Making TextView scrollable on Android ?


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?


A1. 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">

    <ScrollView
        android:id="@+id/SCROLLER_ID"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:scrollbars="vertical"
        android:fillViewport="true">

        <TextView
            android:id="@+id/TEXT_STATUS_ID"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_weight="1.0"/>
    </ScrollView>

</LinearLayout>

A2. You can do your work by simply adding:

      android:scrollbars = "vertical"

     And, put this code in your Java class:

      textview.setMovementMethod(new ScrollingMovementMethod());

A3.  In Java

      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);



  XML Side:


    

  1.  <?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">
    <TextView
        android:id="@+id/tv_log"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:scrollbars="vertical"
        android:text="Log:" />
   </RelativeLayout>
    

    2. 




   JavaSide :


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

















A4.Add the following in the textview in XML.


























         android:scrollbars="vertical"



In the Java file.


        textView.setMovementMethod(new ScrollingMovementMethod());

















A5.The code below creates an automatic horizontal scrolling textview:



    TextView to xml use


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







    In Java


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