检测home键preSS的机器人 [英] Detect home button press in android

问题描述

这是我发疯了一段时间了。

This has been driving me nuts for a while now.

有什么办法可靠地检测，如果home键一直pssed在Android应用程序$ P $？

Is there any way of reliably detecting if the home button has been pressed in an android application?

如果做不到这一点，有没有告诉什么原因造成的活动进入的onPause的一条有效的途径？也就是说，我们可以发现，如果它是一个新的活动启动或pressing回引起/家。

Failing that, is there a robust way of telling what caused an activity to go into onPause? i.e Can we detect if it was caused by a new activity launching or by pressing back/home.

我看到一个建议是重写的onPause（），并调用isFinishing（），但是当pressing home键只是因为它会如果一个新的活动已经开始这样失败的区分两者，这将返回false

One suggestion I have seen is to override onPause() and call isFinishing() but this will return false when pressing the home button just as it would if a new activity is starting so this fails to distinguish between the two.

任何帮助非常AP preciated。

Any help much appreciated.

Overiding下面的方法：

Overiding the following method:

@Override
public void onAttachedToWindow() {
    super.onAttachedToWindow();
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);           
}

那么下面的事件将被解雇的home键presses：

Then the following event WILL get fired for home button presses:

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

    if(keyCode == KeyEvent.KEYCODE_HOME)
    {
       //The Code Want to Perform. 
    }
});

我不知道是否有任何副作用这一行：

I'm not sure if there are any side effects with this line:

this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);   

因此​​，它似乎是流行的看法相反，你其实可以听出来home键。令人担忧的是，你可以返回false，并有家庭什么也干不了。

So it would seem that contrary to popular belief, you can in fact listen out for the home key. Worryingly, you can return false and have the home key do nothing.

更新的： 正如预期的那样，有一些副作用影响这一点 - 它似乎嵌入视频和谷歌地图不启用该模式中可见

Update: As expected, there are some side affects with this - it seems that embedded videos and google maps are not visible with this mode enabled.

更新的： 据说这个黑客无法再正常工作为Android 4.0的起的。

Update: Supposedly this hack no longer works as of Android 4.0 onwards
