如何在设备呼叫时获得意图？

Question

当设备启动呼叫和结束呼叫时，如何获取我的注册BroadcastReceiver的意图？无论是来电还是来电都没关系。每次设备启动呼叫和结束呼叫时，我只需要获取Intent。

Answer 1

private class PhoneCallListener extends PhoneStateListener {


    @Override
    public void onCallStateChanged(int state, String incomingNumber) {

        if (TelephonyManager.CALL_STATE_RINGING == state) {

        }

        if (TelephonyManager.CALL_STATE_OFFHOOK == state) {

        }

        if (TelephonyManager.CALL_STATE_IDLE == state) {

        }
    }
}

你在onCreate（）上添加：

PhoneCallListener phoneListener = new PhoneCallListener();
TelephonyManager telephonyManager = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(phoneListener,PhoneStateListener.LISTEN_CALL_STATE);
