Wie man eine Aktivität in ein Fragment umwandelt, das im Registerkartenlayout verwendet wird

Question

Hier ist eine Aktivität, die ich in ein Fragment konvertieren wollte, also könnte ich es in einem Sliding-Tab-Layout als Fragment verwenden.

package com.example.hpuser.speechtotext; 
public class MainActivity extends AppCompatActivity { 
TextView resultTEXT; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 

setContentView(R.layout.activity_main); 
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
setSupportActionBar(toolbar); 
}); 
resultTEXT= (TextView)findViewById(R.id.TVresult); 
} 

public void onButtonClick(View v) { 
if (v.getId() == R.id.imageButton) { 
promptSpeechInput();  
} 
} 

public void promptSpeechInput() { 
Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,   
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); 
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault()); 
i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say something!"); 

try { 
startActivityForResult(i, 100); 
} 
catch(ActivityNotFoundException a) 
{ 
Toast.makeText(MainActivity.this, "Sorry! your device does not support  
speech Language!", Toast.LENGTH_LONG).show(); 
} 
} 

public void onActivityResult(int request_code, int result_code, Intent i) { 
super.onActivityResult(request_code, result_code, i); 

switch(request_code) 
{ 
case 100: if(result_code == RESULT_OK && i != null) 
{ 
ArrayList<String> result =  
i.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS); 
     resultTEXT.setText(result.get(0)); 

      } 
       break; 
     } 


} 

Hier ist das eigentliche Fragment der Aktivität, die ich codieren. Die App stürzt aber ab, jede Hilfe?

package com.example.vez.design3; 
public class HomeFragment extends Fragment { 
TextView resultTEXT; 

private LinearLayout llLayout; 
private FragmentActivity faActivity; 
public HomeFragment() { 
    // Required empty public constructor 

} 


@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
Bundle savedInstanceState) { 
// Inflate the layout for this fragment 
faActivity = (FragmentActivity) super.getActivity(); 
llLayout = (LinearLayout) inflater.inflate(R.layout.fragment_home, 
container, false); 

resultTEXT = (TextView) llLayout.findViewById(R.id.TVresult); 

return llLayout; 

} 


public void promptSpeechInput() { 
Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); 
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault()); 
i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say something!"); 

try { 
startActivityForResult(i, 100); 
} 
catch(ActivityNotFoundException a) 
{ 
Toast.makeText(super.getActivity(), "Sorry! your device does not 
support speech Language!", Toast.LENGTH_LONG).show(); 
} 
} 

public void onActivityResult(int request_code, int result_code, Intent i) { 
super.onActivityResult(request_code, result_code, i); 

switch(request_code) 
{ 
case 100: if(result_code == 1 && i != null) 
{ 
ArrayList<String> result =  
i.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS); 
resultTEXT.setText(result.get(0)); 

} 
break; 
} 


} 



}

Statt dessen

private LinearLayout llLayout; und llLayout = (LinearLayout)inflater.inflate(R.layout.fragment_home,container, false);

Probieren Sie diese

View view=inflater.inflate(R.layout.fragment_home, null, false); 
    resultTEXT = (TextView) view.findViewById(R.id.TVresult); 
    return view;
