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");
