Android BottomSheetDialog 布局有按钮，onclick 导航到 Activity

Question

我有我的 Activity 调用的 BottomSheetDialog 布局 xml 文件。 BottomSheetDialog 有 2 个按钮。单击 BottomSheetDialog 内的按钮，它应该将我带到另一个 Activity。

使用这个

  public class CustomBottomSheetDialogFragment extends BottomSheetDialogFragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.content_dialog_bottom_sheet, container, false);
        Button btn1 = (Button)v.findViewById(R.id.btn1);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivity(new Intent(getActivity(),YourActivity.class));
            }
        });
        return v;
    }
 }

然后在您的 Activity 中调用这个 bottomSheet

new CustomBottomSheetDialogFragment().show(getSupportFragmentManager(), "Dialog");
