如何在android中以片段形式填充自定义列表？
我有一个片段，我想在其中创建一个自定义列表视图，但当我将参数发送到适配器时，它给了我一个错误 这是我的代码片段如何在android中以片段形式填充自定义列表？,android,android-fragments,android-studio,Android,Android Fragments,Android Studio,我有一个片段，我想在其中创建一个自定义列表视图，但当我将参数发送到适配器时，它给了我一个错误 这是我的代码片段 @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.fragment_list, container, false); TextVi

首先在片段中创建一个新方法并像膨胀一样膨胀
LayoutInflater inflater = (LayoutInflater) mActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View inflatedView2 = inflater.inflate(R.layout.activity_table_on_off_data, null);
create a new layout with listview and call it here
TableReport1 = (ListView) inflatedView2.findViewById(R.id.dataonofflister);
tableReportofOnOffData = new TableReportofOnOffData(mActivity.getApplicationContext(), listData);
TableReport1.setAdapter(null);
TableReport1.setAdapter(tableReportofOnOffData);
lvNullPointerExceptionListViewidListViewfragment\u列表中lv = (ListView) v.findViewById(R.id.listView);
错误消息是什么？指向代码以查看消息并共享它。好吧，当运行我的应用程序it show时，我对android太陌生了。。。不幸的是，我停了下来，没关系。但是你应该
Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
TableDisplayconditionView(date,getapplicationcontext());
}
create a new method outside of createview with parameters,
private void TableDisplayEventData(String date, Context context) {
LayoutInflater inflater = (LayoutInflater) mActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View inflatedView2 = inflater.inflate(R.layout.activity_event_details_data, null);
Gallery.removeAllViews();
Gallery.addView(inflatedView2);
TableReport2 = (ListView) inflatedView2.findViewById(R.id.dataonofflister);
tableReportofOnOffData = new TableReportofOnOffData(mActivity.getApplicationContext(), listData);
TableReport1.setAdapter(null);
TableReport1.setAdapter(tableReportofOnOffData);
}
The adapter looks like,
class TableReportofOnOffData extends BaseAdapter {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
view = lInflater.inflate(R.layout.activity_table_on_off_data_text, parent, false);
}
ListerOnOffData p = getProduct(position);
ListerOnOffData p2 = getProduct(position + 1);
((TextView) view.findViewById(R.id.date)).setText(p.getDate());
((TextView) view.findViewById(R.id.duration)).setText(p.getDuration());
((TextView) view.findViewById(R.id.powerfail)).setText(p.getPowerFail());
((TextView) view.findViewById(R.id.kwh)).setText(p.getKwh());
return view;
}
}
lv = (ListView) v.findViewById(R.id.listView);
