将问题Android小部件解析为int

Question

Need help parsing, I have tried "porting" my dice roller project to Android using Android Studio, I have most of the controller values replaced with their android widget counterparts, one problem, I am not sure how to properly parse widget values to an Int. I have marked them with aligned left comments below.

modifier is an EditText
result is a TextView

I have tried many combinations and this is the most recent. The one that worked when it was pure java was .getValue().toString().trim() but I cannot use .getValue why is this?

public void onStart()
{
   super.onStart();
   percentile.setOnClickListener(new View.OnClickListener()
   {
     @Override
     public void onClick (View v)
     {
       {
          //issue is here
          int total = Nat20_core.roll10(cumulative.isChecked(),
                        Integer.parseInt (String.valueOf(modifier)),
                        Integer.parseInt(String.valueOf(result)));
          //end issue
          result.setText(String.valueOf(total));
        }
      }
    });
}

I have also tried this in a previous program as set

Answer 1

In EditText and TextView, the "value" is "text":

Integer.parseInt(modifier.getText().toString())

Answer 2

This is because there is no .getValue() method for EditText and TextView widget.

For EditText, you can use getText() which returns an Editable . So, you need to get the string from it using toString() . So, you will need to use:

modifier.getText().toString();

For TextView, you can use getText() which returns a CharSequence . You also need to get the string from it using toString() . So, you can use the above line too:

result.getText().toString();

Now, you need to convert the following code:

int total = Nat20_core.roll10(cumulative.isChecked(),
                        Integer.parseInt (String.valueOf(modifier)),
                        Integer.parseInt(String.valueOf(result)));

to:

int total = Nat20_core.roll10(cumulative.isChecked(),
                        Integer.parseInt (modifier.getText().toString()),
                        Integer.parseInt(result.getText().toString()));
