Activity和Fragment之间解耦

看鸿洋博客：http://blog.csdn.net/lmj623565791/article/details/42628537，整理下一些关键点

public class ContentFragment extends Fragment

{

    private String mArgument;

    public static final String ARGUMENT = "argument";

    @Override

    public void onCreate(Bundle savedInstanceState)

    {

        super.onCreate(savedInstanceState);

        // mArgument = getActivity().getIntent().getStringExtra(ARGUMENT);

        Bundle bundle = getArguments();

        if (bundle != null)

            mArgument = bundle.getString(ARGUMENT);

    }

    /**

     * 传入需要的参数，设置给arguments

     * @param argument

     * @return

     */

    public static ContentFragment newInstance(String argument)

    {

        Bundle bundle = new Bundle();

        bundle.putString(ARGUMENT, argument);

        ContentFragment contentFragment = new ContentFragment();

        contentFragment.setArguments(bundle);

        return contentFragment;

    }

通过在activity里面调用newInstance来将activity的内容传递给fragment,实现activity和fragment之间的解耦。

项目中也可以通过eventbus来实现activity和fragment直接的消息互通。
