android - 在 Fragment 中创建 AlarmDialog

Question

所以我在 fragment 中创建对话框时遇到错误

代码如下:

     public Dialog onCreateDialog(Bundle savedInstanceState) {
        int title = getArguments().getInt("title");

        return new AlertDialog.Builder(getActivity())
                .setIcon(R.drawable.logo)
                .setTitle(R.string.groupDetails_rename)
                .setPositiveButton(R.string.ok,
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int whichButton) {
                                ((GroupDetailsFragment)  getSupportFragmentManager())
                                        .doPositiveClick();
                            }
                        }).create();
    }

我在 ((GroupDetailsFragment) getSupportFragmentManager()) 上有错误我应该写什么来代替 getSupportFragmentManager() ？

Answer 1

GroupDetailsFragment f = (GroupDetailsFragment) getSupportFragmentManager().findFragmentByTag("tag");

f.doPositiveClick();

“标签”将在您调用“show()”时传递

getSupportFragmentManager->v4getFragmentManager->native
