Question

我正在创建一个具有固定底部面板的应用。每个面板的内容应显示在其上方的空白处。但每当我用一些内容填充身体时，内容溢出并与底部面板重叠。

填充后，它看起来像这样：

代码如下：

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

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.Lorem Ipsum is simply dummy text of the printing and typesetting industry.

P.S。：我知道提供相同功能的库，但使用它们会减少对我的应用程序的控制。

你必须像这样尝试，你不需要添加linerlayout作为textview的外部布局：

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

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
    android:layout_above="@id/bottompanel"
                android:text="Lorem Ipsum is simply dummy text of the printing and typesetting industry...."/>

        <LinearLayout

            android:layout_alignParentBottom="true"

Answer 2

有很多方法可以做到这一点

1）如果您的父布局是相对布局，仅适用于底栏设置属性

allignParentBottom="true"

你的另一个身体应该

android:layout_above="@+id/bottom_bar"

2）将您的父级布局设置为线性布局 orientation应该是垂直的并设置weightSum属性，例如weightSum = 6

并在您的正文布局中设置layoutHeight至0dp和weight至5 在您的底部栏高layoutHeight到0dp和weight到1 根据您的要求更改这些值

3）使用ConstraintLayout了解更多详情，请查看这些links和link

在父android:layout_above="@+id/bottompanel"中给出顶视图的位置，这样可以将文字保留在底部视图上方。
