我在网上流传的代码基础上精简、整理出一个简单的类，我暂时把它命名为：Windows8TileImageView，即Windows 8磁贴(Tile)样式按钮，Windows8TileImageView其实就是继承于标准Android ImageView，单击该Windows8TileImageView有收缩、侧边收缩等比较有趣的效果。现在把Windows8TileImageView这个类的全部代码贴出来：

Windows8TileImageView使用方法很简单，和Android的ImageView类似，直接把它作为一个View使用。比如可以在布局文件中这样使用：

<?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:gravity="center"
        android:orientation="vertical" >
    
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical" >
    
            <LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:orientation="horizontal" >
    
                <LinearLayout
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:orientation="vertical" >
    
                    <windows8.tile.Windows8TileImageView
                        android:id="@+id/c_joke"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_margin="2dp"
                        android:scaleType="matrix"
                        android:src="@drawable/left_top" />
    
                    <windows8.tile.Windows8TileImageView
                        android:id="@+id/c_idea"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_margin="2dp"
                        android:scaleType="matrix"
                        android:src="@drawable/left_bottom" />
                </LinearLayout>
    
                <windows8.tile.Windows8TileImageView
                    android:id="@+id/c_constellation"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_margin="2dp"
                    android:scaleType="matrix"
                    android:src="@drawable/right" />
            </LinearLayout>
    
            <windows8.tile.Windows8TileImageView
                android:id="@+id/c_recommend"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_margin="2dp"
                android:scaleType="matrix"
                android:src="@drawable/bottom" />
        </LinearLayout>
    
    </LinearLayout>

说明：此布局文件中的 android:src加载的drawable资源图片是自己选取的，具体使用时候可以根据自身情况设置。

可以为控件Windows8TileImageView增加单击事件，比如这样添加：

package windows8.tile;
    
    import android.support.v7.app.ActionBarActivity;
    import android.widget.Toast;
    import android.os.Bundle;
    
    public class MainActivity extends ActionBarActivity {
    
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_main);
    
    		Windows8TileImageView joke = (Windows8TileImageView) findViewById(R.id.c_joke);
    
    		// 为某一个磁贴添加点击事件的方式。
    		joke.setOnClickIntent(new Windows8TileImageView.OnViewClick() {
    
    			@Override
    			public void onClick() {
    				Toast.makeText(getApplicationContext(), "磁贴的点击事件",
    						Toast.LENGTH_LONG).show();
    			}
    		});
    	}
    }
