以下是我的布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

</LinearLayout>

在运行应用程序时，包含按钮的底部线性布局不可见。只有滚动视图及其控件可见。

我认为你的xml设计很糟糕.scrollView通常在全屏使用你设置它的高度wrap_content所以如果内容很长时间会发生什么？把它改成像这样的东西

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#0A4152"
android:orientation="vertical" >

<ScrollView
    android:id="@+id/scrollViewRegister"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_above="@+id/lin"
    android:background="#0A4152" >

    <RelativeLayout
        android:id="@+id/layoutRegister"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:overScrollMode="never"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin" >

        <ImageButton
