问题描述
我正在尝试在点击侦听器中使用底部表单，但此行出现错误.
I am trying to use the bottom sheet in a click listener but I am getting an error on this line.
bottomSheetFragment.show(getSupportFragmentManager())
无法解析方法'show(?, java.lang.String)'无法解析方法'getSupportFragmentManager()
Cannot resolve method 'show(?, java.lang.String)' Cannot resolve method 'getSupportFragmentManager()
我想在片段类中使用底页.
I want to use the bottom sheet in a fragment class.
SubCategoryDetailFragment.java
public class SubCategoryDetailFragment extends Fragment {
TextView txtv_sort;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view= inflater.inflate(R.layout.fragment_sub_category_detail, container, false);
toolbar = ((MainActivity) getActivity()).findViewById(R.id.toolbar);
toggle = ((MainActivity) getActivity()).getToggle();
shimmerContainer = view.findViewById(R.id.shimmer_view_container);
recyclerView_subcatDetail = view.findViewById(R.id.recycler_view_subCategoryDetail);
txtv_sort = view.findViewById(R.id.txtv_sort);
toggle.setDrawerIndicatorEnabled(false);
toggle.setHomeAsUpIndicator(R.drawable.back);
toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getActivity().onBackPressed();
}
});
txtv_sort.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
BottomSheetFragment bottomSheetFragment = new BottomSheetFragment();
bottomSheetFragment.show(getSupportFragmentManager(), bottomSheetFragment.getTag());
}
});
return view;
}
}
BottomSheetFragment.java
public class BottomSheetFragment extends Fragment {
public BottomSheetFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_bottom_sheet, container, false);
}
}

推荐答案
是的，您可以像下面的代码一样，在 Fragment 中使用 BottomSheetDialogFragment
Yes, you can use BottomSheetDialogFragment in Fragment simply like below code,
BottomSheetDialogFragment bottomSheetFragment = new YourBottomSheetFragmentClass();
bottomSheetFragment.show(getFragmentManager(), bottomSheetFragment.getTag());
或者，如果您要将某些数据传递给 BottomSheetDialogFragment ，请使用以下代码，并通过 newInstance 发送和检索数据.
Or if you want to pass some data to BottomSheetDialogFragment use below code, with newInstance you can send and retrieve data.
在您的片段类中:
BottomSheetDialogFragment myBottomSheet = YourBottomSheetFragmentClass.newInstance(SendString);
myBottomSheet.show(getFragmentManager(),myBottomSheet.getTag());
在您的BottomSheetFragment类中，添加以下行
In your BottomSheetFragment class, add below line
static YourBottomSheetFragmentClass newInstance(String retrieveString) {
YourBottomSheetFragmentClass f = new YourBottomSheetFragmentClass();
Bundle args = new Bundle();
args.putString("getString", retrieveString);
f.setArguments(args);
return f;
return new f();
}
还通过 BottomSheetDialogFragment
