方式一：通過廣播接收來電

定義來電廣播接收類

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;    @Override    public void onReceive(Context context, Intent intent) {        String action = intent.getAction();        Log.i(TAG, "[Broadcast]"+action);                //呼入電話        if(action.equals(MyBroadcastReceiver.B_PHONE_STATE)){            Log.i(TAG, "[Broadcast]PHONE_STATE");            doReceivePhone(context,intent);        }    }        /**     * 處理電話廣播.     * @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]等待接電話="+phoneNumber);            break;        case TelephonyManager.CALL_STATE_IDLE:            Log.i(TAG, "[Broadcast]電話掛斷="+phoneNumber);            break;        case TelephonyManager.CALL_STATE_OFFHOOK:            Log.i(TAG, "[Broadcast]通話中="+phoneNumber);            break;        }    }}

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;        @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.my_broadcast_receiver);    }        //按鈕1-註冊廣播    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);    }        //按鈕2-撤銷廣播    public void unregisterIt(View v) {        Log.i(TAG, "unregisterIt");        unregisterReceiver(mBroadcastReceiver);    }    }

方式二：通過監聽器來實現

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";        @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.my_broadcast_receiver);    }        /**     * 按鈕-監聽電話     * @param v     */    public void createPhoneListener(View v) {        TelephonyManager telephony = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);        telephony.listen(new OnePhoneStateListener(),PhoneStateListener.LISTEN_CALL_STATE);    }        /**     * 電話狀態監聽.     * @author stephen     *     */    class OnePhoneStateListener extends PhoneStateListener{        @Override        public void onCallStateChanged(int state, String incomingNumber) {            Log.i(TAG, "[Listener]電話號碼:"+incomingNumber);            switch(state){            case TelephonyManager.CALL_STATE_RINGING:                Log.i(TAG, "[Listener]等待接電話:"+incomingNumber);                break;            case TelephonyManager.CALL_STATE_IDLE:                Log.i(TAG, "[Listener]電話掛斷:"+incomingNumber);                break;            case TelephonyManager.CALL_STATE_OFFHOOK:                Log.i(TAG, "[Listener]通話中:"+incomingNumber);                break;            }            super.onCallStateChanged(state, incomingNumber);        }    }            }
