如何将布局分为3个部分? [英] How to divide layout to 3 parts?

问题描述

我试图将布局划分为3个相等的行，尝试使用LinearLayout和权重，但是它不起作用，也没有任何改变:

I'm trying to divide my layout to 3 equal rows, trying to use LinearLayout and weights, but it doesn't work, it doesn't make any change:

<LinearLayout
    android:id="@+id/rightLayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_alignBottom="@+id/picture"
    android:layout_alignParentRight="true"
    android:layout_alignTop="@+id/picture"
    android:layout_toRightOf="@+id/aligner"
    android:orientation="vertical"
    android:weightSum="3" >

    <LinearLayout
        android:id="@+id/lay1"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:background="#00ff00" >

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="TextView" />
    </LinearLayout>

    <LinearLayout
        android:id="@+id/lay2"
        android:layout_width="fill_parent"
        android:layout_height="0dip"
        android:layout_weight="1" >

        <TextView
            android:id="@+id/TextView01"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="TextView" />
    </LinearLayout>

    <LinearLayout
        android:id="@+id/lay3"
        android:layout_width="fill_parent"
        android:layout_height="0dip"
        android:layout_weight="1" >

        <TextView
            android:id="@+id/TextView02"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="TextView" />
    </LinearLayout>

</LinearLayout>

推荐答案

起初，我没有意识到，这个问题并不存在.我有ScrollView，它使这些布局无法使用权​​重.我在ScrollView中添加了android:fillViewport="true"，它已修复.

At first, I didn't realise, that problem was not there. I had ScrollView and it made these layouts not work with weights. I added android:fillViewport="true" to ScrollView and it got fixed.
