直接上代码:

[java]
/* ========================== Battery Start =============================*/

int tBatteryLevel = 0, tBatteryCurLevel = 0;
int tBatteryChargeFlag = -1;

private void Battery(){
int tTempFlag = 0;

ImageButton tTempButton = (ImageButton)findViewById(R.id.top_battery);
tTempButton.setVisibility(View.INVISIBLE);

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
int tTempScale = intent.getIntExtra("scale", 100);
//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
int tTempStatus = intent.getIntExtra("status", 0);

tTempLevel = (tTempLevel * 100) / tTempScale;
if (tTempLevel > 95)
tBatteryLevel = 5;
else if(tTempLevel > 80)
tBatteryLevel = 4;
else if(tTempLevel > 60)
tBatteryLevel = 3;
else if(tTempLevel > 40)
tBatteryLevel = 2;
else if(tTempLevel > 20)
tBatteryLevel = 1;
else
tBatteryLevel = 0;

if (tTempStatus == BatteryManager.BATTERY_STATUS_CHARGING)
tBatteryChargeFlag = 1;
else
tBatteryChargeFlag = 0;
}
}

};

registerReceiver(mIntentReceiver, mIntentFilter);
}
/* ========================== Battery End =============================*/

/* ========================== Battery Start =============================*/

int tBatteryLevel = 0, tBatteryCurLevel = 0;
int tBatteryChargeFlag = -1;

private void Battery(){
int tTempFlag = 0;

ImageButton tTempButton = (ImageButton)findViewById(R.id.top_battery);
tTempButton.setVisibility(View.INVISIBLE);

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
int tTempScale = intent.getIntExtra("scale", 100);
//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
int tTempStatus = intent.getIntExtra("status", 0);

tTempLevel = (tTempLevel * 100) / tTempScale;
if (tTempLevel > 95)
tBatteryLevel = 5;
else if(tTempLevel > 80)
tBatteryLevel = 4;
else if(tTempLevel > 60)
tBatteryLevel = 3;
else if(tTempLevel > 40)
tBatteryLevel = 2;
else if(tTempLevel > 20)
tBatteryLevel = 1;
else
tBatteryLevel = 0;

if (tTempStatus == BatteryManager.BATTERY_STATUS_CHARGING)
tBatteryChargeFlag = 1;
else
tBatteryChargeFlag = 0;
}
}

};

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));
}
}
};

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));
}
}
};
