视图在可见时窃取辅助功能焦点

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，新视图会抢走焦点。如果用户导航到新视图，它应该能够变得可聚焦，但它不应该在显示后立即抢走焦点。焦点应该停留在已经有焦点的 ImageView 上。

我知道有一个 setFocusable(boolean) 方法可以让视图成为焦点，有没有 setStealFocusOnVisible(boolean) 方法？

这是它如何成为焦点的堆栈跟踪。

Answer 1

就我而言，ListView 抢走了焦点。我能够通过在使 ListView 可见之前从 ListView 中删除 Focusable 属性来修复它

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