可以通过OH_Input_AddKeyEventMonitor(Input_KeyEventCallback callback)去创建按键事件监听从而处理用户的输入和表单。#include "multimodalinput/oh_input_manager.h" struct KeyEvent { int32_t action; int32_t keyCode; int64_t actionTime { -1 }; }; //定义按键事件回调函数 void OnKeyEventCallback(const Input_KeyEvent* keyEvent) { KeyEvent event; //Input_KeyEvent的生命周期仅在回调函数内,出了回调函数会被销毁 event.action = OH_Input_GetKeyEventAction(keyEvent); event.keyCode = OH_Input_GetKeyEventKeyCode(keyEvent); event.actionTime = OH_Input_GetKeyEventActionTime(keyEvent); } void TestMonitor() { //添加按键事件监听 Input_Result ret = OH_Input_AddKeyEventMonitor(OnKeyEventCallback); //移除按键事件监听 ret = OH_Input_RemoveKeyEventMonitor(OnKeyEventCallback); }参考链接:创建事件监听
