1. Solusi 1, Menggunakan filter bawaan dari Simple Adapter

public class ActivityShotList extends Activity {

    private String[] shotlistArray;
    private String[] shotDetailsListArray;
    private ListView listShots = null;
    ArrayAdapter<String> adapter;
    EditText inPutSearch;
    int dt;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        listShots = (ListView) findViewById(R.id.listViewShotsReport);
        shotlistArray = getResources().getStringArray(R.array.shotslist);
        shotDetailsListArray = getResources().getStringArray(
                R.array.shotsDetails);

        adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, android.R.id.text1,
                shotlistArray);

        listShots.setAdapter(adapter);

        inPutSearch = (EditText) findViewById(R.id.inputSearch);



        listShots.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {

                // Get the item that was clicked   [position] 
                Object itemName = listShots.getItemAtPosition(position);
                String keyword = itemName.toString();
                String info = shotDetailsListArray[position];


                //Toast.makeText(getApplicationContext(),"You have selected:  " + keyword, Toast.LENGTH_SHORT).show();
                //
                Intent i = new Intent(getBaseContext(),
                        ActivityShotDetails.class);
                i.putExtra("info", info);
                i.putExtra("name", keyword);
                startActivity(i);

        }
        });

        inPutSearch.addTextChangedListener(new TextWatcher() {

            @Override
            public void onTextChanged(CharSequence cs, int start, int before, int count) {
                ActivityShotList.this.adapter.getFilter().filter(cs);

            }

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

            }

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

            }
        });

    }
}

2. Membuat filter dengan adapter yang dikustomisasi


public class ListViewAdapter extends BaseAdapter {
 
// Declare Variables
Context mContext;
LayoutInflater inflater;
private List<WorldPopulation> worldpopulationlist = null;
private ArrayList<WorldPopulation> arraylist;
 
public ListViewAdapter(Context context, List<WorldPopulation> worldpopulationlist) {
mContext = context;
this.worldpopulationlist = worldpopulationlist;
inflater = LayoutInflater.from(mContext);
this.arraylist = new ArrayList<WorldPopulation>();
this.arraylist.addAll(worldpopulationlist);
}
 
public class ViewHolder {
TextView rank;
TextView country;
TextView population;
}
 
@Override
public int getCount() {
return worldpopulationlist.size();
}
 
@Override
public WorldPopulation getItem(int position) {
return worldpopulationlist.get(position);
}
 
@Override
public long getItemId(int position) {
return position;
}
 
public View getView(final int position, View view, ViewGroup parent) {
final ViewHolder holder;
if (view == null) {
holder = new ViewHolder();
view = inflater.inflate(R.layout.listview_item, null);
// Locate the TextViews in listview_item.xml
holder.rank = (TextView) view.findViewById(R.id.rank);
holder.country = (TextView) view.findViewById(R.id.country);
holder.population = (TextView) view.findViewById(R.id.population);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
// Set the results into TextViews
holder.rank.setText(worldpopulationlist.get(position).getRank());
holder.country.setText(worldpopulationlist.get(position).getCountry());
holder.population.setText(worldpopulationlist.get(position).getPopulation());
 
// Listen for ListView Item Click
view.setOnClickListener(new OnClickListener() {
 
@Override
public void onClick(View arg0) {
// Send single item click data to SingleItemView Class
Intent intent = new Intent(mContext, SingleItemView.class);
// Pass all data rank
intent.putExtra("rank",(worldpopulationlist.get(position).getRank()));
// Pass all data country
intent.putExtra("country",(worldpopulationlist.get(position).getCountry()));
// Pass all data population
intent.putExtra("population",(worldpopulationlist.get(position).getPopulation()));
// Pass all data flag
// Start SingleItemView Class
mContext.startActivity(intent);
}
});
 
return view;
}
 
// Filter Class
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
worldpopulationlist.clear();
if (charText.length() == 0) {
worldpopulationlist.addAll(arraylist);
}
else
{
for (WorldPopulation wp : arraylist)
{
if (wp.getCountry().toLowerCase(Locale.getDefault()).contains(charText))
{
worldpopulationlist.add(wp);
}
}
}
notifyDataSetChanged();
}
 
 
Memanggilnya sebagai berikut

// Capture Text in EditText
editsearch.addTextChangedListener(new TextWatcher() {
 
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
String text = editsearch.getText().toString().toLowerCase(Locale.getDefault());
adapter.filter(text);
}
 
@Override
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
 
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
});
