inserting call button in list view - java

I have a project which shows list of blood donors using place search, i want to insert a call button in that list view for each user, i have no idea how to add it, Can you please help me with this? Screenshot 1: Screenshot 2: Each detail of the blood donor like name , blood group and phone are stored in each field in the server. "bld_phn" is the id of text view that shows phone number."phone" is the array string
code:

For call button in listview you can add call button icon in listview's row file like below:-
<Button
android:id="#+id/buttonCall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Call" />
Then in activity, you can write below code in on click of call button to call functionality in android:-
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("phone number"));
startActivity(callIntent);
phone number in above code is a string var in which you can add number which you want to call.
I hope it will help you.

How to add multiple values inside 1 list view and style it approriatle

I want to be able to add multiple values on a list but properly style the list view.
For example right now the list view will look like this:
namepostcodedate
which is because of the following code
ListArray.add(jobs.get(finalJ).customer.getName() + job.getPostcode() + job.getDate());
The way that I am currently adding the values in the ListArray doesn't seem ideal but I am not sure if there is another way to do this and display the list formated?
This is my list_item file

listview not getting displayed

I am trying to filter data from database and display filtered data into listview using cursor. Unfortunately, the cursor is returned from the query isn't empty but the items not getting displayed in the activity.And moreover, there's no error being displayed in the logcat.
My search_results.java:

Now, the cursor isn't empty but the listview is not displayed by the listview adapter.
Can someone point out the error in the code??

Please use this.
#Override
public int getCount() {
//here too;
return depart.lenght;
}
#Override
public Object getItem(int i) {
//there is error: repalce return null; with
return depart[i];
}
#Override
public long getItemId(int i) {
//change this too
return depart[i].getId();
}

I can see 2 reasons that this may happen:
You arrays are not filled with data/or filled with empty data and that the reason they are not presented. (less likely because you would receive a null pointer exception when you try to access a null location in the array)
Your row layout doesn't show data parameters. (I will be
on this reason, please show you row layout XML(listview_items.xml) so that we could check
it)
Check: Make a check and print to the log all the data from 6 the arrays for every row before you set the data in the getView method.

getCount(), getItem() and getItemId() are not set properly.
getCount() should return the number of items in the arraylist;
getItem() should return the item at the given position from the arraylist;
getItemId() should return the internal id of the item if it has one, or the position of the item in the array or an hash number of the item.

how to show default list in spinner in android

I think should try something like that to show the default values if no internet, else get the values of the sql
if(cd.isConnectingToInternet()){
prodropdown();
}else{
//Setting adapter to show the items in the spinner
List<String> spinnerArray = new ArrayList<String>();
spinnerArray.add("default value 1");
spinnerArray.add("default value 2");
spinnerArray.add("default value 3");
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_item, spinnerArray);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter);
}

Listview and sharedprefs

So i'm currently working on a app that i can use while training. What i'm trying to achieve here is to log what i'm doing everyday in so i can later on see how my progress is going..
This is what i have done so far.

Result
What i'm trying to do here is to get input text form the Mainactivity layout to the listview and to be sorted in columns. This part works perfectly. What i cannot figre out is how to add more "items". When i do this the data thats been saved (Trening) in SharedPrefs will be overwritten. So do how could i add more data ? is there perhaps another way i should do this? if so please tell!

As Youxian stated, your data is being overwritten when put in the same key. Because you are going to repeat this overriding process every day, you will not be able to get an accurate log of daily workout data. Instead, use database to store your data. Here is how shared prefs works:
(windowsphone.interoperabilitybridges.com)
As you can see in this diagram, they IsolatedStorageSettings is based off of the key/value pairs, which you are overriding right now. That is the way that the compiler even knows what data to get, by the key:
(kb4dev.com)
So again, I suggest you use either different keys to prevent overriding, or you use data base.

SharedPreference is like key and value, so you always put data in the same key(O1,R1,S1,KG1). The data you stored would be overwritten. if you want to use shared preference anyway, just put values in different keys (like add a counter after key name). and use getAll() method to show them in your list.
you can see these for more information about shared preference:
http://developer.android.com/intl/es/reference/android/content/SharedPreferences.html
http://developer.android.com/intl/es/reference/android/content/SharedPreferences.Editor.html
Using android SQLite database to do this might be a choice, learn more:
