Question

我在AlertDialog中使用Dagger，就像下面这样：

@Module(includes = {
        WorkTableFragmentModule.WorkTableAPIViewAbstractModule.class,
        RemoteAPIDataModule.class
})
public class WorkTableFragmentModule {
  ...Some code...
      @Provides
    final AlertDialog.Builder alertDialogAccess(WorkTableFragment workTableFragment) {
        return new AlertDialog.Builder(Objects.requireNonNull(workTableFragment.getActivity()));
    }
    @Provides
    LayoutInflater layoutInflater(WorkTableFragment workTableFragment) {
        return Objects.requireNonNull(workTableFragment.getActivity()).getLayoutInflater();
    }
    @Provides
    View viewDialogAccess(LayoutInflater layoutInflater) {
        final ViewGroup nullParent = null;
        return layoutInflater.inflate(R.layout.dialog_access_share, nullParent);
    }
}

在Fragment中就像下面这样：

public class WorkTableFragment extends DaggerFragment{
@Inject
AlertDialog.Builder alertDialogAccess;
@Inject
View accessAlertDialogView;
@Inject
LayoutInflater inflater;

    private void accessAlertDialog() {
        if (getActivity() != null && isAdded()) {
            alertDialogAccess.setCancelable(false);
            new DialogViewHolderAcceptShare(accessAlertDialogView);
            alertDialogAccess.setView(accessAlertDialogView);
            dismissAccessDialog = alertDialogAccess.show();
        }
    }
}

但是让我听到以下错误：

Caused by: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

解决了我的以下问题：

private void accessAlertDialog() {
    if (getActivity() != null && isAdded()) {
        if (dismissAccessDialog == null) {
            alertDialogAccess.setCancelable(false);
            new DialogViewHolderAcceptShare(accessAlertDialogView);
            alertDialogAccess.setView(accessAlertDialogView);
            dismissAccessDialog = alertDialogAccess.show();
        }else {
            dismissAccessDialog.show();
        }
    }
}
