英文:
Unable to Get Mouse Button Release Events Android NDK
问题
我正在尝试在Android NDK和本机活动应用程序中获取鼠标按钮事件。
但似乎无法检测到鼠标按钮释放事件！
当我按下任何按钮时，AMOTION_EVENT_ACTION_DOWN 部分有效
但是当我释放该按钮时，AMOTION_EVENT_ACTION_UP 不起作用
Android API级别为30
在handle_input_event 回调中，我使用：
// LOGI 只是一个 __android_log_print 的宏
int32_t eventType = AInputEvent_getType(event);
int32_t eventAction = AKeyEvent_getAction(event);
switch(eventType)
{
case AINPUT_EVENT_TYPE_MOTION:
{
int32_t eventPointerIndex = (eventAction & AMOTION_EVENT_ACTION_POINTER_INDEX_MASK) >> AMOTION_EVENT_ACTION_POINTER_INDEX_SHIFT;
eventAction &= AMOTION_EVENT_ACTION_MASK;
switch(eventAction)
{
case AMOTION_EVENT_ACTION_DOWN: // 这部分正常工作并打印所有内容
{
int32_t toolType = AMotionEvent_getToolType(event, eventPointerIndex);
switch (toolType)
{
case AMOTION_EVENT_TOOL_TYPE_MOUSE:
{
int32_t mouseButton = AMotionEvent_getButtonState(event);
if (mouseButton & AMOTION_EVENT_BUTTON_PRIMARY)
LOGI("左键按下");
else if(mouseButton & AMOTION_EVENT_BUTTON_SECONDARY)
LOGI("右键按下");
else if(mouseButton & AMOTION_EVENT_BUTTON_TERTIARY)
LOGI("第三键按下");
break;
}
case AMOTION_EVENT_TOOL_TYPE_UNKNOWN:
default:
break;
}
break;
}
case AMOTION_EVENT_ACTION_UP: // 这不起作用并且不打印任何内容
{
int32_t toolType = AMotionEvent_getToolType(event, eventPointerIndex);
switch (toolType)
{
case AMOTION_EVENT_TOOL_TYPE_MOUSE:
{
int32_t mouseButton = AMotionEvent_getButtonState(event);
LOGI("mouseButton=%d", mouseButton);
if (mouseButton & AMOTION_EVENT_BUTTON_PRIMARY)
LOGI("左键释放");
else if(mouseButton & AMOTION_EVENT_BUTTON_SECONDARY)
LOGI("右键释放");
else if(mouseButton & AMOTION_EVENT_BUTTON_TERTIARY)
LOGI("第三键释放");
break;
}
case AMOTION_EVENT_TOOL_TYPE_UNKNOWN:
default:
break;
}
break;
}
}
}
}
这里有什么问题？
如何正确处理这个问题？
英文:
I'm trying to get mouse button events in Android NDK and Native Activity App
But it doesn't seem to detect the mouse button release event!
When I press any button AMOTION_EVENT_ACTION_DOWN part works
But when I release that button AMOTION_EVENT_ACTION_UP doesn't work
The Android API Level is 30
In the handle_input_event callback, I use:
// LOGI is just a macro for __android_log_print
int32_t eventType = AInputEvent_getType(event);
int32_t eventAction = AKeyEvent_getAction(event);
switch(eventType)
{
case AINPUT_EVENT_TYPE_MOTION:
{
int32_t eventPointerIndex = (eventAction & AMOTION_EVENT_ACTION_POINTER_INDEX_MASK) >> AMOTION_EVENT_ACTION_POINTER_INDEX_SHIFT;
eventAction &= AMOTION_EVENT_ACTION_MASK;
switch(eventAction)
{
case AMOTION_EVENT_ACTION_DOWN: // This works correctly and prints everything
{
int32_t toolType = AMotionEvent_getToolType(event, eventPointerIndex);
switch (toolType)
{
case AMOTION_EVENT_TOOL_TYPE_MOUSE:
{
int32_t mouseButton = AMotionEvent_getButtonState(event);
if (mouseButton & AMOTION_EVENT_BUTTON_PRIMARY)
LOGI("Left Click Press");
else if(mouseButton & AMOTION_EVENT_BUTTON_SECONDARY)
LOGI("Right Click Press");
else if(mouseButton & AMOTION_EVENT_BUTTON_TERTIARY)
LOGI("3rd Click Press");
break;
}
case AMOTION_EVENT_TOOL_TYPE_UNKNOWN:
default:
break;
}
break;
}
case AMOTION_EVENT_ACTION_UP: // This doesn't work correctly and prints nothing
{
int32_t toolType = AMotionEvent_getToolType(event, eventPointerIndex);
switch (toolType)
{
case AMOTION_EVENT_TOOL_TYPE_MOUSE:
{
int32_t mouseButton = AMotionEvent_getButtonState(event);
LOGI("mouseButton=%d", mouseButton);
if (mouseButton & AMOTION_EVENT_BUTTON_PRIMARY)
LOGI("Left Click Release");
else if(mouseButton & AMOTION_EVENT_BUTTON_SECONDARY)
LOGI("Right Click Release");
else if(mouseButton & AMOTION_EVENT_BUTTON_TERTIARY)
LOGI("3rd Click Release");
break;
}
case AMOTION_EVENT_TOOL_TYPE_UNKNOWN:
default:
break;
}
break;
}
}
}
}
What is wrong with this?
How do I do it correctly?

你可以尝试使用AMotionEvent_getAction而不是AKeyEvent_getAction来处理AINPUT_EVENT_TYPE_MOTION。
eventAction = AMotionEvent_getAction(event)
// 指针索引代码在这里
switch(eventAction & AMOTION_EVENT_ACTION_MASK)
// 案例和其他内容
英文:
You could try using AMotionEvent_getAction instead of AKeyEvent_getAction for AINPUT_EVENT_TYPE_MOTION.
eventAction = AMotionEvent_getAction(event)
// pointer index code here
switch(eventAction & AMOTION_EVENT_ACTION_MASK)
// cases and stuff
