如何在RelativeLayout中将视图放置在另一个视图之上? [英] How to position a view on top of another view in RelativeLayout?

问题描述

我在RelativeLayout中有一个TextView(下面用绿色表示)和一个LinearLayout(下面用红色表示).我想将TextView放在LinearLayout的顶部，如下所示:

I have a TextView (indicated in green below) and a LinearLayout (indicated in red below) in a RelativeLayout. I want to position the TextView on top of the LinearLayout, like this:

但是，我尝试过:

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:id="@+id/linear_layout">
    <!--some other views-->
</LinearLayout>
<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true" <!--this because the textview is the topmost view on the screen so I tried to use this-->
    android:layout_alignLeft="@id/linear_layout"
    android:text="my text"
    android:textSize="10pt"
    android:id="@+id/text1"/>

但是，当我运行该应用程序时，它是这样的:

However, when I run the app, it is like this:

所以我想知道我做错了什么以及如何解决.我可以使用xml属性吗?

So I want to know what did I do wrong and how to fix it. Is there an xml attribute that I can use?

推荐答案

将LinearLayout放在TextView之后，如下所示:

Put your LinearLayout after TextView like this:

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true" <!-- this because the textview is the topmost view on the screen so I tried to use this -->
    android:text="my text"
    android:textSize="10pt"
    android:id="@+id/text1" />

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/text1"
    android:orientation="vertical"
    android:id="@+id/linear_layout">
    <!-- some other views -->
</LinearLayout>
