This is how I did it purely in XML:

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical"android:layout_width="fill_parent"android:layout_height="fill_parent"><ScrollViewandroid:id="@+id/SCROLLER_ID"android:layout_width="fill_parent"android:layout_height="wrap_content"android:scrollbars="vertical"android:fillViewport="true"><TextViewandroid:id="@+id/TEXT_STATUS_ID"android:layout_width="fill_parent"android:layout_height="fill_parent"android:layout_weight="1.0"/></ScrollView></LinearLayout>

NOTES:

1. android:fillViewport="true" combined with android:layout_weight="1.0" will make the textview take up all available space.

2. When defining the Scrollview, DO NOT specify android:layout_height="fill_parent" otherwise the scrollview doesn't work! (this has caused me to waste an hour just now! FFS).

PRO TIP:

To programmatically scroll to the bottom after appending text, use this:

mTextStatus = (TextView) findViewById(R.id.TEXT_STATUS_ID);mScrollView = (ScrollView) findViewById(R.id.SCROLLER_ID);private void scrollToBottom(){mScrollView.post(new Runnable(){public void run(){mScrollView.smoothScrollTo(0, mTextStatus.getBottom());}});}

All that is really necessary is the setMovementMethod(). Here's an example using a LinearLayout.

File main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical"android:layout_width="fill_parent"android:layout_height="fill_parent"><TextViewandroid:id="@+id/tv1"android:layout_width="fill_parent"android:layout_height="fill_parent"android:text="@string/hello"/></LinearLayout>

File WordExtractTest.java

public class WordExtractTest extends Activity {TextView tv1;/** Called when the activity is first created. */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);tv1 = (TextView)findViewById(R.id.tv1);loadDoc();}private void loadDoc() {String s = "";for(int x=0; x<=100; x++) {s += "Line: " + String.valueOf(x) + "\n";}tv1.setMovementMethod(new ScrollingMovementMethod());tv1.setText(s);}}

Make your textview just adding this

TextView textview= (TextView) findViewById(R.id.your_textview_id);textview.setMovementMethod(new ScrollingMovementMethod());

It is not necessary to put in

android:Maxlines="AN_INTEGER"`

You can do your work by simply adding:

android:scrollbars = "vertical"

And, put this code in your Java class:

textview.setMovementMethod(new ScrollingMovementMethod());

You can either

1. surround the TextView by a ScrollView; or
2. set the Movement method to ScrollingMovementMethod.getInstance();.

The best way I found:

Replace the TextView with an EditText with these extra attributes:

android:background="@null"android:editable="false"android:cursorVisible="false"

There is no need for wrapping in a ScrollView.

Simple. This is how I did it:

1. XML Side:

   <?xml version="1.0" encoding="utf-8"?><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"android:paddingLeft="@dimen/activity_horizontal_margin"android:paddingRight="@dimen/activity_horizontal_margin"tools:context="com.mbh.usbcom.MainActivity"><TextViewandroid:id="@+id/tv_log"android:layout_width="match_parent"android:layout_height="wrap_content"android:scrollbars="vertical"android:text="Log:" /></RelativeLayout>

2. Java side:

   tv_log = (TextView) findViewById(R.id.tv_log);tv_log.setMovementMethod(new ScrollingMovementMethod());

Bonus:

To let the text view scroll down as the text fill it, you have to add:

 android:gravity="bottom"

to the TextView xml file. It will scroll down automatically as more text comes in.

Of course you need to add the text using the append function instead of set text:

 tv_log.append("\n" + text);

I used it for Log purpose.

I hope this helps ;)

This is "How to apply ScrollBar to your TextView", using only XML.

First, you need to take a Textview control in the main.xml file and write some text into it ... like this:

<TextViewandroid:id="@+id/TEXT"android:layout_height="wrap_content"android:layout_width="wrap_content"android:text="@string/long_text"/>

Next, place the text view control in between the scrollview to display the scroll bar for this text:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical"android:layout_height="wrap_content"android:layout_width="fill_parent"><ScrollViewandroid:id="@+id/ScrollView01"android:layout_height="150px"android:layout_width="fill_parent"><TextViewandroid:id="@+id/TEXT"android:layout_height="wrap_content"android:layout_width="wrap_content"android:text="@string/long_text"/></ScrollView></RelativeLayout>

That's it...

If you use Kotlin , in this way :XML

 <TextViewandroid:id="@+id/tvMore"android:layout_width="match_parent"android:layout_height="wrap_content"android:maxLines="3"android:scrollbars="vertical" />

Activity

tvMore.movementMethod = ScrollingMovementMethod()

This will provide smooth scrolling text with a scroll bar.

ScrollView scroller = new ScrollView(this);TextView tv = new TextView(this);tv.setText(R.string.my_text);scroller.addView(tv);

The "pro tip" above from Someone Somewhere (Making TextView scrollable on Android) works great, however, what if you're dynamically adding text to the ScrollView and would like to automatically scroll to the bottom after an append only when the user is at the bottom of the ScrollView? (Perhaps because if the user has scrolled up to read something you don't want to automatically reset to the bottom during an append, which would be annoying.)

Anyway, here it is:

if ((mTextStatus.getMeasuredHeight() - mScrollView.getScrollY()) <=(mScrollView.getHeight() + mTextStatus.getLineHeight())) {scrollToBottom();}

The mTextStatus.getLineHeight() will make it so that you don't scrollToBottom() if the user is within one line from the end of the ScrollView.

In kotlin for making the textview scrollable

myTextView.movementMethod= ScrollingMovementMethod()

and also add in xml this property

 android:scrollbars = "vertical"

If you want text to be scrolled within the textview, then you can follow the following:

First you should have to subclass textview.

And then use that.

Following is an example of a subclassed textview.

public class AutoScrollableTextView extends TextView {public AutoScrollableTextView(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);setEllipsize(TruncateAt.MARQUEE);setMarqueeRepeatLimit(-1);setSingleLine();setHorizontallyScrolling(true);}public AutoScrollableTextView(Context context, AttributeSet attrs) {super(context, attrs);setEllipsize(TruncateAt.MARQUEE);setMarqueeRepeatLimit(-1);setSingleLine();setHorizontallyScrolling(true);}public AutoScrollableTextView(Context context) {super(context);setEllipsize(TruncateAt.MARQUEE);setMarqueeRepeatLimit(-1);setSingleLine();setHorizontallyScrolling(true);}@Overrideprotected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {if(focused)super.onFocusChanged(focused, direction, previouslyFocusedRect);}@Overridepublic void onWindowFocusChanged(boolean focused) {if(focused)super.onWindowFocusChanged(focused);}@Overridepublic boolean isFocused() {return true;}}

Now, you have to use that in the XML in this way:

 <com.yourpackagename.AutoScrollableTextViewandroid:layout_width="fill_parent"android:layout_height="wrap_content"android:text="This is very very long text to be scrolled"/>

That's it.

Add the following in the textview in XML.

android:scrollbars="vertical"

And finally, add

textView.setMovementMethod(new ScrollingMovementMethod());

in the Java file.

I didn't find TextView scrolling to support the 'fling' gesture, where it continues scrolling after a flick up or down. I ended up implementing that myself because I didn't want to use a ScrollView for various reasons, and there didn't seem to be a MovementMethod that both allowed me to select text and click on links.

When you are done with scrollable, add this line to the view's last line when you enter anything in the view:

((ScrollView) findViewById(R.id.TableScroller)).fullScroll(View.FOCUS_DOWN);

yourtextView.setMovementMethod(new ScrollingMovementMethod());

you can scroll it now.

If you don't want to use the EditText solution then you might have better luck with:

@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.yourLayout);(TextView)findViewById(R.id.yourTextViewId).setMovementMethod(ArrowKeyMovementMethod.getInstance());}

Add this to your XML layout:

android:ellipsize="marquee"android:focusable="false"android:marqueeRepeatLimit="marquee_forever"android:scrollHorizontally="true"android:singleLine="true"android:text="To Make An textView Scrollable Inside The TextView Using Marquee"

And in code you have to write the following lines:

textview.setSelected(true);textView.setMovementMethod(new ScrollingMovementMethod());

I know this is an older post, but this is how I am handling the issue on the Java side.

 // Allow textView to scrolltv.setSingleLine(true);tv.setHorizontallyScrolling(true);tv.setEllipsize(TextUtils.TruncateAt.MARQUEE);tv.setMarqueeRepeatLimit(-1); // Infinite// TextView must be 'selected'tv.setSelected(true);// Padding not necessary, but this helps so the text isn't right// up against the side of a screen/layouttv.setPadding(10, 0, 10, 0);

The code below creates an automatic horizontal scrolling textview:

While adding TextView to xml use

<TextView android:maxLines="1" android:ellipsize="marquee"android:scrollHorizontally="true"/>

Set the following properties of TextView in onCreate()

tv.setSelected(true);tv.setHorizontallyScrolling(true); 

I had this problem when I was using TextView inside the ScrollView. This solution has worked for me.

scrollView.setOnTouchListener(new View.OnTouchListener() {@Overridepublic boolean onTouch(View v, MotionEvent event) {description.getParent().requestDisallowInterceptTouchEvent(false);return false;}});description.setOnTouchListener(new View.OnTouchListener() {@Overridepublic boolean onTouch(View v, MotionEvent event) {description.getParent().requestDisallowInterceptTouchEvent(true);return false;}});

Use it like this

<TextView android:layout_width="match_parent" android:layout_height="match_parent" android:maxLines = "AN_INTEGER"android:scrollbars = "vertical"/>

Put maxLines and scrollbars inside TextView in xml.

<TextView android:layout_width="wrap_content"android:layout_height="wrap_content"android:scrollbars="vertical"android:maxLines="5" // any number of max line here./>

Then in java code.

textView.setMovementMethod(new ScrollingMovementMethod());

whenever you need to use the ScrollView as parent, And you also use the scroll movement method with TextView.

And When you portrait to landscape your device that time occur some issue. (like) entire page is scrollable but scroll movement method can't work.

if you still need to use ScrollView as parent or scroll movement method then you also use below desc.

If you do not have any problems then you use EditText instead of TextView

see below :

<EditTextandroid:id="@+id/description_text_question"android:layout_width="match_parent"android:layout_height="wrap_content"android:background="@null"android:editable="false"android:cursorVisible="false"android:maxLines="6"/>

Here, the EditText behaves like TextView

And your issue will be resolved

In my case.Constraint Layout.AS 2.3.

Code implementation:

YOUR_TEXTVIEW.setMovementMethod(new ScrollingMovementMethod());

XML:

android:scrollbars="vertical"android:scrollIndicators="right|end"

I struggled with this for over a week and finally figured out how to make this work!

My issue was that everything would scroll as a 'block'. The text itself was scrolling, but as a chunk rather than line by line. This obviously didn't work for me, because it would cut off lines at the bottom. All of the previous solutions did not work for me, so I crafted my own.

Here is the easiest solution by far:

Make a class file called: 'PerfectScrollableTextView' inside a package, then copy and paste this code in:

import android.content.Context;import android.graphics.Rect;import android.util.AttributeSet;import android.widget.TextView;public class PerfectScrollableTextView extends TextView {public PerfectScrollableTextView(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);setVerticalScrollBarEnabled(true);setHorizontallyScrolling(false);}public PerfectScrollableTextView(Context context, AttributeSet attrs) {super(context, attrs);setVerticalScrollBarEnabled(true);setHorizontallyScrolling(false);}public PerfectScrollableTextView(Context context) {super(context);setVerticalScrollBarEnabled(true);setHorizontallyScrolling(false);}@Overrideprotected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {if(focused)super.onFocusChanged(focused, direction, previouslyFocusedRect);}@Overridepublic void onWindowFocusChanged(boolean focused) {if(focused)super.onWindowFocusChanged(focused);}@Overridepublic boolean isFocused() {return true;}}

Finally change your 'TextView' in XML:

From: <TextView

To: <com.your_app_goes_here.PerfectScrollableTextView

XML - You can use android:scrollHorizontally Attribute

Whether the text is allowed to be wider than the view (and therefore can be scrolled horizontally).

May be a boolean value, such as "true" or "false".

Prigramacaly - setHorizontallyScrolling(boolean)

Try this:

android:scrollbars = "vertical"
