android 呼出电话的监听（去电监听）

权限：

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

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);}}
