Android Fragment 构造函数

Android Fragment 构造函数和java不太一样，可以模仿原生的写法，如下：

CharSequence mLabel;  
  
    /** 
     * Create a new instance of MyFragment that will be initialized 
     * with the given arguments. 
     */  
    static MyFragment newInstance(CharSequence label) {  
        MyFragment f = new MyFragment();  
        Bundle b = new Bundle();  
        b.putCharSequence("label", label);  
        f.setArguments(b);  
        return f;  
    } 

下面是一个Test示例：

 public class TestFragment extends Fragment   
    {  
        private String name;  
        private String passwd;  
      
        public static TestFragment newInstance(String name, string passwd) {  
            TestFragment newFragment = new TestFragment();  
            Bundle bundle = new Bundle();  
            bundle.putString("name", name);  
            bundle.putString("passwd", passwd);  
            newFragment.setArguments(bundle);  
            return newFragment;  
      
        }  
		
	public void onCreate(Bundle savedInstanceState) {  
		super.onCreate(savedInstanceState);  
  
		Bundle args = getArguments();  
		if (args != null) {  
			name = args.getString("name");  
		passwd = args.getstring("passwd");  
		}  
	}

        @Override  
        public View onCreateView(LayoutInflater inflater, ViewGroup container,  
                Bundle savedInstanceState) {  
            // TODO Auto-generated method stub  
            View view = inflater.inflate(R.layout.main, null);  
              
            return view;  
        }  
		
      
    } 

调用：

    Fragment testFragment=TestFragment.newInstance("name","passwd");
