The init method takes the AttributeSet object as a parameter if the AttributeSet object null it will not do any things if attributes are provided to SaudSpinner then it will set padding 5 to all dimensions of the spinner. This method called through the constructors of SaudSpinner class. And also I have created the inti() method which takes the AtttributeSet object as a parameter. In the above image, I have created three constructors with different parameters for handling the attributes of our custom spinner attributes. It will add to your drawable folder.Ĭustomize the text view for the custom spinner It is done for our popup window layout which will display as a custom spinner in our MainActivity.īefore moving towards MainActivity, we should go to the drawable folder and right-click on it then go to the new option then select vector asset and find down arrow icon like the following image. So this is a short and easier way to bind String Array to ListView. Using the entries attribute, we don’t need to make an Adapter object in our Java coding and setting it to the ListView. This String Array I created earlier in our project’s Strings.xml file. In the ListView, I specified the entries attribute and the string array as a value of it. The id of the RelativeLayout is taken as “rl_custom_layout”.Īnd finally, a ListView is used in the RelativeLayout for displaying the items as scrollable and selectable. A RelativeLayout is taken as child layout of CardView with match_parent value of layout width and height. In the above image, I have taken CardView as a root view with 10 max elevations and layout width and layout height with match_parent value.
