When I display onformLoad it working but, now I need to display it using a buttton, here my two classess :

    B_KZN.setOnClickListener(new View .OnClickListener() {

        @Override
            public void onClick(View Kv) {
    // TODO Auto-generated method stub

   JSONObject json = JSONfunctions.getJSONfromURL("http://10.0.2.2/php/p.php");

   try{

            JSONArray  earthquakes = json.getJSONArray("SKZN");

           for(int i=0;i<earthquakes.length();i++){                     

            JSONObject e = earthquakes.getJSONObject(i);    
            String BookName = e.getString("P_City");
        PNames.add(BookName);
    String BookImg = e.getString("Pname");
        PImages.add(BookImg);
    }       
        }catch(JSONException e){
         Log.e("log_tag", "Error parsing data "+e.toString());
    }                   
        setListAdapter(new MobileArrayAdapter(this, PNames,PImages));

public class MobileArrayAdapter extends ArrayAdapter<String> {
    private final Context context;
    private final String[] myBookNamelist = null;
    private ArrayList<String> MyP = new ArrayList<String>();
    private ArrayList<String> myPurl = new ArrayList<String>();

    public MobileArrayAdapter(Context context,ArrayList<String> Bname,ArrayList<String> BUrl) {
        super(context, R.layout.list_mobile, Bname);
        this.context = context;
        this.MyP = Bname;
        this.myPurl = BUrl;

Your declaring this as your Context. But you are in an Annoymous class of type View.OnClickListener

try this instead:

 setListAdapter(new MobileArrayAdapter(YourActivityName.this, PNames,PImages));

The first parameter of the constructor is of type Context, however when passing this to the constructor you are inside a subclass of View.OnClickListener. As you are in an inner-class of your (most likely) activity, you just need to indicate that you want to pass the parent activity instance.

Where you're creating the adapter, use MyActivity.this:

setListAdapter(new MobileArrayAdapter(MyActivity.this, PNames,PImages));

way to take my answer and re-word it :p

@Blundell I beg your pardon? I wrote this at the same time as you wrote yours, independently. Unfortunately, SO doesn't show "seconds ago", only minutes. You'd probably see that our two answers differ by about 5 seconds. I don't like when others copy my answers and I don't do it myself.

It does show edit's too your answer, and I watched your original answer then your change. Don't worry yourself

@Blundell: yes, I changed it. I often answer with the main point and then update with more information. Is that a crime? :) But I'll give you a +1.

Use this code in your activity where you set adapter to your ListView, it will work

setListAdapter(new MobileArrayAdapter(yourActivityname.this, PNames,PImages));
