Java 在alertDialog内显示Recyclerview

我想在AlertDialog中显示我的Recyclerview，就像代码一样，我很确定我已经在视频中看到了，但是当我打开AlertDialog时，它总是强制关闭。你们能帮帮我吗？我是新用户使用android studio

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

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();
                                }
                            });

• 在style.xml中定义对话框样式

  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();
  

  
  真的
  @android：彩色/透明
  @空的
  真的

使用“自定义布局”对话框将自定义布局添加到对话框中。尝试使用下面给定的代码。 希望这将是一个有用的答案

imgTest.setOnClickListener(new View.OnClickListener() {
                                @Override

                                    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);

对话框上下文必须是活动

<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>
