View popupView = getLayoutInflater().inflate(R.layout.textview_change, null); DropDownMenu mMenu_ziti = (DropDownMenu) popupView.findViewById(R.id.menu_ziti);

mPopupWindow = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, true); mPopupWindow.setFocusable(true); // mPopupWindow.setOutsideTouchable(false); mPopupWindow.setBackgroundDrawable(getDrawable(R.color.white)); mPopupWindow.showAtLocation(rLayout, Gravity.CENTER, 0, 0); 最后运行结果看不到这个控件,在这个控件的外面包裹一个黑色背景的布局,可以看到这个布局, 没有报错,没有错误log. 我把代码分离出来,写了个Demo,结果可以显示没问题. 有谁知道为什么吗????????????

你这个需求应该做不了~ DropDownMenu本身就是使用PopupWindow实现，这相当于在PopupWindow上弹PopupWindow，这个应该实现不了~
