How to get The Spinner selected item position.? about betterspinner

[douglasjunior]

I dont know your need, but this library is a "Fake-spinner".

This library implement a EditText with AutoComplete. It looks like a spinner, works as spinner, but it's not a spinner.

Your items are strings. To know who is selected, simply retrieve the text that appears on the spinner, using the getText()

Then reneame this library to FakeSpinner and not betterSpinner

So, u r saying that this library is useless for my need. ?

Please, check #21. And to understand check #38.

You can get the item position using below listener:
material_spinner.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@OverRide
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {

        }
    });

@harshithagb be careful. This approach have a problem. If the item is selected programmatically, this event is not called.

Just add the listener of TextView.addTextChangedListener(new TextWatch(){...}) in the Constructer of your own Spinner which extends BetterSpinner/MaterialBetterSpinner, and in the callback method of void afterTextChanged(Editable s) you can get the position by mData.indexOf(getText()) and custom an callback function which involves the parm of "position". The sample code's as below:

public class CustomSpinner extends MaterialBetterSpinner {
    private OnItemSelectedListener l;
    private List<String> mData;
    public CustomSpinner(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        this.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
            }

            @Override
            public void afterTextChanged(Editable s) {
                if (l != null && mData != null) {
                    l.onItemSelected(mData.indexOf(getText().toString()));
                }
            }
        });
    }

    public interface OnItemSelectedListener {
        void onItemSelected(int position);
    }

    public void setOnItemSelectedListener(OnItemSelectedListener l) {
        this.l = l;
    }

    /**attach data*/
    public void attachDataSource(List<String> data) {
        this.mData = data;
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(getContext(), R.layout.item_spinner_data, data);
        adapter.setDropDownViewResource(R.layout.item_spinner_data);
        this.setAdapter(adapter);
    }
}
