Question

Im trying to solve this problem for about 2 hours. So Im glad for every possible answer.
Ive got a custom ListViewAdapter and it takes his content from an Array. But I have 19 Arrays and I want to change the Content(therefor the Array) based on which date the User clicks(there is a Calendar on the top with 19 Dates).
Here is a picture:

So by default ervy time you open the App the content from the “date_1” Array will be shown(for the 25. in the calender). And when you click on an other date the content from the Array belonging to this date will be shown(e.g. 26. -> date_2, 27. date_3 and so on).
Every Array has to get load from the resources and is saved in a single Array Variable.

So my problem:
I can’t change the Array. Here is my code:

// this is the Array Variable:

   String[] day_chosen;
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.calender);
          [...]
            prepareArrayLits();
            lview3 = (ListView) findViewById(R.id.listView1);

            adapter = new ListViewCustomAdapter(this, itemList);
            lview3.setAdapter(adapter);

            lview3.setOnItemClickListener(this);

        }

        public void onItemClick1(AdapterView<?> arg0, View arg1, int position, long id) {
            // TODO Auto-generated method stub

        }

        /* Method used to prepare the ArrayList,
         */

        public void prepareArrayLits()
        {
            // this is where the Arrays get loaded from the resource:
             day_chosen = getResources().getStringArray(R.array.date_1);

//this Array is not relvant:
            String[] sports = getResources().getStringArray(R.array.sports_array);


            itemList = new ArrayList<Object>();
             for (int counter = 0; counter < day_chosen.length; counter+=4){


                 int Intparser = Integer.parseInt(day_chosen[counter+1]);


                 AddObjectToList(imgid(Intparser),  sports[Intparser],day_chosen[counter],day_chosen[counter+3], backgroundbox(Intparser)) ;
             }


        }

        // Add one item into the Array List
        public void AddObjectToList(int image, String title, String desc, String time, int backbox)
        {

            bean = new ItemBean();
            bean.setBackBox(backbox);
            bean.setTime(time);
            bean.setDescription(desc);
            bean.setImage(image);
            bean.setTitle(title);
            itemList.add(bean);
        }

       [...]
        }

        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            // TODO Auto-generated method stub

        }

// the onClick Events for every date:
        public void onClick(View v) {
            // TODO Auto-generated method stub




              switch(v.getId()){

              case R.id.d_1 :
// I tried to change the Array from here(But it didn't work):
                  day_chosen = getResources().getStringArray(R.array.date_1);


                  break;

              case R.id.d_2 :
                  day_chosen = getResources().getStringArray(R.array.date_2);

                  break;
              [...]

        }



    }

What have I tried:

• I set up a Global Class but it didn’t work

• I tried to set up getters and setters. But also didn’t work

I don’t know how to solve this. Every possible solution is appreciated, Thanks.

Answer 1

I don’t know how you exactly implements your Adapter but did you call yourAdapter.notifyDataSetChanged() when your list content is changed?
