我尝试将image(imageBottom)置于滚动view(scrollView)下方，但它与滚动视图的左下角重叠。

我还在layout_below中尝试了属性imageview，但这个技巧很有效。

创建相对布局并将textview和图像图标放在其中：

<RelativeLayout
    android:id="@+id/rl1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentTop="true"
   >

<TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/imageIcon"
        android:layout_centerHorizontal="true"
        android:gravity="center"
        android:text="@string/TextString"
        android:textSize="32sp" />

<ImageView
    android:id="@+id/imageIcon"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:contentDescription=""
    app:srcCompat="@drawable/course1" />
</RelativeLayout

在您的滚动视图中添加android:layout_above="@+id/imageBottom"和android:layout_below="@+id/rl1"

您只想滚动文本视图而不需要任何滚动视图，您可以像这样滚动textview：

只需设置

即可 
 android:maxLines = "AN_INTEGER"
 android:scrollbars = "vertical"

布局＆x文件中TextView的属性。

然后使用：

yourTextView.setMovementMethod(new ScrollingMovementMethod());
你的代码中的

。 并将android:layout_above="@+id/imageBottom"添加到textView，并android:layout_below="@+id/textView1"删除滚动视图布局

<TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView1"
        android:layout_centerHorizontal="true"
        android:layout_above="@+id/imageBottom"
        android:gravity="center"
        android:text="@string/TextString"
        android:textSize="32sp" />

试试这个。

<?xml version="1.0" encoding="utf-8"?>

    <TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/imageIcon"
        android:layout_centerHorizontal="true"
        android:gravity="center"
        android:text="hi"

        android:layout_above="@+id/imageBottom"

        android:layout_below="@+id/textView1"
        android:layout_marginBottom="30dp"
        android:layout_marginTop="10dp">

        <TextView

@Rohit Kumar你只需在滚动视图android:layout_above="@+id/imageBottom"和android:layout_below="@+id/textView1"

中添加此行 
<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:id="@+id/myLinearLayout"  
    android:layout_width="match_parent"  
    android:layout_height="match_parent"  
    android:orientation="vertical"  
    android:paddingBottom="@dimen/activity_vertical_margin"  
    android:paddingLeft="@dimen/activity_horizontal_margin"  
    android:paddingRight="@dimen/activity_horizontal_margin"  
    android:paddingTop="@dimen/activity_vertical_margin"  
    tools:context="com.example.rohitkumar.androidtutorial.MainActivity">  

    <TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/imageIcon"
        android:layout_centerHorizontal="true"
        android:gravity="center"
        android:text="Title"
        android:textSize="32sp" />

    <ScrollView
        android:id="@+id/scrollView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/imageBottom"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_below="@+id/textView1"
        android:layout_marginBottom="30dp"
        android:layout_marginTop="10dp">

        <TextView
            android:id="@+id/textView3"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="this is a simple paragraph that is meant to be nice and easy to type which is why there will be mommas no periods or any capital letters so i guess this means that it cannot really be considered a paragraph but just a series of run on sentences this should help you get faster at typing as im trying not to use too many difficult words in it although i think that i might start making it hard by including some more difficult letters I'm typing pretty quickly so forgive me for any mistakes i think that i will not just tell you a story about the time i went to the zoo and found"
            android:textSize="20sp" />

    </ScrollView>

    <ImageView
        android:id="@+id/imageIcon"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:contentDescription="test"
        app:srcCompat="@mipmap/ic_launcher" />

    <ImageView
        android:id="@+id/imageBottom"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:src="@mipmap/ic_launcher" />
