View0 is a 1DP layout in activity, which means that the popwindows is displayed in full screen.

　　

The previous programmer used Popwindows to write a full-screen pop-up window, which nested a ListView display data. The question came, and at 7.1 it became the image below. Test phone, Xiaomi Mix2, System version, Android 7.1.1

The final solution is to set the hidden progress bar in the ListView. Android:scrollbars= "None" guess is the sliding of the ListView and Popwindow layout conflict, and so a big guy from the source level analysis.
