按键监听

home键：

public static BroadcastReceiver mHomeKeyEventReceiver = new BroadcastReceiver() {  //监听home键，如果按了home键则退出长截屏模式

熄屏监听：这个只能动态注册才能接收到

/**
     * Broadcast Action: Sent when the device goes to sleep and becomes non-interactive.
     * 

     * For historical reasons, the name of this broadcast action refers to the power
     * state of the screen but it is actually sent in response to changes in the
     * overall interactive state of the device.
     * 

     * This broadcast is sent when the device becomes non-interactive which may have
     * nothing to do with the screen turning off.  To determine the
     * actual state of the screen, use {@link android.view.Display#getState}.
     * 

     * See {@link android.os.PowerManager#isInteractive} for details.
     * 
     * You cannot receive this through components declared in
     * manifests, only by explicitly registering for it with
     * {@link Context#registerReceiver(BroadcastReceiver, IntentFilter)
     * Context.registerReceiver()}.
     *
     * 
This is a protected intent that can only be sent
     * by the system.
