listpopupwindow

mListPopupWindow = new ListPopupWindow(mActivity);

       mListPopupWindow.setAdapter(new NavAdapter(mActivity, itmes));
       mListPopupWindow.setWidth(DisplayUtils.getScreenWidthPixels(mActivity) / 2);
       mListPopupWindow.setHeight(DisplayUtils.getScreenWidthPixels(mActivity) * 3 / 5);
       mListPopupWindow.setAnchorView(titleTv);
       mListPopupWindow.setVerticalOffset(titleTv.getHeight() / 2);
       mListPopupWindow.setBackgroundDrawable(mActivity.getResources().getDrawable(R.drawable.popover_background));
       mListPopupWindow.setOnDismissListener(new OnDismissListener() {

           @Override
           public void onDismiss() {
               titleIv.setImageResource(R.drawable.navigationbar_arrow_down);
           }
       });
       mListPopupWindow.setOnItemClickListener(new OnItemClickListener() {
           @Override
           public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
               ToastUtils.showToast(mActivity, "点击了" + itmes.get(position).getName(), 1000);
           }

});

popupwindow

        if (mPopupWindow == null) {
           view = this.getLayoutInflater().inflate(R.layout.popupwindow_nav, null);
           lv_group = (ListView) view.findViewById(R.id.lvGroup);
           // 加载数据
           itmes = new ArrayList<>();
           itmes.add(“首页”);
           itmes.add(“我的微博”);
           itmes.add(“我的分组”);
           lv_group.setAdapter(new NavAdapter(this, itmes));
           int width = DisplayUtils.getScreenWidthPixels(this) / 2;
           int height = DisplayUtils.getScreenHeightPixels(this) / 2;
           // 创建一个PopuWidow对象
           mPopupWindow = new PopupWindow(view, width, height);
           // 设置允许在外点击消失
           mPopupWindow.setOutsideTouchable(true);
       }

       // 这个是为了点击“返回Back”也能使其消失，并且并不会影响你的背景
       mPopupWindow.setBackgroundDrawable(new ColorDrawable(0));
       // 显示的位置为:屏幕的宽度的一半-PopupWindow的高度的一半
       // int xPos = DisplayUtils.getScreenWidthPixels(mActivity) / 2
       // - mPopupWindow.getWidth() / 2;
       mPopupWindow.setOnDismissListener(new OnDismissListener() {

           @Override
           public void onDismiss() {
               // titleIv.setImageResource(R.drawable.navigationbar_arrow_down);
           }
       });
       lv_group.setOnItemClickListener(new OnItemClickListener() {
           @Override
           public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
               // ToastUtils.showToast(this, "点击了" +
               // itmes.get(position), 1000);
           }
       });

mPopupWindow.showAsDropDown(iv_add); 或者 mPopupWindow.showatLocation();
mPopupWindow.setFocusable(true);

目前Fragment里调用PopupWindow会出现设置PopupWindow的大小无效的情况，尚未解决！！！
