android - How to use button in activity to jump to information in same activity? -

I would like to know whether it is possible to make a button in the activity to jump to scroll weave according to the information given below. Sort like:

  Button 1 button 2 button 3 paragraph 1 paragraph 2 paragraph 3  

So when the button selects 1, you start the paragraph In 1 further, this does not have to scroll down to user relevant paragraphs / information or to start a new activity. (To move related information on the same page as many pages with titles at the top on the page.)

OK, I have tried sofar:

  Last View Routeview = Inflator.In Flat (R. Late Fragment_SNnex, Container, False); Button Button = (Button) rootView.findViewById (R.id.Button1); button.setOnClickListener (New OnClickListener () {public void onClick (final scene v) {mScrollView = (scrollview) rootView.findViewById (R.string.TextView1); mScrollView.smoothScrollTo (R.id.TextView1, 0);}}) ;  

Then I get this error:

  11-05 09: 28: 43.722: E / Android time (30741): java.lang.NullPointerException 11 - 05 09: 28: 43.722: e / AndroidRuntime (30741): 28 :: 43.722: e / AndroidRuntime (30741): Android com.test.testpark.StestFragment $ 1.onClick (StestFragment.java:34) 11-05 In September, view.View.performClick (see.Java 4637) 11-05 09: 28: 43.722: E / Android Random (30741): On Android.

, but easily scroll rather than immediately.

Parameter: Position x where to scroll the Y position on the X axis to scroll on the Y axis

Then you can use the TextView id (R.id.TextView1) ), But the text view status, something like this:

  See the final view Rootview = Inflator. In flat (R.layout.fragment_snakes, container, false); Button Button = (Button) rootView.findViewById (R.id.Button1); TextView paragraph 1 = (TextView) RouteviewFindViewID (RaidTextView1); ScrollView scrollView = (ScrollView) rootView.findViewById (R.id.ScrollView); Button.setOnClickListener (New OnClickListener) {Click Public Zero (see last v) {scrollView.smoothScrollTo (0, paragraph 1.getTop ());}});
