Question

我想将表单分成2个选项卡，第二个选项卡包含确认底部应检查所需字段是否为填写并继续将其提交给服务器。

部分必填字段位于片段1（标签1）和我的按钮中 onclick函数位于片段2（tab2）上。

如何将EditText视图组件从片段1 xml传递给片段2 java类。

或者我应该将所有功能都放在主要活动中吗？

主要活动

   $(submitInput).after("<div className=\"alert alert-danger\" role=\"alert\">Wrong Phone Format</div>");

Answer 1

在你的主片段（一个持有视图分页器，标签布局）中保留两个片段的引用（你只需要fisrt，但万一以后你可能还需要第二个）。像这样：

在您的片段2中，您想要引用它并检查一些结果，请执行以下操作：当您在持有mainfragment的ur活动中执行事务时，请确保已为主片段设置了标记。这样你就可以使用标签来引用主片段。

private SparseArray<Fragment> registeredFragments = new SparseArray<Fragment>();
@Override
    public Object instantiateItem(ViewGroup container, int position) {
        Log.d("dj", "intializing items FragPageAdapter");
        Fragment fragment = (Fragment) super.instantiateItem(container, position);
        registeredFragments.put(position, fragment);
        return fragment;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        Log.d("dj", "destroyed items FragPageAdapter");
        registeredFragments.remove(position);
        super.destroyItem(container, position, object);
    }

    public Fragment getRegisteredFragment(int fragmentPosition) {

    return registeredFragments.get(fragmentPosition);
    }

在第二个片段中获取第一个片段的引用，如下所示：

mainFragment= (MainFragment) getActivity().getSupportFragmentManager().
            findFragmentByTag(ActivityHoldingMainFragment.TAG_FOR_MAIN_FRAG);

// findFragmentByPosition（0）将持有第一个片段;

在第一个片段中创建一个获取所有数据的方法;像这样：

public Fragment findFragmentByPosition(int fragmentPosition) {

    return mainFragment.getRegisteredFragment(fragmentPosition);
}
FirstFragment firstFrag = (FirstFragment ) findFragmentByPosition(0);
ArrayList<String> formOneData = firstFrag.getFormOneData();

FragmentTabHost将View组件从Fragment传递到另一个Fragment
