Activity和Fragment之间相互传值和调用方法

1。Activity—>Fragment

用Bundle传值，

...        BlankFragment fragment = new BlankFragment();        Bundle args = new Bundle();        args.putString(ARG_PARAM1, param1);        args.putString(ARG_PARAM2, param2);        fragment.setArguments(args);...

Fragment onCreate中接受值

...        super.onCreate(savedInstanceState);        if (getArguments() != null) {            mParam1 = getArguments().getString(ARG_PARAM1);            mParam2 = getArguments().getString(ARG_PARAM2);        } ...

2。Fragment—>Activity

在Fragment中定义接口

...  public  interface Fragment2AtyListener{       void onFragment2Aty(Object object);    }    ...

让Activity实现Fragment2AtyListener接口

在Fragment中

...    /**     * 当Fragment被加载到activity的时候会被回调     *     * 判断宿主Activity是否实现了接口MyListener方法1     * @param context     */    @Override    public void onAttach(Context context) {        super.onAttach(context);        if(context instanceof Fragment2AtyListener)        {            mFragment2AtyListener = (Fragment2AtyListener)context;        }        else{            throw new IllegalArgumentException("Activity must implements Fragment2AtyListener");        }    }    /**     *判断宿主Activity是否实现了接口MyListener方法2     *//*    @Override    public void onAttach(Context context) {        super.onAttach(context);        try {            mFragment2AtyListener = (Fragment2AtyListener) context;        }catch (ClassCastException e) {            throw new ClassCastException(getActivity().getClass().getName()                    +"Activity must implements Fragment2AtyListener");        }    }*/ /**操作传值 通过接口回调*/ mFragment2AtyListener.onFragment2Aty("数据来自Fragment"); ...
