超炫button按鈕動畫效果

         

  今天從網上看到一個這樣的效果，感覺很有創意，自己也搜集了一些資料，仿照著實現了一下。

    下面就直接上源碼：

    首先看一下布局檔案：

<?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"></Button></RelativeLayout>

其實就是在button點擊的時候播放Tween動畫。

這樣就基本完成，參照上面的代碼 自己也可以自行修改成自己喜歡的樣式。

看一下在我手機上啟動並執行效果：
