Android 将RecyclerView（RecyclerFragment）添加到对话框

我有自定义的RecyclerView来创建ListView。 当我试图在布局的id中填充列表视图时，它非常有效

FragmentTransaction ft = getFragmentManager().beginTransaction();
Bundle bundle = new Bundle();
bundle.putBoolean("enablePullToRefresh", false);
GridValues gridValues = new GridValues();
gridValues.rowViewLayout = R.layout.my_detail_row_view;

gridValues.delegate = this;

mygrid = new CustomGridView(gridValues, bundle);
mygrid.showAsGrid = true;
mygrid.spanCount = 2;
mygrid.layoutOrientation = LinearLayoutManager.VERTICAL;
mygrid.noRowColor = true;
mygrid.gridName = "mygrid";

mygrid.setArguments(mygrid.bundle);
ft.replace(R.id.MyGridContainer, mygrid);

现在，我想在对话框中填充一个新列表。 我该怎么做

我尝试了这个，把我的网格设为静态网格

public static class MyDialogFragment extends DialogFragment {
    static MyDialogFragment newInstance() {
        return new MyDialogFragment();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return mygrid.getView();
    }
}

然后呢,

FragmentTransaction ft = getFragmentManager().beginTransaction();
DialogFragment newFragment = MyDialogFragment.newInstance();
ft.add(R.id.MyGridContainer, newFragment);
//getView().findViewById(R.id.MyGridContainer).setVisibility(View.VISIBLE);
ft.commit();

假设您有一个名为mygrid的静态normal片段，下面是DialogFragment的外观：

public class MyDialogFragment extends DialogFragment {
    static MyDialogFragment newInstance() {
        return new MyDialogFragment();
    }

    // this method create view for your Dialog
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return mygrid.getView();
    }

    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = new Dialog(getActivity());
        return dialog;
    }
}

以下是您应该如何展示它：

DialogFragment fragment = MyDialogFragment.newInstance();
fragment.show(getSupportFragmentManager(), "some tag"); // please refer to DialogFragment#show() method in documentations.

---

DialogFragment只是另一个片段，像处理任何其他片段一样膨胀自定义视图

public class MyDialogFragment extends DialogFragment {
    private RecyclerView mRecyclerView;
    private MyRecyclerAdapter adapter;
    // this method create view for your Dialog
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
          //inflate layout with recycler view
         View v = inflater.inflate(R.layout.fragment_dialog, container, false);
        mRecyclerView = (RecyclerView) v.findViewById(R.id.recycler_view);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
        //setadapter
        CustomAdapter adapter = new MyRecyclerAdapter(context, customList);
            mRecyclerView.setAdapter(adapter);
         //get your recycler view and populate it.
         return v;
    }
}

在对话框片段中显示RecyclerView和在普通片段中一样简单。但要在对话框片段中显示，您需要创建一个如下对话框：

public class AppDialogs extends DialogFragment {
private AlertDialog.Builder builder;

public static AppDialogs newInstance(int dialogNo, String title, String msg)
{
    AppDialogs fragment = new AppDialogs();
    Bundle args = new Bundle();
    args.putInt("dialogNo",dialogNo);
    args.putString("title", title);
    args.putString("msg", msg);
    fragment.setArguments(args);

    return fragment;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState)
{
    if(android.os.Build.VERSION.SDK_INT<=android.os.Build.VERSION_CODES.KITKAT) {
        getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.argb(0, 0, 0, 0)));
    }
    return null;
}


@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    Bundle bundle = getArguments();
    int pos = bundle.getInt("dialogNo");
    switch (pos) {
        case 0:
            return  showList();


    }

    return super.onCreateDialog(savedInstanceState);

}


private Dialog showList() {
    builder = new AlertDialog.Builder(getActivity(), R.style.app_dialog_theme);
    builder.setTitle(title);


RecyclerView rView;
  builder.setView(rView);

        return builder.create();
    }
}

公共类AppDialogs扩展DialogFragment{
私有AlertDialog.Builder；
公共静态AppDialogs newInstance（int dialogNo、字符串标题、字符串消息）
{
AppDialogs片段=新建AppDialogs（）；
Bundle args=新Bundle（）；
args.putInt（“dialogNo”，dialogNo）；
args.putString（“title”，title）；
args.putString（“msg”，msg）；
fragment.setArguments（args）；
返回片段；
}
@凌驾
CreateView上的公共视图（布局、充气机、视图组容器、捆绑包保存状态）
{
if（android.os.Build.VERSION.SDK_INT接受的答案是可行的，但它需要额外的努力才能让它更像标准对话框

下面是另一种可能的方法，它允许您保留所有对话框功能（例如标题、图标、正/负/中性按钮）。其思想是覆盖
onCreateDialog
并使用
AlertDialog.Builder\setView（）
方法

public class MyDialogFragment extends DialogFragment {
    private RecyclerView mRecyclerView;

    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        mRecyclerView = new RecyclerView(getContext());
        // you can use LayoutInflater.from(getContext()).inflate(...) if you have xml layout
        mRecyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
        mRecyclerView.setAdapter(/* your adapter */);

        return new AlertDialog.Builder(getActivity())
                .setTitle(/* your title */)
                .setView(mRecyclerView)
                .setPositiveButton(android.R.string.ok,
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int whichButton) {
                                // do something
                            }
                        }
                ).create();
    }
}

只需应用与普通
片段应用相同的逻辑，为什么不使用AlertDialog.Builder方法？在那里可以调用addView（）@Blackbelt，我尝试过使用FragmentTransaction，但不幸的是它不起作用。我不太了解核心概念，我还是一名学习者。请发布什么是
CustomGridView
@bGorle只是一个RecyclerView，InSpred（！）from.。嗨，当我添加recycler视图并启用滚动条时，滚动条不可见（即使在XML中设置了scrollbars=vertical，我也尝试了设置drawable）。我认为这可能与主题有关。你知道为什么吗？
