holder.edt_markedPrice.addTextChangedListener(new TextWatcher() { public void beforeTextChanged(CharSequence s, int start, int count, int after) { } public void onTextChanged(CharSequence s, int start, int before, int count) { Log.e("position::::", "position::::" + position); } public void afterTextChanged(Editable s) { } }); — Ankit Kamboj, Jan 18 '16 at 11:38
check this..i want to get only edit text position when user types in ontextchange listener method. — Ankit Kamboj, Jan 18 '16 at 11:38
if you want item position then why are you using textwatcher ? Use itemClickListener for getting the item position. — Surabhi Singh, Jan 18 '16 at 11:42
I want to get item position when user type something on edit text or Autocomplete textview. — Ankit Kamboj, Jan 18 '16 at 11:45
because i have to change edit text value and then to notify the activity for that particular position. Then i have to calculate the sum of total edit text values. — Ankit Kamboj, Jan 18 '16 at 11:47

autoCompleteTextView.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view, int position, long rowId) {
        String selection = (String)parent.getItemAtPosition(position);
        //TODO Do something with the selected text
    }
});

Not on item click, in on Textchange listener method. – Ankit Kamboj Jan 18 '16 at 11:41
implement textwatcher in custom adapter or in activity(if adapter data is assigned on oncreate method) – DIGITAL JEDI Jan 18 '16 at 11:46

This is how you can get position of Item you typed in AutoCompleteTextView. But you have to add the full name of item like "apple" or "apples" then this code will give you the position of that particular item. But its very expensive process if you have lots of items in your list.

public class Test extends AppCompatActivity {

private AutoCompleteTextView autoCompleteTextView;
private List<String> list;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_chintan_test);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    list = new ArrayList<>();
    list.add("Apple");
    list.add("Apples");
    list.add("Banana");
    list.add("Aunt");
    list.add("Orange");

    autoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView);
    autoCompleteTextView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, list));

    autoCompleteTextView.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) {
            for (String string : list)
                if (string.toLowerCase().equals(s.toString().toLowerCase())) {
                    int pos = list.indexOf(string);
                    Toast.makeText(Test.this, "" + pos, Toast.LENGTH_SHORT).show();
                }
        }

        @Override
        public void afterTextChanged(Editable s) {

        }

    });
}

}

Let me know if this code helps you.

Use textwatcher, implement it in activity class.

@Override
public void afterTextChanged(Editable arg0) {
 // TODO Auto-generated method stub

}

@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
 // TODO Auto-generated method stub

}

            long arg3) {
        Student selected = (Student) arg0.getAdapter().getItem(arg2);
        Toast.makeText(MainActivity.this,
                "Clicked " + arg2 + " name: " + selected.name,
                Toast.LENGTH_SHORT).show();
    }
});

you can use addTextChangedListener for this purpose

 yourAutoCompleteTextView.addTextChangedListener(new TextWatcher() {

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

}

@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {                

}

@Override
public void afterTextChanged(Editable s) {

} });
