Java 如何从android中的电池管理器类获取电池温度？

这是我的BattreyInfo.java文件。我正试图提取电池温度并将其显示在屏幕上。Eclipse表示，

broadcastReceiver

无法解析为类型。我不明白。我已经正确地导入了这个包。它也无法识别接收时的

onreceive

功能。我是否必须为

广播接收器

制作另一个类或其他内容

package com.example.batterywidget;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.BatteryManager;
import android.widget.TextView;
import android.content.BroadcastReceiver;
import android.content.Context; 
import android.content.IntentFilter;
import android.graphics.Color; 
import android.view.View;


public class BatteryInfo extends Activity {

private TextView BatTemp;
BroadcastReceiver mBatInfoReciever = new BroadcastReceiver(){

    @Override
    public void onRecieve(Context arg0, Intent intent){
        int temp = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE, 0);
        BatTemp.setText(String.valueOf(temp) + "%");

    }
};

    //called when the activity is first created
    @Override
     public void onCreate(Bundle binfo){
     super.onCreate(binfo);
     setContentView(R.layout.batteryinfo);
     BatTemp = (TextView) this.findViewById(R.id.battery_temp);


    }
    @Override
    protected void onResume() {
            super.onResume();
            IntentFilter filter = new IntentFilter();

            filter.addAction(Intent.ACTION_BATTERY_CHANGED);
            registerReceiver(mBatInfoReceiver, filter);
    }
    @Override
    protected void onPause() {
            super.onPause();
            unregisterReceiver(mBatInfoReceiver);
    }

}

这是我用来获取温度的代码

batteryReceiver = new BroadcastReceiver() {
            int level = -1;
            int scale = -1;
            int temperature = -1;
            @Override
            public void onReceive(Context context, Intent intent) {
                level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
                scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
                temperature = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE, -1);

                int health = intent.getIntExtra("health",BatteryManager.BATTERY_HEALTH_UNKNOWN);
                String strHealth;
                if (health == BatteryManager.BATTERY_HEALTH_GOOD){
                    strHealth = "Good";
                } else if (health == BatteryManager.BATTERY_HEALTH_OVERHEAT){
                    strHealth = "Over Heat";
                } else if (health == BatteryManager.BATTERY_HEALTH_DEAD){
                    strHealth = "Dead";
                } else if (health == BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE){
                    strHealth = "Over Voltage";
                } else if (health == BatteryManager.BATTERY_HEALTH_UNSPECIFIED_FAILURE){
                    strHealth = "Unspecified Failure";
                } else{
                    strHealth = "Unknown";
                }


                batteryStatusTextView.setText(" Temperature: "+temperature/10+"C" + " " + strHealth);

            }
        };
        IntentFilter filter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
        registerReceiver(batteryReceiver, filter);

BroadcastReceiver是一个抽象类。这意味着您无法创建它的实例。您必须创建自己的类并扩展BroadcastReceiver

我认为您可以将所有现有代码复制到新类中

你好像有3个广播员。 第一个应该是这样的：

public class BatInfoReceiver extends BroadcastReceiver{
 @Override
    public void onRecieve(Context arg0, Intent intent){
        int temp = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE, 0);
        BatTemp.setText(String.valueOf(temp) + "%");

    }
}

现在可以创建此类的实例：

BatInforeceiver mBatInfoReceiver = new BatInfoReceiver();

然后对其他两个广播接收机也执行相同的操作。

是。但是你是怎么写BroadCatReceiver的。我的eclipse说它不能解析为类型。我知道这是一个抽象类，但我应该如何更正它。我是否应该使用BroadcastReceiver而不是Activity扩展BatteryInfo？batteryReceiver的声明如下：public BroadcastReceiver batteryReceiver；就这样。我的类只是一个activity，它没有实现任何与BroadcastReceiver相关的东西。我只导入了import android.content.BroadcastReceiver；上面的代码是在onCreate中实现的。就这些。我应该用广播接收器而不是活动来扩展BatteryInfo吗？非常感谢您的帮助。我希望我有足够的声誉来投票支持这个！上帝保佑你的项目：）问题是我的eclipse说BroadcastReceiver不能解析为一个类型？怎么样？我已经正确地导入了这个包。我是否需要在单独的java文件中创建BroadcastReceiver类？

public class BatInfoReceiver extends BroadcastReceiver{
 @Override
    public void onRecieve(Context arg0, Intent intent){
        int temp = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE, 0);
        BatTemp.setText(String.valueOf(temp) + "%");

    }
}

BatInforeceiver mBatInfoReceiver = new BatInfoReceiver();
