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:

[html] 
view plain
copy

 

  1. <?xml version="1.0" encoding="utf-8"?>
  2. <RelativeLayout android:layout_width="fill_parent"
  3. android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
  4. android:background="#ffffff">
  5. <ImageView android:layout_width="wrap_content"
  6. android:layout_height="fill_parent" android:background="@drawable/splash_shadow"
  7. android:layout_marginLeft="50dip" />
  8. <RelativeLayout android:id="@+id/relativeLayout_top_bar"
  9. android:layout_width="fill_parent" android:layout_height="40dip"
  10. android:background="@drawable/qa_bar">
  11. <ImageView android:layout_width="60dip"
  12. android:layout_height="20dip" android:background="@drawable/qa_logo"
  13. android:layout_centerInParent="true" />
  14. </RelativeLayout>
  15. <TextView android:layout_below="@id/relativeLayout_top_bar"
  16. android:layout_width="wrap_content" android:layout_height="wrap_content"
  17. android:textSize="20sp" android:text="Tap to Refresh"
  18. android:layout_centerHorizontal="true" android:layout_marginTop="50dip" android:textStyle="bold"/>
  19. <Button android:id="@+id/button_composer_sleep"
  20. android:layout_width="wrap_content" android:layout_height="wrap_content"
  21. android:background="@drawable/composer_sleep"
  22. android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
  23. android:layout_alignParentBottom="true">
  24. </Button>
  25. <Button android:id="@+id/button_composer_thought"
  26. android:layout_width="wrap_content" android:layout_height="wrap_content"
  27. android:background="@drawable/composer_thought"
  28. android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
  29. android:layout_alignParentBottom="true" android:layout_above="@id/button_composer_sleep">
  30. </Button>
  31. <Button android:id="@+id/button_composer_music"

  33. android:background="@drawable/composer_music"
  34. android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
  35. android:layout_alignParentBottom="true">
  36. </Button>
  37. <Button android:id="@+id/button_composer_place"
  38. android:layout_width="wrap_content" android:layout_height="wrap_content"
  39. android:background="@drawable/composer_place"
  40. android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
  41. android:layout_alignParentBottom="true" android:layout_above="@id/button_composer_music">
  42. </Button>
  43. <Button android:id="@+id/button_composer_with"
  44. android:layout_width="wrap_content" android:layout_height="wrap_content"
  45. android:background="@drawable/composer_with"
  46. android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
  47. android:layout_alignParentBottom="true" android:layout_above="@id/button_composer_place">
  48. </Button>
  49. <Button android:id="@+id/button_composer_camera"
  50. android:layout_width="wrap_content" android:layout_height="wrap_content"
  51. android:background="@drawable/composer_camera"
  52. android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
  53. android:layout_alignParentBottom="true" android:layout_above="@id/button_composer_with">
  54. </Button>
  55. <Button android:id="@+id/button_friends_delete"
  56. android:layout_width="wrap_content" android:layout_height="wrap_content"
  57. android:background="@drawable/friends_delete"
  58. android:layout_marginBottom="10dip" android:layout_marginLeft="10dip"
  59. android:layout_alignParentBottom="true" android:layout_above="@id/button_composer_camera">
  60. </Button>
  61. </RelativeLayout>

  250. }
  251. });
  252. animationTranslate.setDuration(durationMillis);
  253. return animationTranslate;
  254. }
  255. }

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。
