Android - 判斷SIM卡狀態

Android判斷SIM卡狀態, 是否插入SIM卡.
例如: 根據SIM判斷優先使用的網路類型.

SIM卡狀態

    /**     * 判斷是否包含SIM卡     *     * @return 狀態     */    public static boolean hasSimCard() {        Context context = App.getAppContext();        TelephonyManager telMgr = (TelephonyManager)                context.getSystemService(Context.TELEPHONY_SERVICE);        int simState = telMgr.getSimState();        boolean result = true;        switch (simState) {            case TelephonyManager.SIM_STATE_ABSENT:                result = false; // 沒有SIM卡                break;            case TelephonyManager.SIM_STATE_UNKNOWN:                result = false;                break;        }        Log.d(TAG, result ? 有SIM卡 : 無SIM卡);        return result;    }

全部狀態

        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;        }
