我正在尝试做基本的接收器,并让它在电池状态发生变化时显示祝酒词,但是当一个人发生变化时,所有其他祝酒词也会被执行。
我正在通过 telnet 使用 AVD 操作电池
public class battery1 extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String strCharge = null, strHealth = null, strPlug = null;
int status, health, plugged, temp;
status = intent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
String action = intent.getAction();
if (intent.hasExtra(BatteryManager.EXTRA_STATUS)) {
switch(status) {
case BatteryManager.BATTERY_STATUS_CHARGING:
strCharge = "Charging";
break;
case BatteryManager.BATTERY_STATUS_DISCHARGING:
strCharge = "Discharging";
break;
case BatteryManager.BATTERY_STATUS_FULL:
strCharge = "Full";
break;
case BatteryManager.BATTERY_STATUS_UNKNOWN:
strCharge = "Unknown";
break;
}
Toast.makeText(context,"Charging status: " + strCharge, Toast.LENGTH_SHORT).show();
}
health = intent.getIntExtra(BatteryManager.EXTRA_HEALTH, -1);
if (intent.hasExtra(BatteryManager.EXTRA_HEALTH))
{
switch (health) {
case BatteryManager.BATTERY_HEALTH_DEAD:
strHealth = "Dead";
break;
case BatteryManager.BATTERY_HEALTH_GOOD:
strHealth = "Good";
break;
case BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE:
strHealth = "Over voltage";
break;
case BatteryManager.BATTERY_HEALTH_OVERHEAT:
strHealth = "Overheat";
break;
case BatteryManager.BATTERY_HEALTH_UNKNOWN:
strHealth = "Unknown";
break;
}
Toast.makeText(context,"Battery health is " + strHealth, Toast.LENGTH_SHORT).show();
}
}
}
