Question

我已使用this教程实现了可交换的标签视图。

我想将一个整数值从Fragment传递给FragmentActivity。怎么做？

我的fragment.java：

public PastaFragment(FragmentManager fm, int hot_number) {
        super();

        this.hot_number = hot_number;
    }

内部片段onCreate：

mCartList = ShoppingCartHelper.getCartList();

        // Make sure to clear the selections
        for (int i = 0; i < mCartList.size(); i++) {
            mCartList.get(i).selected = false;

            hot_number = mCartList.size();
            System.out.println("hot_number11 = " + hot_number);

        }

        Fragment Pasfragment = new PastaFragment(getFragmentManager(), hot_number);
        Bundle bundle = new Bundle();
        bundle.putLong("hot_number", hot_number);

        Pasfragment.setArguments(bundle);

内部activityfragment.java：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_menu);

        hot_number = getIntent().getIntExtra("hot_number", hot_number);

内部TabsPagerAdapter.java：

@Override
    public Fragment getItem(int index) {

        switch (index) {
        case 0:

            FragmentManager getFragmentManager = null;
            return new PastaFragment(getFragmentManager, index);
        }

        return null;
    }

尝试这种方式：

Intent intent = new Intent(getActivity(), YourFragmentActivity.class);
intent.putExtra("YourInteger", 1);
getActivity().startActivity(intent);

如何在Android中将整数值从Fragment传递到FragmentActivity？
