I've the Custom CustomerAdapter
public class CustomerAdapter extends ArrayAdapter<Customer> {
private final String MY_DEBUG_TAG = "CustomerAdapter";
private ArrayList<Customer> items;
private int viewResourceId;
public CustomerAdapter(Context context, int viewResourceId, ArrayList<Customer> items) {
super(context, viewResourceId, items);
this.items = items;
this.viewResourceId = viewResourceId;
}
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(viewResourceId, null);
}
Customer customer = items.get(position);
if (customer != null) {
TextView customerNameLabel = (TextView) v.findViewById(R.id.customerNameLabel);
if (customerNameLabel != null) {
customerNameLabel.setText(String.valueOf(customer.getName()));
}
}
return v;
}
}
and customer_auto
layout
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/customerNameLabel"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:padding="10dp" android:textSize="16sp"
android:textColor="#000">
</TextView>
and on my public void onCreate
AutoCompleteTextView customerAutoComplete = (AutoCompleteTextView) findViewById(R.id.autocomplete_customer);
CustomerAdapter customerAdapter = new CustomerAdapter(this, R.layout.customer_auto, customerList);
customerAutoComplete.setAdapter(customerAdapter);
and Customer.java
public class Customer implements Parcelable {
private int id;
private String name = "";
public Customer() {
// TODO Auto-generated constructor stub
}
/**
* This will be used only by the MyCreator
*
* @param source
*/
public Customer(Parcel source) {
/*
* Reconstruct from the Parcel
*/
id = source.readInt();
name = source.readString();
}
public void setId(int id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
public int getId() {
return this.id;
}
public String getName() {
return this.name;
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(id);
dest.writeString(name);
}
public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
@Override
public Customer createFromParcel(Parcel source) {
return new Customer(source);
}
@Override
public Customer[] newArray(int size) {
return new Customer[size];
// TODO Auto-generated method stub
}
};
@Override
public String toString() {
return this.name;
}
}
But the auto suggest box does not filter correctly. for eg; if i type an
in the test box customers starting with br
are showing up!
I have to over-ride the getFilter() method of the Adapter
Here is the code which worked for me, thanks to sacoskun
public class CustomerAdapter extends ArrayAdapter<Customer> {
private final String MY_DEBUG_TAG = "CustomerAdapter";
private ArrayList<Customer> items;
private ArrayList<Customer> itemsAll;
private ArrayList<Customer> suggestions;
private int viewResourceId;
public CustomerAdapter(Context context, int viewResourceId, ArrayList<Customer> items) {
super(context, viewResourceId, items);
this.items = items;
this.itemsAll = (ArrayList<Customer>) items.clone();
this.suggestions = new ArrayList<Customer>();
this.viewResourceId = viewResourceId;
}
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(viewResourceId, null);
}
Customer customer = items.get(position);
if (customer != null) {
TextView customerNameLabel = (TextView) v.findViewById(R.id.customerNameLabel);
if (customerNameLabel != null) {
// Log.i(MY_DEBUG_TAG, "getView Customer Name:"+customer.getName());
customerNameLabel.setText(customer.getName());
}
}
return v;
}
@Override
public Filter getFilter() {
return nameFilter;
}
Filter nameFilter = new Filter() {
@Override
public String convertResultToString(Object resultValue) {
String str = ((Customer)(resultValue)).getName();
return str;
}
@Override
protected FilterResults performFiltering(CharSequence constraint) {
if(constraint != null) {
suggestions.clear();
for (Customer customer : itemsAll) {
if(customer.getName().toLowerCase().startsWith(constraint.toString().toLowerCase())){
suggestions.add(customer);
}
}
FilterResults filterResults = new FilterResults();
filterResults.values = suggestions;
filterResults.count = suggestions.size();
return filterResults;
} else {
return new FilterResults();
}
}
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
ArrayList<Customer> filteredList = (ArrayList<Customer>) results.values;
if(results != null && results.count > 0) {
clear();
for (Customer c : filteredList) {
add(c);
}
notifyDataSetChanged();
}
}
};
}
