Question

i want to show numbers in EditText one after one not a random numbers like that so what is the perfect code to do this step ?

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final Button add = (Button) findViewById(R.id.button1);
        final EditText edit = (EditText)findViewById(R.id.editText1);

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                random = random();
                edit.setText("text" + random); // want to show numbers one after one like 1,2,3,4,5 

            }

            public int random() {
                Random generator = new Random();

                int x = generator.nextInt(100);
                return x;
            }
        });
    }

这样做

 private int number=0;

 @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
              //  random = random();
                edit.setText("text" + number++); // want to show numbers one after one like 1,2,3,4,5 

            }
