Two XML files, one for main screen, one for custom dialog.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
 
    <Button
        android:id="@+id/buttonShowCustomDialog"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Show Custom Dialog" />
 
</LinearLayout>

File : res/layout/custom.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
 
    <ImageView
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="5dp" />
 
    <TextView
        android:id="@+id/text"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textColor="#FFF" 
        android:layout_toRightOf="@+id/image"/>/>
 
     <Button
        android:id="@+id/dialogButtonOK"
        android:layout_width="100px"
        android:layout_height="wrap_content"
        android:text=" Ok "
        android:layout_marginTop="5dp"
        android:layout_marginRight="5dp"
        android:layout_below="@+id/image"
        />
 
</RelativeLayout>

Read the comment and demo in next step, it should be self-explorary.
File : MainActivity.java

package com.mkyong.android;

import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;

public class MainActivity extends Activity {
 
	final Context context = this;
	private Button button;
 
	public void onCreate(Bundle savedInstanceState) {
 
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
 
		button = (Button) findViewById(R.id.buttonShowCustomDialog);
 
		// add button listener
		button.setOnClickListener(new OnClickListener() {
 
		  @Override
		  public void onClick(View arg0) {
 
			// custom dialog
			final Dialog dialog = new Dialog(context);
			dialog.setContentView(R.layout.custom);
			dialog.setTitle("Title...");
 
			// set the custom dialog components - text, image and button
			TextView text = (TextView) dialog.findViewById(R.id.text);
			text.setText("Android custom dialog example!");
			ImageView image = (ImageView) dialog.findViewById(R.id.image);
			image.setImageResource(R.drawable.ic_launcher);
 
			Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
			// if button is clicked, close the custom dialog
			dialogButton.setOnClickListener(new OnClickListener() {
				@Override
				public void onClick(View v) {
