无法比较字符串变成整数java

Question

So, I need to change my textView color to red if it's more than 0 and to green if it's less than 0, but I can't write if statement properly, because textView is a string, but I've changed it to int.

textView.setText(textView + "");


        if(textView > 0) {
            textView.setTextColor(this.getResources().getColor(R.color.colorAccent));
        }
        else if (textView < 0){
            textView.setTextColor(this.getResources().getColor(R.color.colorPrimary));
         }
        else {
            textView.setTextColor(this.getResources().getColor(R.color.colorPrimaryDark));

    }

To work with the String inside the TextView (Which is not a String , it's a View ) you first need to access it with .getText().toString() . So if you want to work with the value of the textView like an integer, do the following:

String stringValue = textView.getText().toString();
int intValue = Integer.parseInt(stringValue);
//Now do your logic.

If you want to set the value again to the view, make sure you're passing a String and not an integer.
