这是我的CategoryFragment：
public class CategoryFragment extends Fragment implements CategoriesItemsAdapter.CategoriesDelegate {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.fragment_budget,container,false);
mSavedInstanceState= savedInstanceState;
return mView;
}
private void setGridViewAdapter(ArrayList<String> texts, ArrayList<Integer> icons){
mCategories = (GridView) mView.findViewById(R.id.categories);
CategoriesItemsAdapter adapter = new CategoriesItemsAdapter(getActivity(),texts,icons);
adapter.CategoriesDelegate = this;
mCategories.setAdapter(adapter);
}
@Override
public void categoriesDelegate() {
MainActivity activity = (MainActivity) getActivity();
FragmentManager manager = activity.getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
if (mSavedInstanceState == null) {
transaction.replace(R.id.categories_frame, new CategoriesFragment());
}
transaction.addToBackStack(null);
transaction.commit();
}
}
这是我的CategoriesItemsAdapter：
public class CategoriesItemsAdapter extends BaseAdapter implements View.OnClickListener {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = mInflater.inflate(R.layout.item_categories, parent, false);
}
ImageView icon = (ImageView) convertView.findViewById(R.id.icon);
TextView text = (TextView) convertView.findViewById(R.id.category_name);
text.setText(mTexts.get(position));
icon.setImageResource(mIcons.get(position));
icon.setOnClickListener(this);
return convertView;
}
@Override
public void onClick(View v) {
if (CategoriesDelegate != null) {
CategoriesDelegate.categoriesDelegate();
}
}
public interface CategoriesDelegate {
void categoriesDelegate();
}
}
我想在点击网格视图项时打开一个片段。我可以打开一个片段，但片段在错误的位置打开。片段始终在第一个项目中打开。我在该网格视图项中单击了哪个网格视图项，应该打开片段。我怎么能解决这个问题？
这是我的items_categories.xml：
