    <p>try this:</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 static HashMap&lt;Integer,String&gt; myList=new HashMap&lt;Integer,String&gt;(); 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(); } } // initialize myList for(int i=0;i&lt;JSON_ARRAY_LENGTH;i++) { myList.put(i,""); } } 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; final int pos=position; 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); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } 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(); myList.put(pos,s.toString.trim()); } }); 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)); holder.adp_Current.setText(myList.get(position)); return convertView; } class ViewHolder { TextView adp_MeterName, adp_Previous; EditText adp_Current; int ref; } } </code></pre> <p>Here I have included a HashMap object which will keep an eye on if EditText contains value or not.And when you scroll the listview,it will be rendered again by calling its getView method along with the text associated with each edittext.</p> <p>In this code,when you firstly load listview,all your edittext will be with no text.once you enter some text,it will be noted in myList.So when you again render the list,your text would be prevented.</p> <p>One more thing,you should implement textwatcher outside if(convertView==null)..else.. block.That's a better practice!</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.

SQuiL has stopped working due to an internal error.

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