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;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ViewUtils.inject(this);

        ratingbar_1.setOnRatingBarChangeListener(new OnRatingBarChangeListener() {
            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                if (fromUser) {
                    Toast.makeText(MainActivity.this, "你选择了：" + rating, Toast.LENGTH_LONG).show();
                }
            }
        });

    }

}
