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。
