安卓天天练练（十三）星星评分

这玩意用html做可麻烦了

<RatingBar
        android:id="@+id/ratingBar1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true" />

 java中用法和seekbar差不多

import android.widget.RatingBar;

import android.widget.RatingBar.OnRatingBarChangeListener;

final RatingBar rb = (RatingBar)findViewById(R.id.ratingBar1);
        rb.setOnRatingBarChangeListener(new OnRatingBarChangeListener() {
            
            @Override
            public void onRatingChanged(RatingBar rb, float rating,
                    boolean fromUser) {
                //float rate = rb.getRating();
                //同步刷新progressBar的话，pb.setProgress((int) (rate/5*100));
                //上面这行，先除以5*100，与先除以100*5是不同的
            }
        });
