Question

我需要知道（通过我的应用）Android设备是否正在充电。有任何想法吗？感谢

Answer 1

我发现的一件事是，如果您的手机具有100％的电池电量，您将无法收到充电通知。有些人意味着充电，而其他人则意味着有外部能力，无论是100％。我把它们混为一体，如果有任何条件是真的，那我就回归真。

public static boolean isPhonePluggedIn(Context context){
    boolean charging = false;

    final Intent batteryIntent = context.registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
    int status = batteryIntent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
    boolean batteryCharge = status==BatteryManager.BATTERY_STATUS_CHARGING;

    int chargePlug = batteryIntent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);
    boolean usbCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_USB;
    boolean acCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_AC;

    if (batteryCharge) charging=true;
    if (usbCharge) charging=true;
    if (acCharge) charging=true; 

    return charging;
}

Answer 2

以下是有效的代码：

Intent bat = loader.registerReceiver(null, new
        IntentFilter(Intent.ACTION_BATTERY_CHANGED));
int level = bat.getIntExtra("level", 0);
int scale = bat.getIntExtra("scale", 100);
return level * 100 / scale;

Answer 3

    public static boolean isBatteryCharging(Context context){
    // Check battery sticky broadcast
    final Intent batteryIntent = context.registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
    return (batteryIntent.getIntExtra(BatteryManager.EXTRA_STATUS, -1) == BatteryManager.BATTERY_STATUS_CHARGING);
}
