android个人学习笔记——RatingBar

 <RatingBar  android:id="@+id/ratingBar_1"android:layout_width="wrap_content"android:layout_height="wrap_content"android:numStars="5"android:rating="2.5"android:stepSize="1" />

在布局文件中使用RatingBar节点，
其中：android:numStars代表了最大有多少个星
android:rating 默认几个星是选中的
android:stepSize 当点击时一次前进的步数（可以为小数)
android:isIndicator=”true” 不可点击状态

public class MainActivity extends Activity {
    @ViewInject(R.id.ratingBar_1)private RatingBar ratingbar_1;@ViewInject(R.id.ratingBar_2)private RatingBar ratingBar_2;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ViewUtils.inject(this);ratingbar_1.setOnRatingBarChangeListener(new OnRatingBarChangeListener() {@Overridepublic void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {if (fromUser) {Toast.makeText(MainActivity.this, "你选择了：" + rating, Toast.LENGTH_LONG).show();}}});}}
