SetOnClickListener (nuevo OnClickListener () no funciona en Fragment

Estoy trabajando en fragmentos de NAVigation Drawer. Andi copiar el código de Actividad a fragmentos para ejecutar en fragmento. He hecho eso, el diseño es visible, pero ninguna de las acciones del botón funciona bajo esa actividad de fragmentos.

¿Puedes decirme qué hice mal?

• ¿Debo usar AppCompat v7 si minsdk es 14
• Android: cuando / por qué debo usar FrameLayout en lugar de Fragment?
• Circular ViewPager que utiliza FragmentPagerAdapter
• División de texto a través de múltiples TextViews / Fragmentos con ViewPager
• Cómo mantener fragmentos en la memoria en el cambio de orientación

FragmentTwo.java

public class FragmentTwo extends Fragment { Button blog,fb,twitter,mail; ImageView dateimg; private boolean snet; public FragmentTwo() { } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view=inflater.inflate(R.layout.contact_lay,container, false); System.out.println("Kaks7"); dateimg = (ImageView) getActivity().findViewById(R.id.img); blog= (Button) getActivity().findViewById(R.id.btnGplus); fb = (Button) getActivity().findViewById(R.id.btnFb); twitter = (Button)getActivity().findViewById(R.id.btnTwitter); mail = (Button)getActivity().findViewById(R.id.btnMail); System.out.println("K17"); new LongOperation().execute(); return view; } private class LongOperation extends AsyncTask<Void, Void, Void> { protected void onPreExecute() { } @Override protected Void doInBackground(Void... params) { // TODO Auto-generated method stub return null; } @Override protected void onPostExecute(Void result) { try{ fb.setOnClickListener(new OnClickListener() { public void onClick(View vb) { try{ System.out.println("7"); Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/10000003242252")); startActivity(intent); }catch(Exception e){ startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://m.facebook.com/facebook"))); } } }); twitter.setOnClickListener(new OnClickListener() { public void onClick(View vc) { try { Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("twitter://user?screen_name=dhoom")); startActivity(intent); }catch (Exception e) { startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://mobile.twitter.com/#!/dhoom"))); } } }); blog.setOnClickListener(new OnClickListener() { public void onClick(View va) { System.out.println("7s"); try { System.out.println("5s"); String url = "http://google.com"; Intent i = new Intent(Intent.ACTION_VIEW); i.setData(Uri.parse(url)); startActivity(i); } catch(Exception e){ System.out.println("6s"); startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"))); } } }); mail.setOnClickListener(new OnClickListener() { public void onClick(View va) { try { Intent send = new Intent(Intent.ACTION_SENDTO); String uriText = "mailto:" + Uri.encode("[email protected]") + "?subject=" + Uri.encode("the subject") + "&body=" + Uri.encode("the body of the message"); Uri uri = Uri.parse(uriText); send.setData(uri); startActivity(Intent.createChooser(send, "Send mail...")); } catch(Exception e){ Toast.makeText(getActivity().getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show(); // this.progressDialog.dismiss(); } } }); dateimg.setOnClickListener(new OnClickListener() { public void onClick(View va) { if(snet==false) { soundstart(); snet=true; } } }); } catch(Exception e){ //Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show(); } } } public void soundstart() { // TODO Auto-generated method stub MediaPlayer mplayer =MediaPlayer.create(getActivity(),R.raw.contact_sound); mplayer.start(); } }
