全屏
PopupWindow mPopupWindow = new PopupWindow(popupView, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT, true);
设置高度MATCH_PARENT后，不管怎么设置mPopupWindow.showAsDropDown(view);或者mPopupWindow.showAtLocation(view,Gravity.NO_GRAVITY,0,view.getHeight());都会显示在全屏显示在屏幕左上角...
处理方式 修改高度WRAP_CONTENT
注意：在安卓7.0上请看下面要注意的地方
/**
- 在android7.0上，如果不主动约束PopuWindow的大小，比如，设置布局大小为 MATCH_PARENT,那么PopuWindow会变得尽可能大，以至于 view下方无空间完全显示PopuWindow，而且view又无法向上滚动，此时PopuWindow会主动上移位置，直到可以显示完全。
* 解决办法：主动约束PopuWindow的内容大小，重写showAsDropDown方法： - @param anchor
*/
@Override
public void showAsDropDown(View anchor) {
if(Build.VERSION.SDK_INT >= 24){
Rect visibleFrame = new Rect();
anchor.getGlobalVisibleRect(visibleFrame);
int height = anchor.getResources().getDisplayMetrics().heightPixels - visibleFrame.bottom;
setHeight(height);
}
super.showAsDropDown(anchor);
}
遮罩处理
设置WRAP_CONTENT，遮罩不显示，设置父控件背景色无效,只能添加新的View

关于ListView
- 取消ListView的默认分割线android:divider="@null"
- 设置ListView item的高度无效 android:minHeight="52dp"
- 设置ListView item的margin无效 添加相关的padding属性

点击外部popwindow不消失
popupWindow = new PopupWindow(LayoutInflater.from(MainActivity.this).inflate(R.layout.pop_list, null), ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT, true);
改成如下：
popupWindow = new PopupWindow(LayoutInflater.from(MainActivity.this).inflate(R.layout.pop_list, null), ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, true);
原因很简单，因为前者这样写得话，popupWindow 把整个window都遮挡了，所以popupWindow.setOutsideTouchable(true)并没有起到作用，所以失效
