我用什么应该是pretty的简单code，但它只是不想要工作。是否OS块拦截呢？

  @覆盖
公共布尔onKeyLong preSS（INT键code，KeyEvent的事件）{


    如果（键code == KeyEvent.KEY code_MENU）
    {
    longOption preSS = TRUE;
    openOptionsMenu（）;
        返回true;
    }
    返回super.onKeyLong preSS（键code，事件）;
}
 

解决方案

您必须调用 startTracking（）从正常的情况下 onKey preSS（）方法：

  @覆盖
公共布尔的onkeydown（INT键code，KeyEvent的事件）{
    如果（键code == KeyEvent.KEY code_MENU）{
        event.startTracking（）;
        返回true;
    }
    返回super.onKeyDown（键code，事件）;
}
 

另请参见a我问的问题与前段时间的回答。

I'm using what should be pretty simple code, but it just doesn't want to work. Does the OS block intercepting this?

@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {


    if (keyCode == KeyEvent.KEYCODE_MENU) 
    {
    longOptionPress = true;
    openOptionsMenu();
        return true;
    }
    return super.onKeyLongPress(keyCode, event);
}

You must call startTracking() on the event from the normal onKeyPress() method:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_MENU) {
        event.startTracking();
        return true;
    }
    return super.onKeyDown(keyCode, event);
}
