How to place an imageview on top of another imageview in android
提问by Coder_sLaY
This is my layout which i tried so far without any success
这是我迄今为止尝试过但没有任何成功的布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/white">
<LinearLayout
android:id="@+id/lltest"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_centerHorizontal="true">
<ImageView
android:id="@+id/inside_imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dip"
android:layout_marginBottom="5dip"
android:src="@drawable/frame"/>
</LinearLayout>
<ImageView
android:id="@+id/outside_imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="@id/inside_imageview"
android:scaleType="fitXY"/>
</RelativeLayout>
What i exactly want is to have my outside_imageview on top of inside_imageview with the exact height and width... How to do it through layout?
我真正想要的是将我的 outside_imageview 放在具有确切高度和宽度的 inside_imageview 之上......如何通过布局来做到这一点？

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/white" >
<ImageView
android:id="@+id/inside_imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="5dip"
android:layout_marginTop="5dip"
android:src="@drawable/frame" />
<ImageView
android:id="@+id/outside_imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="@id/inside_imageview"
android:layout_alignBottom="@id/inside_imageview"
android:layout_alignLeft="@id/inside_imageview"
android:layout_alignRight="@id/inside_imageview"
android:scaleType="fitXY" />
</RelativeLayout>
The layout_align[Top|Bottom|Left|Right]attribute in RelativeLayoutis used to align views based on their respective x and y values within the margin. The second ImageViewwill now be aligned to the top, bottom, left, and right of the first ImageViewbased on the margins. Padding is ignored in the alignment.
的layout_align[Top|Bottom|Left|Right]在属性RelativeLayout被用来基于所述内缘各自的x和y值对准意见。第二个ImageView现在将ImageView根据边距与第一个的顶部、底部、左侧和右侧对齐。在对齐中忽略填充。

FrameLayoutis what you need. You can simply merge the parent layout that is a FrameLayouttoo.
Take a look at the Android Developers Blog: http://android-developers.blogspot.it/2009/03/android-layout-tricks-3-optimize-by.html
FrameLayout是你所需要的。您可以简单地合并也是一个的父布局FrameLayout。看看Android 开发者博客：http: //android-developers.blogspot.it/2009/03/android-layout-tricks-3-optimize-by.html
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center">
<ImageView
android:id="@+id/outside_imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitXY"/>
<ImageView
android:id="@+id/inside_imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dip"
android:layout_marginBottom="5dip"
android:src="@drawable/frame" />
</merge>

You should try a FrameLayout. Inside a FrameLayout every Child is on top of each other.
你应该尝试一个FrameLayout. 在 FrameLayout 中，每个 Child 都在彼此之上。

Just add translation z and it will be on top, make sure the translation z is greater than the view you want to be on top of. Sorry for the late response.
只需添加平移 z 它将位于顶部，确保平移 z 大于您想要位于顶部的视图。回复晚了非常抱歉。
