TelephonyManager的作用:



用于管理手机通话状态,获取电话信息(设备信息、sim卡信息以及网络信息),

侦听电话状态(呼叫状态服务状态、信号强度状态等)以及能够调用电话拨号器拨打电话!

怎样获得TelephonyManager的服务对象:

TelephonyManager tManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

TelephonyManager的相关使用方法实例:

1.调用拨号器拨打电话号码:

Uri uri=Uri.parse("tel:"+电话号码);
Intent intent=new Intent(Intent.ACTION_DIAL,uri);
startActivity(intent);

ps:调用的是系统的拨号界面哦!

2.获取Sim卡信息与网络信息

执行效果图:(模拟器下获取不了相关信息的哦,这里用的是真机哈!)

Android提供的系统服务之--TelephonyManager(电话管理器)

代码实现流程:

1.定义了一个存储状态名称的array.xml的数组资源文件。

2.布局定义了一个简单的listview,列表项是两个水平方向的textview

3.Activity界面中调用相关方法获得相应參数的值,再把数据绑定到listview上!

具体代码例如以下:

array.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-- 声明一个名为statusNames的字符串数组 -->
<string-array name="statusNames">
<item>设备编号</item>
<item>软件版本号</item>
<item>网络运营商代号</item>
<item>网络运营商名称</item>
<item>手机制式</item>
<item>设备当前位置</item>
<item>SIM卡的国别</item>
<item>SIM卡序列号</item>
<item>SIM卡状态</item>
</string-array>
<!-- 声明一个名为simState的字符串数组 -->
<string-array name="simState">
<item>状态未知</item>
<item>无SIM卡</item>
<item>被PIN加锁</item>
<item>被PUK加锁</item>
<item>被NetWork PIN加锁</item>
<item>已准备好</item>
</string-array>
<!-- 声明一个名为phoneType的字符串数组 -->
<string-array name="phoneType">
<item>未知</item>
<item>GSM</item>
<item>CDMA</item>
</string-array>
</resources>

布局代码例如以下:

activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.jay.example.getphonestatus.MainActivity" > <ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/statuslist" /> </LinearLayout>

line.xml:

<?xml version="1.0" encoding="utf-8"?

>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" > <TextView
android:id="@+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:width="230px"
android:textSize="16dp"
/> <TextView
android:id="@+id/value"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="8px"
android:textSize="16dp"
/> </LinearLayout>

MainActivity.java

package com.jay.example.getphonestatus;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map; import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.widget.ListView;
import android.widget.SimpleAdapter; public class MainActivity extends Activity { //定义一个ListView对象,一个代表状态名称的数组,以及手机状态的集合
private ListView showlist;
private String[] statusNames;
private ArrayList<String> statusValues = new ArrayList<String>(); @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
showlist = (ListView) findViewById(R.id.statuslist); //①获得系统提供的TelphonyManager对象的实例
TelephonyManager tManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); //②获得状态名词的数组,Sim卡状态的数组,电话网络类型的数组
//就是获得array.xml中的相应数组名的值
statusNames = getResources().getStringArray(R.array.statusNames);
String[] simState = getResources().getStringArray(R.array.simState);
String[] phoneType = getResources().getStringArray(R.array.phoneType); //③依照array.xml中的顺序,调用相应的方法,将相应的值保存到集合里
statusValues.add(tManager.getDeviceId()); //获得设备编号
//获取系统平台的版本号
statusValues.add(tManager.getDeviceSoftwareVersion()
!= null? tManager.getDeviceSoftwareVersion():"未知");
statusValues.add(tManager.getNetworkOperator()); //获得网络运营商代号
statusValues.add(tManager.getNetworkOperatorName()); //获得网络运营商的名称
statusValues.add(phoneType[tManager.getPhoneType()]); //获得手机的网络类型
// 获取设备所在位置
statusValues.add(tManager.getCellLocation() != null ? tManager
.getCellLocation().toString() : "未知位置");
statusValues.add(tManager.getSimCountryIso()); // 获取SIM卡的国别
statusValues.add(tManager.getSimSerialNumber()); // 获取SIM卡序列号
statusValues.add(simState[tManager.getSimState()]); // 获取SIM卡状态 //④遍历状态的集合,把状态名与相应的状态加入到集合中
ArrayList<Map<String, String>> status =
new ArrayList<Map<String, String>>();
for (int i = 0; i < statusValues.size(); i++)
{
HashMap<String, String> map = new HashMap<String, String>();
map.put("name", statusNames[i]);
map.put("value", statusValues.get(i));
status.add(map);
}
//⑤使用SimpleAdapter封装List数据
SimpleAdapter adapter = new SimpleAdapter(this, status,
R.layout.line, new String[] { "name", "value" }
, new int[] { R.id.name, R.id.value });
// 为ListView设置Adapter
showlist.setAdapter(adapter);
}
}

最后别忘了,往AndroidManifest.xml文件里加入下述权限哦!

    <!-- 加入訪问手机位置的权限 -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<!-- 加入訪问手机状态的权限 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

3.监听手机的全部来电:

对于监听到的通话记录结果,你能够採取不同的方式获取到,这里用到的是把通话记录写入到文件里,

而你也能够以短信的形式发送给你,或者是上传到某个平台,当然假设通信记录不多的话还能够用短信

多了的话就非常easy给人发现的了。

另外,这里用的是Activity而非Service,就是说要打开这个Activity,才干够进行监听,通常我们的需求都是

要偷偷滴在后台跑的,由于时间关系就不写Service的了,大家自己写写吧,让Service随开机一起启动就可以!

代码解析:

非常easy,事实上就是重写TelephonyManager的一个通话状态监听器PhoneStateListener

然后调用TelephonyManager.listen()的方法进行监听,当来电的时候,

程序就会将来电号码记录到文件里

MainActivity.java:

package com.jay.PhoneMonitor;

import java.io.FileNotFoundException;
import java.io.OutputStream;
import java.io.PrintStream; import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import java.util.Date; public class MainActivity extends Activity
{
TelephonyManager tManager; @Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// 取得TelephonyManager对象
tManager = (TelephonyManager)
getSystemService(Context.TELEPHONY_SERVICE);
// 创建一个通话状态监听器
PhoneStateListener listener = new PhoneStateListener()
{
@Override
public void onCallStateChanged(int state, String number)
{
switch (state)
{
// 无不论什么状态
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
// 来电铃响时
case TelephonyManager.CALL_STATE_RINGING:
OutputStream os = null;
try
{
os = openFileOutput("phoneList", MODE_APPEND);
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
PrintStream ps = new PrintStream(os);
// 将来电号码记录到文件里
ps.println(new Date() + " 来电:" + number);
ps.close();
break;
default:
break;
}
super.onCallStateChanged(state, number);
}
};
// 监听电话通话状态的改变
tManager.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
}
}

当然还须要在AndroidManifest.xml中加入以下的权限:

<!-- 授予该应用读取通话状态的权限 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

执行效果:

注意!要让这个程序位于前台哦!用还有一个电话拨打该电话,接着就能够在DDMS的file Explorer的应用

相应包名的files文件夹下看到phoneList的文件了,我们能够将他导出到电脑中打开,文件的大概内容例如以下:

THR Oct 30 12:05:48 GMT 2014 来电: 137xxxxxxx

4.黑名单来电自己主动挂断:

所谓的黑名单就是将一些电话号码加入到一个集合中,当手机接收到这些电话的时候就直接挂断!

可是Android并没有给我们提供挂断电话的API,于是乎我们须要通过AIDL来调用服务中的API来

实现挂断电话!

于是乎第一步要做的就是把android源代码中的以下两个文件拷贝到src下的对应位置,他们各自是:

com.android.internal.telephony包下的ITelephony.aidl;

android.telephony包下的NeighboringCellInfo.aidl;

要创建相应的包哦!就是要把aidl文件放到上面的包下!!!

接着仅仅须要调用ITelephony的endCall就可以挂断电话!

这里给出的是简单的单个号码的拦截,输入号码,点击屏蔽button后,假设此时屏蔽的电话呼入的话;

直接会挂断,代码还是比較简单的,以下粘一下,由于用的模拟器是Genymotion,所以就不演示

程序执行后的截图了!

MainActivity.java:

package com.jay.example.locklist;

import java.lang.reflect.Method;

import com.android.internal.telephony.ITelephony;

import android.app.Activity;
import android.os.Bundle;
import android.os.IBinder;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText; public class MainActivity extends Activity { private TelephonyManager tManager;
private PhoneStateListener pListener;
private String number;
private EditText locknum;
private Button btnlock; public class PhonecallListener extends PhoneStateListener
{
@Override
public void onCallStateChanged(int state, String incomingNumber) {
switch(state)
{
case TelephonyManager.CALL_STATE_IDLE:break;
case TelephonyManager.CALL_STATE_OFFHOOK:break;
//当有电话拨入时
case TelephonyManager.CALL_STATE_RINGING:
if(isBlock(incomingNumber))
{
try
{
Method method = Class.forName("android.os.ServiceManager")
.getMethod("getService", String.class);
// 获取远程TELEPHONY_SERVICE的IBinder对象的代理
IBinder binder = (IBinder) method.invoke(null,
new Object[] { TELEPHONY_SERVICE });
// 将IBinder对象的代理转换为ITelephony对象
ITelephony telephony = ITelephony.Stub.asInterface(binder);
// 挂断电话
telephony.endCall();
}catch(Exception e){e.printStackTrace();}
}
break;
}
super.onCallStateChanged(state, incomingNumber);
}
} @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); locknum = (EditText) findViewById(R.id.locknum);
btnlock = (Button) findViewById(R.id.btnlock); //获取系统的TelephonyManager管理器
tManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
pListener = new PhoneStateListener();
tManager.listen(pListener, PhoneStateListener.LISTEN_CALL_STATE); btnlock.setOnClickListener(new OnClickListener() { @Override
public void onClick(View v) {
number = locknum.getText().toString();
}
}); } public boolean isBlock(String phone)
{
if(phone.equals(number))return true;
return false;
} }

另外还须要加入下述的权限:

<!-- 授予该应用控制通话的权限 -->
<uses-permission android:name="android.permission.CALL_PHONE" />
<!-- 授予该应用读取通话状态的权限 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

当然,很多其它的时候我们屏蔽的不会仅仅是一个号码,这个时候能够使用集合,把多个要屏蔽的号码加入到

集合中,或者是文件里,这里就直接给出李刚老师的demo,他提供的是一个带复选框的列表供用户

勾选黑名单,这里就不解析了,直接给出代码下载吧!
