    copied!<p>first, i'm sorry for my bad english and, maybe, for my stupid issues (i'm newbie). I want to implement an option panel formatted as a title. So here my code:</p> <p><strong>listview_item_row.xml</strong></p> <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp"&gt; &lt;ImageView android:id="@+id/imgIcon" android:contentDescription="option image" android:layout_width="wrap_content" android:layout_height="wrap_content" /&gt; &lt;TextView android:id="@+id/txtText" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_toRightOf="@id/imgIcon" android:paddingLeft="15dp" android:textSize="20sp" /&gt; &lt;TextView android:id="@+id/txtSubText" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_toRightOf="@id/imgIcon" android:layout_below="@id/txtText" android:paddingLeft="15dp" android:textSize="14sp" /&gt; &lt;CheckBox android:id="@+id/checkBox" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toRightOf="@id/txtText" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p><strong>Row.java</strong></p> <pre><code> public class Row { public int icon; public String text; public String subtext; public Row(){ super(); } public Row(int icon, String text ,String subtext) { super(); this.icon = icon; this.text = text; this.subtext = subtext; } } </code></pre> <p><strong>RowAdapter.java</strong></p> <pre><code> public class RowAdapter extends ArrayAdapter&lt;Row&gt;{ Context context; int layoutResourceId; Row data[] = null; public RowAdapter(Context context, int layoutResourceId, Row[] data) { super(context, layoutResourceId, data); this.layoutResourceId = layoutResourceId; this.context = context; this.data = data; } @Override public View getView(int position, View convertView, ViewGroup parent) { View myRow = convertView; RowHolder holder = null; if(myRow == null) { LayoutInflater inflater = ((Activity)context).getLayoutInflater(); myRow = inflater.inflate(layoutResourceId, parent, false); holder = new RowHolder(); holder.imgIcon = (ImageView)myRow.findViewById(R.id.imgIcon); holder.txtText = (TextView)myRow.findViewById(R.id.txtText); holder.txtSubText = (TextView)myRow.findViewById(R.id.txtSubText); holder.checkBox = (CheckBox)myRow.findViewById(R.id.checkBox); myRow.setTag(holder); } else { holder = (RowHolder)myRow.getTag(); } Row row = data[position]; holder.txtText.setText(row.text); holder.imgIcon.setImageResource(row.icon); holder.txtSubText.setText(row.subtext); return myRow; } static class RowHolder { ImageView imgIcon; TextView txtText; TextView txtSubText; CheckBox checkBox; } } </code></pre> <p>At now i dont show any checkbox when i start the activity even if i've inflate it. How can i fix this?</p> <p>Also, if I may take advantage from this question, when I have to implement the onClickListener for checkboxes how can i understand WHICH checkbox was clicked? I'll do something like this:</p> <pre><code>... Row row = data[position]; holder.txtText.setText(row.text); holder.imgIcon.setImageResource(row.icon); holder.txtSubText.setText(row.subtext); holder.check..setOnCheckedChangeListener(new OnCheckedChangeListener() { public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if ( isChecked ) { // my code here } } }); ... </code></pre> <p>I think that "position" is the key but i dont know how can i use it.</p>
