安卓：为什么PhoneCallListener还活着，活动结束后？ [英] Android : why PhoneCallListener still alive after activity finish?

问题描述

在我的活动，但我完成活动后使用电话监听器的IM，AFER用户拨打一个电话，我的电话监听器没有死，再次布里格后续活动！请帮助我。

  phoneListener =新PhoneCallListener（）;
telephonyManager =（TelephonyManager）
            TransferActivity.this.getSystemService（Context.TELEPHONY_SERVICE）;
telephonyManager.listen（phoneListener，PhoneStateListener.LISTEN_CALL_STATE）;
 

PhoneCallListener类：

 私有类PhoneCallListener扩展PhoneStateListener {
    布尔isPhoneCalling = FALSE;
    @覆盖
    公共无效onCallStateChanged（INT状态，串incomingNumber）{

        如果（TelephonyManager.CALL_STATE_RINGING ==州）{
        }
        如果（TelephonyManager.CALL_STATE_OFFHOOK ==州）{
            isPhoneCalling = TRUE;
        }
        如果（TelephonyManager.CALL_STATE_IDLE ==州）{
            如果（isPhoneCalling）{
                isPhoneCalling = FALSE;
                    意向意图= getIntent（）;
                    startActivity（意向）;
                }
            }
        }
    }
}
 

解决方案

该文件说：

要注销侦听，通过侦听器对象，并设置事件参数LISTEN_NONE（0）。

To unregister a listener, pass the listener object and set the events argument to LISTEN_NONE (0).
