底部床单在活动中没有膨胀

Question

我有这张底部表，我想在我的 DialogsActivity.java 中单击按钮时充气，但是每当我运行我的应用程序并单击按钮时，什么都没有发生。

这是应该膨胀底部工作表的代码。

DialogsActivity.java

    floatingButtonContainer = new FrameLayout(context);
            floatingButtonContainer.setVisibility(onlySelect && initialDialogsType != 10 || folderId != 0 ? View.GONE : View.VISIBLE);
            contentView.addView(floatingButtonContainer, LayoutHelper.createFrame((Build.VERSION.SDK_INT >= 21 ? 56 : 60) + 20, (Build.VERSION.SDK_INT >= 21 ? 56 : 60) + 20, (LocaleController.isRTL ? Gravity.LEFT : Gravity.RIGHT) | Gravity.BOTTOM, LocaleController.isRTL ? 4 : 0, 0, LocaleController.isRTL ? 0 : 4, 0));
            
     floatingButtonContainer.setOnClickListener(v -> {
                

                LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
                inflater.inflate(R.layout.fragment_bottom_sheet,null);
    
          
            });

这是 BottomSheetFrag.java

public class BottomSheetFrag extends BottomSheetDialogFragment {

    public BottomSheetFrag(){

    }


    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
        //return super.onCreateView(inflater, container, savedInstanceState);
        return inflater.inflate(R.layout.fragment_bottom_sheet, container, false);
    }
}

您的BottomSheetFrag代码看起来不错。

您不需要在活动中膨胀BottomSheetFrag ，而是应该为此目的使用Fragment Transaction 。

请如下更新您的DialogActivity代码。

    BottomSheetFrag bottomSheet = new BottomSheetFrag();

    FragmentManager fragmentManager = getSupportFragmentManager();

    fragmentManager.executePendingTransactions();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

    if (bottomSheet.isAdded()) {
        FragmentTransaction removeTransaction = fragmentManager.beginTransaction();
        removeTransaction.remove(bottomSheet);
        removeTransaction.commitNow();
    }

    fragmentTransaction.add(bottomSheet, "tag");
    fragmentTransaction.commitNow();
