(Android)求助！界面的布局

Question

如图所示：怎样将ImageSwitcher布满整个屏幕呢，换句话说将ImageSwitcher当作背景图显示？
    程序的运行顺序：
    首先，填充GridView（GridView里面是相册）；
    其次，填充Gallery（Gallery里面是该相册的所有缩略图）；
    最后，将缩略图的原图显示在ImageSwitcher上。
PS：图片的数据都是通过URL获得的。
最后对大家说声谢谢！

Answer 1

<LinearLayout android:id="@+id/layout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">    <LinearLayout android:id="@+id/layout2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:orientation="horizontal">
        此处放你的ImageSwitcher
   </LinearLayout>    <LinearLayout android:id="@+id/layout3"
android:layout_width="fill_parent"
android:layout_height="你的Gallery的高度"
android:orientation="horizontal">
        此处放你的Gallery
   </LinearLayout></LinearLayout>

Answer 2

不是这样的，我需要将ImageSwitcher控件布局整个屏幕，也就是将ImageSwitcher当作背景图片，将上面的GridView与下面的Gallery都显示在ImageSwitcher上面。
谢谢你的答复哦！

Answer 3

你把原来.xml文件发上来看看。

不好意思，现在才回复你，请见谅。xml文件如下：<?xml version="1.0" encoding="utf-8"?>

    </RelativeLayout>
</LinearLayout>

Answer 5

View相互覆盖，用：
FrameLayout !

Answer 6

界面里面的控件都不是独立存在的，界面上部分我叫它是相册，相册还有相架，相架由两个ImageView组成，可以看代码。如果你说FrameLayout布局可以实现，麻烦你贴上核心的布局方式。感激不尽！
我的想法是怎样将ImageSwither设置为背景，或者放在所有的控件背后。可能是我想错了吧，呵呵。

试试看<?xml version="1.0" encoding="utf-8"?>

Answer 8

不行，会报错。
你说有没有可能和程序加载部件的顺序有关系。
LogCat提示的错误如下所示：
08-03 17:10:48.528: E/AndroidRuntime(2517): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.photographic.ui/com.photographic.ui.BrowseAlbum}: java.lang.ClassCastException: android.widget.ProgressBar
08-03 17:10:48.528: E/AndroidRuntime(2517): Caused by: java.lang.ClassCastException: android.widget.ProgressBar
在你原有的基础上修改了，还是报同样的错误。程序的运行顺序：
    首先，填充GridView（GridView里面是相册）；
    其次，填充Gallery（Gallery里面是该相册的所有缩略图）；
    最后，将缩略图的原图显示在ImageSwitcher上。
麻烦帮忙再看看，谢谢啦！

Answer 9

呵呵，解决了，心情好开心啊，谢谢你们两位的帮忙。
心得是分析布局一定要想清楚每种布局的用途，如果代码长，先看最里面的Layout，再逐层往外看。
最终的代码如下：<?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"
    android:orientation="vertical"
    android:background="@drawable/internalbg">
    
    
    <RelativeLayout android:id="@+id/relative_album"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="64px"
            android:layout_marginLeft="3dp"
            android:layout_marginTop="84dp"
            android:orientation="vertical" >            <ImageView
                android:layout_width="627px"
                android:layout_height="18px"
                android:src="@drawable/table_top" />            <ImageView
                android:layout_width="629px"
                android:layout_height="46px"
                android:src="@drawable/table_under" />
        </LinearLayout>
        
        <HorizontalScrollView
            android:id="@+id/galleryScroll"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:focusable="false"
            android:scrollbars="none" >            <FrameLayout
                android:layout_width="wrap_content"
                android:layout_height="fill_parent"
                android:focusable="false" >                <LinearLayout
                    android:id="@+id/linear_id"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"

                    </GridView>
                </LinearLayout>
            </FrameLayout>
        </HorizontalScrollView>
        
        <Gallery android:id="@+id/images_gallery"

            android:layout_alignParentBottom="true"
            android:gravity="center_vertical"/>
    
    </RelativeLayout>
    
    
    <ImageSwitcher android:id="@+id/imageswitcher"

            <ProgressBar android:id="@+id/progress_imageswitcher"

Answer 10

测试布局是否正确的方法：新建一个Activitiy，只留个onCreate里面的setContentView(R.layout.布局文件名);
