title: How to let a TextView scroll automatically vertically when the text exceeds the TextView size?
body: <p>I'm trying to have an auto scroll Text-view vertically when video is playing. My text is too long to fit the screen and I want to auto scroll it when activity started. I followed every tutorial or tips posted here on stack-overflow but I couldn't figure out. </p>
  
  <h2>Here my class file:</h2>
  
  <pre><code>public class TextSrcollActivity extends Activity {
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_text_srcoll);
  
      TextView tv=(TextView)findViewById(R.id.textView1);
      tv.setMovementMethod(new ScrollingMovementMethod());
      tv.setSelected(true);
  }
  
  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
      // Inflate the menu; this adds items to the action bar if it is present.
      getMenuInflater().inflate(R.menu.text_srcoll, menu);
      return true;
  }
  }
  </code></pre>
  
  <h2>And here is my XML file:</h2>
  
  <pre><code>&lt;LinearLayout
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:layout_marginRight="3dp"
  android:layout_marginTop="3dp"
  android:background="#ff737373"
  android:gravity="center"
  android:minWidth="64dp"
  android:orientation="vertical"
  android:padding="3dp" &gt;
  &lt;TextView
      android:id="@+id/textView1"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:ellipsize="marquee"
      android:focusable="true"
      android:focusableInTouchMode="true"
      android:marqueeRepeatLimit="marquee_forever"
      android:maxWidth="100px"
      android:scrollHorizontally="false"
      android:scrollbars="vertical"
      android:gravity="bottom"
      android:singleLine="false"
      android:textColor="#ffd9d9d9"
      android:textSize="16sp"/&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>In the XML file, I tried to change some properties but I still have nothing. </p>
