我在片段中使用ExpandableListView,一切正常,直到我展开一个具有一些选定值的组(即橙色的颜色)。
请注意,红色矩形中的项目已切换位置。
以下是我的getGroupView()
和getChildView()
方法
@Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(context).inflate(R.layout.prayer_settings_list_item, parent, false);
}
((TextView) convertView.findViewById(R.id.setting_name_tv)).setText((String) getGroup(groupPosition));
return convertView;
}
@Override
public View getChildView(int groupPosition, final int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.azan_selection_item, parent, false);
MontserratRegTextView azanVoiceMakkahTv = (MontserratRegTextView) convertView.findViewById(R.id.azan_voice_tv);
final ImageView icPlayPause = (ImageView) convertView.findViewById(R.id.azan_play_ic);
icPlayPause.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
PrayerSettingsFragment.listener.onClick(childPosition, icPlayPause);
}
});
String azanVoice = (String) getChild(groupPosition, childPosition);
azanVoiceMakkahTv.setText(azanVoice);
return convertView;
}
答案 0 :(得分:0)
我有同样的问题我通过从getGroupView方法中删除此条件if (convertView == null)
来修复它
