thanx for watching my example
MAIN JAVA CLASS
ListView2Activity .java
package com.listview;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
public class ListView2Activity extends Activity implements OnItemClickListener
{
/** Called when the activity is first created. */
ListView lview;
ListViewAdapter lviewAdapter;
private final static String month[] = {"January","February","March","April","May",
"June","July","August","September","October","November","December"};
private final static String number[] = {"Month - 1", "Month - 2","Month - 3",
"Month - 4","Month - 5","Month - 6",
"Month - 7","Month - 8","Month - 9",
"Month - 10","Month - 11","Month - 12"};
private final static String sayings[]={"Hunger","Rain","Love","Sex","Summer","poverty","Autum","what","yelling","News","Terror","Snow"};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
lview = (ListView) findViewById(R.id.listView2);
lviewAdapter = new ListViewAdapter(this, month, number);
System.out.println("adapter => "+lviewAdapter.getCount());
lview.setAdapter(lviewAdapter);
lview.setOnItemClickListener(this);
}
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long id) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), month[position]+"\t is the month of \t"+sayings[position], Toast.LENGTH_LONG).show();
//Toast.makeText(this,"Title => "+month[position]+"=> n Description"+number[position], Toast.LENGTH_SHORT).show();
}
}
here is the list view adapter that extends the Baseadapter class to handle the images
package com.listview;
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class ListViewAdapter extends BaseAdapter
{
Activity context;
String title[];
String description[];
public ListViewAdapter(Activity context, String[] title, String[] description) {
super();
this.context = context;
this.title = title;
this.description = description;
}
public int getCount() {
// TODO Auto-generated method stub
return title.length;
}
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
private class ViewHolder {
TextView txtViewTitle;
TextView txtViewDescription;
ImageView image;
TextView quotes;
}
public View getView(int position, View convertView, ViewGroup parent)
{
// TODO Auto-generated method stub
ViewHolder holder;
LayoutInflater inflater = context.getLayoutInflater();
if (convertView == null)
{
convertView = inflater.inflate(R.layout.listitem_row, null);
holder = new ViewHolder();
holder.txtViewTitle = (TextView) convertView.findViewById(R.id.textView1);
holder.txtViewDescription = (TextView) convertView.findViewById(R.id.textView2);
holder.image=(ImageView)convertView.findViewById(R.id.imageView1);
holder.quotes=(TextView)convertView.findViewById(R.id.quotes);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.txtViewTitle.setText(title[position]);
holder.txtViewDescription.setText(description[position]);
holder.image.setBackgroundResource(images[position]);
holder.quotes.setText(sayings[position]);
//holder.image.setImageResource(R.drawable.ic_launcher);
return convertView;
}
private final static String sayings[]={"Hunger","Rain","Love","Sex","Summer","poverty","Autum","what","yelling","News","Terror","Snow"};
private Integer[] images={R.raw.brightday,R.drawable.ic_launcher,R.raw.sunlaugh,R.raw.stormcloud,R.raw.hotsun,R.raw.brightday,R.raw.eveningcloud,R.raw.cloudlove,R.raw.springs,R.raw.stormcloud,R.raw.xmas,R.raw.cloudwhite};
}
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:layout_height="wrap_content"
android:id="@+id/listView2"
android:layout_width="match_parent">
</ListView>
</LinearLayout>
then the custom xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
android:textAppearance="?android:attr/textAppearanceLarge" >
</TextView>
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" >
</TextView>
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/quotes"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Large Text"
android:layout_marginLeft="200dp"
android:layout_marginBottom="100dp"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
