DJI SDK中的新DJIKeyManager

Question

在SDK 4.0中，引入了DJIKeyManager，我想知道何时以及如何使用它。

例如，函数

let batteryLevelKey = DJIBatteryKey(param: DJIBatteryParamChargeRemainingInPercent)

keyManager.startListeningForChanges(on: batteryLevelKey!, withListener: self, andUpdate: .... 

DJIKeyManager提供的

看起来与

相同

battery(_ battery: DJIBattery, didUpdate batteryState: DJIBatteryState) 

Answer 1

你喜欢那样

final BatteryKey batterLevelKey = BatteryKey.create(BatteryKey.CHARGE_REMAINING_IN_PERCENT);
    DJISDKManager.getInstance().getKeyManager().addListener(batterLevelKey, new KeyListener() {
        @Override
        public void onValueChange(@Nullable Object o, @Nullable Object o1) {
            int remainingChargeInPercentage = (int) o1;
            Log.d("remainingChargeInPercentage", remainingChargeInPercentage + "");
        }
    });
