初识RatingBar

RatingBar，SeekBar和ProgressBar的子类

 <RatingBar
             android:id="@+id/ratingBar2"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:numStars="6"
             android:rating="1.5"
             android:stepSize="0.5" />

RatingBar事件处理

 public void showRatingBar() {

         ratingBar = (RatingBar) findViewById(R.id.ratingBar1);
         ratingBar.setOnRatingBarChangeListener(new OnRatingBarChangeListener() {

             @Override
             public void onRatingChanged(RatingBar ratingBar, float rating,
                     boolean fromUser) {
                 // TODO Auto-generated method stub
                 Log.i(TAG, "rating is " + rating);
             }
         });
     }
