ratingbar

问题 I tried to create a custom rating bar. I don't use style because I only use this once. So, I created a layer-list in the drawable folder (its name is custom_rating_bar.xml ): <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@android:id/background" android:drawable="@drawable/custom_icon_empty"/> <item android:id="@android:id/secondaryProgress" android:drawable="@drawable/custom_icon_empty"/> <item android:id="@android:id/progress" android:drawable="

问题 With Android SDK 1.1 r1 , is there any way to change the RatingBar widget class's star image with my own? Is this possible at all? If so, then how? Thanks. 回答1: The short answer is it looks like it's techincally possible. The easiest way would be to create your own RatingBar based on the RatingBar sourcecode (more elegant would be to extend the orignal RatingBar into your own). From there you would also need to create your own RatingBar style using the original RatingBar source xml as an

问题 In my Android app I've got a Fragment showing a RatingBar, which has a onRatingChanged listener that is not responding to ratingbar changes. So here's my code: rating_fragment.xml <android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/rating_fragment" android:layout_width="match_parent" android:layout_height="wrap_content"> <LinearLayout android:layout_width="match_parent" android:layout

However, most of the solutions to this revolve around changing the default graphic used in the raing bar, and not how to

It would always show up

问题 I have an android rating bar in my app, and it only displays int ratings. For example: float ratingValue = 1.5f; myRatingBar.setRating(ratingValue); and the ratingbar displays 2 full stars.
