Android自动接听和挂断电话实现原理:http://blog.csdn.net/chenda_lin/article/details/41346493
Android提供的系统服务之--TelephonyManager(电话管理器):http://www.2cto.com/kf/201410/347844.html
android 实现来电自动接听和自动挂断的方法:
第一步:准备应用环境需要的系统包和aidl文件。
(1)在应用中创建包:android.telephony
将android系统框架下的\framework\telephony\java\android\telephony目录中的NeighboringCellInfo.aidl文件复制到上面创建的包(android.telephony )中;
(2)在应用中创建包:com.android.internal.telephony
将
android系统框架下的\framework\telephony\java\com\android\internal\telephony目录中
的ITelephony.aidl文件复制到上面创建的包(com.android.internal.telephony )中。
第二步:创建一个获取ITelephony的方法
PhoneUtils.java
package com.zhouzijing.android.demo;
import java.lang.reflect.Method;
import com.android.internal.telephony.ITelephony;
import android.telephony.TelephonyManager;
public class PhoneUtils {
/**
* 根据传入的TelephonyManager来取得系统的ITelephony实例.
* @param telephony
* @return 系统的ITelephony实例
* @throws Exception
*/
public static ITelephony getITelephony(TelephonyManager telephony) throws Exception {
Method getITelephonyMethod = telephony.getClass().getDeclaredMethod("getITelephony");
getITelephonyMethod.setAccessible(true);//私有化函数也能使用
return (ITelephony)getITelephonyMethod.invoke(telephony);
}
}
第三步:创建电话广播拦截器
MyPhoneBroadcastReceiver.java
package com.zhouzijing.android.demo;
import com.android.internal.telephony.ITelephony;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log;
public class MyPhoneBroadcastReceiver extends BroadcastReceiver {
private final static String TAG = MyPhone.TAG;
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
Log.i(TAG, "[Broadcast]"+action);
//呼入电话
if(action.equals(MyPhone.B_PHONE_STATE)){
Log.i(TAG, "[Broadcast]PHONE_STATE");
doReceivePhone(context,intent);
}
}
/**
* 处理电话广播.
* @param context
* @param intent
*/
public void doReceivePhone(Context context, Intent intent) {
String phoneNumber = intent.getStringExtra(
TelephonyManager.EXTRA_INCOMING_NUMBER);
TelephonyManager telephony = (TelephonyManager)context.getSystemService(
Context.TELEPHONY_SERVICE);
int state = telephony.getCallState();
switch(state){
case TelephonyManager.CALL_STATE_RINGING:
Log.i(TAG, "[Broadcast]等待接电话="+phoneNumber);
try {
ITelephony iTelephony = PhoneUtils.getITelephony(telephony);
iTelephony.answerRingingCall();//自动接通电话
//iTelephony.endCall();//自动挂断电话
} catch (Exception e) {
Log.e(TAG, "[Broadcast]Exception="+e.getMessage(), e);
}
break;
case TelephonyManager.CALL_STATE_IDLE:
Log.i(TAG, "[Broadcast]电话挂断="+phoneNumber);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.i(TAG, "[Broadcast]通话中="+phoneNumber);
break;
}
}
}
第四部:注册电话广播拦截器
MyPhone.java
package com.zhouzijing.android.demo;
import android.app.Activity;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.View;
public class MyPhone extends Activity {
public final static String TAG = "MyPhone";
public final static String B_PHONE_STATE = TelephonyManager.ACTION_PHONE_STATE_CHANGED;
private MyPhoneBroadcastReceiver mBroadcastReceiver;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_phone);
}
//按钮1-注册广播
public void registerThis(View v) {
Log.i(TAG, "registerThis");
mBroadcastReceiver = new MyPhoneBroadcastReceiver();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(B_PHONE_STATE);
intentFilter.setPriority(Integer.MAX_VALUE);
registerReceiver(mBroadcastReceiver, intentFilter);
}
//按钮2-撤销广播
public void unregisterThis(View v) {
Log.i(TAG, "unregisterThis");
unregisterReceiver(mBroadcastReceiver);
}
}
第5步:在AndroidManifest.xml配置权限
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />
<uses-permission android:name="android.permission.CALL_PHONE"/>
其中:
iTelephony.answerRingingCall();//自动接通电话
必须有权限 android.permission.MODIFY_PHONE_STATE
iTelephony.endCall();//自动挂断电话
必须有权限 android.permission.CALL_PHONE。
添加权限<uses-permission android:name="android.permission.CALL_PHONE"/><uses-permission android:name="android.permission.MODIFY_PHONE_STATE"/> main.xml<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas。android。com/apk/res/android" androidrientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <RadioGroup android:layout_height="wrap_content" android:layout_width="fill_parent" android:id="@+id/rGrpSelect"> <RadioButton android:layout_height="wrap_content" android:layout_width="fill_parent" android:id="@+id/rbtnAutoAccept" android:text="所有来电自动接听"></RadioButton> <RadioButton android:layout_height="wrap_content" android:layout_width="fill_parent" android:id="@+id/rbtnAutoReject" android:text="所有来电自动挂断"></RadioButton> </RadioGroup> <ToggleButton android:layout_height="wrap_content" android:layout_width="fill_parent" android:id="@+id/tbtnRadioSwitch" android:textOn="Radio已经启动" android:textOff="Radio已经关闭" android:textSize="24dip" android:textStyle="normal"></ToggleButton> <ToggleButton android:layout_height="wrap_content" android:layout_width="fill_parent" android:id="@+id/tbtnDataConn" android:textSize="24dip" android:textStyle="normal" android:textOn="允许数据连接" android:textOff="禁止数据连接"></ToggleButton> </LinearLayout> PhoneUtils.java是手机功能类,从TelephonyManager中实例化ITelephony并返回,源码如下:package com.testTelephony; import java.lang.reflect.Field; import java.lang.reflect.Method; import com.android.internal.telephony.ITelephony; import android.telephony.TelephonyManager; import android.util.Log; public class PhoneUtils { /** * 从TelephonyManager中实例化ITelephony,并返回 */ static public 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 (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.getName()); } // 取得所有常量 Field[] allFields = clsShow.getFields(); for (i = 0; i < allFields.length; i++) { Log.e("Field name", allFields.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(); } } } testTelephony.java是主类,使用PhoneStateListener监听通话状态,以及实现上述4种电话控制功能,源码如下:package com.testTelephony; import android.app.Activity; import android.os.Bundle; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; import android.util.Log; import android.view.View; import android.widget.RadioGroup; import android.widget.ToggleButton; public class testTelephony extends Activity { /** Called when the activity is first created. */ RadioGroup rg;//来电操作单选框 ToggleButton tbtnRadioSwitch;//Radio开关 ToggleButton tbtnDataConn;//数据连接的开关 TelephonyManager telMgr; CallStateListener stateListner; int checkedId=0; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); telMgr= (TelephonyManager)getSystemService(TELEPHONY_SERVICE); telMgr.listen(new CallStateListener(), CallStateListener.LISTEN_CALL_STATE); PhoneUtils.printAllInform(TelephonyManager.class); rg = (RadioGroup)findViewById(R.id.rGrpSelect); rg.setOnCheckedChangeListener(new CheckEvent()); tbtnRadioSwitch=(ToggleButton)this.findViewById(R.id.tbtnRadioSwitch); tbtnRadioSwitch.setOnClickListener(new ClickEvent()); try { tbtnRadioSwitch.setChecked(PhoneUtils.getITelephony(telMgr).isRadioOn()); } catch (Exception e) { Log.e("error",e.getMessage()); } tbtnDataConn=(ToggleButton)this.findViewById(R.id.tbtnDataConn); tbtnDataConn.setOnClickListener(new ClickEvent()); try { tbtnDataConn.setChecked(PhoneUtils.getITelephony(telMgr).isDataConnectivityPossible()); } catch (Exception e) { Log.e("error",e.getMessage()); } } /** * 来电时的操作 * @author GV * */ public class CheckEvent implements RadioGroup.OnCheckedChangeListener{ @Override public void onCheckedChanged(RadioGroup group, int checkedId) { testTelephony.this.checkedId=checkedId; } } /** * Radio和数据连接的开关 * @author GV * */ public class ClickEvent implements View.OnClickListener{ @Override public void onClick(View v) { if (v == tbtnRadioSwitch) { try { PhoneUtils.getITelephony(telMgr).setRadio(tbtnRadioSwitch.isChecked()); } catch (Exception e) { Log.e("error", e.getMessage()); } } else if(v==tbtnDataConn){ try { if(tbtnDataConn.isChecked()) PhoneUtils.getITelephony(telMgr).enableDataConnectivity(); else if(!tbtnDataConn.isChecked()) PhoneUtils.getITelephony(telMgr).disableDataConnectivity(); } catch (Exception e) { Log.e("error", e.getMessage()); } } } } /** * 监视电话状态 * @author GV * */ public class CallStateListener extends PhoneStateListener { @Override public void onCallStateChanged(int state, String incomingNumber) { if(state==TelephonyManager.CALL_STATE_IDLE)//挂断 { Log.e("IDLE",incomingNumber); } else if(state==TelephonyManager.CALL_STATE_OFFHOOK)//接听 { Log.e("OFFHOOK",incomingNumber); } else if(state==TelephonyManager.CALL_STATE_RINGING)//来电 { if(testTelephony.this.checkedId==R.id.rbtnAutoAccept) { try { //需要<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" /> PhoneUtils.getITelephony(telMgr).silenceRinger();//静铃 PhoneUtils.getITelephony(telMgr).answerRingingCall();//自动接听 } catch (Exception e) { Log.e("error",e.getMessage()); } } else if(testTelephony.this.checkedId==R.id.rbtnAutoReject) { try { PhoneUtils.getITelephony(telMgr).endCall();//挂断 PhoneUtils.getITelephony(telMgr).cancelMissedCallsNotification();//取消未接显示 } catch (Exception e) { Log.e("error",e.getMessage()); } } } super.onCallStateChanged(state, incomingNumber); } } }
