带文字和图片的自定义列表视图搜索框

Question

大家好。我创建了一个包含图像，文本和搜索框的列表视图。 这是我的代码：java和布局。所以，我需要一些帮助。我不知道如何做我的搜索框开始工作。我需要一个代码。

我MainActivity.java

package android.codigos; 

import android.app.Activity; 
import android.codigos.objetos.ItemListView; 
import android.graphics.Color; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.AdapterView.OnItemClickListener; 

import android.widget.EditText; 
import android.widget.ListView; 
import android.widget.Toast; 
import java.util.ArrayList; 



public class MainActivity extends Activity implements OnItemClickListener { 

private ListView listView; 
private EditText ed; 
private AdapterListView adapterListView; 
private ArrayList<ItemListView> itens; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    //carrega o layout onde contem o ListView 
    setContentView(R.layout.main); 

    //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 
    itens = new ArrayList<ItemListView>(); 
    ItemListView item1 = new ItemListView("Bahia", R.drawable.bahia); 
    ItemListView item2 = new ItemListView("Minas Gerais", R.drawable.minasgerais); 
    ItemListView item3 = new ItemListView("Rio de Janeiro", R.drawable.riodejaneiro); 
    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(); 
} 

}

AdapterListView.java

package android.codigos; 

import android.codigos.objetos.ItemListView; 
import android.content.Context; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.ImageView; 
import android.widget.TextView; 
import java.util.ArrayList; 

/**

*/ 
public class AdapterListView extends BaseAdapter { 

private LayoutInflater mInflater; 
private ArrayList<ItemListView> itens; 

public AdapterListView(Context context, ArrayList<ItemListView> itens) { 
    //Itens que preencheram o listview 
    this.itens = itens; 
    //responsavel por pegar o Layout do item. 
    mInflater = LayoutInflater.from(context); 
} 

/** 
* Retorna a quantidade de itens 
* 
* @return 
*/ 
public int getCount() { 
    return itens.size(); 
} 

/** 
* Retorna o item de acordo com a posicao dele na tela. 
* 
* @param position 
* @return 
*/ 
public ItemListView getItem(int position) { 
    return itens.get(position); 
} 

/** 
* Sem implementação 
* 
* @param position 
* @return 
*/ 
public long getItemId(int position) { 
    return position; 
} 

public View getView(int position, View view, ViewGroup parent) { 
    //Pega o item de acordo com a posção. 
    ItemListView item = itens.get(position); 
    //infla o layout para podermos preencher os dados 
    view = mInflater.inflate(R.layout.item_list, null); 

    //atravez do layout pego pelo LayoutInflater, pegamos cada id relacionado 
    //ao item e definimos as informações. 
    ((TextView) view.findViewById(R.id.text)).setText(item.getTexto()); 
    ((ImageView) view.findViewById(R.id.imagemview)).setImageResource(item.getIconeRid()); 

    return view; 
} 

}

ItemListView.java

package android.codigos.objetos; 

/** 
* 
*/ 
public class ItemListView { 

private String texto; 
private int iconeRid; 

public ItemListView() { 
} 

public ItemListView(String texto, int iconeRid) { 
    this.texto = texto; 
    this.iconeRid = iconeRid; 
} 

public int getIconeRid() { 
    return iconeRid; 
} 

public void setIconeRid(int iconeRid) { 
    this.iconeRid = iconeRid; 
} 

public String getTexto() { 
    return texto; 
} 

public void setTexto(String texto) { 
    this.texto = texto; 
} 

}

main.xml中

Answer 1

一般的算法如下：

1. 从EditText上以文本。
2. 从ArrayList中删除与搜索查询不匹配的所有项目。
3. 刷新您的适配器与方法adapter.notifyDataSetChanged（）

如果你需要的源代码的例子，我可以将它。
