How can I make Robot press and hold a mouse button for a certain period of time?
提问by Neutralise
I am using Java to generate a mouse press using the Robot class:
我正在使用 Java 使用 Robot 类生成鼠标按下：
robot.mousePress(InputEvent.BUTTON1_MASK);
robot.mouseRelease(InputEvent.BUTTON1_MASK);
However, I want the Robot to press the button for a certain period of time. How can I achieve this?
但是，我希望机器人按下按钮一段时间。我怎样才能做到这一点？

Just sleep a bit between the two actions (specified in milliseconds):
只需在两个操作之间稍作睡眠（以毫秒为单位）：
Thread.sleep(long millis);robot.mousePress(InputEvent.BUTTON1_MASK); try { Thread.sleep(1000); } catch(Exception e) {} // Click one second robot.mouseRelease(InputEvent.BUTTON1_MASK);Robot.delay(long millis);robot.mousePress(InputEvent.BUTTON1_MASK); robot.delay(1000); // Click one second robot.mouseRelease(InputEvent.BUTTON1_MASK);
Thread.sleep(long millis);robot.mousePress(InputEvent.BUTTON1_MASK); try { Thread.sleep(1000); } catch(Exception e) {} // Click one second robot.mouseRelease(InputEvent.BUTTON1_MASK);Robot.delay(long millis);robot.mousePress(InputEvent.BUTTON1_MASK); robot.delay(1000); // Click one second robot.mouseRelease(InputEvent.BUTTON1_MASK);

I did that, it's simple: when you detect the mouse is pressed, you save the System.currentTimeMillis(). When you detect the mouse is released, you just check how long it was pressed.
我这样做了，很简单：当你检测到鼠标被按下时，你保存System.currentTimeMillis().当您检测到鼠标被释放时，您只需检查它被按下的时间。
If you want the action to be made after a certain amount of time, even if the mouse is still pressed, you start a thread that lives the desired amount of time when pressed and you interrupt it when releasing. If the thread isn't interrupted in the amount of time you wanted, the action will be performed.
如果您希望在一定时间后执行操作，即使鼠标仍被按下，您也可以启动一个线程，该线程在按下时存活所需的时间，并在释放时中断它。如果线程在您想要的时间内没有被中断，则将执行该操作。
