در این بازی یک صفحه تشکیل شده است که دارای 3 مرحله ساده و متوسط و سخت است که شما باید حباب را ضربه بزنید دقیقا بازی حباب که برای ضربه گیر وسایل برقی استفاده می شود این بازی شبیه سازی آن شده است.

ابتدا در مورد طراحی این اپ بگم که شما از یک گرید ویو برای قرار دادن آیتم ها استفاده می نمایید و داخل پوشه ی drawable از چند تا عکس استفاده می شود زمانی که حباب سالم است از عکس حباب سالم استفاده می کنید و زمانی که حباب را ضربه زدید از حباب که خراب شده است استفاده می کنید یعنی در وافع داخل گرید ویو ها از Imageview استفاده می کنید که با زدن هر کدام عکس تغییر می کند.

از پوشه ای raw هم برای صدا ضربه ی حباب ها استفاده می شود.

یک کلاس برای تعریف منوها داریم که سطح بازی را مشخص می کند

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

public class MainActivity extends Activity {

	BubbleGame game;

	public final static String EXTRA_MESSAGE = "com.example.bubblewrap.MESSAGE";

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		game = (BubbleGame) this.getApplication();
		game.initializeUi(this);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.activity_main, menu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		// Handle item selection
		switch (item.getItemId()) {
		case R.id.new_game:
			game.newGame(game.currentWrap);
			return true;
		case R.id.large_wrap:
			game.newGame(game.LARGE_WRAP);
			game.currentWrap = game.LARGE_WRAP;
			return true;
		case R.id.medium_wrap:
			game.newGame(game.MEDIUM_WRAP);
			game.currentWrap = game.MEDIUM_WRAP;
			return true;
		case R.id.small_wrap:
			game.newGame(game.SMALL_WRAP);
			game.currentWrap = game.SMALL_WRAP;

		default:
			return super.onOptionsItemSelected(item);
		}
	}

	/** Called when the user clicks the Send button */
	public void sendMessage(View view) {
		Intent intent = new Intent(this, DisplayMessageActivity.class);
		// EditText editText = (EditText) findViewById(R.id.edit_message);
		// String message = editText.getText().toString();
		// intent.putExtra(EXTRA_MESSAGE, message);
		startActivity(intent);

		// Do something in response to button
	}

}

کلاس دوم برای نمایش عکس هااستفاده می شود:

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;

public class ImageAdapter extends BaseAdapter {
	private Context mContext;
	private Integer[] bubble_images;

	public ImageAdapter(Context c, Integer[] bubble_images) {
		mContext = c;
		this.bubble_images = bubble_images;
	}

	public int getCount() {
		return bubble_images.length;
	}

	public Object getItem(int position) {
		return null;
	}

	public long getItemId(int position) {
		return 0;
	}

	// create a new ImageView for each item referenced by the Adapter
	public View getView(int position, View convertView, ViewGroup parent) {
		ImageView imageView;
		if (convertView == null) { // if it's not recycled, initialize some
									// attributes
			imageView = new ImageView(mContext);
			imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
			imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
			imageView.setPadding(0, 0, 0, 0);
		} else {
			imageView = (ImageView) convertView;
		}

		imageView.setImageResource(bubble_images[position]);
		return imageView;
	}

	// references to our images

}

کلاس بعدی برای نمایش پیغام ها در هر اکتیویتی است:

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.NavUtils;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;

public class DisplayMessageActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);

		// Get the message from the intent
		Intent intent = getIntent();
		String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);

		// Create the text view
		TextView textView = new TextView(this);
		textView.setTextSize(40);
		textView.setText(message);

		// Set the text view as the activity layout
		setContentView(textView);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.activity_display_message, menu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		switch (item.getItemId()) {
		case android.R.id.home:
			// This ID represents the Home or Up button. In the case of this
			// activity, the Up button is shown. Use NavUtils to allow users
			// to navigate up one level in the application structure. For
			// more details, see the Navigation pattern on Android Design:
			//
			// http://developer.android.com/design/patterns/navigation.html#up-vs-back
			//
			NavUtils.navigateUpFromSameTask(this);
			return true;
		}
		return super.onOptionsItemSelected(item);
	}

}

کلاس بعدی در مورد دریافت buble ها یا به عبارتی دریافت آیتم است.

public class BubbleWrap {

	private int numberOfBubbles;
	private int poppedBubbles;
	private Integer[] bubbles;

	/*
	 *Constructs a new BubbleWrap
	 *
	 *@param numberOfBubbles the number of bubbles
	 *@param bubble the resource id of unpopped bubble image
	 */
	public BubbleWrap(int numberOfBubbles, int bubble) {
		this.numberOfBubbles = numberOfBubbles;
		this.poppedBubbles = 0;
		this.bubbles = new Integer[numberOfBubbles];
		for (int i = 0; i < numberOfBubbles; i++) {
			bubbles[i] = bubble;
		}

	}
    
	/*
	 * Pops a bubble
	 * @param index the index of the bubble
	 * @param resource id of the image to replace with
	 */
	public void popBubble(int index, int bubble) {

		bubbles[index] = bubble;
		poppedBubbles++;
	}

	/*
	 * @return the number of popped bubbles
	 */
	public int getNumberOfPopped() {
		return poppedBubbles;
	}

	/*
	 * @return the number of bubbles
	 */
	public int getNumberOfBubbles() {
		return numberOfBubbles;
	}

	/*
	 * @return the bubbles
	 */
	public Integer[] getBubbles() {

		return bubbles;

	}

	/*
	 * 
	 * @param the index of a bubble
	 * @param the resource id of the image used
	 * 
	 * @return true if the bubble is not popped 
	 */
	public boolean isBubble(int index, int bubble) {
		if (bubbles[index] == bubble) {
			return true;
		}

		return false;
	}

}

و کلاس آخر هم تعریف تمام متغییر های استفاده شده است و منو های بازی و شروع بازی جدید از اول و تغییر دادن حباب ها است
