编程方式检测硬件调用presence /挂断键 [英] Programatically detect presence of hardware call/hang up keys

问题描述

我的一个客户想要一个返回boolean值的code方法。如果Android手机硬件有红色/绿色的通话/挂机键真假，如果它不。

One of my clients wants a code method that returns a boolean. True if the Android phone has hardware red/green call/hang up keys and false if it does not.

Sonething是这样的：

Sonething like this :

public void keyFeedbackFromInput(KeyEvent event) {
  if (event.getAction() == KeyEvent.ACTION_DOWN 
        && (event.getFlags() & KeyEvent.FLAG_VIRTUAL_HARD_KEY) != 0) {
    // perform your logic here
  }
}

但不是在一个关键的preSS事件如上面的code片段。他需要确定这个锋线，如果手机有物理红/绿键或虚拟的。

But not in a key press event as in the code snippet above. He needs to determine this up front if a phone has physical red/green keys or virtual ones.

是否有可能，如果是有人可以提供code样品实现这一目标？

Is it possible and if yes can someone provide a code sample to achieve this?

推荐答案

编辑：

有没有调用来获取这些信息后。
您可以尝试具有 Build.MODEL 字典的关键。
是这样的：

There is no call to get that kind of info. You can try having a dictionary with Build.MODEL as key. Something like:

/* Create the dictionary */
private HashMap<String, Boolean> redGreenKeys = new HashMap<String, Boolean>();
redGreenKeys.put("Milestone", false);


public Boolean hasRedGreenButtons() {
    Boolean ret = redGreenKeys.get(Build.MODEL);
    if ( ret == null )
        return false;

    return ret;
}
