软键盘在 Android 中的活动中打开和关闭侦听器 [英] Soft keyboard open and close listener in an activity in Android

问题描述

我有一个 Activity，其中有 5 个 EditText.当用户单击第一个 EditText 时，软键盘打开以在其中输入一些值.我想在软键盘打开时以及当用户单击第一个 EditText 时将其他 View 的可见性设置为 Gone当软键盘从后退按钮上的相同 EditText 关闭时.然后我想将其他一些 View 的可见性设置为可见.

I have an Activity where there are 5 EditTexts. When the user clicks on the first EditText, the soft keyboard opens to enter some value in it. I want to set some other View's visibility to Gone when the soft keyboard opens and also when the user clicks on the first EditText and also when the soft keyboard closes from the same EditText on the back button press. Then I want to set some other View's visibility to visible.

当点击 Android 中的第一个 EditText 软键盘打开时，是否有任何侦听器或回调或任何黑客攻击?

Is there any listener or callback or any hack for when the soft keyboard opens from a click on the first EditText in Android?

推荐答案

小菜一碟KeyboardVisibilityEvent 库

KeyboardVisibilityEvent.setEventListener(
    getActivity(),
    new KeyboardVisibilityEventListener() {
        @Override
        public void onVisibilityChanged(boolean isOpen) {
            // Ah... at last. do your thing :)
        }
    });
