There are specific scenario when we need to fill the android spinner from array list to dynamic fill the spinner data.

//sppinnder data create arrary listArrayListarrayList = new ArrayList<>(); arrayList.add("yoo"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); arrayList.add("bye bye"); spinner = findViewById(R.id.spinner); //create array adapter and provide arrary list to itArrayAdapter arrayAdapter = new ArrayAdapter (this,android.R.layout.simple_spinner_item,arrayList); arrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(arrayAdapter);

The article demonstrates a straightforward way to populate an Android Spinner dynamically using an ArrayList. The example first creates the list of values and then connects those values to the Spinner through an ArrayAdapter, which is a practical approach when Spinner data needs to be generated programmatically.
ReplyDeleteThe use of setDropDownViewResource() is also useful because it defines how the items should appear when the Spinner is expanded. Developers working with Android UI components can explore similar mobile application concepts through React Native Course, particularly when learning how dynamic interface elements are handled in mobile applications.
This example provides a simple foundation for building forms and interactive Android interfaces where selectable data may change dynamically. Such UI concepts can be applied in practical student applications and explored further through Android Projects for Final Year.
