Usage

for displaying

You are supposed to set tow properties, available and selectedCount. And available should be set as false.
you can use it in .xml

    <com.yeqingqing.qratingview.QRatingView
        android:id="@+id/main_qrv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:available="false" // if just for displaying ,there are should be false
        app:iconSize="40dp"
        app:selectedCount="3"
        app:totalCount="5" />

also it also will be work in java

   main_qrv2.available = false
   main_qrv2.selectedCount = 5
   

for rating

In this case, we need to set totalCount in .xml and add A selected Lisntener for result

    <com.yeqingqing.qratingview.QRatingView
        android:id="@+id/qrv_main3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:iconSize="40dp" 
        app:totalCount="5" />

     findViewById<QRatingView>(R.id.qrv_main3).setOnSelectedListener(object :
            QRatingView.OnSelectedListener 
            override fun onSelected(selectedCount: Int) 
                when (selectedCount) 
                //todo any reaction for rating
                    1 -> commence1.text = "很差"
                    2 -> commence1.text = "有待改进"
                    3 -> commence1.text = "还行"
                    4 -> commence1.text = "不错"
                    5 -> commence1.text = "非常可以"
                
            

        )
