Making TextView scrollable on Android

Question

I am displaying text in a textview that appears to be too long to fit into one screen. I need to make my TextView scrollable. How can I do that?

Here is the code:

final TextView tv = new TextView(this);
tv.setBackgroundResource(R.drawable.splash);
tv.setTypeface(face);
tv.setTextSize(18);
tv.setTextColor(R.color.BROWN);
tv.setGravity(Gravity.CENTER_VERTICAL| Gravity.CENTER_HORIZONTAL);
tv.setOnTouchListener(new OnTouchListener() {
    public boolean onTouch(View v, MotionEvent e) {
        Random r = new Random();
        int i = r.nextInt(101);
        if (e.getAction() == e.ACTION_DOWN) {
            tv.setText(tips[i]);
            tv.setBackgroundResource(R.drawable.inner);
        }
        return true;
    }
});
setContentView(tv);

Answer 1

Make your textview just adding this

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

Answer 2

In my case.Constraint Layout.AS 2.3.

Code implementation:

YOUR_TEXTVIEW.setMovementMethod(new ScrollingMovementMethod());

XML:

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

Answer 3

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 :

<EditText
     android: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

Answer 4

Use it like this

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

Answer 5

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());

Answer 6

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());
