Question

I need help in creating a custom listview that allows me to have 2 strings/textviews per row. I have been researching a lot, but I cannot seem to understand how to do this. Any sample code and help would be appreciated. I know how to use simple_list_item_1, but not my own layout.
Thank YOU.
My (Still Non-Functioning) Code

 package com.painLogger;
 //ALL IMPORTS

 public class PainLoggerActivity extends Activity implements OnClickListener,
 OnKeyListener {

     /** Called when the activity is first created. */
     EditText txtItem;
     EditText txtItem2;
     Button btnAdd;
     ListView listItems;
     ArrayAdapter < String > aa;
     List < HashMap < String, String >> painItems = new ArrayList < HashMap < String, String >> ();
     int[] to;
     String[] from;
     SimpleAdapter adapter;


     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);

         txtItem = (EditText) findViewById(R.id.txtItem);
         txtItem2 = (EditText) findViewById(R.id.txtItem2);

         btnAdd = (Button) findViewById(R.id.btnAdd);
         listItems = (ListView) findViewById(R.id.listItems);

         btnAdd.setOnClickListener(this);

         from = new String[] {
             "row_1", "row_2"
         };
         to = new int[] {
             R.id.row1, R.id.row2
         };

         SimpleAdapter adapter = new SimpleAdapter(this, painItems, R.layout.mylistlayout,
             from, to);
         listItems.setAdapter(adapter);
     }

     private void addItem() {
         HashMap < String, String > map = new HashMap < String, String > ();

         map.put("row_1", txtItem.getText().toString());
         map.put("row_2", txtItem2.getText().toString());
         painItems.add(map);
         adapter.notifyDataSetChanged();
     }

     @Override
     public void onClick(View v) {
         if (v == this.btnAdd) {
             addItem();
         }
     }

     @Override
     public boolean onKey(View v, int keyCode, KeyEvent event) {

         if (event.getAction() == KeyEvent.ACTION_DOWN && keyCode ==
             KeyEvent.KEYCODE_DPAD_CENTER) {             this.addItem();

         }
         return false;
     }
 }

Answer 1

With reference to this question, use this code.
EDIT: Added hashmap definition

String[] from = new String[] {"row_1", "row_2"};
int[] to = new int[] { R.id.row1, R.id.row2};
List<HashMap<String, String>> fillMaps = new ArrayList<HashMap<String, String>>();

for (int j = 0; j < sourceObj.length(); j++) {
        HashMap<String, String> map = new HashMap<String, String>();
        map.put("row_1", sourceObj.data1);
        map.put("row_2", sourceObj.data2);
        fillMaps.add(map);
}

SimpleAdapter adapter = new SimpleAdapter(context, fillMaps, R.layout.yourlayoutname, from, to);
mListView.setAdapter(adapter);

• Make your list view which could be a LinearLayout with a couple of TextViews
• Reference this list layout using R.layout.yourlayoutname in this line SimpleAdapter adapter = new SimpleAdapter(context, fillMaps, R.layout.result, from, to);
• Pass in your data

The good thing about this approach is that it avoids you having to create any new objects, and it doesn’t involve much code.
