Question

如何在Android中获取电池的温度？

Answer 1

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

public static final String EXTRA_TEMPERATURE
ACTION_BATTERY_CHANGED：包含当前电池温度的整数。

Answer 2

试试这个：

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);
    }

};

然后在您的变量声明中定义：

private mBatInfoReceiver myBatInfoReceiver;

并在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));

     }

稍后在OnClickListener（）

中调用

float temp = myBatInfoReceiver.get_temp(); 

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

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));
      }

Answer 5

尝试阅读static int BatteryManager.EXTRA_TEMPERATURE

Answer 6

您可以通过此功能获得CPU温度：使用sys/class/thermal/temp命令从Android设备获取CPU温度。

public float getCpuTemp() {
    Process process;
    try {
        process = Runtime.getRuntime().exec("cat sys/class/thermal/thermal_zone0/temp");
        process.waitFor();
        BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line = reader.readLine();
        float temp = Float.parseFloat(line) / 1000.0f;
        return temp;
    } catch (Exception e) {
        e.printStackTrace();
        return 0.0f;
    }
}
