i would like to display image from drawable.
However, I think that my if else having problem
because the statement for displaying image is correct..
and ya,
I would like to display the image based on the weather text.
Such as
<yweather:condition text="Light Rain" code="11" temp="26" date="Thu, 18 Jul 2013 12:00 pm SGT" />
so when I code it, it will display "logo.png" for the text "Light Rain"
Here are my code.
MainActivity.java
public class MainActivity extends Activity {
TextView weather;
ImageView image;
class MyWeather{
String conditiontext;
String conditiondate;
String numberOfForecast;
String forecast;
public String toString(){
return "\n- "
+ "Weather:" + image + "\n"
+ "Condition: " + conditiontext + "\n"
+ conditiondate +"\n"
+ "\n"
+ "number of forecast: " + numberOfForecast + "\n"
+ forecast;
}
}

final MyWeather weatherResult = parseWeather(weatherDoc);

@Override
public void run() {
weather.setText(weatherResult.toString());
}});
}});
myThread.start();
}
private MyWeather parseWeather(Document srcDoc){
MyWeather myWeather = new MyWeather();
//<yweather:condition.../>
Node conditionNode = srcDoc.getElementsByTagName("yweather:condition").item(0);
if(conditionNode.getTextContent().equals("11")){
image.setImageResource(R.drawable.logo);
}
else {
image.setImageResource(R.drawable.old);
}
myWeather.conditiontext = conditionNode.getAttributes()
.getNamedItem("text")
.getNodeValue()
.toString();
myWeather.conditiondate = conditionNode.getAttributes()
.getNamedItem("date")
.getNodeValue()
.toString();
//Added to get elements of <yweather:forecast.../>
NodeList forecastList = srcDoc.getElementsByTagName("yweather:forecast");
myWeather.forecast = "";
if(forecastList.getLength() > 0){
myWeather.numberOfForecast = String.valueOf(forecastList.getLength());
for(int i = 0; i < forecastList.getLength(); i++){
Node forecastNode = forecastList.item(i);
myWeather.forecast +=
forecastNode
.getAttributes()
