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    String SYSTEM_REASON = "reason";      String SYSTEM_HOME_KEY = "homekey";      String RECENT_APPS = "recentapps";             @Override      public void onReceive(Context context, Intent intent) {      Tools.log(TAG, "mHomeKeyEventReceiver   onReceive ");    if (mScreenService.isSavingPicture) {    Tools.log(TAG, "mHomeKeyEventReceiver   onReceive   mScreenService.isSavingPicture==true  now return");    return;}        String action = intent.getAction();          Tools.log(TAG, "  intent.getAction(); =====" + intent.getAction());        if (action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {              String reason = intent.getStringExtra(SYSTEM_REASON);              Tools.log(TAG, "   intent.getStringExtra(SYSTEM_REASON) == " + intent.getStringExtra(SYSTEM_REASON));            if (TextUtils.equals(reason, SYSTEM_HOME_KEY)) {                   //表示按了home键,程序到了后台              Tools.log(TAG, "mHomeKeyEventReceiver onReceive Home clicked  stopSelfBySelf");                mScreenService.stopSelfBySelf();            }else if (TextUtils.equals(reason, RECENT_APPS)) {            Tools.log(TAG, "mHomeKeyEventReceiver onReceive recent apps  clicked   stopSelfBySelf");                mScreenService.stopSelfBySelf();}        }       }  }; public static BroadcastReceiver PhoneStatReceiver = new BroadcastReceiver() {          @Override      public void onReceive(Context context, Intent intent) {              //如果是拨打电话              if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){                          //                    incomingFlag = false;                      String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);                                              }else{                                              //如果是来电                      TelephonyManager tm =                           (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);                                                                    switch (tm.getCallState()) {                    case TelephonyManager.CALL_STATE_RINGING:                      if (mScreenService.isSavingPicture) {                    Tools.log(TAG, "phoneStatReceiver call is comming  mScreenService.isSavingPicture=="+mScreenService.isSavingPicture);                    return;                    }                    Tools.log(TAG, "phoneStatReceiver call is comming stopSelfBySelf");                    mScreenService.stopSelfBySelf();                    }               }      }  } ;

熄屏监听：这个只能动态注册才能接收到
