在电池广播接收器中,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);
以上三个的值为2,2和4。
我如何解码这些值并向用户展示对健康有意义的事情,如果电池健康状况良好,不良或需要更换,我不能知道计算机是怎样的。
提前致谢

将此用作电池
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;
}

在onCreate方法下使用
@Override
public void onCreate() {
BroadcastReceiver batteryReceiver = new BroadcastReceiver() {
int scale = -1;
int level = -1;
int voltage = -1;
int temp = -1;
@Override
public void onReceive(Context context, Intent intent) {
level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
temp = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE, -1);
voltage = intent.getIntExtra(BatteryManager.EXTRA_VOLTAGE, -1);
Log.e("BatteryManager", "level is "+level+"/"+scale+", temp is "+temp+", voltage is "+voltage);
}
};
IntentFilter filter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
registerReceiver(batteryReceiver, filter);
}
如果等级= 20/100表示电池剩余20% 温度是320然后温度是32度celcuis。 如果电压为4000,那么电压为4.000伏
