Android TelephonyManager示例
让我们看一下TelephonyManager的简单示例，该示例显示电话服务的信息。
activity_main.xml从面板上拖动一个textview，现在xml文件将如下所示。

< RelativeLayout xmlns:androclass="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" >< TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_marginLeft="38dp" android:layout_marginTop="30dp" android:text="Phone Details:" />< /RelativeLayout>

活动类现在，编写代码以显示有关电话服务的信息。

package com.srcmini.telephonymanager; import android.os.Bundle; import android.app.Activity; import android.content.Context; import android.telephony.TelephonyManager; import android.view.Menu; import android.widget.TextView; public class MainActivity extends Activity { TextView textView1; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); textView1=(TextView)findViewById(R.id.textView1); //Get the instance of TelephonyManager TelephonyManagertm=(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE); //Calling the methods of TelephonyManager the returns the information String IMEINumber=tm.getDeviceId(); String subscriberID=tm.getDeviceId(); String SIMSerialNumber=tm.getSimSerialNumber(); String networkCountryISO=tm.getNetworkCountryIso(); String SIMCountryISO=tm.getSimCountryIso(); String softwareVersion=tm.getDeviceSoftwareVersion(); String voiceMailNumber=tm.getVoiceMailNumber(); //Get the phone type String strphoneType=""; int phoneType=tm.getPhoneType(); switch (phoneType) { case (TelephonyManager.PHONE_TYPE_CDMA): strphoneType="CDMA"; break; case (TelephonyManager.PHONE_TYPE_GSM): strphoneType="GSM"; break; case (TelephonyManager.PHONE_TYPE_NONE): strphoneType="NONE"; break; }//getting information if phone is in roaming boolean isRoaming=tm.isNetworkRoaming(); String info="Phone Details:\n"; info+="\n IMEI Number:"+IMEINumber; info+="\n SubscriberID:"+subscriberID; info+="\n Sim Serial Number:"+SIMSerialNumber; info+="\n Network Country ISO:"+networkCountryISO; info+="\n SIM Country ISO:"+SIMCountryISO; info+="\n Software Version:"+softwareVersion; info+="\n Voice Mail Number:"+voiceMailNumber; info+="\n Phone Network Type:"+strphoneType; info+="\n In Roaming? :"+isRoaming; textView1.setText(info); //displaying the information in the textView }}

AndroidManifest.xml【android电话管理器教程】你需要在AndroidManifest.xml文件中提供READ_PHONE_STATE权限。

< ?xml version="1.0" encoding="utf-8"?> < manifest xmlns:androclass="http://schemas.android.com/apk/res/android" package="com.srcmini.telephonymanager" android:versionCode="1" android:versionName="1.0" >< uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" />< uses-permission android:name="android.permission.READ_PHONE_STATE"/> < application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > < activity android:name="com.srcmini.telephonymanager.MainActivity" android:label="@string/app_name" > < intent-filter> < action android:name="android.intent.action.MAIN" />< category android:name="android.intent.category.LAUNCHER" /> < /intent-filter> < /activity> < /application>< /manifest>
