    copied!<p>What I am trying to achieve is that, I am having an <code>ArrayList&lt; String > data = new ArrayList&lt; String >();</code> that contains values form 1 to 100. Now if I want to display this data in a scrollView then I will write the following code:</p> <pre><code>for(int i=0; i&lt;data.size(); i++) { View v = getLayoutInflator.inflate(R.layout.mycontainer, null); TextView tv = (TextView)v.findViewById(R.id.tv1); tv.setText(data.get(i)); layout.addView(v); } </code></pre> <p>The above code will display the data, but it may take some time to display all the data. What I want to do is that, I want to update the scrollView at every loop and display each row after the textview is added to the layout.</p> <p>Please check out <a href="https://play.google.com/store/apps/details?id=com.cleanmaster.mguard" rel="nofollow">this app</a> for the reference.</p> <p>This is the test code that I am doing to achieve what I want. Please have a look:</p> <pre><code>ListView list = (ListView)findViewById(R.id.listView1); ListAdapter adapter = new ListAdapter(this); list.setAdapter(adapter); for(int i=1; i&lt;=10; i++) { adapter.setData(String.valueOf(i)); adapter.notifyDataSetChanged(); } </code></pre> <p>Code for my ListAdapter:</p> <pre><code>public class ListAdapter extends BaseAdapter { private Context context; private int count; private ArrayList&lt;String&gt; data = new ArrayList&lt;String&gt;(); public ListAdapter(Context context) { this.context = context; } @Override public int getCount() { return count; } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } public void setData(String str) { data.add(str); count = data.size(); } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder; if(convertView == null) { LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = inflater.inflate(R.layout.test_layout, parent, false); holder = new ViewHolder(); holder.tv = (TextView)convertView.findViewById(R.id.textView1); convertView.setTag(holder); } else { holder = (ViewHolder)convertView.getTag(); } try { for(int i=0; i&lt;=data.size(); i++) { holder.tv.setText(data.get(i)); } } catch (Exception e) { e.printStackTrace(); } return convertView; } static class ViewHolder { TextView tv; } } </code></pre> <p>Thanks in advance Abhishek</p>
