Question

我正在编写一个非常简单的对话框片段，它显示3个选项并将选择返回到父片段。做出选择后，我希望对话框解除自己。下面是我写的onCreateDialogMethod，调用了CheckOutDialogFragment.this.dismiss（）。我也尝试过dismiss（）和其他一些方法。有什么建议？

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    activity = this.getActivity();
    Bundle args = getArguments();
    final String comment =  args.getString(CheckInOutFragment.COMMENT);
    AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(activity);
    dialogAdapter = new CheckOutDialogAdapter(this.getActivity());
    final Intent data = new Intent();

    myAlertDialog.setSingleChoiceItems(dialogAdapter, -1, new    DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialogInterface, int selection){
            ActivityModel.CheckOutType type = dialogAdapter.getActivityTypeForIndex(selection);
            data.putExtra(CheckInOutFragment.COMMENT, comment);
            data.putExtra(CHOICE, type);
            getTargetFragment().onActivityResult(getTargetRequestCode(), Activity.RESULT_OK, data);
            CheckOutDialogFragment.this.dismiss();
            //TODO: figure out why this won't dismiss
        }
    });

    return myAlertDialog.create();
}

Answer 1

而不是：

CheckOutDialogFragment.this.dismiss();

应该只是：

dismiss();

Answer 2

原来我的IDE需要重启，我的项目没有正确构建。 CheckOutDialogFragment.this.dismiss（）和dismiss（）都有效。

Android Dialog Fragment不会被解雇
