    <p>I am new so I may not explain the situation well. Please let me know if you need more info.</p> <p>I am trying to implement a listview like this:</p> <pre><code> [textview][button][checkbox] [textview][button][checkbox] [textview][button][checkbox] [textview][button][checkbox] </code></pre> <p>I　want other checkbox unchecked automatically when I click one of them. So it is like a single choice. I write following codes which can implement multiple choice but when I try to switch it to single choice I got trouble. </p> <p>in checkBoxOnClickListener I cannot find other (checkbox)view and toggle them. Any suggestion pals? Let me know if you think my express skills poor.</p> <p>Thank you.</p> <pre><code> public class MyAdapter extends SimpleAdapter { Map&lt;Integer, Boolean&gt; map; LayoutInflater mInflater; private List&lt;? extends Map&lt;String, ?&gt;&gt; mList; public MyAdapter(Context context, List&lt;Map&lt;String, String&gt;&gt; data, int resource, String[] from, int[] to) { super(context, data, resource, from, to); map = new HashMap&lt;Integer, Boolean&gt;(); mInflater = LayoutInflater.from(context); mList = data; for (int i = 0; i &lt; data.size(); i++) { map.put(i, false); } if (data.get(0).get("value").equals("Male") || data.get(0).get("value").equals("Yes")) { map.put(1, true); } } @Override public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { convertView = mInflater.inflate(R.layout.rapid_diagnosis_row, null); } TextView textView = (TextView) convertView.findViewById(R.id.multiple_question); textView.setText((String) mList.get(position).get("value")); CheckBox checkBox = (CheckBox) convertView.findViewById(R.id.multiple_checkbox); checkBox.setChecked(map.get(position)); // save position and checking status into tag checkBox.setTag(position); checkBox.setOnClickListener(checkBoxOnClickListener); return convertView; } public OnClickListener checkBoxOnClickListener = new OnClickListener() { public void onClick(View v) { // ((CheckBox) v).toggle(); boolean checked = ((CheckBox) v).isChecked(); if (checked) { ((CheckBox) v).setChecked(true); } else { ((CheckBox) v).setChecked(false); } int p = (Integer) (v.getTag()); mSimpleAdapter.map.put(p, checked); // this cannot works, helppp ListView lv = ((ListView) (v.getParent().getParent())); (CheckBox) cb = lv.findViewWithTag(1); cb.toggle(); ..................... </code></pre> <p>............... } }; }</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
