Android手机输入法按键监听-dispatchKeyEvent
2024-09-21 06:34:11
近期在项目开发中遇到一个关于手机输入键盘的坑。特来记录下。
应用场景：
项目中有一个界面是用viewpaper加三个fragment写的，当中viewpaper被我屏蔽了左右滑动，上面有三个点击按钮，点击他们能够切换页面（不要问我为什么这么写，由于你不知道需求有多么的操蛋）。每一个fragment里面都有五六个竖着排列的edittext。仅仅有一个fragment里面的edittext都填写了才让跳到下一个。大致效果图例如以下：
遇到的问题
測试的时候发现一个问题（说实话确实非常佩服这个測试妹子，这都能測出来！），当把输入法切换成手写全屏后（记住是全屏手写），酷派手机键盘上会有上下左右四个方向按钮。
其它手机可能仅仅有两个，不同手机可能不一样。当点击四个按钮的时候会发现界面能够上下左右跳转，能从第一个fragment跳到第二个fragment。
。。也就是说推断edittext是否填写的推断无效了。禁止滑动也无效了！！。
解决方法：
重写Activity中的dispatchKeyEvent事件然后相应按键进行处理：
@Override
public boolean dispatchKeyEvent(KeyEvent event) {
// TODO Auto-generated method stub
if (event.getKeyCode() == KeyEvent.KEYCODE_DPAD_LEFT
|| event.getKeyCode() == KeyEvent.KEYCODE_DPAD_UP
|| event.getKeyCode() == KeyEvent.KEYCODE_DPAD_RIGHT
|| event.getKeyCode() == KeyEvent.KEYCODE_DPAD_DOWN) {
return true;
}
return super.dispatchKeyEvent(event);
}KEYCODE_DPAD_LEFT （21）、KEYCODE_DPAD_UP （19）、KEYCODE_DPAD_RIGHT （22）、KEYCODE_DPAD_DOWN （20）这四个值相应的就是键盘上的四个按钮（左、上、右、下）的值。这里我的处理方案是直接给屏蔽了他的点击事件，相应的处理逻辑能够自己写。
这里另一点要说下：
如上图这里键盘也有自带的上下左右用于粘贴复制等操作，这四个键的keyCode跟上面四个的是一样的。只是有一点不同，就是当editText里面没有写东西的时候会检測不到按键。
再说下dispatchKeyEvent：
当键盘按下时的触发顺序 -> dispatchKeyEvent –> onUserInteraction –> onKeyDown
假设按下紧接着松开。则是触发两次。紧跟再触发–> dispatchKeyEvent –> onUserInteraction
–>onKeyUp
dispatchKeyEvent是做按键处理和分发的工作，假设你想要onKeyDown还能够接收到应该这样实现
public boolean dispatchKeyEvent(KeyEvent event){
return super.dispatchKeyEvent(event);
}最后给大家附上键盘按键的code值：
