随着文本大小的增加（多行）增加布局的长度

Question

我想增加aa的长度来增加绿线的高度（假设aa是7行左右的多线，那么绿线应该会自动增加），我已经尝试了我的努力但失败了，现在我没有更多的想法来实现上面提到的，以下是我的 xml 上面提到的布局，

//My root layout, which/who contain all the two child layouts(relative and linear layout)
<RelativeLayout android:layout_width="match_parent"
                android:layout_height="wrap_content">

   //Layout for image and line, here i want to increase the height of "profile_view_line(green line)" with increase in size of text "profile_tv_descriptionName"
    <RelativeLayout android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:id="@+id/profile_layout_relDescription">

        //This is the imageview,whose background is tranparent, so if i remove "layout below " property from "profile_view_line", then "profile_view_line" 
        //appear behind imageview(profile_img_description),which must/should not happen, but here i fail as well (as i don't want to appear this behind imageview)
        <ImageView android:id="@+id/profile_img_description"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/description_icon"
            android:layout_alignParentLeft="true"/>

            //This is the line to be expanded with increase in size of "profile_tv_descriptionName" but with minimum size of 30dp as height 
            //and must grow with the "profile_tv_descriptionName" if (profile_tv_descriptionName) is multi-line

            //i can't set property depending on "profile_tv_descriptionName"
            as it is in another viewgroup(relativeayout), due to which i can't set property on this one
        <View android:layout_below="@id/profile_img_description"
            android:layout_width="@dimen/1dp"
            android:id="@+id/profile_view_line"
            android:layout_height="@dimen/30dp"
            android:background="@color/colorGreen"
            android:layout_centerHorizontal="true" />
     </RelativeLayout>

     //Layout for description title and description text "aa" which exapnds as expected, here the dependincy is based on above maintained relative layout "profile_layout_relDescription"
    <LinearLayout android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="vertical"
                android:layout_toRightOf="@id/profile_layout_relDescription"
                android:layout_alignBottom="@id/profile_layout_relDescription">

        //This is the title, useless in this case but need for appearance
        <TextView
            android:id="@+id/profile_tv_description"
            android:text="@string/profile_description"
            android:textSize="@dimen/8dp"
            android:gravity="left"/>

         //this is the dependency factor which can increase and according to which "profile_view_line" green line must expand but i can't do 
         //that because it is in another viewgroup(linearlayout), due to which i can't set property on this one
        <TextView
            android:layout_height="wrap_content"
            android:id="@+id/profile_tv_descriptionName"
            android:text="Vikram"
            android:textSize="@dimen/13dp"
            android:gravity="left"/>
      </LinearLayout>
</RelativeLayout>

Answer 1

试试这样的布局：

<LinearLayout, horizontal>
    <LinearLayout, vertical, width wrap_content, height match_parent, gravity center_horizontal>
        <ImageView set width, set height>
        <View, greeen line, height 0, weight 1>
    </LinearLayout>
    <LinearLayout, vertical, width 0, height wrap_content, weight 1>
        <TextView title, wrap_content>
        <TextView description, wrap_content>
    </LinearLayout>
</LinearLayout>

解释：

一个正方形需要 4 个东西：

AB
CD

其中 A 是图像，B 是标题，C 是行，D 是文本。

B 和 D 需要彼此垂直对齐，并紧挨着 A 和 C，所以对我来说，每一对都应该采用垂直线性布局，然后这两对应该对齐一个水平的把它们排成一行。

A和C加起来有A的宽度，但是另外两个需要占剩下的space。这意味着宽度为 0，重量为 1。

现在我们有：

A B----------------------
C D----------------------

现在我们需要处理高度。 A 有一个固定的高度。 B 和 D 具有固定的高度，由其中的文本定义。这使得 C 的高度可变，占据了 space 的其余部分。所以我们说 AC 的高度匹配 parent，然后由 BD 的高度定义。然后 C 的高度为 0，重量为 1，使其填满所有剩余高度。这给了我们：

A B----------------------
C D----------------------
- -----------------------

随着文本大小的增加（多行）增加布局的长度

increase the length of layout with increase in size of text(multi-line)
