Customlistview with same image Part-1. 
In this example we set a different image for all list items.

Let's go for coding:

CREATE NEW ANDROID PROJECT

We need for this example:
1) activity_main.xml (...res/layout/ )
2) mylist.xml (...res/layout/ )
3) MainActivity.java
4) CustomListAdapter.java

Step 1: Write code into activity_main.xml
This is a main activity where we put list view.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </ListView>

</LinearLayout>

Step 2: Write code into mylist..xml
Created custom view for listview to show with image and text in list view.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/icon"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:padding="5dp" />

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/item"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:layout_marginTop="5dp"
            android:padding="2dp"
            android:text="Medium Text"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="#0000aa" />

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:text="TextView" />
    </LinearLayout>

</LinearLayout>

Step 3: Write code into MainActivity.java

package dev.androidapplink.customlistviewapp_2;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.Toast;

public class MainActivity extends Activity {
// create variable
ListView list;
//define string for List item(s)
String[] itemname = { "pic1", "pic2", "pic3", "pic4", "pic5", "pic6",
"pic7", "pic8" };
//set image according to list item(s) from drawable
Integer[] imgid = { R.drawable.pic1, R.drawable.pic2, R.drawable.pic3,
R.drawable.pic4, R.drawable.pic5, R.drawable.pic6, R.drawable.pic7,
R.drawable.pic8, };

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//create adapter and bind item name with image id
CustomListAdapter adapter = new CustomListAdapter(this, itemname, imgid);
list = (ListView) findViewById(R.id.list);
list.setAdapter(adapter);
//implement on item click listener to show toast on click but you can put here your operation as your requirement of app
list.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
String Slecteditem = itemname[+position];
// make your operation here i make toast.

Toast.makeText(getApplicationContext(), Slecteditem,
Toast.LENGTH_SHORT).show();

}
});
}

}

Step 4: Write code into CustomListAdapter.java
CustomListAdapter.java is a custom list adapter class which provides data to list view.
package dev.androidapplink.customlistviewapp_2;

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;

public class CustomListAdapter extends ArrayAdapter<String> {

private final Activity context;
private final String[] itemname;
private final Integer[] imgid;

public CustomListAdapter(Activity context, String[] itemname,
Integer[] imgid) {
super(context, R.layout.mylist, itemname);
// TODO Auto-generated constructor stub

this.context = context;
this.itemname = itemname;
this.imgid = imgid;
}

public View getView(int position, View view, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View rowView = inflater.inflate(R.layout.mylist, null, true);

TextView txtTitle = (TextView) rowView.findViewById(R.id.item);
ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
TextView extratxt = (TextView) rowView.findViewById(R.id.textView1);

txtTitle.setText(itemname[position]);
imageView.setImageResource(imgid[position]);
extratxt.setText("Description " + itemname[position]);
return rowView;
};

}
