TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);

receiver：

private BroadcastReceiver mPhoneStateReceiver = new BroadcastReceiver() {          @Override      public void onReceive(Context context, Intent intent) {                      TelephonyManager tm =                           (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);                                                LogUtil.d(TAG, "phone state: " + tm.getCallState());                    switch (tm.getCallState()) {                       case TelephonyManager.CALL_STATE_IDLE:                       if(mLossOfFocusDuringGainDelay == true && mHasAudioFocusWhenCall){                               int delay = 0;                               mLossOfFocusDuringGainDelay = false;                               mMediaplayerHandler.sendMessageDelayed(                                       mMediaplayerHandler.obtainMessage(FOCUSCHANGE, AudioManager.AUDIOFOCUS_GAIN, 0), delay);                       }                       mHasAudioFocusWhenCall = false;                       break;                    }       }  } ;

 private void registerPhoneStateReceiver(){    registerReceiver(mPhoneStateReceiver, new IntentFilter("android.intent.action.PHONE_STATE"));    }

还有一个permission：

//状态阅读和去电准许

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />

来电的三种状态：

/** Device call state: No activity. */    public static final int CALL_STATE_IDLE = 0;    /** Device call state: Ringing. A new call arrived and is     *  ringing or waiting. In the latter case, another call is     *  already active. */    public static final int CALL_STATE_RINGING = 1;    /** Device call state: Off-hook. At least one call exists      * that is dialing, active, or on hold, and no calls are ringing      * or waiting. */    public static final int CALL_STATE_OFFHOOK = 2;

CALL_STATE_IDLE：空闲状态，就是没有挂掉电话的状态

CALL_STATE_RINGING：响铃状态

CALL_STATE_OFFHOOK：通话状态。就是已经再对话了。

去电广播：

Intent.ACTION_NEW_OUTGOING_CALL

具体的状态不知道，也找不到，可能和来电的state共用吧。
