Android沉浸式模式用于下拉，隐藏导航栏

Question

将listview添加到PopupWindow对象，点击导航键栏弹出，是否有办法在点击下拉列表时阻止导航栏。

Answer 1

在下拉项目

的onclick中尝试此片段

View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
              | View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
