这里通过log来查看触控笔的motionEvent，

java 复制代码 
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        Log.i(tag, "event=" + event);
        return true;
    }

    @Override
    public boolean onGenericMotionEvent(MotionEvent event) {
        Log.i(tag, "G event=" + event);
        return true;
    }

在靠近屏幕时，调用到onGenericMotionEvent

在触碰到屏幕时，调用onTouchEvent,

toolType[0]=TOOL_TYPE_STYLUS

一次点击的完整log

在 Android 中，触控笔（Stylus）是一种特殊的输入设备，它可以提供更精确和细致的输入方式。Android 提供了相应的触控笔事件处理机制，以支持触控笔的使用。

触控笔事件与触摸事件略有不同，因为触控笔通常提供了更多的信息，如压力、倾斜角度等。在处理触控笔事件时，你可以使用以下方法和属性：

  1. onTouchEvent(): 在 View 或 Activity 中重写 onTouchEvent() 方法，可以接收触控笔事件。你可以根据事件的类型和属性来处理触控笔事件。

  2. MotionEvent: 触控笔事件使用 MotionEvent 类表示，它提供了许多有用的方法来获取触控笔事件的信息。例如，使用 event.getToolType() 方法可以检测事件的工具类型，通过 event.getPressure() 方法可以获取触压力度，使用 event.getOrientation() 方法可以获取触控笔的倾斜角度等。

在 Android 中，onGenericMotionEvent() 是一个回调方法，用于处理通用输入事件（Generic Motion Event）。它是 View 类的一个方法，用于接收并处理与输入设备相关的通用事件。

通用输入事件可以包括鼠标、轨迹球、游戏手柄等多种输入设备的事件。这些事件与触摸事件略有不同，因为它们提供了更丰富的输入信息，如鼠标滚轮的滚动、轨迹球的移动、游戏手柄的摇杆操作等。
