1、
注意，不是这个文件：
Y:\RK3576_Android14.0_SDK_RELEASE\frameworks\native\services\inputflinger\InputReaderBase.cpp
2、问 DeepSeek：
给RK3576的Android14的SDK 增加 鼠标右键 返回的功能？
方案二：修改框架层代码（核心方法）
这个方法直接修改Android输入系统的核心逻辑，在所有Android版本上都有效。主要的修改点在于 InputReader.cpp 文件。
cpp
// 文件路径位于 frameworks/native/services/inputflinger/InputReader.cpp
// 在 CursorButtonAccumulator::getButtonState() 函数中修改
uint32_t CursorButtonAccumulator::getButtonState() const {
uint32_t result = 0;
if (mBtnLeft) {
result |= AMOTION_EVENT_BUTTON_PRIMARY;
}
if (mBtnRight) {
// 将原本的 "AMOTION_EVENT_BUTTON_SECONDARY" 改为 "AMOTION_EVENT_BUTTON_BACK"
// result |= AMOTION_EVENT_BUTTON_SECONDARY;
result |= AMOTION_EVENT_BUTTON_BACK;
}
// ... 其他按钮的处理代码保持不变
return result;
}
这个修改直接改变了右键事件的原始状态，因此通常修改这一个函数即可。
3、通过grep找到修改的地方：
