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);}}}?

通过接收呼出电话的广播来实现
定义广播类
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);//呼出电话if(action.equals(MyBroadcastReceiver.B_ACTION_NEW_OUTGOING_CALL)){String outPhoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);Log.i(TAG, "[Broadcast]ACTION_NEW_OUTGOING_CALL:"+outPhoneNumber);//this.setResultData(null);//这里可以更改呼出电话号码。如果设置为null，电话就永远不会播出了.}}}?
定义activity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_ACTION_NEW_OUTGOING_CALL = Intent.ACTION_NEW_OUTGOING_CALL;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(Intent.ACTION_NEW_OUTGOING_CALL);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);}}?

要监听android打电话和接电话，只需下面2步骤
1.第一步，写一个Receiver继承自BroadcastReceiver
public class PhoneStatReceiver extends BroadcastReceiver{ private static final String TAG = "PhoneStatReceiver"; // private static MyPhoneStateListener phoneListener = new MyPhoneStateListener(); private static boolean incomingFlag = false; private static String incoming_number = null; @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); Log.i(TAG, "call OUT:"+phoneNumber); }else{ //如果是来电 TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE); switch (tm.getCallState()) { case TelephonyManager.CALL_STATE_RINGING: incomingFlag = true;//标识当前是来电 incoming_number = intent.getStringExtra("incoming_number"); Log.i(TAG, "RINGING :"+ incoming_number); break; case TelephonyManager.CALL_STATE_OFFHOOK: if(incomingFlag){ Log.i(TAG, "incoming ACCEPT :"+ incoming_number); } break; case TelephonyManager.CALL_STATE_IDLE: if(incomingFlag){ Log.i(TAG, "incoming IDLE"); } break; } } }}?
第二步：在AndroidManifest.xml，配置写好的Receiver，并拦截相应的BroadCastAction，
另外注意加上相应的权限。
<receiver android:name=".filter.PhoneStatReceiver"> <intent-filter> <action android:name="android.intent.action.PHONE_STATE"/> <action android:name="android.intent.action.NEW_OUTGOING_CALL" /> </intent-filter></receiver><uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission><uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission>
