如何在RelativeLayout中设置相同的高度？

Question

Below is my xml code:

<RelativeLayout
    android:id="@+id/ib"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:gravity="center" >

    <ImageButton
        android:id="@+id/button_icon"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
    <TextView
        android:id="@+id/tv"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_toLeftOf="@+id/ib"
        android:gravity="center"
        android:text="Large Text"
        android:textAppearance="?android:attr/textAppearanceLarge" />
</RelativeLayout>

The ImageButton ib and TextView tw has different height.
I want the ib and tv had the same height.
That is if height of ib > tv, then set the height of tv same as ib.
If else, then set the height of ib same as tv.
How can I do it?

Answer 1

将android:layout_alignBottom="@+id/button_icon"属性添加到textview

Answer 2

使用LinearLayout并将ImageButton高度设置为"wrap_content" ，将TextView设置高度设置为"fill_parent" 。

Answer 3

You will need to make the height of ImageButton is "wrap_content" and have the TextView just "fill_parent" . You will need to have them both wrapped in a layout parent. That way they are associated with the same layout parent.

Put your elements into LinearLayout, set layout_width="match_parent" and add properties "layout_weight"="1"

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="sample text"/>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="sample text"/>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="sample text"/>
    </LinearLayout>
