android fragment向action bar添加菜单处理，隐藏等

 可以给不同的fragment添加不同的actionbar

一：覆盖onCreateOptionsMenu方法增加菜单文件
       

[java] view plain copy

1. @Override  
2.     public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {  
3.         // TODO Auto-generated method stub  
4.         inflater.inflate(R.menu.main, menu);      
5.         super.onCreateOptionsMenu(menu, inflater);        
6.     }  

 

二：必须要在onCreate里边加上setHasOptionsMenu(true)

[java] view plain copy

1. @Override  
2.     public void onCreate(Bundle savedInstanceState) {  
3.         // TODO Auto-generated method stub  
4.         super.onCreate(savedInstanceState);  
5.         setHasOptionsMenu(true);//添加菜单不调用该方法是没有用的  
6.     }  

三：覆盖onOptionsItemSelected方法添加菜单影响事件

  

[java] view plain copy

1. @Override  
2.     public boolean onOptionsItemSelected(MenuItem item) {  
3.         // TODO Auto-generated method stub  
4.          switch (item.getItemId()) {    
5.             case R.id.xx:    
6.                 Toast.makeText(getActivity(), "xx", Toast.LENGTH_SHORT).show();    
7.                 return true;    
8.             case R.id.bb:    
9.                 Toast.makeText(getActivity(), "bb", Toast.LENGTH_SHORT).show();    
10.                 return true;    
11.             case R.id.cc:    
12.                 Toast.makeText(getActivity(), "cc", Toast.LENGTH_SHORT).show();    
13.                 return true;    
14.             case android.R.id.home:    
15.                 Toast.makeText(getActivity(), "home", Toast.LENGTH_SHORT).show();    
16.                 getActivity().finish();    
17.                 return true;  
18.             default:    
19.                 return super.onOptionsItemSelected(item);    
20.             }    
21.     }

二：隐藏Navigation

getActivity().getActionBar().setDisplayHomeAsUpEnabled(false);
        getActivity().getActionBar().setNavigationMode(ActionBar.DISPLAY_HOME_AS_UP);
