Question

I need to display image and text in my listview when i click a button search but it giving me an error in my setListAdapter(new MobileArrayAdapter(this, PNames,PImages));.. I have two classes.
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));

And my second Class, :

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;
    }

here my error : The constructor MobileArrayAdapter(new View.OnClickListener(){}, ArrayList<String>, ArrayList<String>) is undefined…it showing me red line.

Answer 1

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));
