Android VOIP呼出中振铃的实现

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

telephonyManager.listen(new PhoneStateListener() {
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        super.onCallStateChanged(state, incomingNumber);
        switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                // 在这里处理振铃状态的逻辑
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                // 在这里处理接听状态的逻辑
                break;
            case TelephonyManager.CALL_STATE_IDLE:
                // 在这里处理空闲状态的逻辑
                break;
        }
    }
}, PhoneStateListener.LISTEN_CALL_STATE);
