Android在电话状态改变是会发送
action为android.intent.action.PHONE_STATE的广播

而拨打电话时会发送
action为android.intent.action.NEW_OUTGOING_CALL的广播
例如：

IntentFilter filter = new IntentFilter();filter.addAction("android.intent.action.NEW_OUTGOING_CALL");filter.addAction("android.intent.action.PHONE_STATE");

-------------------------------------------------
去电时：
* 未接：phone_state=OFFHOOK;
* 挂断：phone_state=IDLE
* 来电时: *
* 未接：phone_state=RINGING
* 已接：phone_state=OFFHOOK;
* 挂断：phone_state=IDLE
-------------------------------------------

JAVA代码

public class PhoneCallReceiver extends BaseReceiver {/**//拨打电话判断及获取号码if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);*/@Overridepublic void onReceive(Context context, Intent intent) {String phone_state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);/*去电时： * 未接：phone_state=OFFHOOK; * 挂断：phone_state=IDLE * 来电时: *  * 未接：phone_state=RINGING * 已接：phone_state=OFFHOOK; * 挂断：phone_state=IDLE**/System.out.println("phone_state======"+phone_state);String incoming_number = intent.getStringExtra("incoming_number");//String incoming_number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER );    String outgoing_number = intent.getStringExtra("android.intent.extra.PHONE_NUMBER");    System.out.println("incoming_number======"+incoming_number);    System.out.println("outgoing_number======"+outgoing_number);    //去电设值    if(outgoing_number!=null && outgoing_number.length()>0){     System.out.println("去电号码"+outgoing_number);        }     //来电设值    if(incoming_number!=null && incoming_number.length()>0){     System.out.println("来电号码"+incoming_number);    }    if (TelephonyManager.EXTRA_STATE_OFFHOOK.equals(phone_state) || TelephonyManager.EXTRA_STATE_RINGING.equals(phone_state)){System.out.println("去电话未接或来电未接及来电已接");}if (TelephonyManager.EXTRA_STATE_IDLE.equals(phone_state)){                    System.out.println("电话已挂断");}return;}}
