    copied!<p>I am using an example to show a list view with an image and text. It is taking too much time when the list is shown. So what I want is to use the this list as a lazy image list so that all of the images are not loaded right away, but are loaded as users scroll down.</p> <pre><code>public class SetImageText { public int icon; public String title; public SetImageText() { super(); } public SetImageText(int icon,String title) { super(); this.icon=icon; this.title=title; } } //Main Class package com.example.customizearrayadapter; import android.R.layout; public class MainActivity extends Activity { private ListView listView1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); SetImageText data[]=new SetImageText[] { new SetImageText(R.drawable.limage,"Cloudy"), new SetImageText(R.drawable.limage,"Showers"), new SetImageText(R.drawable.limage,"snow"), new SetImageText(R.drawable.limage,"Storm"), new SetImageText(R.drawable.limage,"Sunny"), new SetImageText(R.drawable.cow, "kriss"), new SetImageText(R.drawable.dog,"wazid"), new SetImageText(R.drawable.hen, "anuj"), new SetImageText(R.drawable.horse, "abhay"), new SetImageText(R.drawable.kbc, "abid"), new SetImageText(R.drawable.mj ,"aman"), new SetImageText(R.drawable.penguine ,"ali"), new SetImageText(R.drawable.rat, "hemant"), new SetImageText(R.drawable.pizza, "jai"), new SetImageText(R.drawable.tortoise ,"kapil") }; SetImageTextArrayAdapter adapter=new SetImageTextArrayAdapter(this,R.layout.listview_row_item,data); listView1=(ListView)findViewById(R.id.listView1); View header=(View)getLayoutInflater().inflate(R.layout.listview_header,null); listView1.addHeaderView(header); listView1.setAdapter(adapter); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } package com.example.customizearrayadapter; import java.util.Set; import android.app.Activity; import android.content.Context; public class SetImageTextArrayAdapter extends ArrayAdapter&lt;SetImageText&gt;{ Context context; int layoutResourceId; SetImageText data[]=null; public SetImageTextArrayAdapter(Context context, int layoutResourceId, SetImageText[] data) { super(context, layoutResourceId, data); this.layoutResourceId=layoutResourceId; this.context=context; this.data=data; // TODO Auto-generated constructor stub } public View getView(int position,View convertView,ViewGroup parent) { View row = convertView; SetImageTextHolder holder = null; if(row == null) { LayoutInflater inflater = ((Activity)context).getLayoutInflater(); row = inflater.inflate(layoutResourceId, parent, false); holder = new SetImageTextHolder(); holder.imgIcon = (ImageView)row.findViewById(R.id.imgIcon); holder.txtTitle = (TextView)row.findViewById(R.id.txtTitle); row.setTag(holder); } else { holder = (SetImageTextHolder)row.getTag(); } SetImageText setimagetext = data[position]; holder.txtTitle.setText(setimagetext.title); holder.imgIcon.setImageResource(setimagetext.icon); return row; } static class SetImageTextHolder { ImageView imgIcon; TextView txtTitle; } } </code></pre>
