Question

我是Android新手，我正在尝试在弹出窗口中集成auto complete text view。但是弹出窗口内的自动完成操作无效。如果我将自动完成文本视图放在弹出窗口之外，则自动完成工作正常。

弹出窗口的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);

我在谷歌搜索过。我可以找到警告对话框的解决方案，但不能找到模态窗口。如何解决这个问题？

@覆盖 public void onCreate（Bundle savedInstanceState）{ super.onCreate（savedInstanceState）; 的setContentView（R.layout.activity_my）;

    final Button btnOpenPopup = (Button)findViewById(R.id.openpopup);
    btnOpenPopup.setOnClickListener(new Button.OnClickListener(){

        @Override
        public void onClick(View arg0) {
            LayoutInflater layoutInflater = (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
            View popupView = layoutInflater.inflate(R.layout.activity_popup, null);

            final PopupWindow popupWindow = new PopupWindow(
                    popupView, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT, true);


            popupView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);

            final EditText text = (EditText)popupView.findViewById(R.id.editText); // to write Review notes

            final TextView txtRatingValue = (TextView)popupView.findViewById(R.id.txtRatingValue); // Rating Value

            final RatingBar   ratingBar = (RatingBar)popupView.findViewById(R.id.ratingBar);
            ratingBar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
                public void onRatingChanged(RatingBar ratingBar, float rating,
                                            boolean fromUser) {

                    txtRatingValue.setText(String.valueOf(rating));

                }
            });

            // popupView.addListenerOnRatingBar();


            Button  ok = (Button )popupView.findViewById(R.id.ok); // Database Codes to store the apps rating and review Data
            ok.setOnClickListener(new Button.OnClickListener() {

                @Override
                public void onClick(View v) {

                    Toast.makeText(MyActivity.this, "Reminder Nikhil Keshri's Database code to Be added here....", Toast.LENGTH_LONG).show();

                }
            });

            Button clear = (Button)popupView.findViewById(R.id.clear); // clearing button
            clear.setOnClickListener(new Button.OnClickListener() {

                @Override

                    //  txtRatingValue.setText("0.0");

                }
            });


            // text.setBackgroundColor();
            Button close = (Button)popupView.findViewById(R.id.close); // closing the popup window
            close.setOnClickListener(new Button.OnClickListener() {

                @Override
                public void onClick(View v) {

                    popupWindow.dismiss();
                }
            });

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

        }});
}

我遇到了同样的问题，但最终我还是使用父项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，但是如果您坚持使用popupwindow。然后，这就是它的工作方式。
1。在您的父级活动中创建autocompletetextview，将其放置在要显示列表的位置，并使可见性消失。
2.现在在popupwindow中，当您调用textwatcher或textchange时，请将数据适配器设置为父级自动完成文本视图，而不是popupwindow自动完成文本视图，并将可见性设置为visible。
3.当您键入任何字符时，它将显示项目列表。

希望有帮助！
