Android編程實現檢測當前電源狀態的方法

本文實例講述了Android編程實現檢測當前電源狀態的方法。分享給大家供大家參考，具體如下：

檢測到現在在電源狀態:

IntentFilter mIntentFilter = new IntentFilter();
mIntentFilter.addAction(Intent.ACTION_BATTERY_CHANGED);
registerReceiver(mIntentReceiver, mIntentFilter);
//聲明消息處理過程
 private BroadcastReceiver mIntentReceiver = new BroadcastReceiver() {
  @Override
  public void onReceive(Context context, Intent intent) {
   String action = intent.getAction();
   //要看看是不是我們要處理的消息
   if (action.equals(Intent.ACTION_BATTERY_CHANGED)) {
    //電池電量，數字
    Log.d("Battery", "" + intent.getIntExtra("level", 0));
    //電池最大容量
    Log.d("Battery", "" + intent.getIntExtra("scale", 0));
    //電池伏數
    Log.d("Battery", "" + intent.getIntExtra("voltage", 0));
    //電池溫度
    Log.d("Battery", "" + intent.getIntExtra("temperature", 0));
    //電池狀態，返回是一個數字
    // BatteryManager.BATTERY_STATUS_CHARGING 表示是充電狀態
    // BatteryManager.BATTERY_STATUS_DISCHARGING 放電中
    // BatteryManager.BATTERY_STATUS_NOT_CHARGING 未充電
    // BatteryManager.BATTERY_STATUS_FULL 電池滿
    Log.d("Battery", "" + intent.getIntExtra("status", BatteryManager.BATTERY_STATUS_UNKNOWN));
    //充電類型 BatteryManager.BATTERY_PLUGGED_AC 表示是充電器，不是這個值，表示是 USB
    Log.d("Battery", "" + intent.getIntExtra("plugged", 0));
    //電池健康情況，返回也是一個數字
    //BatteryManager.BATTERY_HEALTH_GOOD 良好
    //BatteryManager.BATTERY_HEALTH_OVERHEAT 過熱
    //BatteryManager.BATTERY_HEALTH_DEAD 沒電
    //BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE 過電壓
    //BatteryManager.BATTERY_HEALTH_UNSPECIFIED_FAILURE 未知錯誤
    Log.d("Battery", "" + intent.getIntExtra("health", BatteryManager.BATTERY_HEALTH_UNKNOWN));
   }
  }
};

希望本文所述對大家Android程序設計有所幫助。
