我有一个 PopupWindow，它在按下按钮时显示一个 WebView。如果 setBuiltInZoomControls 设置为false，则 WebView 按预期显示页面。但是，如果 setBuiltInZoomControls 设置为true，则与 WebView（滚动、捏合缩放）的任何交互都会导致错误。

这是Java代码：

  mHelpButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            LayoutInflater inflater = (LayoutInflater) getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
            View popupView = inflater.inflate(R.layout.help_pop, null);
            int width = WindowManager.LayoutParams.MATCH_PARENT;
            int height = WindowManager.LayoutParams.WRAP_CONTENT;
            final PopupWindow popupWindow = new PopupWindow(popupView, 1, 1, true);
            popupWindow.setWindowLayoutMode(width,height);
            popupWindow.setOutsideTouchable(true);
            popupWindow.setBackgroundDrawable(new BitmapDrawable(getResources(), ""));
            TextView helpText = (TextView) popupView.findViewById(R.id.help_text);
            WebView webView = (WebView)popupView.findViewById(R.id.app_question_help_web_view);
            if (!mQuestion.casiHelpText.contains("http://") && !mQuestion.casiHelpText.contains("<")) {
                helpText.setText(mQuestion.casiHelpText);
                popupWindow.showAsDropDown(mHelpButton);
            } else if (mQuestion.casiHelpText.contains("http://") && !mQuestion.casiHelpText.contains("<")) {
                if …
