我似乎在抓住我的评级栏点击时出现问题。评级栏显示正常,并具有默认值。唯一的问题是我无法更改任何值或未启用。我尝试了很多不同的东西(例如在布局中启用,完全用java构建)。他们似乎没有任何影响。这是我最新的评级栏的化身。我必须做一些stooopid才能捕捉到点击。
Java代码:
RatingBar showRatingBar = (RatingBar) findViewById(R.id.showRatingBar);
showRatingBar.setEnabled(true);
showRatingBar.setClickable(true);
showRatingBar.setRating(0);
showRatingBar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener(){
@Override
public void onRatingChanged(RatingBar ratingBar, float rating,
boolean fromUser) {
System.out.println("showRating.buildRatingBar: " +rating);
ratingBar.setRating(rating);
}});
showRatingBar.refreshDrawableState();
布局:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
android:id="@+id/showQualityLabel"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:text="@string/show_rating_label"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#E6E6E6"
android:textSize="12sp" />
<RatingBar
android:id="@+id/showRatingBar"
style="?android:attr/ratingBarStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:max="5"
android:numStars="5"
android:rating="0"
android:stepSize="1"/>
</LinearLayout>
提前谢谢。

setOnClickListener()不起作用是RatingBar重写onTouchEvent()并且永远不让View处理它,所以从不调用View#performClick()(它会调用OnClickListener)。
派生自RatingBar并覆盖onTouchEvent()
ratingBar.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
float touchPositionX = event.getX();
float width = ratingBar.getWidth();
float starsf = (touchPositionX / width) * 5.0f;
int stars = (int)starsf + 1;
ratingBar.setRating(stars);
Toast.makeText(MainActivity.this, String.valueOf("test"), Toast.LENGTH_SHORT).show();
v.setPressed(false);
}
if (event.getAction() == MotionEvent.ACTION_DOWN) {
v.setPressed(true);
}
if (event.getAction() == MotionEvent.ACTION_CANCEL) {
v.setPressed(false);
}
return true;
}});
