仿ZAKER的windows phone風格主界面

使用了ZAKER到最新版本，其主界面採用windows phone的風格，感覺還蠻好看的，挺喜歡的，就模仿寫了一下，實現到界面截圖如下：

第一版面：

第二版面：

在實現了它到九宮格菜單，還實現了背景圖片到緩慢移動效果。

首先來分析一下它到整個佈局架構，我們肯定知道它必須是採用到FrameLayout佈局，最下面到是背景圖片視圖，上面的是線性佈局來裝下左右兩個面板，左邊到是一個可以滾動的容器，右邊放一個頁碼和四個按鈕。

那麼怎麼實現背景圖片的不斷循環滾動呢？既然是顯示圖片的，那麼自然離不開ImageView，所以在這裏我們自定義一個MyImageView，它來繼承ImageView，在它裏面通過使用Handler消息處理機制+Timer計時器來控制圖片的顯示位置。

在這裏，我使用了android.support.v4.view.ViewPager來實現可滑動到宮格菜單，自定義一個MyPagerAdapter繼承PagerAdapter，在instantiateItem方法中配置顯示參數。

大概原理就是這樣，挺簡單的，下面分享一下代碼吧：

工程目錄結構：

一. src/com/example/zakerdemo下面的類：

MainActivity.java:

public class MainActivity extends Activity {
	ArrayList<ImageInfo> data; // 菜單數據
	private static TextView mynum; // 頁碼

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		mynum = (TextView) findViewById(R.id.mynum);
		// 初始化數據
		initData();
		ViewPager vpager = (ViewPager) findViewById(R.id.vPager);
		vpager.setAdapter(new MyPagerAdapter(MainActivity.this, data));
		vpager.setPageMargin(50);
		vpager.setOnPageChangeListener(new OnPageChangeListener() {

			@Override

				mynum.setText("" + (int) (arg0 + 1));
