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);
}
}*/
}
