android中Surfaceview挡住Animation的控件

[牛_弹琴]

在做一个android项目的时候需要使用摄像头当北京，在屏幕的下方有一些按钮，这些按钮有仿照Path的效果。所以布局的顶层用了一个FrameLayout，里面有一个SurfaceView用于显示摄像头背景，RelativeLayout用于管理按钮，在代码中为每个按钮增加了TranslateAnimation来移动按钮的位置，当调用Button的startAnimation时，按钮竟然都不见了


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

<SurfaceView
android:id="@+id/lo"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />

<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<Button
android:id="@+id/search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:background="@drawable/one" />

<Button
android:id="@+id/mycollect"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:background="@drawable/two" />

<Button
android:id="@+id/sending"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:background="@drawable/three" />

<Button
android:id="@+id/mypaopao"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:background="@drawable/four" />

<Button
android:id="@+id/setting"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:background="@drawable/five" />

<Button
android:id="@+id/menu"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:background="@drawable/menu" />
</RelativeLayout>

</FrameLayout>
