私はたくさん検索しましたが、解決策はありません。imageview と textview を持つカスタム arrayadapter を設定しています。テキストを追加したい場所に編集テキストを保持し、これらの特定のテキストでフィルター処理されたリストを取得したいのですが、文字列型配列アダプターを使用すると、これはうまく機能しますが、カスタムアダプターでは機能しません。私のコードは次のとおりです。
public class CurrenciesFrom extends Activity implements OnItemClickListener {
ListView lvCurrencies;
String[] countryCode = { "BDT Bangladesh","BBF bafa" ,"USD America", "UMK Umaka","KRW Korea",
"INR India" };
int[] flag = { R.drawable.bdt, R.drawable.usd, R.drawable.aud,
R.drawable.ic_launcher ,R.drawable.usd, R.drawable.aud};
ArrayAdapter<Currency> adapter;
List<Currency> l;
EditText etsearch;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.currencies);
initializer();
lvCurrencies.setAdapter(adapter);
lvCurrencies.setOnItemClickListener(this);
etsearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
@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
CurrenciesFrom.this.adapter.getFilter().filter(s.toString());
}
});
}
private List<Currency> getModel() {
List<Currency> list = new ArrayList<Currency>();
for (int i = 0; i < countryCode.length; i++) {
list.add(get(countryCode[i], flag[i]));
}
list.get(1).setSelected(true); // select one item by default
return list;
}
private Currency get(String s, int place) {
return new Currency(s, place);
}
private void initializer() {
lvCurrencies = (ListView) findViewById(R.id.lvCurrencies);
etsearch=(EditText)findViewById(R.id.etSearch);
lvCurrencies.setTextFilterEnabled(true);
// countryCode = getResources().getStringArray(R.array.Currencies);
l = getModel();
Collections.sort(l, new Comparator<Currency>() {
@Override
public int compare(Currency c1, Currency c2) {
return c1.getName().compareToIgnoreCase(c2.getName());
}
});
adapter = new Customarrayadapter(this, l);
}
私のカスタムアダプタークラスは次のとおりです。
package com.powergroupbd.yahoo;
import java.util.List;
import android.app.Activity;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.ImageView;
import android.widget.TextView;
public class Customarrayadapter extends ArrayAdapter<Currency> {
private final List<Currency> list;
private final Activity context;
public Customarrayadapter(Activity context, List<Currency> list) {
super(context, R.layout.showlist, list);
this.context = context;
this.list = list;
}
static class ViewHolder {
protected TextView text;
protected ImageView sub;
protected CheckBox checkbox;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = null;
if (convertView == null) {
LayoutInflater inflator = context.getLayoutInflater();
view = inflator.inflate(R.layout.showlist, null);
final ViewHolder viewHolder = new ViewHolder();
viewHolder.text = (TextView) view.findViewById(R.id.label);
viewHolder.text.setTextColor(Color.WHITE);
viewHolder.sub = (ImageView) view.findViewById(R.id.sub);
viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check);
viewHolder.checkbox
.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
Currency element = (Currency) viewHolder.checkbox.getTag();
element.setSelected(buttonView.isChecked());
System.out.println("Checked : " + element.getName());
}
});
view.setTag(viewHolder);
viewHolder.checkbox.setTag(list.get(position));
} else {
view = convertView;
((ViewHolder) view.getTag()).checkbox.setTag(list.get(position));
}
ViewHolder holder = (ViewHolder) view.getTag();
holder.text.setText(list.get(position).getName());
holder.sub.setImageResource(list.get(position).getPlace());
holder.checkbox.setChecked(list.get(position).isSelected());
return view;
}
}
私を助けてください :(
