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。
bottomSheetFragment.show(getSupportFragmentManager())
无法解析方法'show(?, java.lang.String)'无法解析 方法'getSupportFragmentManager()
我想在片段类中使用底页。
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);
}
}

根据documentation 为了在父片段和子片段之间传递数据,请执行以下操作: 启动
启动底部工作表:
button.setOnClickListener{
val sortRecipesBottomSheet = SortRecipesBottomSheet()
sortRecipesBottomSheet.show(childFragmentManager,sortRecipesBottomSheet.tag)
}
在同一个片段中编写此代码以接收来自底部工作表的结果
childFragmentManager.setFragmentResultListener(
"requestKey",
viewLifecycleOwner
) { key, bundle ->
val result = bundle.getString("bundleKey")
println("heeeeeeere: "+ result)
// Do something with the result
}
在您的底片片段中,为了将结果发回,请写下:
view.findViewById<MaterialButton>(R.id.sortByName).setOnClickListener {
parentFragmentManager.setFragmentResult(
"requestKey",
bundleOf("bundleKey" to SortType.ByName.key)
)
dismiss()
}
在 show()
方法中的父片段中,您正在发送 childFragmentManager
并且您正在使用 childFragmentManager
来收听结果,在底部表中您正在使用 parentFragmentManager
来设置结果供父片段读取。

是的,您可以像下面的代码一样在BottomSheetDialogFragment
中使用Fragment
,
BottomSheetDialogFragment bottomSheetFragment = new YourBottomSheetFragmentClass();
bottomSheetFragment.show(getFragmentManager(), bottomSheetFragment.getTag());
或者,如果您要将某些数据传递给BottomSheetDialogFragment
,请使用下面的代码,通过newInstance
,您可以发送和检索数据。
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
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();
}
还用YourBottomSheetFragmentClass
扩展了BottomSheetDialogFragment
