Android Kotlin Dynamic RatingBar - setting number of stars

Time:04-12

I am trying to dynamically through Kotlin add a list of products with ratingbars for their ratings. I was able to add the ratingbars; however, the rating bars show 7 stars. I want 5 stars. I tried using *.numStars = 5 but I still get 7 stars as shown in the pic below for Popcorn.

    fun populateUIWithRatingInfo() {

    for (orderItem in orderItemsList) {
        val dynamicTextView = TextView(requireContext())
        dynamicTextView.text = orderItem.title
        binding.productRatingList.addView(dynamicTextView)

        val dynamicRatingBar = RatingBar(requireContext())
        dynamicRatingBar.numStars= 5
        binding.productRatingList.addView(dynamicRatingBar)
    }

}

Answer: The answer marked with the check mark is correct below. Since it doesn't describe how to do that dynamically, I will post a snippet of code that shows how to set width to wrap-content of the rating bar.

dynamicRatingBar.layoutParams = LinearLayout.LayoutParams(
            ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT
        )

CodePudding user response:

According to the android documentation, you need to set the layout_width property to wrap_content

public void setNumStars (int numStars): Sets the number of stars to show. In order for these to be shown properly, it is recommended the layout width of this widget be wrap content.
