textView.setText("some text ");             
textView.setSelected(true);

public class CustomTextView extends TextView {
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}

@Override
protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
if(focused)
super.onFocusChanged(focused, direction, previouslyFocusedRect);
}
@Override
public void onWindowFocusChanged(boolean focused) {
if(focused)
 super.onWindowFocusChanged(focused);
}
@Override
public boolean isFocused() {
return true;
}

}

You have to use android:scrollbars = "horizontal" in xml file, then use

tv.setMovementMethod(new ScrollingMovementMethod()); 

in your java code.
