將DataMap轉換爲字符串或字符串數組

我正在通過DataMap將Android手機的天氣數據傳輸到可穿戴Android Wear的過程中。將DataMap轉換爲字符串或字符串數組

我已經設法得到設備上的DataMap，但需要找到一種方法，如何將其轉換爲一個長字符串（然後拆分成數組）或字符串數組。

任何想法？

現行規範對電話：

DataMap dataMap = new DataMap(); 
dataMap.putLong("1-#TIME-STAMP:", System.nanoTime()); 
dataMap.putLong("2-#CONTENT:", 0); 
dataMap.putString("time:", currentWeather[0]); 
dataMap.putString("summary:", currentWeather[1]); 
dataMap.putString("icon:", currentWeather[2]); 
dataMap.putString("nearestStormDistance:", currentWeather[3]); 
dataMap.putString("nearestStormBEaring:", currentWeather[4]); 
dataMap.putString("precipIntensity:", currentWeather[5]); 
dataMap.putString("precipPRobability:", currentWeather[6]); 
dataMap.putString("temperature:", currentWeather[7]); 
dataMap.putString("apparentTemperature:", currentWeather[8]); 
dataMap.putString("dewPoint:", currentWeather[9]); 
dataMap.putString("humidity:", currentWeather[10]); 
dataMap.putString("windSpeed:", currentWeather[11]); 
dataMap.putString("windBearing:", currentWeather[12]); 
dataMap.putString("visibility:", currentWeather[13]); 
dataMap.putString("cloudCover:", currentWeather[14]); 
dataMap.putString("pressure:", currentWeather[15]); 
dataMap.putString("ozone:", currentWeather[16]); 
new SendToDataLayerThread("/data_from_phone", dataMap).start();

現行規範對耐磨：

@Override 
public void onDataChanged(DataEventBuffer dataEvents) 
{ 
    DataMap dataMap; 
    for (DataEvent event : dataEvents) 
    { 
     Log.v("myTag", "DataMap item: " + DataMapItem.fromDataItem(event.getDataItem()).getDataMap()); 
    } 
}

我知道你想要一個字符串數組中的所有值。一旦你對你的設備數據圖的對象，你可以做，在下列方式：

ArrayList<String> listOfDataItems = new ArrayList<String>(); 
for(String key: dataMap.keySet()) 
{ 
    Object value = get(key); 
    if(value instanceof Long) 
    { 
     listOfDataItems.add(String.valueOf(value)); 
    } 
    else if(value instanceof String) 
    { 
     listOfDataItems.add(value); 
    } 
} 
String [] arrayOfDataItems = listOfDataItems.toArray(new String[listOfDataItems.size()]);
