android学习笔记之RatingBar

使用RatingBar的步骤

1、在布局文件当中声明RatingBar

<RatingBar android:id="@+id/ratingBarId"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:numStars="5"

android:stepSize="1.0"/>

2、定义一个OnRatingBarChangeListener

private class RatingBarListener implements RatingBar.OnRatingBarChangeListener{

@Override

public void onRatingChanged(RatingBarratingBar, float rating,

boolean fromUser) {

System.out.println("rating-->" + rating);

}

}

3、设置监听器

RatingBar ratingBar = (RatingBar)findViewById(R.id.ratingBarId);

ratingBar.setOnRatingBarChangeListener(new RatingBarListener());
