我想在EditText上同时听三个不同的事件
我正在使用带软键盘的触摸屏。具体来说，我想将这些事件记录到文件中以供进一步处理。问题是我无法同时收听所有三个事件。此外，我根本无法捕捉到软键盘事件。当我搜索时，我发现我用于键事件的代码仅适用于硬键盘，但我想从软键盘中捕获这些事件。
我在堆栈溢出中读了几个答案但是它们没有解决我的问题，比如
How to combine OnClickListener and OnTouchListener for an ImageButton
touchEvent while typing with soft keyboard android
Receiving onTouch and onClick events with Android
我一直试图解决这个问题好几天但是我没有成功。我在触摸监听器上返回false以允许其他监听器捕获事件但是这也没有解决问题。任何帮助或指导将受到高度赞赏。

我必须创建自定义键盘，以便在同时获取加速度数据的同时处理触摸和按键。
