次の基本アダプタカスタムクラスがあり、リストビューとアイテムを作成しています。しかし、リセットボタンをクリックしたときにリストからすべてのアイテムを削除したい。私のコード：
public class Scores extends Activity implements OnClickListener {
public static final String MY_PREFS_NAME = "PrefName";
SharedPreferences pref;
static String[] tempTime = new String[10];
static String[] tempScore = new String[10];
private static class EfficientAdapter extends BaseAdapter {
private LayoutInflater mInflater;
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return tempTime.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(
R.layout.mathmatch_score_format, null);
holder = new ViewHolder();
holder.text1 = (TextView) convertView
.findViewById(R.id.time_text);
holder.text2 = (TextView) convertView
.findViewById(R.id.score_text);
/*final ImageView deleteButton = (ImageView)
convertView.findViewById(R.id.score_reset);
deleteButton.setOnClickListener(this);*/
convertView.setTag(holder);
//deleteButton.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.text1.setText(tempTime[position]);
holder.text2.setText(tempScore[position]);
return convertView;
}
static class ViewHolder {
TextView text1;
TextView text2;
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mathmatch_score);
setUpViews();
pref = getSharedPreferences(MY_PREFS_NAME, 0);
strTime = pref.getString("high_score_times", "");
intScore = pref.getString("high_score_values", "");
tempTime = strTime.split(",");
tempScore = intScore.split(",");
Comparator<String> comparator = new CustomArrayComparator<String, String>(tempScore, tempTime);
Arrays.sort(tempTime, comparator);
Arrays.sort(tempScore, Collections.reverseOrder());
lv.setAdapter(new EfficientAdapter(this));
}
private void setUpViews() {
lv = (ListView) findViewById(R.id.list);
reset = (ImageView) findViewById(R.id.score_reset);
reset.setOnClickListener(this);
}
@Override
protected void onPause() {
super.onPause();
pref = getSharedPreferences(MY_PREFS_NAME, 0);
SharedPreferences.Editor edit = pref.edit();
edit.putString("high_score_times", strTime);
edit.putString("high_score_values", intScore);
edit.commit();
}
@Override
protected void onStop() {
super.onStop();
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.score_reset:
AlertDialog.Builder alertbox = new AlertDialog.Builder(this);
alertbox.setTitle("Reset");
alertbox.setMessage("Are you sure all time ans score are reset?");
alertbox.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
pref = getSharedPreferences(MY_PREFS_NAME, 0);
SharedPreferences.Editor edit = pref.edit();
/*edit.remove("high_score_times");
edit.remove("high_score_values");*/
/*edit.remove(intScore);
edit.remove(strTime);
*/
//edit.clear();
edit.remove(MY_PREFS_NAME);
edit.commit();
}
});
alertbox.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
Toast.makeText(getApplicationContext(), "'No' button clicked", Toast.LENGTH_SHORT).show();
}
});
alertbox.show();
break;
default:
break;
}}}
リセットボタンがリストに含まれていません。上記のコードのyesボタンクリックイベントでこれを試しましたが、更新を取得できませんでした。じゃあ何をすればいいの？前もって感謝します。
