Android 创建fragment时向fragment中传数据

有两个fragment分别为FragementA和FragmentB,现在要从FragementA跳转到FragmentB。同时要向FragmentB中传入数据,首先要在FragmentB中创建静态的方法,如下:

public static FragmentB getInstance(ObjectA object) {
		FragmentB fragment = new FragmentB();
		Bundle bundle = new Bundle();
		bundle.putSerializable(Constants.BundleKey.Object, result);
		fragment.setArguments(bundle);
		return fragment;
	}

 


在FragementA中跳转的时候:

FragmentB fragment = FragmentB .getInstance(result);
addFragmentToStack(fragment, true, true);

其中addFragmentToStack代码:

protected void addFragmentToStack(final Fragment fragment,
			final boolean isAddToBack, boolean hasAnimation) {
		FragmentTransaction ft = getFragmentManager().beginTransaction();
		try {
			if (hasAnimation) {
				ft.setCustomAnimations(R.anim.slide_right_in, R.anim.slide_left_out,
						R.anim.slide_left_in, R.anim.slide_right_out);
			}
		} catch (ArrayIndexOutOfBoundsException e) {
			throw new ArrayIndexOutOfBoundsException(
					"动画数组下标越界");
		}
		ft.add(R.id.fragment_container, fragment);
		if (isAddToBack) {
			ft.addToBackStack(null);
		}
		ft.commit();
	}
这样就实现了fragment跳转的时候传递数据,在FragmentB中要把传递的数据取出,否则传数据就没有意义了,代码:

ObjectA object = (ObjectA) getArguments().getSerializable(Constants.BundleKey.Object);
其中ObjectA这个类要实现Serializable方法,否则也是不能传递的,切记切记!!
