使用Xamarin Android检测电池充满时的设备

Question

我需要检测设备是否安装在底座上(例如，将设备放到充电器支架上)。

下面的代码在大多数情况下都可以工作，但当电池已满并且调用了CradleMonitorService(构造函数时，它就不能工作了。

public class CradleMonitorService
    {
        public CradleMonitorService()
        {
            IsCradled = Battery.State == BatteryState.Charging; 
            Battery.BatteryInfoChanged += Battery_BatteryInfoChanged;
        }

        public bool IsCradled { get; private set; }

        private void Battery_BatteryInfoChanged(object sender, BatteryInfoChangedEventArgs e)
        {
            IsCradled = (e.PowerSource == BatteryPowerSource.AC || e.PowerSource == BatteryPowerSource.Usb);
        }
    }

有什么解决方案吗？

Answer 1

请改用Battery.PowerSource进行检测。

  public CradleMonitorService()
        {
            IsCradled = Battery.PowerSource == BatteryPowerSource.AC || Battery.PowerSource  == BatteryPowerSource.Usb
            Battery.BatteryInfoChanged += Battery_BatteryInfoChanged;
        }
