How to get the selected item from ListView?

Question

in my Android app I have created a ListView component called myList, and filled it with objects of my own custom type:

class MyClass{

    private String di         


        

Answer 1

Using setOnItemClickListener is the correct answer, but if you have a keyboard you can change selection even with arrows (no click is performed), so, you need to implement also setOnItemSelectedListener :

myListView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> adapterView, View view, int position, long l) {
     MyObject tmp=(MyObject) adapterView.getItemAtPosition(position);
         }
            @Override
            public void onNothingSelected(AdapterView<?> adapterView) {
                // your stuff
            }
        });

Answer 2

In touch mode, there is no focus and no selection. Your UI should use a different type of widget, such as radio buttons, for selection.

The documentation on ListView about this is terrible, just one obscure mention on setSelection.

Answer 3

Though I am using kotlin, the following code answered your question. This return selected item:

val item = myListView.adapter.getItem(i).toString()

The following is the whole selecteditem Listener

myListView.setOnItemClickListener(object : OnItemClickListener {
       override fun onItemClick(parent: AdapterView<*>, view: View, i: Int,
                        id: Long) {
           val item = myListView.adapter.getItem(i).toString()

       }
    })

The code returns the item clicked by its index i as shown in the code
