如何知道手機是否在充電

Question

我需要知道（通過我的應用程序）Android設備是否正在充電。有任何想法嗎？感謝

Answer 1

下面是工作代碼：

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 2

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); 
} 

Answer 3

有一件事我發現是，如果你的手機有100％的電量，你不會得到充電通知。有些人指的是充電和其他人的意思，當它有外部的力量，無論是否100％。我把這些歸入一個，如果任何情況是真的，那麼我會回報真實的。

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; 
}
