MainActivity.java：

public class MainActivity extends ActionBarActivity { 

    static final String EXTRA_MESSAGE = "com.example.test.MESSAGE"; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     if (savedInstanceState == null) { 
      getSupportFragmentManager().beginTransaction() 
        .add(R.id.container, new PlaceholderFragment()).commit(); 
     } 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu items for use in the action bar 
     MenuInflater inflater = getMenuInflater(); 
     inflater.inflate(R.menu.main_activity_actions, menu); 
     return super.onCreateOptionsMenu(menu); 
    } 

    @Override

     // automatically handle clicks on the Home/Up button, so long

     int id = item.getItemId(); 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 

    public void sendMessage(View view) { 
     Intent intent = new Intent(this, DisplayMessageActivity.class); 
     EditText editText = (EditText) findViewById(R.id.edit_message); 
     String message = editText.getText().toString(); 
     intent.putExtra(EXTRA_MESSAGE, message); 
     startActivity(intent); 
    } 

    /** 
    * A placeholder fragment containing a simple view. 
    */ 
    public static class PlaceholderFragment extends Fragment { 

     public PlaceholderFragment() { 
     } 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, 
       Bundle savedInstanceState) { 
      View rootView = inflater.inflate(R.layout.fragment_main, container, 
        false); 
      return rootView; 
     } 

    } 

}

嘗試用更換您的菜單功能：

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu items for use in the action bar 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.main_activity_actions, menu); 
    return true; 
} 

我認爲並不需要超通話和混亂的事情。
