超炫button按钮动画效果

今天从网上看到一个这样的效果，感觉很有创意，自己也搜集了一些资料，仿照着实现了一下。

下面就直接上源码：

首先看一下布局文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:layout_width="fill_parent"
	android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
	android:background="#ffffff">

	<ImageView android:layout_width="wrap_content"
		android:layout_height="fill_parent" android:background="@drawable/splash_shadow"
		android:layout_marginLeft="50dip" />

	<RelativeLayout android:id="@+id/relativeLayout_top_bar"
		android:layout_width="fill_parent" android:layout_height="40dip"
		android:background="@drawable/qa_bar">

		<ImageView android:layout_width="60dip"
			android:layout_height="20dip" android:background="@drawable/qa_logo"
			android:layout_centerInParent="true" />

	</RelativeLayout>

	<TextView android:layout_below="@id/relativeLayout_top_bar"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:textSize="20sp" android:text="Tap to Refresh"
		android:layout_centerHorizontal="true" android:layout_marginTop="50dip" android:textStyle="bold"/>


	<Button android:id="@+id/button_composer_sleep"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:background="@drawable/composer_sleep"
		android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
		android:layout_alignParentBottom="true">
	</Button>

	<Button android:id="@+id/button_composer_thought"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:background="@drawable/composer_thought"
		android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
		android:layout_alignParentBottom="true" android:layout_above="@id/button_composer_sleep">
	</Button>

	<Button android:id="@+id/button_composer_music"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:background="@drawable/composer_music"
		android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
		android:layout_alignParentBottom="true">
	</Button>

	<Button android:id="@+id/button_composer_place"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:background="@drawable/composer_place"
		android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
		android:layout_alignParentBottom="true" android:layout_above="@id/button_composer_music">
	</Button>


	<Button android:id="@+id/button_composer_with"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:background="@drawable/composer_with"
		android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
		android:layout_alignParentBottom="true" android:layout_above="@id/button_composer_place">
	</Button>


	<Button android:id="@+id/button_composer_camera"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:background="@drawable/composer_camera"
		android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
		android:layout_alignParentBottom="true" android:layout_above="@id/button_composer_with">
	</Button>


	<Button android:id="@+id/button_friends_delete"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:background="@drawable/friends_delete"
		android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
		android:layout_alignParentBottom="true" android:layout_above="@id/button_composer_camera">

</RelativeLayout>

其实就是在button点击的时候播放Tween动画。

这样就基本完成，参照上面的代码 自己也可以自行修改成自己喜欢的样式。
