Question

I have the following code, which should change the value of an EditText field when the button is clicked…

public class ConvertActivity extends Activity {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        final Button b1 = (Button) findViewById(R.id.b1);
        b1.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                b1.setEnabled(true);

                EditText editText2 = (EditText)findViewById(R.id.editText2);
                String editTextStr2 = editText2.getText().toString();

                editText2.setText("empty");
    }
        });
    }
}

However, when I click the button, the text doesn’t change. Is there something wrong with my code?

Answer 1

comment out the line

editText2.setText(m.getND());

and see if it set editText2 to “empty” – my guess is m.getND() is returning null
