    copied!<p>I have a problem in making suggestion in <code>AutoCompleteTextView</code> in this pattern [action actionFromContact] (these are 2 adapter) ex call michael (where "call" comes from action adapter , "michael" from actionFromContact adapter these following code does first it set adapter in <code>AutoCompleteTextView</code> to item and when text changes to call it reset to contact db from name so its like call michael , <strong>Problem</strong> item array is too big so I can't use replace thing , second replacing remove the first entry when second entry i.e name is been selected from drop down menu as its been replaced by space </p> <pre><code> private AutoCompleteTextView mEditText; private TextWatcher mTextWatcher; private ContactPickerAdapter contactPickerAdapter; String item[] = { "Call", "Call back"}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mEditText = (WithSomeOneAutoCompleteTextView) findViewById(R.id.editTextTest); contactPickerAdapter = new ContactPickerAdapter(this, android.R.layout.simple_dropdown_item_1line, ContactQuery.getContacts(this, false)); mEditText.setAdapter(new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_dropdown_item_1line, item)); mTextWatcher = 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) { String t = s.toString().replace("call ","); contactPickerAdapter.getFilter().filter(t); if (s.toString().equalsIgnoreCase("call ")) { Toast.makeText(MainActivity.this, "CALL", Toast.LENGTH_SHORT).show(); mEditText.setAdapter(contactPickerAdapter); } if (s.toString().equalsIgnoreCase("Call back")) { // t.replace("call back ", ""); // System.out.println("t is: " + t); // contactPickerAdapter.getFilter().filter(t); Toast.makeText(MainActivity.this, "Launch", Toast.LENGTH_SHORT).show(); } } }; } </code></pre> <p>This is ContactPickerAdapter</p> <pre><code>public class ContactPickerAdapter extends ArrayAdapter&lt;Contact&gt; implements Filterable { private ArrayList&lt;Contact&gt; contactList, cloneContactList; private LayoutInflater layoutInflater; private Context mContext; public ContactPickerAdapter(Context context, int textViewResourceId, ArrayList&lt;Contact&gt; contactList) { super(context, textViewResourceId); this.contactList = contactList; this.cloneContactList = (ArrayList&lt;Contact&gt;) this.contactList.clone(); layoutInflater = (LayoutInflater) context .getSystemService(Activity.LAYOUT_INFLATER_SERVICE); } @Override public int getCount() { return contactList.size(); } @Override public Contact getItem(int position) { return contactList.get(position); } @Override public View getView(int position, View convertView, ViewGroup parent) { Holder holder; if (convertView == null) { convertView = layoutInflater.inflate( R.layout.withsomeone_contact_list_item, null); holder = new Holder(); holder.name = (TextView) convertView.findViewById(R.id.name); holder.phone = (TextView) convertView.findViewById(R.id.phone); convertView.setTag(holder); } else { holder = (Holder) convertView.getTag(); } Contact contact = getItem(position); holder.name.setText(contact.contactName); holder.phone.setText(contact.num); return convertView; } @Override public Filter getFilter() { Filter contactFilter = new Filter() { @SuppressWarnings("unchecked") @Override protected void publishResults(CharSequence constraint, FilterResults results) { if (results.values != null) { contactList = (ArrayList&lt;Contact&gt;) results.values; notifyDataSetChanged(); } } @Override protected FilterResults performFiltering(CharSequence constraint) { // CharSequence t = ""; System.out.println("contraints is equal: " + constraint); // if (constraint.toString().contains("call ")) { // // constraint = ""; // System.out.println("contraints now: " // + constraint.toString().replace("call ", "")); // t = constraint.toString().replace("call ", ""); // } // } else if // (constraint.toString().equalsIgnoreCase("call back ")) { // // constraint = ""; // System.out.println("contraints now: " + constraint); // t = constraint.toString().replace("call back ", ""); // // } // System.out.println("clone is equal: " + t); String sortValue = constraint == null ?
