Android LinearLayout background Image
提问by user3141985
I'm having a problem with my view if I try to display an image as background, it took the whole space and the second child of linear layout (2 RelativeLayout that appears next to each other) does not appear into view.
如果我尝试将图像显示为背景，我的视图就会出现问题，它占用了整个空间，并且线性布局的第二个子项（2 个彼此相邻的相对布局）不会出现在视图中。
How can I set image as background keeping other layout elements above it ?
如何将图像设置为背景，并在其上方保留其他布局元素？

<RelativeLayout

android:layout_height="wrap_content"

It is a bit late, but my problem was solved with the following code.
有点晚了，但我的问题已通过以下代码解决。
Used the ImageViewto set my background image and then displayed the linear layout over it.
使用ImageView来设置我的背景图像，然后在其上显示线性布局。
<?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" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:contentDescription="@string/my_msg"
android:src="@drawable/my_super_bg_image" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/top_style"
android:orientation="vertical" >
<RelativeLayout
android:id="@+id/today"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="5dp"
android:paddingRight="5dp" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:text="some text here"
android:textSize="24sp" />
</RelativeLayout>
</LinearLayout>
</FrameLayout>
If some one needs to know more, I will update the answer.

You have to use android:backgroundproperty instead having an ImageView.
您必须使用android:background属性而不是ImageView.
