Question

我的应用程序中有一个ScrollView，在其中我创建了一个包含各种元素的线性布局，但问题是我底部的按钮显示不正确。它们在底部被切断。我使用了填充和边距但没有发生任何事情。下面是我的布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent"
android:background="@color/light_gray">

    </LinearLayout>

</ScrollView>


<ProgressBar
    android:id="@+id/pBar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:visibility="gone" />

有人能建议我错过了吗？

Answer 1

在LinearLayout下填写另一个ScrollView并提供

paddingBottom到第二个孩子（第二个LinearLayout）

所以将此添加到添加的 linearLayout： -

 android:paddingBottom="20dp"

填充的正确顺序： -

  ScrollView
     ||
    LinearLayout X- X -- > padding Bottom wont be applied  
          ||
        LinearLayout with paddingBottom -- > is applicable

注意： - paddingBottom和marginBottom无法应用于ScrollView的直接子项。

Answer 2

删除

$.when.apply($, promises).then(...);

Answer 3

只需添加android：paddingBottom =＆＃34; @ dimen / dp30＆＃34;进入你的LinearLayout：

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/light_gray">

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/dp10">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginLeft="@dimen/dp20"
        android:layout_marginRight="@dimen/dp20"
        android:layout_marginTop="@dimen/dp30"
        android:orientation="vertical"
        android:paddingBottom="@dimen/dp30">

在ScrollView底部剪切布局
