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();
}
}
});

}

}
