如何模拟连续按键

[danielkoo]

在不支持连续按键的手机上如何模拟连续按键呢？用什么方法好呢？
我想应该使用线程把，但不知道具体怎样实现好！

我写的PAINT的部分乱写的，不多实现了重复按键的。你可以参考一下。我也参考了一位网友的游戏。！希望对你有帮助！

谢谢楼上的，之前我自己也实现了连续按键，方法基本上与你的相同。我的方法是不断的销毁和重新生成线程。不过我看了这段代码：public void run()
{
while (true)
{
while (hasRepeat)
{
try
{
PlayG();
Thread.sleep(10);
}
catch (Exception e)
{}
}
}
}
}
让我受益匪浅，此方法好多了！真的十分感激：）

小弟觉得如果是一般应用的话，不一定非要用多线程实现，可以使用类似锁变量的方法至状态的切换，在keypressed时至ture，在keyup时至false。在实际的手机游戏上使用过，感觉还可以
