Multi-Dimensional Checkbox array in android

Question

Am trying to create dynamic checkboxes based on contents of two tables. I am able to create the checkboxes but the problem comes on the OnCheckedChangeListener where i cant pick the index of the clicked checkbox. Below is my code. Any assistance is highly appreciated

I call getViews() on the onCreate() Method

public void getViews(){

    // TableLayout ref from xml where we want to Display list
    final TableLayout proF = (TableLayout) findViewById(R.id.TableLayout_views);

    // Get the database and run the query       
    final SQLiteDatabase datb = mDatabase.getWritableDatabase();

    Cursor curs = datb.rawQuery("SELECT * FROM " + tarea.AREA_TABLE_NAME
            + " WHERE " + tarea.AREA_ID + " LIKE '" +"1"+ "' ", null);      
    curs.moveToFirst();

    if (curs.getCount() > 0) {

        for (int i = 0; i < curs.getCount(); i++) {
            area_id = curs.getInt(curs.getColumnIndex(tarea.AREA_ID));
            curs.moveToNext();
        }
    }

    System.out.println("Area Id is : " + area_id);

    Cursor cur = datb.rawQuery("SELECT * FROM " + tclass.CLASS_TABLE_NAME
            + " WHERE " + tclass.CLASS_AREA_ID + " LIKE '" +area_id+ "' ", null);       
    cur.moveToFirst();

    clss = new String[cur.getCount()];

    if (cur.getCount() > 0) {
        int i ;
        for (i = 0; i < cur.getCount(); i++) {
            clss[i] = cur.getString(cur.getColumnIndex(tclass.CLASS_ITEM));
            System.out.println("Class item : " + clss[i]);

            class_id = cur.getInt(cur.getColumnIndex(tclass.CLASS_ID));

            System.out.println("Class Id is : " + class_id);

            Cursor c = datb.rawQuery("SELECT * FROM " + tmonitoring.MONITORING_TABLE_NAME
                    + " WHERE " + tmonitoring.MONITORING_CLASS_ID + " LIKE '" +class_id+ "' ", null);

            c.moveToFirst();

            avail = new CheckBox[cur.getCount()][c.getCount()];
            edtbox = new EditText[cur.getCount()][c.getCount()];
            System.out.println("cur.getCount()>>" + cur.getCount());
            System.out.println("c.getCount()>>" + c.getCount());

            cur.moveToNext();
        }
    }

    curs.close();
    cur.close();
    datb.close();


}

My click listener is as below

private OnCheckedChangeListener checkListener = new OnCheckedChangeListener() {

    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        // TODO Auto-generated method stub
        // Test avail Checkbox
        StringBuffer r = new StringBuffer();
        int clss;
        db1 = mDatabase.getReadableDatabase();

        System.out.println("area_id on click listener : " + area_id);

        Cursor cur = db1.rawQuery("SELECT * FROM " + tclass.CLASS_TABLE_NAME
                + " WHERE " + tclass.CLASS_AREA_ID + " LIKE '" +area_id+ "' ", null);   

        cur.moveToFirst();
        for(int i = 0; i < cur.getCount(); i++){

            clss = cur.getInt(cur.getColumnIndex(tclass.CLASS_ID));

            System.out.println("Classid on click listener : " + clss);

            results = db1.rawQuery("SELECT "+tmonitoring.MONITORING_ITEM+" FROM " + tmonitoring.MONITORING_TABLE_NAME
                    + " WHERE " + tmonitoring.MONITORING_CLASS_ID + " LIKE '" +clss+ "' ", null);



            for (int u = 0; u < results.getCount(); u++) {
                if (avail[u] != null) {
                    r.append("\nResults->" + u + " : ").append(
                            avail[i][u].isChecked());

                }
            }
            cur.moveToNext();
        }
        cur.close();
        results.close();
        db1.close();
    }
};

The part where i check if isChecked() throws ArrayIndexOutOfBoundsException. Please help

setting the tag will help you to recognize the created checkbox on later stage.

avail = new CheckBox[cur.getCount()][c.getCount()]; avail.setTag(i);//add this line

And inside

public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) Integer i=(Integer)buttonView.getTag();

above line gets the checkbox on which the check/uncheck event is performed. this way you would be able to find out the index.

thanks Amit Saxena for your suggestion. avail is a two dimensional array, and even after adding avail[i][j].setTag(i) i could printout the tag as suggested, kept returning null on click. and at the same time i still have a problem checking if the checkbox ischecked – jeffa.david Apr 15 '14 at 12:51
did you try (Integer)buttonView.getTag(); for getting the index ? later on you can use paranteView.findViewByTag(tag) to get the checkbox; – Amit Saxena Apr 15 '14 at 13:04
Yes i did, and it returns null. I tried it like this Integer k =(Integer)buttonView.getTag(); if(isChecked){ Toast.makeText(getApplicationContext(), "checkbox button : " + k, Toast.LENGTH_SHORT).show(); } – jeffa.david Apr 15 '14 at 13:09
Ooops, my bad, was setting the id instead of the Tag. I used avail[i][j].setTag(passed the 1st id of my cursor). I can now get the Tag of the selected index. I will appreciate if u can show me how to use the second way like u mentioned using paranteView.findViewByTag(tag) to get the checkbox; cheers bro – jeffa.david Apr 15 '14 at 13:30
Still waiting for your feedback. a little example from the code would be good to elaborate how to achieve the proposal... – jeffa.david Apr 16 '14 at 07:15
