java - 如何删除textview的滚动？

Question

我有一个 TextView，我在 Java 中将其称为“消息”，并将其设置为可滚动，如下所示:

 message.setMovementMethod(new ScrollingMovementMethod());

我有另一个名为“停止”的按钮，它会从消息 TextView 中移除滚动焦点。如何移除焦点并停止滚动？

Answer 1

来自TextView.setMovementMethod(MovementMethod)-method文档:

Sets the movement method (arrow key handler) to be used for this TextView. This can be null to disallow using the arrow keys to move the cursor or scroll the view.

Be warned that if you want a TextView with a key listener or movement method not to be focusable, or if you want a TextView without a key listener or movement method to be focusable, you must call setFocusable(boolean) again after calling this to get the focusability back the way you want it.

所以这应该移除焦点:

message.setFocusable(false);

虽然这将完全消除滚动:

message.setMovementMethod(null);
