《Android实现Windows 8磁贴(Tile)样式按钮》
效果图如下:
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(); } }); } }
