1、首先在manifest中加入如下的权限
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" >
</uses-permission>
<uses-permission android:name="android.permission.CALL_PHONE" >
</uses-permission>
红色的部分如果报错，则clean一下就好了。
<activity
android:name="com.example.tel.phonecall.PhoneCall"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.tel.phonecall.ShowAct"
android:launchMode="singleInstance" >
</activity>
<receiver
android:name="com.example.tel.phonecall.PhoneListener"
android:permission="android.permission.PROCESS_OUTGOING_CALLS" >
<intent-filter android:priority="-1000" >
<action android:name="android.intent.action.PHONE_STATE" >
</action>
<category android:name="android.intent.category.DEFAULT" >
</category>
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" >
</action>
<category android:name="android.intent.category.DEFAULT" >
</category>
</intent-filter>
</receiver>
2、代码如下：

+ " act:" + action);
Toast toast = Toast.makeText(context, "", Toast.LENGTH_SHORT);
if (action.equals("android.intent.action.NEW_OUTGOING_CALL")) {
toast.setText("Outgoing");
} else {
toast.setText("InComing");
TelephonyManager tm = (TelephonyManager) context
.getSystemService(Service.TELEPHONY_SERVICE);
boolean incomingFlag = false;
String incoming_number = "";
switch (tm.getCallState()) {

incomingFlag = true;// 标识当前是来电
incoming_number = intent.getStringExtra("incoming_number");
Log.i(this.getClass().getName(), "RINGING :" + incoming_number);
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
Intent tmpI = new Intent(context, ShowAct.class);
tmpI.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(tmpI);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
if (incomingFlag) {
Log.i(this.getClass().getName(), "incoming ACCEPT :"
+ incoming_number);
}
break;

if (incomingFlag) {
Log.i(this.getClass().getName(), "incoming IDLE");
}
break;
}
}
toast.show();
}
}

if (android.os.Build.VERSION.SDK_INT >= 15) {
Intent meidaButtonIntent = new Intent(

3、ITelephony.aidl
package com.android.internal.telephony;
interface ITelephony {
boolean endCall();
void answerRingingCall();
}
