android - 如何同时监听触摸事件和软键盘事件

Question

我想在 EditText 上同时收听三个不同的事件

1. 文本更改事件
2. 触摸事件
3. 软键盘事件

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一个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。另外，我根本无法捕捉到软键盘事件。当我搜索时，我发现我用于按键事件的代码仅适用于硬键盘，但我想从软键盘捕获这些事件。

我在堆栈溢出中阅读了几个答案，但它们并没有解决我的问题，例如

How to combine OnClickListener and OnTouchListener for an ImageButton

touchEvent while typing with soft keyboard android

Receiving onTouch and onClick events with Android

几天来我一直在尝试解决这个问题，但没有成功。我在触摸监听器上返回 false 以允许其他监听器捕获事件，但这也没有解决问题。任何帮助或指导将不胜感激。

我必须创建自定义键盘才能同时处理触摸和按键，同时获取加速度数据。

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    // Inflate the layout for this fragment

    senSensorManager.registerListener(this, senAccelerometer , SensorManager.SENSOR_DELAY_NORMAL);

    initializeTheCSVfile();
