In your XML, write this TextView:
在您的 XML 中，编写此 TextView：
<TextView
android:id="@+id/txtDetails"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="7"
android:scrollbars="vertical"
android:text="TextView"
/>
And in Activity, write this:
在 中Activity，写下这个：
TextView txtDetails = (TextView) findViewById(R.id.txtDetails);
txtDetails.setText("Your Text");
txtDetails.setMovementMethod(new ScrollingMovementMethod());
This will scroll the text in TextView. No need to write in ScrollView.
这将滚动 中的文本TextView。不需要写进去ScrollView。

Text getting cut off means what is the problem you are getting. Try the following code. It works.....
文本被截断意味着您遇到的问题是什么。试试下面的代码。有用.....
using xml code:
使用xml代码：
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="@+id/textView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="HERE I TOOK NEARLY 3-4 PAGES OF DOCUMENT. IT WORKED" />
</ScrollView>
If you are creating dynamically means, follow this code: main.java:

oncreate()
{
ScrollView sv=(ScrollView)findViewById(R.id.scrollView1);

sv.addView(tv);

android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ScrollView>

This will work, the trick is to get what you want to scroll inside the scrollview.
这会起作用，诀窍是在滚动视图中获取您想要滚动的内容。
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ScrollView
android:id="@+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/textView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="@string/text" />
</LinearLayout>
</ScrollView>
</RelativeLayout>
