RelativeLayout - referencing ids within another nested view - is this possible?

问题

Is it possible to do something like this where TV2 is relative to TV1, where TV1 and TV2 are within different branches of the layout?

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <RelativeLayout
        android:id="@+id/RV1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

        <TextView
            android:id="@+id/TV01"
            android:layout_width="wrap_content"
            android:layout_height="50dp"
            android:text="test text" />
    </RelativeLayout>

    <RelativeLayout
        android:id="@+id/RV2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/RV1" >

        <TextView
            android:id="@+id/TV02"
            android:layout_width="wrap_content"
            android:layout_height="50dp"
            android:layout_toRightOf="@+id/TV01"  <--------- this references TV01 within the top RelativeView !!!
            android:text="other text" />
    </RelativeLayout>

</RelativeLayout>

in this example the statement android:layout_toRightOf="@+id/TV01" does not seem to work, since TV01 is within another RealtiveLayout branch than TV02.

Is there a way to somehow make references like this?

Many thanks!

回答1:

No, you cannot use RelativeLayout positioning like that. However:

You can combine RV1 and RV2

You can position RV2 to the right of RV1

回答2:

Is this a simplified example? or is this your actual layout. If the latter you should be able to achieve the same effect by changing rel2 to be like this:

<RelativeLayout
    android:id="@+id/RV2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/RV1"
    android:layout_toRightOf="@+id/RV1" >
