    <p>I have list item with <code>EditText</code> in it, I don't know how many items there will be. I have a problem when I enter some text in <code>EditText</code>, and then scroll down a <code>ListView</code>, after I've scroll up again there is no text in my first <code>EditText</code>, or there is some text from other <code>EditText</code> from <code>ListView</code>.</p> <p>I've tried <code>TextWatcher</code>, and saving data to array, but problems is that returned position of view in <code>ListView</code> isn't always right, so I lost some data from array.</p> <p>Please help.</p> <p>Here is my code:</p> <pre><code>public class EfficientAdapter extends BaseAdapter { private LayoutInflater mInflater; public String[] Current; ArrayList&lt;String&gt; MeterName, PreviousReading, Current_Reading; JSONArray getArray_Meter_Reading; public EfficientAdapter(Context context, JSONArray getArray_Meter_Reading) { mInflater = LayoutInflater.from(context); this.getArray_Meter_Reading = getArray_Meter_Reading; MeterName = new ArrayList&lt;String&gt;(); PreviousReading = new ArrayList&lt;String&gt;(); for (int i = 0; i &lt; getArray_Meter_Reading.length(); i++) { try { String Meter_Name = getArray_Meter_Reading.getJSONObject(i) .getString("MeterName").toString(); String previous_Meter_Reading = getArray_Meter_Reading .getJSONObject(i).getString("PrevMeterReading") .toString(); MeterName.add(Meter_Name); PreviousReading.add(previous_Meter_Reading); // Meter[i]=MeterName.get(i); // Previous[i]=PreviousReading.get(i); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } public int getCount() { return getArray_Meter_Reading.length(); } public Object getItem(int position) { // TODO Auto-generated method stub return position; } public long getItemId(int position) { // TODO Auto-generated method stub return position; } public View getView(int position, View convertView, ViewGroup parent) { final ViewHolder holder; if (convertView == null) { convertView = mInflater.inflate(R.layout.meter_reading_list, null); holder = new ViewHolder(); holder.adp_MeterName = (TextView) convertView .findViewById(R.id.txt_Meter_Name); holder.adp_Previous = (TextView) convertView .findViewById(R.id.txt_Previous); holder.adp_Current = (EditText) convertView .findViewById(R.id.ed_Current); holder.adp_Current.addTextChangedListener(new TextWatcher() { public void onTextChanged(CharSequence s, int start, int before, int count) { } public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } public void afterTextChanged(Editable s) { Current[holder.ref] = s.toString(); } }); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } holder.ref = position; holder.adp_MeterName.setText(MeterName.get(position)); holder.adp_Previous.setText(PreviousReading.get(position)); // holder.adp_Current.setHint(MeterName.get(position)); // holder.adp_Current.setText(PreviousReading.get(position)); return convertView; } class ViewHolder { TextView adp_MeterName, adp_Previous; EditText adp_Current; int ref; } } </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
