我正在一个应用程序中处理ListView与ViewHolder合成的应用程序。在这个ViewHolder中，我有一个CheckBox。这是我的代码：
private class SettingsArrayAdapter extends ArrayAdapter<Object> {
Context context;
ArrayList<Object> values;
RowSettingsViewHolder vh = null;
BigRowSettingsViewHolder bvh = null;
@Override
public int getItemViewType(int position) {
if (values.get(position) instanceof RowContent) {
return SMALL_ROW_DESIGN;
} else
return BIG_ROW_DESIGN;
// return super.getItemViewType(position);
}
@Override
public int getViewTypeCount() {
return 2;
}
public SettingsArrayAdapter(Context context, ArrayList<Object> values) {
super(context, R.layout.row_settings, values);
this.context = context;
this.values = values;
}
// disable selection in title row
@Override
public boolean isEnabled(int position) {
return (position == 2 || position == 4 || position == 8 || position == 9 || position == 13) ? false : true;
}
public View getView(int position, View convertView, ViewGroup parent) {
vh = null;
bvh = null;
String sharedPrefKey;
// Log.i("VH", "vh tag: " +vh.toString());
int type = getItemViewType(position);
// big row excluded
if (type == SMALL_ROW_DESIGN) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.row_settings, parent, false);
vh = new RowSettingsViewHolder();
vh.titleTV = (TextView) convertView.findViewById(R.id.settings_row_title);
vh.subtitleTV = (TextView) convertView.findViewById(R.id.settings_row_subtitle);
vh.disclosureIV = (ImageView) convertView.findViewById(R.id.settings_disclosureIV);
vh.checkCB = (CheckBox) convertView.findViewById(R.id.settings_cB);
vh.separatorLine = (View) convertView.findViewById(R.id.settings_listView_separatorLine);
int id = Resources.getSystem().getIdentifier("btn_check_holo_light", "drawable", "android");
if (id != 0)
vh.checkCB.setButtonDrawable(id);
Typeface tf = Typeface.createFromAsset(getActivity().getAssets(), "fonts/Decima Light.otf");
vh.titleTV.setTypeface(tf);
convertView.setTag(vh);
Log.i("VH", "vh tag: " + vh.toString());
} else {
vh = (RowSettingsViewHolder) convertView.getTag();
vh.checkCB.setOnCheckedChangeListener(null);
}
vh.checkCB.setFocusable(false);
RowContent thisSetting = null;
thisSetting = (RowContent) values.get(position);
// set row values in view
vh.titleTV.setText(thisSetting.getTitle());
vh.disclosureIV.setImageDrawable(thisSetting.getDisclosureDrawable());
// subtitle
vh.subtitleTV.setText(thisSetting.getSubtitle());
String title = vh.titleTV.getText().toString();
String subtitle = vh.subtitleTV.getText().toString();
if (subtitle.equals("NOTIFICATIONS") || subtitle.equals("MUSIC") || subtitle.equals("EMAIL") || subtitle.equals("SYSTEM")) {
Typeface tfSubt = Typeface.createFromAsset(getActivity().getAssets(), "fonts/Decima Bold.otf");
vh.subtitleTV.setTypeface(tfSubt);
vh.separatorLine.setBackgroundColor(Color.BLACK);
} else {
Typeface tf = Typeface.createFromAsset(getActivity().getAssets(), "fonts/Decima Light.otf");
vh.subtitleTV.setTypeface(tf);
vh.separatorLine.setBackgroundColor(Color.LTGRAY);
}
// checkbox
if (!thisSetting.needsCheckBox()) {
vh.checkCB.setVisibility(View.INVISIBLE);
vh.checkCB.setOnClickListener(null);
} else {
vh.checkCB.setVisibility(View.VISIBLE);
if (title.equals(getResources().getString(R.string.Spotify))) {
vh.checkCB.setChecked(sharedPreferencesHandler_settings.isSpotifyActive());
sharedPrefKey = SharedPrefsHandler.spotifyKey;
vh.checkCB.setTag(sharedPrefKey);
} else if (title.equals(getResources().getString(R.string.Google_Play))) {
vh.checkCB.setChecked(sharedPreferencesHandler_settings.isGooglePlayerActive());
sharedPrefKey = SharedPrefsHandler.googlePlayerKey;
vh.checkCB.setTag(sharedPrefKey);
} else if (title.equals(getResources().getString(R.string.default_music_player))) {
vh.checkCB.setChecked(sharedPreferencesHandler_settings.isDefaultPlayerActive());
sharedPrefKey = SharedPrefsHandler.defaulPlayerKey;
vh.checkCB.setTag(sharedPrefKey);
} else if (title.equals(getResources().getString(R.string.default_mail))) {
vh.checkCB.setChecked(sharedPreferencesHandler_settings.isDefaultEmailAppActive());
sharedPrefKey = SharedPrefsHandler.defaultEmailKey;
vh.checkCB.setTag(sharedPrefKey);
} else if (title.equals(getResources().getString(R.string.Hotmail))) {
vh.checkCB.setChecked(sharedPreferencesHandler_settings.isHotmailActive());
sharedPrefKey = SharedPrefsHandler.hotmailKey;
vh.checkCB.setTag(sharedPrefKey);
} else if (title.equals(getResources().getString(R.string.Gmail))) {
vh.checkCB.setChecked(sharedPreferencesHandler_settings.isGmailActive());
sharedPrefKey = SharedPrefsHandler.gmailKey;
vh.checkCB.setTag(sharedPrefKey);
} else if (title.equals(getResources().getString(R.string.enable_disable_all_notif))) {
vh.checkCB.setChecked(sharedPreferencesHandler_settings.areAllNotifsActive());
sharedPrefKey = SharedPrefsHandler.allNotifsActiveKey;
vh.checkCB.setTag(sharedPrefKey);
}
vh.checkCB.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
// Log.i("TabSettingsActivity", "checked");
Log.i("VH-2", "vh tag: " + vh.toString());
sharedPreferencesHandler_settings.setSettingActive(SharedPrefsHandler.allNotifsActiveKey, vh.checkCB.isChecked());
Log.i("TabSettingsActivity", "checked: " + Boolean.toString(isChecked));
// Log.i("isChecked", vh.checkCB.getTag().toString());
Log.i("TabSettingsActivity", "vh tag: " + vh.checkCB.getTag().toString());
sharedPreferencesHandler_settings.setSettingActive(vh.checkCB.getTag().toString(), isChecked);
// Do something here.
Log.i("VH-ID", "vh tag: " + vh.toString());
}
});
}
}
// big row
else {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.row_settings_big, parent, false);
bvh = new BigRowSettingsViewHolder(convertView);
convertView.setTag(bvh);
}
else {
bvh = (BigRowSettingsViewHolder) convertView.getTag();
}
bvh.setRowData();
}
return convertView;
}
}
我正在做的事情存储在SharedPreferences ViewHolder项值中。当我把tic放在任何CheckBox中时，似乎一切正常，但如果我使用滚动，勾号消失，那么我一直在调查，我做了下一个：
我把这一行：
Log.i("VH-ID", "vh tag: " +vh.toString());
在创建ViewHolder时，我可以获取每个ViewHolder的ID，同时我在侦听器方法中添加了与上面相同的行：
vh.checkCB.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
// Log.i("TabSettingsActivity", "checked");
Log.i("VH-2", "vh tag: " + vh.toString());
sharedPreferencesHandler_settings.setSettingActive(SharedPrefsHandler.allNotifsActiveKey, vh.checkCB.isChecked());
Log.i("TabSettingsActivity", "checked: " + Boolean.toString(isChecked));
// Log.i("isChecked", vh.checkCB.getTag().toString());
Log.i("TabSettingsActivity", "vh tag: " + vh.checkCB.getTag().toString());
sharedPreferencesHandler_settings.setSettingActive(vh.checkCB.getTag().toString(), isChecked);
// Do something here.
Log.i("VH-ID", "vh tag: " + vh.toString());
}
});
问题是，例如，当应用程序启动时，我可以看到所有ViewHolder ID，但当我检查任何人时，我可以看到ID是如何不同的，所以它采用了不同的{{1}我检查过的，我不知道为什么要使用不同的ID（ViewHolder）。
我做了Sufian告诉我的更改，这是代码，即便如此，现在我得到ViewHolder
unfortunatly....}
我希望这有助于解决问题

答案 0 :(得分：1)
当我遇到类似问题时，我检查了我做了什么。我实际上只设置OnCheckedChangeListener一次（当创建行时，即inflater.inflate()）。我将行号设置为CheckBox的标记。
以下是我的代码：
if (convertView == null || convertView.getTag() == null) {
holder = new Holder();
//TODO set holder fields here
holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
int rowPosition = (Integer)buttonView.getTag();
getItem(rowPosition).setMarked(buttonView.isChecked());
}
});
convertView.setTag(holder);
}
else
holder = (Holder) convertView.getTag();
holder.checkBox.setTag(position);
holder.checkBox.setChecked(item.isChecked());
