在alertDialog中显示Recyclerview

Question

imgTest.setOnClickListener(new View.OnClickListener() {
                                @Override
                                public void onClick(View v) {
                                    final AlertDialog.Builder mBuilder  =   new AlertDialog.Builder(getApplicationContext());
                                    mBuilder.setTitle("Location Available!");
                                    LayoutInflater inflater =   getLayoutInflater();
                                    View convertView        =   inflater.inflate(R.layout.reclycer_data, null);

                                    RecyclerView list       =   convertView.findViewById(R.id.recView);
                                    list.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
                                    list.setAdapter(adapter);
                                    AlertDialog dialog      =   mBuilder.create();
                                    dialog.show();
                                }
                            });

我想像代码一样在AlertDialog中显示我的Recyclerview，我敢肯定我已经在视频中关注了，但是当我打开alertDialog时，它总是强制关闭。 你们能帮我吗？ 我是新使用的android studio

Answer 1

使用自定义布局对话框将自定义布局添加到对话框。 尝试使用下面给出的代码。 希望这将是一个有用的答案。

final Dialog dialog = new Dialog(getApplicationContext(), R.style.FullHeightDialog);

    dialog.setContentView(R.layout.reclycer_data);
    dialog.setCancelable(false);

    if (dialog.getWindow() != null){
        dialog.getWindow().setLayout(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    }

    RecyclerView list = dialog.findViewById(R.id.recView);
    list.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
    list.setAdapter(adapter);

dialog.show();

• 在style.xml中定义对话框样式

   <style name="FullHeightDialog" parent="Base.Theme.AppCompat.Light.Dialog"> <item name="android:windowNoTitle">true</item> <item name="android:windowBackground">@android:color/transparent</item> <item name="android:windowFrame">@null</item> <item name="android:windowFullscreen">true</item> </style>

对话框上下文必须活动

    final AlertDialog.Builder mBuilder = new AlertDialog.Builder(YouActivity.this);
    mBuilder.setTitle("Location Available!");
    LayoutInflater inflater = getLayoutInflater();
    View convertView = inflater.inflate(R.layout.reclycer_data, null);

    RecyclerView list = convertView.findViewById(R.id.recView);
    list.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
    list.setAdapter(adapter);
    mBuilder.setView(convertView); // setView

    AlertDialog dialog = mBuilder.create();
    dialog.show();
