Question

在屏幕上，有一个具有焦点的ImageView。当通过coolNavbarView.setVisiblity(View.GONE)显示新视图时，新视图会抢断焦点。如果用户导航到该视图，新视图应该能够变得可聚焦，但是一旦显示它就不应该立即窃取焦点。重点应该放在已经有焦点的ImageView上。

我知道一种setFocusable(boolean)方法可让视图变得可调焦，是否有setStealFocusOnVisible(boolean)方法？

这是关于如何聚焦的堆栈跟踪。

对于我的情况，ListView正在窃取焦点。我能够通过从ListView中删除Focusable属性来修复它，然后才能使ListView可见

ListView v = ViewUtils.findViewById(view, listLayoutId, ListView.class);
v.setFocusable(false);

在可见时查看窃取辅助功能焦点
