title: Android: get access to view elements in OnClickListener
body: <p>I have a Fragment container and some buttons outside the fragment which interact with the content of the fragment. When I click on the button, I need to get the information inside the text elements. This is what I have right now, but it doesn't work.
  The code comes from the fragment pager demos.</p>
  
  <pre><code>Button bm = (Button) findViewById(R.id.bm);
  bm.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
      EditText editTextIn1 = (EditText) v.findViewById(R.id.editTextIn1);
    }
  });
  </code></pre>
  
  <p>edit
  I use this sample:</p>
  
  <pre><code>http://developer.android.com/reference/android/support/v13/app/FragmentStatePagerAdapter.html
  
  public class FragmentStatePagerSupport extends FragmentActivity {
      static final int NUM_ITEMS = 10;
  
      MyAdapter mAdapter;
  
      ViewPager mPager;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.fragment_pager);
  
          mAdapter = new MyAdapter(getSupportFragmentManager());
  
          mPager = (ViewPager)findViewById(R.id.pager);
          mPager.setAdapter(mAdapter);
  
          // Watch for button clicks.
          Button button = (Button)findViewById(R.id.goto_first);
          button.setOnClickListener(new OnClickListener() {
              public void onClick(View v) {
                  mPager.setCurrentItem(0);
              }
          });
