Question

我想在要放大弹出式布局的视图上显示一个弹出菜单。我正在为弹出功能使用弹出类。目前，我无法在视图上看到弹出窗口。

我检查了堆栈溢出的许多答案，并尝试应用对我仍然无效的答案。

这是我的弹出课程：

    public class PopUpClass {

        //PopupWindow display method

        //Create a View object yourself through inflater
        LayoutInflater inflater = (LayoutInflater) view.getContext().getSystemService(view.getContext().LAYOUT_INFLATER_SERVICE);
        View popupView = inflater.inflate(R.layout.popup_menu_layout, null);


        //Specify the length and width through constants
        int width = LinearLayout.LayoutParams.WRAP_CONTENT;
        int height = LinearLayout.LayoutParams.WRAP_CONTENT;

        //Make Inactive Items Outside Of PopupWindow
        boolean focusable = true;

        PopupWindow popupWindow = new PopupWindow(popupView,
                RelativeLayout.LayoutParams.WRAP_CONTENT,
                RelativeLayout.LayoutParams.WRAP_CONTENT);



/*       popupWindow.showAtLocation(view,Gravity.RIGHT,
                view.getWidth() - (view.getWidth()*50)/100,
                view.getHeight() - (view.getHeight()*10)/100);

        popupWindow.showAsDropDown(view, 0,
                -view.getHeight()-popupView.getHeight());*/

        //Create a window with our parameters
  /*      final PopupWindow popupWindow = new PopupWindow(popupView, width,
                height, focusable);*/



     //   Set the location of the window on the screen
/*    popupWindow.showAtLocation(view,
            view.getWidth() - popupWindow.getWidth(),
               view.getWidth(), view.getHeight());*/
    }

我通过提供被单击的视图来调用适配器中的弹出窗口。

holder.imageViewShare.setOnClickListener(new View.OnClickListener() {
            @Override public void onClick(View v) {

                        PopUpClass popUpClass = new PopUpClass();
                        popUpClass.showPopupWindow(v);
            }
        });

这是我的片段布局，其中包括共享之类的视图。我想在imageViewShare上打开弹出窗口

http://schemas.android.com/apk/res/android“ xmlns：app =“ http://schemas.android.com/apk/res-auto” xmlns：tools =“ http://schemas.android.com/tools” android：layout_width =“ match_parent” android：layout_height =“ match_parent” 工具：上下文=“ .QuotesFragment” android：background =“ @ drawable / bubbles_theme”>

        <RelativeLayout

            app:layout_constraintBottom_toBottomOf = "parent"
            app:layout_constraintEnd_toEndOf = "parent"
            app:layout_constraintStart_toStartOf = "parent"
            app:layout_constraintTop_toTopOf = "parent">

            <TextView
                android:id = "@+id/textView_quotes"

                android:textSize = "@dimen/text_size24" />

            <include
                android:id = "@+id/include2"

        </RelativeLayout>

这是share_save_like_layout

请对此进行指导。

这是它的外观

请帮助提供建议。谢谢。
