android - 如何在android中检查sim是否处于活动状态

Question

请告诉我他们是否有任何方法可以检查 sim 是否处于活动状态。我知道我可以通过使用电话管理器来做到这一点，但我不知道哪种电话管理器方法有帮助。我尝试了很多，但没有得到想要的结果。

Answer 1

试试这个来检测sim是否可用

TelephonyManager telMgr = (TelephonyManager)     getSystemService(Context.TELEPHONY_SERVICE);
int simState = telMgr.getSimState();
        switch (simState) {
            case TelephonyManager.SIM_STATE_ABSENT:
                // do something
                break;
            case TelephonyManager.SIM_STATE_NETWORK_LOCKED:
                // do something
                break;
            case TelephonyManager.SIM_STATE_PIN_REQUIRED:
                // do something
                break;
            case TelephonyManager.SIM_STATE_PUK_REQUIRED:
                // do something
                break;
            case TelephonyManager.SIM_STATE_READY:
                // do something
                break;
            case TelephonyManager.SIM_STATE_UNKNOWN:
                // do something
                break;
        }

这样做。。

TelephonyManager telMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    int simState = telMgr.getSimState();
            switch (simState) {
                case TelephonyManager.SIM_STATE_ABSENT:
                    // do something
                    break;
                case TelephonyManager.SIM_STATE_NETWORK_LOCKED:
                    // do something
                    break;
                case TelephonyManager.SIM_STATE_PIN_REQUIRED:
                    // do something
                    break;
                case TelephonyManager.SIM_STATE_PUK_REQUIRED:
                    // do something
                    break;
                case TelephonyManager.SIM_STATE_READY:
                    // do something
                    break;
                case TelephonyManager.SIM_STATE_UNKNOWN:
                    // do something
                    break;
            }
