这里主要是总结一下如何监听有未接来电的问题
1.1 使用广播接收器 BrocastReceiver
实现思路 :
静态注册监听android.intent.action.PHONE_STATE 的广播接收器 当手机的状态改变后将会触发 onReceive.
手机的状态分为CALL_STATE_RINGING(响铃中),CALL_STATE_IDLE(空闲),CALL_STATE_OFFHOOK(忙音).
也就是说当你没有任何电话是，状态是 IDLE ，当接到电话时是 OFFHOOK ，电话结束后返回 IDLE 状态。
记录上一次的手机状态,如果的手机现在的空闲,上次的状态响铃中的话,就可以判断是未接来电.

import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.telephony.TelephonyManager; import android.util.Log; import android.widget.Toast; public class PhoneStateReceiver extends BroadcastReceiver { private static int lastCallState = TelephonyManager.CALL_STATE_IDLE; @Override public void onReceive(Context arg0, Intent arg1) { String action = arg1.getAction(); Log.d("PhoneStateReceiver", action ); TelephonyManager telephonyManager = (TelephonyManager) arg0 .getSystemService(Context.TELEPHONY_SERVICE); int currentCallState = telephonyManager.getCallState(); Log.d("PhoneStateReceiver", "currentCallState=" + currentCallState ); if (currentCallState == TelephonyManager.CALL_STATE_IDLE) {// 空闲 //TODO } else if (currentCallState == TelephonyManager.CALL_STATE_RINGING) {// 响铃 //TODO } else if (currentCallState == TelephonyManager.CALL_STATE_OFFHOOK) {// 接听 //TODO } if(lastCallState == TelephonyManager.CALL_STATE_RINGING && currentCallState == TelephonyManager.CALL_STATE_IDLE){ Toast.makeText(arg0, "有未接来电", 1).show(); } lastCallState = currentCallState; } } |
1.2 使用 PhoneStateListener
实现思路 :
继承PhoneStateListener后,当手机的状态改变后将会触发onCallStateChanged.手机的状态分为CALL_STATE_RINGING(响铃中),CALL_STATE_IDLE(空闲),CALL_STATE_OFFHOOK(忙音).
也就是说当你没有任何电话是，状态是 IDLE ，当接到电话时是 OFFHOOK ，电话结束后返回 IDLE 状态。
记录上一次的手机状态,如果的手机现在的空闲,上次的状态响铃中的话,就可以判断是未接来电.
不足:现在的处理不能判断出是用户是否主动不接电话.
