Android广播接实现电话的监听（电话的状态，拦截）

Android广播接实现电话的监听  

1：需要在AndroidManifest.xml清单中添加权限 

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

2：注册广播 要注意事件的级别 （android中的级别-1000~1000）

<receiver android:name=".PhoneBroadcastReceiver">
<intent-filter android:priority="1000">
<action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
<action android:name="android.intent.action.PHONE_STATE"/>
</intent-filter>
</receiver>

详细配置请看 AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.zyw.broadcastsendsms"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".SendSMS"
            android:label="@string/title_activity_send_sms" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            
        </activity>
        
        <receiver android:name=".PhoneBroadcastReceiver">
            <intent-filter android:priority="1000">
                <action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
                <action android:name="android.intent.action.PHONE_STATE"/>   
            </intent-filter>
        </receiver>
        
    </application>

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

3：编写广播的实现类 这里需要继承BroadcastReceiver 实现onReceive()方法

程序的源代码如下：

package com.zyw.broadcastsendsms;

import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log;

public class PhoneBroadcastReceiver extends BroadcastReceiver {

    private static final String TAG = "message";
    private static boolean mIncomingFlag = false;
    private static String mIncomingNumber = 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)) {
            mIncomingFlag = false;
            String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
            Log.i(TAG, "call OUT:" + phoneNumber);
            
        } else {
            // 如果是来电
            TelephonyManager tManager = (TelephonyManager) context
                    .getSystemService(Service.TELEPHONY_SERVICE);
            switch (tManager.getCallState()) {
            
            case TelephonyManager.CALL_STATE_RINGING:
                mIncomingNumber = intent.getStringExtra("incoming_number");
                Log.i(TAG, "RINGING :" + mIncomingNumber);
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                if (mIncomingFlag) {
                    Log.i(TAG, "incoming ACCEPT :" + mIncomingNumber);
                }
                break;
            case TelephonyManager.CALL_STATE_IDLE:
                if (mIncomingFlag) {
                    Log.i(TAG, "incoming IDLE");
                }
                break;
            }
        }
    }

    
    /*@Override
    public void onReceive(Context context, Intent intent) {
        String number = getResultData();
        if("5556".equals(number)){
            setResultData(null);//挂断
        }else{
            number = "12593"+ number; //其他，则加区号
            setResultData(number);
        }
    }*/
}
