问题描述

。如下图我的code,我已经2 ImageView的,我想重叠,但更大的是系统地下文中较小的一个,无论是安卓layout_alignParentTop设置真,我认为这会导致重叠而Android保持dislaying它们下面的另一个。

 < RelativeLayout的机器人:ID =@ + ID / RelativeLayout1
        机器人:layout_width =WRAP_CONTENT机器人:layout_height =WRAP_CONTENT
        机器人:layout_gravity =center_vertical | CENTER_HORIZONTAL
        机器人:重力=CENTER_HORIZONTAL | center_vertical>
        < ImageView的机器人:ID =@ + ID / homeStars机器人:SRC =@绘制/背景
            机器人:layout_height =WRAP_CONTENT的android:layout_width =FILL_PARENT机器人:scaleType =centerInside
            机器人:layout_centerHorizo​​ntal =真正的机器人:layout_centerVertical =真正的机器人:layout_alignParentTop =真
            />
        < ImageView的机器人:ID =@ + ID / homeLogo机器人:SRC =@绘制/标志
            机器人:layout_height =WRAP_CONTENT的android:layout_width =220dip
            机器人:layout_alignParentTop =真正的机器人:layout_centerHorizo​​ntal =真
            机器人:paddingTop =2DIP/>
< / RelativeLayout的>

诺塔1:我不希望第一个被设置为相对于图的背景做。
诺塔2:我要补充,这相对布局是滚动型里面放


解决方案

 < RelativeLayout的
    机器人:ID =@ + ID / RelativeLayout1
    机器人:layout_width =WRAP_CONTENT
    机器人:layout_height =WRAP_CONTENT>    < ImageView的
        机器人:ID =@ + ID / homeStars
        机器人:layout_width =FILL_PARENT
        机器人:layout_height =WRAP_CONTENT
        机器人:scaleType =centerInside
        机器人:SRC =@绘制/背景/>    < ImageView的
        机器人:ID =@ + ID / homeLogo
        机器人:layout_width =220dip
        机器人:layout_height =WRAP_CONTENT
        机器人:paddingTop =2DIP
        机器人:SRC =@绘制/标志/>< / RelativeLayout的>

我删除了所有的你不同layout_ *标签和它工作正常。当然,所有的孩子将在一个 RelativeLayout的左上角自己的定位相互重叠。你是多余的标签被混淆不仅是我,但有可能的解析器。复制粘贴上述code和更改增量下一次! :)

As my code below shows, I've two ImageView that I would like to overlap but the bigger is systematically put below the smaller one, both is android:layout_alignParentTop set "true", I thought that would lead to an overlapping but Android keeps dislaying them one below the other.

<RelativeLayout android:id="@+id/RelativeLayout1"
        android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:layout_gravity="center_vertical|center_horizontal"
        android:gravity="center_horizontal|center_vertical">
        <ImageView android:id="@+id/homeStars" android:src="@drawable/background" 
            android:layout_height="wrap_content" android:layout_width="fill_parent" android:scaleType="centerInside" 
            android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:layout_alignParentTop="true"  
            />
        <ImageView android:id="@+id/homeLogo" android:src="@drawable/logo"
            android:layout_height="wrap_content" android:layout_width="220dip"
            android:layout_alignParentTop="true" android:layout_centerHorizontal="true"
            android:paddingTop="2dip" />
</RelativeLayout>

Nota 1 : I do not want the first one to be set as a background of the relative view. Nota 2 : I should add that this Relative Layout is put inside a ScrollView.

解决方案

<RelativeLayout
    android:id="@+id/RelativeLayout1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <ImageView
        android:id="@+id/homeStars"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:scaleType="centerInside"
        android:src="@drawable/background" />

    <ImageView
        android:id="@+id/homeLogo"
        android:layout_width="220dip"
        android:layout_height="wrap_content"
        android:paddingTop="2dip"
        android:src="@drawable/logo" />

</RelativeLayout>

I removed all of you're different layout_* tags and it works fine. Naturally all children will overlap each other by positioning themselves at the top left in a RelativeLayout. You're extra tags were confusing not only me but likely the parser. Copy paste the above code and make changes incrementally next time! :)
