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);
            }
        });
    }
