Question

I have a EditText , a textView and a button,

I need to set my textView with the value of my EditText when a button is touched,
but I have a variable not being recognized [sorry noob on android here]

public class XynthaCalcTestActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //buttons
        benefixPaButtonPressed(); 
        benefixAdultButtonPressed();
        xynthaButtonPressed(); 
        calculateButtonPressed();

        //textField == EditText
        final EditText et;
        et = (EditText)findViewById(R.id.editText1);
    }

    public void calculateButtonPressed() {
        // TODO Auto-generated method stub
        Button button = (Button) findViewById(R.id.result);

        button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {

                Log.d("myTag",  "result biatch");

                String text=et.getText().toString();

                Toast msg = Toast.makeText(getBaseContext(),text, Toast.LENGTH_LONG);
                 msg.show();

            }

        });

    }
}

so on the line with String text=et.getText().toString();
I have the error et cannot be resolved

So …
how to declare my et Edit text so the button Class can see it?

thanks a lot!

Make et a field instead, having the final modifier makes no sense to me there.

public class XynthaCalcTestActivity extends Activity {

    private EditText et;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //buttons
        benefixPaButtonPressed(); 
        benefixAdultButtonPressed();
        xynthaButtonPressed(); 
        calculateButtonPressed();

        //textField == EditText
        et = (EditText)findViewById(R.id.editText1);
    }

    public void calculateButtonPressed() {
        // TODO Auto-generated method stub
        Button button = (Button) findViewById(R.id.result);

        button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {

                Log.d("myTag",  "result biatch");

                String text=et.getText().toString();

                Toast msg = Toast.makeText(getBaseContext(),text, Toast.LENGTH_LONG);
                 msg.show();

            }

        });

    }
}
