变量'btnsave'是从内部类中访问的，需要声明为final

Question

I have the above error on my code. I have tried fixing this by declaring my btnsave as final, but then I get two other errors saying:

Unknown class: 'btnsave'

Not a statement

Any idea how I fix this error?

btnsave = (Button)findViewById(R.id.button);
            btnsave.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {

                    int clicks = 0;
                    clicks++;

                    if (clicks >= 5){
                        btnsave.setEnabled(false);
                    }

                    SharedPreferences prefs = getSharedPreferences("myPrefsKey", Context.MODE_PRIVATE);
                    SharedPreferences.Editor editor = prefs.edit();
                    editor.putInt("clicks", clicks);
                    editor.apply();
                }
            });

Answer 1

Two options. You can declare your button as finale in this way:

final Button btnSave;

Or you can declare your button as an attribute of the class (Activity, Fragment or whatever) this way:

private Button btnSave;

Answer 2

Original:

if (clicks >= 5){
                    btnsave.setEnabled(false);
                }

Changed working code:

if (clicks >= 5){
                   ((Button)view).setEnabled(false)
                }
