AppCompatEditText extends EditText, so you just have to change the type of those and it should run
