みなさんこんにちは。画像、テキスト、検索ボックスを含むリストビューを作成しました。これは私のコードです: Java とレイアウト。だから、私はいくつかの助けが必要です。検索ボックスが機能し始める方法がわかりません。コードが必要です。
私の MainActivity.java

//Pega a referencia do ListView
listView = (ListView) findViewById(R.id.list);
ed = (EditText)findViewById(R.id.EditText01);
//Define o Listener quando alguem clicar no item.
listView.setOnItemClickListener(this);
createListView();
}
private void createListView() {
//Criamos nossa lista que preenchera o ListView

ItemListView item1 = new ItemListView("Bahia", R.drawable.bahia);

ItemListView item4 = new ItemListView("São Paulo", R.drawable.saopaulo);
itens.add(item1);
itens.add(item2);
itens.add(item3);
itens.add(item4);
//Cria o adapter
adapterListView = new AdapterListView(this, itens);
//Define o Adapter
listView.setAdapter(adapterListView);
//Cor quando a lista é selecionada para rolagem.
listView.setCacheColorHint(Color.TRANSPARENT);
}
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
//Pega o item que foi selecionado.
ItemListView item = adapterListView.getItem(arg2);
//Demostração
Toast.makeText(this, "Você Clicou em: " + item.getTexto(), Toast.LENGTH_LONG).show();
