android 呼入电话的监听（来电监听）

android 呼入电话的监听（来电监听）

?

?

需要权限：

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

?

?

方式一：通过广播接收来电

?

定义来电广播接收类

?

package com.zhouzijing.android.demo;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.telephony.TelephonyManager;import android.util.Log;public class BroadcastReceiverMgr extends BroadcastReceiver {private final String TAG = MyBroadcastReceiver.TAG;@Overridepublic void onReceive(Context context, Intent intent) {String action = intent.getAction();Log.i(TAG, "[Broadcast]"+action);//呼入电话if(action.equals(MyBroadcastReceiver.B_PHONE_STATE)){Log.i(TAG, "[Broadcast]PHONE_STATE");doReceivePhone(context,intent);}}/** * 处理电话广播. * @param context * @param intent */public void doReceivePhone(Context context, Intent intent) {String phoneNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);int state = telephony.getCallState();switch(state){case TelephonyManager.CALL_STATE_RINGING:Log.i(TAG, "[Broadcast]等待接电话="+phoneNumber);break;case TelephonyManager.CALL_STATE_IDLE:Log.i(TAG, "[Broadcast]电话挂断="+phoneNumber);break;case TelephonyManager.CALL_STATE_OFFHOOK:Log.i(TAG, "[Broadcast]通话中="+phoneNumber);break;}}}

定义Actitvity类

package com.zhouzijing.android.demo;import android.app.Activity;import android.content.Context;import android.content.Intent;import android.content.IntentFilter;import android.os.Bundle;import android.telephony.PhoneStateListener;import android.telephony.TelephonyManager;import android.util.Log;import android.view.View;public class MyBroadcastReceiver extends Activity {public final static String TAG = "MyBroadcastReceiver";public final static String B_PHONE_STATE = TelephonyManager.ACTION_PHONE_STATE_CHANGED;private BroadcastReceiverMgr mBroadcastReceiver;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.my_broadcast_receiver);}//按钮1-注册广播public void registerIt(View v) {Log.i(TAG, "registerIt");mBroadcastReceiver = new BroadcastReceiverMgr();IntentFilter intentFilter = new IntentFilter();intentFilter.addAction(B_PHONE_STATE);intentFilter.setPriority(Integer.MAX_VALUE);registerReceiver(mBroadcastReceiver, intentFilter);}//按钮2-撤销广播public void unregisterIt(View v) {Log.i(TAG, "unregisterIt");unregisterReceiver(mBroadcastReceiver);}}

方式二：通过监听器来实现

?

package com.zhouzijing.android.demo;import android.app.Activity;import android.content.Context;import android.content.Intent;import android.content.IntentFilter;import android.os.Bundle;import android.telephony.PhoneStateListener;import android.telephony.TelephonyManager;import android.util.Log;import android.view.View;public class MyBroadcastReceiver extends Activity {public final static String TAG = "MyBroadcastReceiver";@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.my_broadcast_receiver);}/** * 按钮-监听电话 * @param v */public void createPhoneListener(View v) {TelephonyManager telephony = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);telephony.listen(new OnePhoneStateListener(),PhoneStateListener.LISTEN_CALL_STATE);}/** * 电话状态监听. * @author stephen * */class OnePhoneStateListener extends PhoneStateListener{@Overridepublic void onCallStateChanged(int state, String incomingNumber) {Log.i(TAG, "[Listener]电话号码:"+incomingNumber);switch(state){case TelephonyManager.CALL_STATE_RINGING:Log.i(TAG, "[Listener]等待接电话:"+incomingNumber);break;case TelephonyManager.CALL_STATE_IDLE:Log.i(TAG, "[Listener]电话挂断:"+incomingNumber);break;case TelephonyManager.CALL_STATE_OFFHOOK:Log.i(TAG, "[Listener]通话中:"+incomingNumber);break;}super.onCallStateChanged(state, incomingNumber);}}}
