android - 解码电池值

Question

在电池的广播接收器中，我有以下 3 行代码:

int health = intent.getIntExtra(BatteryManager.EXTRA_HEALTH, 0);
int plugged = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED, 0);
int voltage = intent.getIntExtra(BatteryManager.EXTRA_VOLTAGE, 0);

以上三个的值分别为 2,2 和 4。

我如何解码这些值并向用户展示一些对健康有意义的东西，如果电池健康状况好、坏或需要更换，我不能告诉计算机如何。

提前致谢

Answer 1

用这个做电池

switch (health) {
    case BatteryManager.BATTERY_HEALTH_DEAD:

        break;
    case BatteryManager.BATTERY_HEALTH_GOOD:

        break;
    case BatteryManager.BATTERY_HEALTH_COLD:

        break;
    case BatteryManager.BATTERY_HEALTH_OVERHEAT:

        break;
    case BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE:

        break;

    default:
        break;
    }

用于插入

switch (plugged ) {
    case BatteryManager.BATTERY_PLUGGED_AC:

        break;
    case BatteryManager.BATTERY_PLUGGED_USB:

        break;
    case BatteryManager.BATTERY_PLUGGED_WIRELESS:

        default:
        break;
    }

用于电压

switch (voltage) {
    case BatteryManager.BATTERY_STATUS_CHARGING:

        break;
    case BatteryManager.BATTERY_STATUS_DISCHARGING:

        break;
    case BatteryManager.BATTERY_STATUS_FULL:
        break;
    case BatteryManager.BATTERY_STATUS_NOT_CHARGING:
        break;
    case BatteryManager.BATTERY_STATUS_UNKNOWN:
        break;
    default:
        break;
    }
