是什么触发（或产生）KeyEvent.ACTION_MULTIPLE？ [英] What triggers (or generates) KeyEvent.ACTION_MULTIPLE?
问题描述
的文档<一个href="http://developer.android.com/reference/android/view/KeyEvent.html#ACTION_MULTIPLE">KeyEvent.ACTION_MULTIPLE说：
多个重复的关键事件都发生在一排，或复杂 串被传递。如果密钥code不是{#LINK KEY code_UNKNOWN那么{#LINK getRepeatCount（）方法返回 次数定键code应该执行。否则，如果 关键code是关键code_UNKNOWN，那么这是一个字符序列 通过getCharacters（）作为返回。
"multiple duplicate key events have occurred in a row, or a complex string is being delivered. If the key code is not {#link KEYCODE_UNKNOWN then the {#link getRepeatCount() method returns the number of times the given key code should be executed. Otherwise, if the key code is KEYCODE_UNKNOWN, then this is a sequence of characters as returned by getCharacters()."
不过，这并不说如何以实际生成的事件。
But it doesn't say how to actually generate that event.
- 在我试过（快速）双击我收到了耳机的暂停/播放键，但都是普通ACTION_UP和ACTION_DOWN。
- 我也试过 pressing并按住耳机的暂停/播放键，但我收到的普通ACTION_UP和ACTION_DOWN。
- I tried (rapidly) double-clicking the headset's Pause/Play button, but all I receive is ordinary ACTION_UP and ACTION_DOWN.
- I also tried pressing and holding down the headset's Pause/Play button, but all I receive is ordinary ACTION_UP and ACTION_DOWN.
如何生成一个<一个href="http://developer.android.com/reference/android/view/KeyEvent.html#ACTION_MULTIPLE">KeyEvent.ACTION_MULTIPLE （作为一个用户，使用耳机控制）？
How do I generate a KeyEvent.ACTION_MULTIPLE (as a user, using a headset control)?
推荐答案
Android的<一个href="https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/java/android/text/method/BaseMovementMethod.java"相对=nofollow> BaseMovementMethod 包括code办理 ACTION_MULTIPLE 所以psumably是关键自动重复生成的事件$ P $当用户持有向下箭头键。
Android's BaseMovementMethod includes code for handling ACTION_MULTIPLE so presumably the event is generated for key auto-repeat when the user holds down an arrow key.
