RelativeLayout和高度百分比.无法使用layout_below和layout_weight [英] RelativeLayout and height percentage. Unable to use layout_below and layout_weight

问题描述

我对relativelayout有一个问题，它的子级可以使用layout_below和layout_weight设置其百分比高度.

I have a problem with relativelayout where its children could use layout_below and layout_weight to set its percentage height.

例如，我们有一个相对的布局，并且在里面有三个带有textviews的线性布局.现在，我想为其中三个设置(linearlayouts)相对布局总高度的25.50,25％的高度.我该怎么办?

For example, we have a relative layout and inside of it we have three linear layouts with textviews. Now, I would like to set for three of them (linearlayouts) 25,50,25 % of height of total height of relative layout. How could I accomplish it?

我找到了> weight_sum和relativelayout的解决方案(点击)，但不使用layout_below.

I found a solution for weight_sum and and relativelayout (CLICK), but it doesn't use layout_below.

我该如何解决?

我尝试在所有linearlayouts内添加其他linearlayout，但是后来我无法使用layout_below.

I tried to add additional linearlayout inside of all linearlayouts, but then I am unable use layout_below.

这是概念图片的想法:

这是我的代码:

<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_below="@+id/linlay_leftcol_notification_header" >

    <LinearLayout
        android:id="@+id/linlay_leftcol_clock_theday"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" >

    <TextView
        android:id="@+id/tv_theday"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="@string/theday"
        android:textColor="#FFFFFF" />
    </LinearLayout>

    <LinearLayout
        android:id="@+id/linlay_leftcol_clock_thetime"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/linlay_leftcol_clock_theday" >

        <TextView
            android:id="@+id/tv_thetime"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="@string/thetime"
            android:textColor="#FFFFFF" />
    </LinearLayout>

    <LinearLayout
        android:id="@+id/linlay_leftcol_clock_thenumber_themonth_theyear"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/linlay_leftcol_clock_thetime" >

        <TextView
            android:id="@+id/tv_thenumberofday_themonth_theyear"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="@string/thenumberofday_themonth_theyear"
            android:textColor="#FFFFFF" />
    </LinearLayout>
</RelativeLayout>
