我想从屏幕上删除“无限加载微调器”。我发布了一个从android studio生成的默认片段列表代码：
var postcodes = ["E1", "E2", "E3", "E4", "E5", "E6", "E7", "E8", "E9", "E10", "E11", "E12", "E13", "E14", "E15", "E16", "E17", "E18"];
$('#searchForm').submit(function(e){
var postcode = $('#searchForm input').val().toUpperCase();
var postcodeAreaDeliverable = false;
$.each( postcodes, function( index, value ) {
if (postcode.match("^" + value)) {
postcodeAreaDeliverable = true;
}
});
if (postcodeAreaDeliverable) {
$('#result').html('Yes, we deliver!');
} else {
$('#result').html('Sorry, we dont deliver!');
}
return false;
});
}
我的适配器：
public class DummyContent {
/**
* An array of sample (dummy) items.
*/
public static final List<DummyItem> ITEMS = new ArrayList<DummyItem>();
/**
* A map of sample (dummy) items, by ID.
*/
public static final Map<String, DummyItem> ITEM_MAP = new HashMap<String, DummyItem>();
private static final int COUNT = 25;
static {
// Add some sample items.
for (int i = 1; i <= COUNT; i++) {
addItem(createDummyItem(i));
}
}
private static void addItem(DummyItem item) {
ITEMS.add(item);
ITEM_MAP.put(item.id, item);
}
private static DummyItem createDummyItem(int position) {
return new DummyItem(String.valueOf(position), "Item " + position, makeDetails(position));
}
private static String makeDetails(int position) {
StringBuilder builder = new StringBuilder();
builder.append("Details about Item: ").append(position);
for (int i = 0; i < position; i++) {
builder.append("\nMore details information here.");
}
return builder.toString();
}
/**
* A dummy item representing a piece of content.
*/
public static class DummyItem {
public final String id;
public final String content;
public final String details;
public DummyItem(String id, String content, String details) {
this.id = id;
this.content = content;
this.details = details;
}
@Override
public String toString() {
return content;
}
}
}
public class MyProvaRecyclerViewAdapter extends RecyclerView.Adapter<MyProvaRecyclerViewAdapter.ViewHolder> {
private final List<DummyItem> mValues;
private final OnListFragmentInteractionListener mListener;
public MyProvaRecyclerViewAdapter(List<DummyItem> items, OnListFragmentInteractionListener listener) {
mValues = items;
mListener = listener;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.fragment_prova, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(final ViewHolder holder, int position) {
holder.mItem = mValues.get(position);
holder.mIdView.setText(mValues.get(position).id);
holder.mContentView.setText(mValues.get(position).content);
holder.mView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (null != mListener) {
// Notify the active callbacks interface (the activity, if the
// fragment is attached to one) that an item has been selected.
mListener.onListFragmentInteraction(holder.mItem);
}
}
});
}
@Override
public int getItemCount() {
return mValues.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
public final View mView;
public final TextView mIdView;
public final TextView mContentView;
public DummyItem mItem;
public ViewHolder(View view) {
super(view);
mView = view;
mIdView = (TextView) view.findViewById(R.id.id);
mContentView = (TextView) view.findViewById(R.id.content);
}
@Override
public String toString() {
return super.toString() + " '" + mContentView.getText() + "'";
}
}
}
我无法理解为什么当我开始时：
public class ProvaFragment extends Fragment {
// TODO: Customize parameter argument names
private static final String ARG_COLUMN_COUNT = "column-count";
// TODO: Customize parameters
private int mColumnCount = 1;
private OnListFragmentInteractionListener mListener;
/**
* Mandatory empty constructor for the fragment manager to instantiate the
* fragment (e.g. upon screen orientation changes).
*/
public ProvaFragment() {
}
// TODO: Customize parameter initialization
@SuppressWarnings("unused")
public static ProvaFragment newInstance(int columnCount) {
ProvaFragment fragment = new ProvaFragment();
Bundle args = new Bundle();
args.putInt(ARG_COLUMN_COUNT, columnCount);
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
mColumnCount = getArguments().getInt(ARG_COLUMN_COUNT);
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_prova_list, container, false);
// Set the adapter
if (view instanceof RecyclerView) {
Context context = view.getContext();
RecyclerView recyclerView = (RecyclerView) view;
if (mColumnCount <= 1) {
recyclerView.setLayoutManager(new LinearLayoutManager(context));
} else {
recyclerView.setLayoutManager(new GridLayoutManager(context, mColumnCount));
}
recyclerView.setAdapter(new MyProvaRecyclerViewAdapter(DummyContent.ITEMS, mListener));
}
return view;
}
@Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof OnListFragmentInteractionListener) {
mListener = (OnListFragmentInteractionListener) context;
} else {
throw new RuntimeException(context.toString()
+ " must implement OnListFragmentInteractionListener");
}
}
@Override
public void onDetach() {
super.onDetach();
mListener = null;
}
/**

*/
public interface OnListFragmentInteractionListener {
// TODO: Update argument type and name
void onListFragmentInteraction(DummyItem item);
}
生成一个默认列表，在片段中心有一个无限加载微调器，但它从未声明，我该如何删除它？
片段提示的XML代码：
ProvaFragment pf = new ProvaFragment();
FragmentTransaction lfrg = getSupportFragmentManager().beginTransaction().add(R.id.fragment, pf);
lfrg.commitNow();
和fragment_prova列表：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="@+id/id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="@dimen/text_margin"
android:textAppearance="?attr/textAppearanceListItem" />
<TextView
android:id="@+id/content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="@dimen/text_margin"
android:textAppearance="?attr/textAppearanceListItem" />
