Activity代码

public class RatingBarDemoActivity extends Activity {

    private RatingBar rb=null;

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        rb=(RatingBar)findViewById(R.id.ratingbar1);

        rb.setOnRatingBarChangeListener(new ClickRatingBar());

}

//设置监听器

    class ClickRatingBar implements RatingBar.OnRatingBarChangeListener{

 

       @Override

       public void onRatingChanged(RatingBar ratingBar, float rating,

              boolean fromUser) {

           // TODO Auto-generated method stub

           Toast.makeText(RatingBarDemoActivity.this, rating+"", Toast.LENGTH_LONG).show();

           

       }

    

    }

}
