我正在尝试创建一个DialogFragment,它显示一个带有自定义ListView的对话框.
@H_404_11@解决方法
public class MultiSelectDialogCustom extends DialogFragment {
ListView mLocationList;
private ArrayList<String> mOfficeListItems = new ArrayList<String>();
public static MultiSelectDialogCustom newInstance(int title) {
MultiSelectDialogCustom dialog = new MultiSelectDialogCustom();
Bundle args = new Bundle();
args.putInt("title",title);
dialog.setArguments(args);
return dialog;
}
@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
Collections.addAll(mOfficeListItems,getResources().getStringArray(R.array.offices));
View v = inflater.inflate(R.layout.fragment_choice_list,container,true);
mLocationList = (ListView)v.findViewById(R.id.location_criteria_list);
final FunctionListArrayAdapter adapter = new FunctionListArrayAdapter(
this,android.R.layout.simple_list_item_1,mOfficeListItems);
mLocationList.setAdapter(adapter);
getDialog().setTitle(getArguments().getInt("title"));
return v;
}
}
从片段中调用时：
MultiSelectDialogCustom dialogFrag = MultiSelectDialogCustom_.newInstance(R.string.dialog_title); dialogFrag.show(getActivity().getSupportFragmentManager(),null);
你应该重写onCreateDialog而不是使用onCreateView,它应该看起来像：
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Collections.addAll(mOfficeListItems,getResources().getStringArray(R.array.offices));
View v = getActivity().getLayoutInflater().inflate(R.layout.fragment_choice_list,null);
mLocationList = (ListView)v.findViewById(R.id.location_criteria_list);
final FunctionListArrayAdapter adapter = new FunctionListArrayAdapter(
this,mOfficeListItems);
mLocationList.setAdapter(adapter);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(getArguments().getInt("title")).setView(v);
return builder.create();
}
DialogFragment documentation page的引用描述了您要做的事情：
Implementations should override this class and implement
onCreateView(LayoutInflater,ViewGroup,Bundle)to supply the content of the dialog. Alternatively,they can overrideonCreateDialog(Bundle)to create an entirely custom dialog,such as anAlertDialog,with its own content.
