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：

  1. // LOGI 只是一个 __android_log_print 的宏
  3. int32_t eventType = AInputEvent_getType(event);
  4. int32_t eventAction = AKeyEvent_getAction(event);
  6. switch(eventType)
  7. {
  8.   case AINPUT_EVENT_TYPE_MOTION:
  9.   {
  10.     int32_t eventPointerIndex = (eventAction & AMOTION_EVENT_ACTION_POINTER_INDEX_MASK) >> AMOTION_EVENT_ACTION_POINTER_INDEX_SHIFT;
  11.     eventAction &= AMOTION_EVENT_ACTION_MASK;
  13.     switch(eventAction)
  14.     {
  15.       case AMOTION_EVENT_ACTION_DOWN: // 这部分正常工作并打印所有内容
  16.       {
  17.         int32_t toolType = AMotionEvent_getToolType(event, eventPointerIndex);
  19.         switch (toolType)
  20.         {
  21.           case AMOTION_EVENT_TOOL_TYPE_MOUSE:
  22.           {
  23.             int32_t mouseButton = AMotionEvent_getButtonState(event);
  25.             if (mouseButton & AMOTION_EVENT_BUTTON_PRIMARY)
  26.               LOGI("左键按下");
  27.             else if(mouseButton & AMOTION_EVENT_BUTTON_SECONDARY)
  28.               LOGI("右键按下");
  29.             else if(mouseButton & AMOTION_EVENT_BUTTON_TERTIARY)
  30.               LOGI("第三键按下");
  32.             break;
  33.           }
  35.           case AMOTION_EVENT_TOOL_TYPE_UNKNOWN:
  36.           default:
  37.             break;
  38.         }
  40.         break;
  41.       }
  42.       case AMOTION_EVENT_ACTION_UP: // 这不起作用并且不打印任何内容
  43.       {
  44.         int32_t toolType = AMotionEvent_getToolType(event, eventPointerIndex);
  46.         switch (toolType)
  47.         {
  48.           case AMOTION_EVENT_TOOL_TYPE_MOUSE:
  49.           {
  50.             int32_t mouseButton = AMotionEvent_getButtonState(event);
  51.             LOGI("mouseButton=%d", mouseButton);
  53.             if (mouseButton & AMOTION_EVENT_BUTTON_PRIMARY)
  54.               LOGI("左键释放");
  55.             else if(mouseButton & AMOTION_EVENT_BUTTON_SECONDARY)
  56.               LOGI("右键释放");
  57.             else if(mouseButton & AMOTION_EVENT_BUTTON_TERTIARY)
  58.               LOGI("第三键释放");
  60.             break;
  61.           }
  62.           case AMOTION_EVENT_TOOL_TYPE_UNKNOWN:
  63.           default:
  64.             break;
  65.         }
  67.         break;
  68.       }
  69.     }
  70.   }
  71. }

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:

  1. // LOGI is just a macro for __android_log_print
  3. int32_t eventType = AInputEvent_getType(event);
  4. int32_t eventAction = AKeyEvent_getAction(event);
  6. switch(eventType)
  7. {
  8.   case AINPUT_EVENT_TYPE_MOTION:
  9.   {
  10.     int32_t eventPointerIndex = (eventAction & AMOTION_EVENT_ACTION_POINTER_INDEX_MASK) >> AMOTION_EVENT_ACTION_POINTER_INDEX_SHIFT;
  11.     eventAction &= AMOTION_EVENT_ACTION_MASK;
  13.     switch(eventAction)
  14.     {
  15.       case AMOTION_EVENT_ACTION_DOWN: // This works correctly and prints everything
  16.       {
  17.         int32_t toolType = AMotionEvent_getToolType(event, eventPointerIndex);
  19.         switch (toolType)
  20.         {
  21.           case AMOTION_EVENT_TOOL_TYPE_MOUSE:
  22.           {
  23.             int32_t mouseButton = AMotionEvent_getButtonState(event);
  25.             if (mouseButton & AMOTION_EVENT_BUTTON_PRIMARY)
  26.               LOGI("Left Click Press");
  27.             else if(mouseButton & AMOTION_EVENT_BUTTON_SECONDARY)
  28.               LOGI("Right Click Press");
  29.             else if(mouseButton & AMOTION_EVENT_BUTTON_TERTIARY)
  30.               LOGI("3rd Click Press");
  32.             break;
  33.           }
  35.           case AMOTION_EVENT_TOOL_TYPE_UNKNOWN:
  36.           default:
  37.             break;
  38.         }
  40.         break;
  41.       }
  42.       case AMOTION_EVENT_ACTION_UP: // This doesn't work correctly and prints nothing
  43.       {
  44.         int32_t toolType = AMotionEvent_getToolType(event, eventPointerIndex);
  46.         switch (toolType)
  47.         {
  48.           case AMOTION_EVENT_TOOL_TYPE_MOUSE:
  49.           {
  50.             int32_t mouseButton = AMotionEvent_getButtonState(event);
  51.             LOGI("mouseButton=%d", mouseButton);
  53.             if (mouseButton & AMOTION_EVENT_BUTTON_PRIMARY)
  54.               LOGI("Left Click Release");
  55.             else if(mouseButton & AMOTION_EVENT_BUTTON_SECONDARY)
  56.               LOGI("Right Click Release");
  57.             else if(mouseButton & AMOTION_EVENT_BUTTON_TERTIARY)
  58.               LOGI("3rd Click Release");
  60.             break;
  61.           }
  62.           case AMOTION_EVENT_TOOL_TYPE_UNKNOWN:
  63.           default:
  64.             break;
  65.         }
  67.         break;
  68.       }
  69.     }
  70.   }
  71. }

What is wrong with this?

How do I do it correctly?

得分: 1

你可以尝试使用AMotionEvent_getAction而不是AKeyEvent_getAction来处理AINPUT_EVENT_TYPE_MOTION。

  1.   eventAction = AMotionEvent_getAction(event)
  2.   // 指针索引代码在这里
  3.   switch(eventAction & AMOTION_EVENT_ACTION_MASK)
  4.   // 案例和其他内容
英文:

You could try using AMotionEvent_getAction instead of AKeyEvent_getAction for AINPUT_EVENT_TYPE_MOTION.

  1.   eventAction = AMotionEvent_getAction(event)
  2.   // pointer index code here
  3.   switch(eventAction & AMOTION_EVENT_ACTION_MASK)
  4.   // cases and stuff
