【Android开发学习32】BroadcastReceiver之电源管理

直接上代码:

/* ========================== 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() {@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubString 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;elsetBatteryLevel = 0;if (tTempStatus == BatteryManager.BATTERY_STATUS_CHARGING)tBatteryChargeFlag = 1;elsetBatteryChargeFlag = 0;}}};registerReceiver(mIntentReceiver, mIntentFilter); }/* ========================== Battery End   =============================*/

另外还有一份别人的参考代码:

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));             }         }     };
