java - 如何将值从 NavigationDrawerFragment.java 传递到 MainActivity.java 然后传递到 AnotherFragment 页面

Question

在我的 NavigationDrawerFragment.java

我有这个代码

expListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
    @Override
    public boolean onChildClick(ExpandableListView parent, View v,
                                int groupPosition, int childPosition, long id) {
        String header = listDataHeader.get(groupPosition);
        Category child = listDataChild.get(header).get(childPosition);

        // child.name to get the name
        // child.id to get the id
        //Toast.makeText(getActivity(),"ChildNme: "+child.name+" ChildId: "+child.id, Toast.LENGTH_SHORT).show();

        selectItem(1);

        return false;
    }
});

点击子项后，我将 selectItem 设置为 1

selectItem(1) 将转到 MainActivity.java

public void onNavigationDrawerItemSelected(int position) {
        // update the main content by replacing fragments

        FragmentManager fragmentManager = getFragmentManager();

        // NEW STUFF
        if(position == 1){
            fragmentManager.beginTransaction()
                    .replace(R.id.container, CategoryFragment.newInstance())
                    .commit();
        }

}

我的问题是如何将 child.name 和 child.id 从 NavigationDrawerFragment.java 传递到 MainActivity.java 然后传递到 CategoryFragment？

或任何其他将 child.name 和 child.id 传递给 CategoryFragment 的解决方案。

Answer 1

更新您的 selectitem() 和 onNavigationDrawerItemSelected 方法以接受另外两个参数，即 child.id 和 child.name

private void selectItem(int position,String id,String name) {
    mCurrentSelectedPosition = position;
    if (mDrawerListView != null) {
        mDrawerListView.setItemChecked(position, true);
    }
    if (mDrawerLayout != null) {
        mDrawerLayout.closeDrawer(mFragmentContainerView);
    }
    if (mCallbacks != null) {
        mCallbacks.onNavigationDrawerItemSelected(position,id,name);
    }
}

在 selectItem() 方法中传递 child.id 和 child.name，以便依次调用 MainActivity 中实现的 onNavigationDrawerItemSelected() 方法.

现在在 MainActivity 中，使用 Bundle 将值传递给 fragment 这里

fragmentManager.beginTransaction()
                .replace(R.id.container, CategoryFragment.newInstance(id,name))
                .commit();

您还需要更新到CategoryFragment.newInstance(String,String)以接受参数

将代码更新为“edittext”中的“setText”

在您的“CategoryFragment”“newInstance”方法中，将数据传递到 bundle 中，如下所示

CategoryFragment categoryfragment = new CategoryFragment()
Bundle bundle = new Bundle() 
bundle.putStringExtra("id",id)
bundle.putStringExtra("name",name)
categoryfragment.setArguements(bundle)

return categoryfragment

现在在 Categoryfragment 的 onCreateView 中获取如下数据

if(getArguments().getExtras != null) {
    String catid = getArguments.getStringExtra("id");
    String catname = getArguments.getStringExtra("name");

    yourEditText.setText(catname);
}

希望你明白我的意思
