从另一个DialogFragment显示DialogFragment [英] Show DialogFragment from another DialogFragment

问题描述

我有一个DialogFragment，向用户显示选项列表，这些选项之一是删除"选项，当用户按下Delete选项时，我想显示另一个DialogFragment作为确认，不幸的是，该确认对话框不显示.

I have a DialogFragment that displays a list of options to the user, one of these options is "Delete" option, when the user presses the delete option I want to show another DialogFragment as a confirmation, unfortunately, the confirmation dialog doesn't show.

这是我的代码

第一个片段代码

public class ContactDialogOption extends SherlockDialogFragment {

    public static final String TAG = ContactDialogOption.class.getSimpleName();

    public ContactDialogOption() {
        super();
        // TODO Auto-generated constructor stub
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

        builder.setIcon(R.drawable.ic_launcher);
        builder.setTitle(R.string.options);

        builder.setItems(new String[] {

        getString(R.string.call), getString(R.string.send_message),
                getString(R.string.copy), getString(R.string.edit),
                getString(R.string.delete)

        }, new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                          if(which == 4) //delete
                          {
FragmentManager mgr = getActivity().getSupportFragmentManager();
    FragmentTransaction ft = mgr.beginTransaction();
        Fragment old = mgr.findFragmentByTag("SecondFragment");
        if (old != null) {
            ft.remove(old);
        }
        ft.addToBackStack(null);


fragment.show(ft, fragmentTag);
                          }
            }
        });

        return builder.create();
    }
}

推荐答案

我遇到了完全相同的问题，当您尝试从Fragment打开DialogFragment时，不会发生这种情况.

I got the exact same problem, this situation does not happen when you try to open a DialogFragment from a Fragment.

我发现的唯一解决方案是修改以下调用:

The only solution I found was to modify the following call:

fragment.show(ft, fragmentTag);

收件人:

fragment.show(getFragmentManager(), fragmentTag);

此解决方案的问题在于我们无法在FragmentTransition上工作.

The problem with this solution is that we cannot work on the FragmentTransition.

我不明白为什么行为与片段不同.

I don't understand why the behavior is different than with the fragments.
