Parsing sunrise and sunset values from web service

Parsing sunrise and sunset values from web service - java

Okay, so it appears I'm stuck and could do with some help.
After successfully calling this webservice with my current longitude and latitude I am getting the entire xml file back in response.
However the only bit of the xml file I want is the sunrise and sunset times, how do I go about parsing these and only these into TextViews?
I've looked at and attempted countless tutorials on XmlPullParser, DOMParser and SAXParser and I'm now struggling.
Code as requested:

Thanks in advance for your help!

You can try replacing your onPostExecute with the one below and add this import...
import java.io.StringReader;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.InputSource;
protected void onPostExecute(String results) {
if (results != null) {
try {
DocumentBuilderFactory dbFactory = DocumentBuilderFactory
.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
InputSource s = new InputSource(new StringReader(result));
Document doc = dBuilder.parse(s);
doc.getDocumentElement().normalize();
//EditText et = (EditText) findViewById(R.id.my_edit);
TextView tv = (TextView) findViewById(R.id.Date);
tv.setText("sunrise at "+doc.getElementsByTagName("sunrise").item(0).getTextContent() + " sunset at "+doc.getElementsByTagName("sunset").item(0).getTextContent());
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
Button b = (Button) findViewById(R.id.my_button);
b.setClickable(true);
}
EDIT: I'm not sure which TextView you want to set but I guess this one (R.id.Date).
You can change the id if it's not the right one.
//EditText et = (EditText) findViewById(R.id.my_edit);
TextView tv = (TextView) findViewById(R.id.Date);
tv.setText...

I just wanna run a program to analyze source code. I know there is dimens.xml file which is missing but i have no clue what to put there.
I'm new in Android dev so i found example code just to learn how to create apps like that. But it's hard when i cannot run it :D
Thanks for your help.

you may just replace this
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
with smth like
android:paddingBottom="8dp"
android:paddingLeft="8dp"
android:paddingRight="8dp"
android:paddingTop="8dp"
(or if all 4 paddings are equal, you may set just android:padding="8dp")

In res -> Values put this code in dimens.xml
<dimen name="activity_vertical_margin">3dp</dimen>
Adjust dp according to your UI.

android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
replace above code with below lines in RelativeLayout :
android:paddingBottom="16dp"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:paddingTop="16dp"

Thank you to answer

Your question wasnt so clear to me, but i tried to run the code. I had few errors but not where you pointed. i got the error at Toast.makeText('String',Toast.LENGTH_LONG).show(), it should be Toast.makeText(MainActivity.this, "String", Toast.LENGTH_LONG).show(); (you have to pass the context, and put a semicolon after the statement). Now the program is working. i can see an activity with a button, clicking which showed the toast.

Android ListView TextView

I've been struggling to get a listview to display correctly.
To clarify, I need a scrollview above the listview which is why I haven't extended a listfragment.
I need title and description to be separate elements. I can see how I have put them into a class so I think I'm half way there. If someone could help me out that would be great.

Your resource xml is incorrect.
1.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
android:orientation is used with LinearLayout, not RelativeLayout
2.
<ListView
android:id="#id/mListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_below="#+id/relativeLayout">
</ListView>
Incorrect use of android:layout_below - value should be an existing id: "#id/relativeLayout" (without + after #).
android:id="#id/mListView" incorrectly assigned id. If it is a new ID, then should be android:id="#+id/mListView"
Probably you'd like to use LinearLayouts instead of relative
fill_parent is obsolete until you develop for some API 7. Should be match_parent instead

Using the date from DatePicker in the url for sunrise/sunset webservice [duplicate]

This question already has an answer here:
Using the date from DatePicker in URL for webservice
(1 answer)
Closed 9 years ago.
Okayyyy, so I'm stuck and could do with some help :)
In my code at the moment today's date is being read into the webservice url using the following snippet of code:
Calendar c = Calendar.getInstance();
System.out.println("Current time => " + c.getTime());
SimpleDateFormat df = new SimpleDateFormat("dd/MM");
String formattedDate = df.format(c.getTime());
I want today's date to be displayed but I also want the user to be able to select a different date from the DatePicker and find the sunrise/sunset values for that particular date.
I'm guessing this is simple and I'm just being a bit dim so any help would be appreciated, here is my code:

Like I said any help would be massively appreciated =)
Thanks for looking.

I am not sure about your requirement but I guess you can try changing from
String formattedDate = df.format(c.getTime());
to
String formattedDate = df.format(now.getTime());
This is pretty dirty but I think it should work just fine.
Your doInBackground should look like this:
#Override
protected String doInBackground(Void... params) {
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
// Finds todays date and adds that into the URL
//Calendar c = Calendar.getInstance();
//System.out.println("Current time => " + c.getTime());
SimpleDateFormat df = new SimpleDateFormat("dd/MM");
String formattedDate = df.format(now.getTime());
String finalURL = "http://www.earthtools.org/sun/"
+ LatCoord.getText().toString().trim() + "/"
+ LongCoord.getText().toString().trim() + "/"
+ formattedDate + "/99/0";
HttpGet httpGet = new HttpGet(finalURL);
String text = null;
try {
HttpResponse response = httpClient.execute(httpGet,
localContext);
HttpEntity entity = response.getEntity();
text = getASCIIContentFromEntity(entity);
} catch (Exception e) {
return e.getLocalizedMessage();
}
return text;
}
Hope this helps.

Calling different methods depending on which Spinner item is selected - Android

I've been looking at this tutorial for how to use Spinners but I'm now stuck.
Currently when an item is selected from the spinner a toast is displayed with the choice, what I want to do instead is run a method to set the latitude and longitude to the selected country.
The button "Set Location to Japan" works perfectly by calling the method "SetLocationJapan". I just want take this process and put it into the spinner so whenever a choice is made the latitude and longitude is updated.
For example:
if Japan is selected in the spinner I want to call protected void setLocationJapan()
if France is selected I want to call protected void setLocationFrance()
if India is selected I want to call protected void setLocationIndia()

Any help would be hugely appreciated, Thanks!
I'm pretty sure I need to move setLocationJapan() etc. inside the CustomOnItemSelectedListener class but don't know how to proceed from there.
I'd prefer pseudo code answers so I can work this out for myself if possible :)

This is a bit dirty, but you can pass your activity to CustomOnSelectedListener and then call those methods using the activity. Example:
public class CustomOnSelectedListener extends implements OnItemSelectedListener {
Activity mActivity;
CustomOnSelectedListener(Activity mActivity) {
this.mActivity = mActivity;
}
public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) {
Toast.makeText(parent.getContext(),
"You have changed to : " + parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_SHORT).show();
if (mActivity instanceof SunriseSunset) {
SunriseSunset sunrise = (SunriseSunset) mActivity;
switch (pos) {
case 1: // Assuming Japan is first on your list
sunrise.setLocationJapan();
break;
... // fill in the rest here
}
}
}
... // rest of CustomOnSelectedListener here
}
However, this means all your setLocationJapan, setLocationIndia, etc. must change from protected to public so CustomOnSelectedListener can call them. Also, you must now instantiate CustomOnSelectedListener like this:
spinner1.setOnItemSelectedListener(new CustomOnItemSelectedListener(this));
