Generating random number stops application

Question

I am trying to generate a random number on clicking the Button and print the value in EditText

I made it with this code

public class Board_Play1 extends Activity {

int d;
Random random = new Random();
@Override
protected void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.board_play1);

    Button button = (Button) findViewById(R.id.button1);
    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            d=random.nextInt(6)+1;
            EditText diceno = (EditText) findViewById(R.id.editText1);
            diceno.setText(d);

        }
    }); 

}

But on running application after clicking the button it pops up an error saying Unfortunately, your app has stopped . Cant understand why it is so. Can anyone explain what the mistake is?

Answer 1

You need to call the setText method that accepts a CharSequence as argument.

Currently you're calling setText(int resid) which will try to find the correct resource with the id specified, so I guess your program is throwing a ResourceNotFoundException .

So do:

diceno.setText(String.valueOf(d));

This will convert your int to String .

Also move the EditText diceno = (EditText) findViewById(R.id.editText1); before the onClick method. There is no need to retrieve it on each onClick event, just once suffice.

Finally in future, don't forget to post the stacktrace with your question.
