Question

类型getSystemService(String)

的方法BluetoothDevice未定义

在我的手机上访问我的SIM卡的CLASS TelephonyInfo正在运行

我想用它来显示我连接的设备上的SIM卡详细信息，我做了一些更改以包含蓝牙，但我遇到了methodgetSystemService的问题方法getSystemService(String)未定义类型BluetoothDevice，我发现了一些类似的问题，但没有人使用蓝牙，我尝试了他们的解决方案，但由于我使用蓝牙，它没有用。这是我做了一些更改之后的代码

我正在使用这个类来显示我所连接的蓝牙设备的Sim细节，我有班级TelephonyInfo

public final class TelephonyInfo {

    private static TelephonyInfo telephonyInfo;

         TelephonyInfo.imeiSIM1 = imeiSIM1;

        return imeiSIM2;

有人可以帮我解决这个问题吗？

Answer 1

getSystemService（）是上下文类的方法，因此您需要在上下文中运行它。

您复制它的原始代码可能是从 Activity 派生的类中运行的。如果它不在活动中，您需要将上下文参数传递给您的方法。
