直接上代码:

[java]

int tBatteryChargeFlag = -1;

private void Battery(){

int tTempFlag = 0;

ImageButton tTempButton = (ImageButton)findViewById(R.id.top_battery);

IntentFilter mIntentFilter = new IntentFilter();

mIntentFilter.addAction(Intent.ACTION_BATTERY_CHANGED);

// 声明消息处理过程

BroadcastReceiver mIntentReceiver = new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

// TODO Auto-generated method stub

String action = intent.getAction();

if(action.equals(Intent.ACTION_BATTERY_CHANGED)){

//电池电量，数字

int tTempLevel = intent.getIntExtra("level", 0);

//电池最大容量

//电池状态，返回是一个数字

// BatteryManager.BATTERY_STATUS_CHARGING 表示是充电状态

}

}

};

registerReceiver(mIntentReceiver, mIntentFilter);

}

/* ========================== Battery End =============================*/

另外还有一份别人的参考代码:

[java]

检测到现在在电源状态:

IntentFilter mIntentFilter = new IntentFilter();

mIntentFilter.addAction(Intent.ACTION_BATTERY_CHANGED);

registerReceiver(mIntentReceiver, mIntentFilter);

//声明消息处理过程

private BroadcastReceiver mIntentReceiver = new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

//要看看是不是我们要处理的消息

if (action.equals(Intent.ACTION_BATTERY_CHANGED)) {

//电池电量，数字

Log.d("Battery", "" + intent.getIntExtra("level", 0));

//电池最大容量

Log.d("Battery", "" + intent.getIntExtra("scale", 0));

//电池伏数

Log.d("Battery", "" + intent.getIntExtra("voltage", 0));

//电池温度

Log.d("Battery", "" + intent.getIntExtra("temperature", 0));

//电池状态，返回是一个数字

// BatteryManager.BATTERY_STATUS_CHARGING 表示是充电状态

// BatteryManager.BATTERY_STATUS_DISCHARGING 放电中

// BatteryManager.BATTERY_STATUS_NOT_CHARGING 未充电

// BatteryManager.BATTERY_STATUS_FULL 电池满

Log.d("Battery", "" + intent.getIntExtra("status", BatteryManager.BATTERY_STATUS_UNKNOWN));

//充电类型 BatteryManager.BATTERY_PLUGGED_AC 表示是充电器，不是这个值，表示是 USB

Log.d("Battery", "" + intent.getIntExtra("plugged", 0));

//电池健康情况，返回也是一个数字

//BatteryManager.BATTERY_HEALTH_GOOD 良好

//BatteryManager.BATTERY_HEALTH_OVERHEAT 过热

//BatteryManager.BATTERY_HEALTH_DEAD 没电

//BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE 过电压

//BatteryManager.BATTERY_HEALTH_UNSPECIFIED_FAILURE 未知错误

Log.d("Battery", "" + intent.getIntExtra("health", BatteryManager.BATTERY_HEALTH_UNKNOWN));

}

}

};
