Obtener temperatura de la batería en Android

Question

¿Cómo consigo la temperatura de la batería en Android?

Answer 1

Prueba esto:

private class mBatInfoReceiver extends BroadcastReceiver{ 

    int temp = 0;

    float get_temp(){
        return (float)(temp / 10);
    }

    @Override 
    public void onReceive(Context arg0, Intent intent) {
        temp = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE,0);
    }

};

A continuación, definir en sus declaraciones de variables:

private mBatInfoReceiver myBatInfoReceiver;

y en onCreate:

    @Override 
    public void onCreate(Bundle b) { 
        super.onCreate(b);  
        setContentView(R.layout.activity_main);

        // ...
        // Add this

        myBatInfoReceiver = new mBatInfoReceiver();                                     

        this.registerReceiver(this.myBatInfoReceiver,
                              new IntentFilter(Intent.ACTION_BATTERY_CHANGED));

     } 

más tarde llamar por ejemplo en un OnClickListener ()

float temp = myBatInfoReceiver.get_temp(); 

String message = "Current " + BatteryManager.EXTRA_TEMPERATURE + " = " +
                  temp +  Character.toString ((char) 176) + " C";

Answer 2

http://developer.android.com/reference/android/os/ BatteryManager.html

public static final String EXTRA_TEMPERATURE
Adicional para ACTION_BATTERY_CHANGED: entero que contiene la temperatura actual de la batería.

Answer 3

    public static String batteryTemperature(Context context)
    {
        Intent intent = context.registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));    
        float  temp   = ((float) intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE,0)) / 10;
        return String.valueOf(temp) + "*C";
    }

Answer 4

TextView BatTemp;

private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent intent) 
        {

          // TODO Auto-generated method stub

          int temp = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE,0);

      };

@Override
      public void onCreate(Bundle b) 
      {
        super.onCreate(b);
        setContentView(R.layout.activity_main);


        BatTemp = (TextView) this.findViewById(R.id.textView8);

        this.registerReceiver(this.mBatInfoReceiver,new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
      }
