相对布局权重 [英] RelativeLayout weight

问题描述

在布局资源 XML 中，我有 3 个位于主相对布局内的相对布局.视图将垂直显示.这 3 个 RelativeLayout() 彼此相邻设置，我希望它们填满整个屏幕，无论屏幕大小如何.我的布局视图:

In a layout resource XML, I have 3 RelativeLayout(s) which are inside a main RelativeLayout. The view will be shown vertically. These 3 RelativeLayout() are set next to each other, and I want them to fill the whole screen, doesnt matter what will be the screen size. My, layout view:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/backg"
 >

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginTop="@dimen/top_mr_image"
    android:src="@drawable/temp" />

<RelativeLayout
    android:id="@+id/r1"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_below="@+id/imageView1"
    android:layout_marginLeft="10dp"
    android:background="@drawable/r1bg"
    android:layout_weight="1"

     >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_marginLeft="@dimen/txt_mr_right"
        android:layout_marginRight="@dimen/txt_mr_right"
        android:layout_marginTop="39dp"
        android:text="S"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@id/textView1"
        android:layout_marginLeft="@dimen/txt_mr_right"
        android:layout_marginRight="@dimen/txt_mr_right"
        android:text="T"
        android:textAppearance="?android:attr/textAppearanceLarge" />
</RelativeLayout>

    <RelativeLayout
        android:id="@+id/r2"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignTop="@+id/r1"
        android:layout_toRightOf="@+id/r1"
        android:layout_weight="1" >
    </RelativeLayout>

            <RelativeLayout
        android:id="@+id/r3"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignTop="@+id/r2"
        android:layout_toRightOf="@+id/r2"
        android:layout_weight="1" >

    </RelativeLayout>

我为每个 relativeLayout 设置了 weight=1 和 layout_width=0dp 并且这种技术适用于按钮，我认为relativeLayout 也是如此，似乎我的想法是错误的.有什么想法吗?

I set weight=1 and layout_width=0dp for each relativeLayout and this technique works with buttons, I thought the same will be with relativeLayout, seems my thoughts were wrong. Any idea?

UPD1:我添加了我想要的图片

UPD1: I have added an image of what I would like to have

推荐答案

RelativeLayout 不关注android:layout_weight.(这是 LinearLayout.LayoutParams 的属性，但不是RelativeLayout.LayoutParams.)

RelativeLayout does not pay attention to android:layout_weight. (That's a property of LinearLayout.LayoutParams, but not of RelativeLayout.LayoutParams.)

您应该能够通过更简单的视图层次结构获得所需的布局.不清楚您要做什么，因为最后两个 RelativeLayout 是空的.如果您需要一个纯粹的垂直组织，我建议使用 LinearLayout 而不是 RelativeLayout.

You should be able to get the layout you want with a much simpler view hierarchy. It's not clear what you are trying to do, since the last two RelativeLayouts are empty. If you need a purely vertical organization, I'd suggest using LinearLayout instead of RelativeLayout.

EDIT 根据您的编辑，您似乎想要三个复合视图的水平布局，每个视图都可点击.我认为类似以下内容会起作用:

EDIT Based on your edit, it looks like you want a horizontal layout of three compound views, each one clickable. I think something like the following will work:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <!-- First column -->
    <LinearLayout
        android:id="@+id/firstColumn"
        android:orientation="vertical"
        android:gravity="center_horizontal"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        >

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="..." />
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:text="text 1"
            . . . />
    </LinearLayout>

    <!-- Second column -->
    <LinearLayout . . . >
        . . .
    </LinearLayout>
</LinearLayout>

如果按钮的内容不正确，您可以用 RelativeLayout 替换二级 LinearLayout 视图，如果这有助于更好地组织布局.

If the contents of the buttons aren't correct, you can replace the second-level LinearLayout views with RelativeLayout if that helps organize the layout better.
