How to use ScrollView in Android?

Question

I have an XML layout file, but the text is more than fits into the screen size. What do I need to do in order to make a ScrollView?

Answer 1

How to use ScrollView

Using ScrollView is not very difficult. You can just add one to your layout and put whatever you want to scroll inside. ScrollView only takes one child so if you want to put a few things inside then you should make the first thing be something like a LinearLayout.

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <!-- things to scroll -->

    </LinearLayout>
</ScrollView>

If you want to scroll things horizontally, then use a HorizontalScrollView.

Making the content fill the screen

As is talked about in this post, sometimes you want the ScrollView content to fill the screen. For example, if you had some buttons at the end of a readme. You want the buttons to always be at the end of the text and at bottom of the screen, even if the text doesn't scroll.

If the content scrolls, everything is fine. However, if the content is smaller than the size of the screen, the buttons are not at the bottom.

This can be solved with a combination of using fillViewPort on the ScrollView and using a layout weight on the content. Using fillViewPort makes the ScrollView fill the parent area. Setting the layout_weight on one of the views in the LinearLayout makes that view expand to fill any extra space.

Here is the XML

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">                        <--- fillViewport

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <TextView
            android:id="@+id/textview"
            android:layout_height="0dp"                <--- 
            android:layout_weight="1"                  <--- set layout_weight
            android:layout_width="match_parent"
            android:padding="6dp"
            android:text="hello"/>

        <LinearLayout
            android:layout_height="wrap_content"       <--- wrap_content
            android:layout_width="match_parent"
            android:background="@android:drawable/bottom_bar"
            android:gravity="center_vertical">

            <Button
                android:layout_width="0dp"
                android:layout_weight="1"
                android:layout_height="wrap_content"
                android:text="Accept" />

            <Button
                android:layout_width="0dp"
                android:layout_weight="1"
                android:layout_height="wrap_content"
                android:text="Refuse" />

        </LinearLayout>
    </LinearLayout>
</ScrollView>

Answer 2

As said above you can put it inside a ScrollView... and if you want the Scroll View to be horizontal put it inside HorizontalScrollView... and if you want your component (or layout) to support both put inside both of them like this:

  <HorizontalScrollView>
        <ScrollView>
            <!-- SOME THING -->
        </ScrollView>
    </HorizontalScrollView>

and with setting the layout_width and layout_height ofcourse.

Answer 3

Put your TableLayout inside a ScrollView Layout.That will solve your problem.

Answer 4

There are two options. You can make your entire layout to be scrollable or only the TextView to be scrollable.

For the first case,

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

        <TableLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:stretchColumns="1" >

            <TableRow>

                <ImageView
                    android:id="@+id/imageView"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_marginLeft="5dip"
                    android:layout_marginRight="5dip"
                    android:layout_marginTop="10dip"
                    android:src="@drawable/icon"
                    android:tint="#55ff0000" >
                </ImageView>
            </TableRow>

            <TableRow>

                <TextView
                    android:id="@+id/name"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:padding="3dip"
                    android:text="  Name " >
                </TextView>

                <TextView
                    android:id="@+id/name1"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:gravity="left"
                    android:text="Veer" >
                </TextView>
            </TableRow>

            <TableRow>

                <TextView
                    android:id="@+id/age"

                    android:text="  Age" >

            <Relativelayout>
            </Relativelayout>
        </TableLayout>
    </RelativeLayout>

</ScrollView>

or, as I said you can use scrollView for TextView alone.

Answer 5

A ScrollView is a special type of FrameLayout in that it allows users to scroll through a list of views that occupy more space than the physical display.I just add some attributes .

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:fillViewport="true"
     android:scrollbars = "vertical"
     android:scrollbarStyle="insideInset"
    >
    <TableLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:stretchColumns="1"
        >
        <!-- Add here which you want -->
    </TableLayout>

</ScrollView>

Answer 6

To scroll data in text view you can use this to your text view. and add and for anything other layout you can just add scroll view on layout as people are saying above.

/** android:scrollable=true at textview in xml layout.

TextView txtScroll = (TextView) findViewById(R.id.txt1);
        txtScroll.setMovementMethod(new ScrollingMovementMethod());
