自动完成文本视图在弹出窗口中不起作用

Question

我是 android 新手，我正在尝试将 auto complete text view 集成到弹出窗口中。但是自动完成操作在弹出窗口内不起作用。如果我将自动完成文本视图放在弹出自动完成之外就可以了。

弹窗xml代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:layout_gravity="center_horizontal"
   android:orientation="vertical" >

   <LinearLayout
       android:id="@+id/popup"
       android:layout_width="300dp"
       android:layout_height="match_parent"
       android:layout_gravity="center_horizontal"
       android:gravity="center_horizontal"
       android:orientation="vertical"
       tools:ignore="UselessParent" >

       <FrameLayout
     android:id="@+id/innertop"
     android:layout_width="match_parent"
     android:layout_height="55dp"
        >


     <AutoCompleteTextView
         android:id="@+id/listitem"
         style="@style/CodeFont"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:layout_marginBottom="4dp"
         android:background="@drawable/border"
         android:hint="@string/search_products_"
         android:textSize="12sp"
         android:typeface="serif" />

     <Button
         android:id="@+id/searchbtn1"
         android:layout_width="32dp"
         android:layout_height="32dp"
         android:layout_gravity="center_vertical|right"
         android:layout_marginRight="10dp"
         android:layout_marginBottom="1dp"
         android:background="@drawable/search_icon" />

 </FrameLayout>

   </LinearLayout>

</LinearLayout>

活动java代码：

final TextView btnOpenPopup1 = (TextView)findViewById(R.id.textView6);
                               btnOpenPopup1.setOnClickListener(new TextView.OnClickListener(){

                       @Override
                          public void onClick(View arg0) {
                           LayoutInflater layoutInflater
                            = (LayoutInflater)getBaseContext()
                             .getSystemService(LAYOUT_INFLATER_SERVICE);  
                           View popupView = layoutInflater.inflate(R.layout.login_popup, null);  
                                    final PopupWindow popupWindow = new PopupWindow(
                                      popupView,
                                      LayoutParams.WRAP_CONTENT,  
                                            LayoutParams.WRAP_CONTENT); 

                                    popupWindow.setFocusable(true);
                                    popupWindow.showAsDropDown(btnOpenPopup, -50, -70);

我在 Google 中搜索过。我可以找到警报对话框的解决方案，但找不到模式窗口的解决方案。如何解决这个问题？

我遇到了同样的问题，但我最终使用父活动在弹出窗口中显示项目。您可以使用对话框来解决此问题，但如果您坚持使用弹出窗口。然后，这就是它的工作方式。
1.在您的父活动中创建自动完成文本视图，将其放置在您想要显示列表的任何位置并使其可见性消失。
2.现在在弹出窗口中，当您调用 textwatcher 或 textchange 时，将该数据适配器设置为父自动完成文本视图而不是弹出窗口自动完成文本视图，并将可见性设置为可见。
3.它会在你输入任何字符时显示项目列表。

希望有所帮助！
