Android-->电话广播的监听

1:AndroidManifest.xml 注册广播

    
        //主动打电话时,发送的广播
        
        //电话状态改变时,发送的广播 (振铃,挂断,接通)
        
    

2:onReceive

@Override
public void onReceive(Context context, Intent intent) {
    log.info("收到电话广播:{}", intent == null ? "null" : intent.getAction());

    // 如果是拨打电话
    if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
        //拨打电话会优先,收到此广播. 再收到 android.intent.action.PHONE_STATE 的 TelephonyManager.CALL_STATE_OFFHOOK 状态广播;

        String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
        log.info("call OUT:{}", phoneNumber);//获取拨打的手机号码
    } else {
        // 如果是来电
        TelephonyManager tManager = (TelephonyManager) context
                .getSystemService(Service.TELEPHONY_SERVICE);
        //电话的状态
        switch (tManager.getCallState()) {
            case TelephonyManager.CALL_STATE_RINGING:
                //等待接听状态
                mIncomingNumber = intent.getStringExtra("incoming_number");
                log.info("RINGING :" + mIncomingNumber);
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                //接听状态
                break;
            case TelephonyManager.CALL_STATE_IDLE:
                //挂断状态
                break;
        }
    }
}

如果需要挂断电话参考: (可以模拟耳机线上的接听和挂断广播, 实现相应的功能.)
