Baidu map development-mark multiple locations on the map, click the node pop-up PopupWindow, node popupwindow

Baidu map development-mark multiple locations on the map, click the node pop-up PopupWindow, node popupwindow

I recently wrote an android program and used some content of Baidu map API.

This DEMO is used to mark multiple locations on the map, and then click the node to pop up the PopupWindow

Below are some:

Main. xml

Why can't I click another widget after the pop-up window of PopupWindow in android

Because PopupWindow gets the focus and others do not get the focus, you cannot click it. Set setFocusable to false.
 
My mark on Baidu map will pop up and the data will be deleted after a while. How can I not be deleted?

Because you are not a Baidu employee, and the advertisement you mark is too high.
