这是我的代码。适配器类。
package com.talagbe.schymn;
import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
public class HymnsAdapter extends ArrayAdapter<Hymns> {
ArrayList<Hymns> hymnarray;
Context context;
LayoutInflater inflater;
int Resource;
public HymnsAdapter(Context context, int resource, ArrayList<Hymns> objects) {
super(context, resource, objects);
// TODO Auto-generated constructor stub
hymnarray=objects;
Resource= resource;
this.context=context;
inflater= (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder holder;
if(convertView==null){
convertView= inflater.inflate(Resource,null);
holder= new ViewHolder();
holder.hymntitle= (TextView) convertView.findViewById(R.id.Hymn_title);
// holder.hymntext= (TextView) convertView.findViewById(R.id.Channel_name);
convertView.setTag(holder);
}else{
holder=(ViewHolder)convertView.getTag();
}
holder.hymntitle.setText(hymnarray.get(position).getTitle());
//holder.hymntext.setText(hymnarray.get(position).getText());
return convertView;
}
static class ViewHolder{
public TextView hymntitle;
public TextView hymntext;
}
}
这是另一个尝试实现过滤器的类。我有一个edittext，我在textChangeListener上实现，在日志中记录我键入的任何输入，但不显示列表视图。谢谢
#1 楼
您可以在适配器上使用Filterable接口，请看以下示例：public class SearchableAdapter extends BaseAdapter implements Filterable {
private List<String>originalData = null;
private List<String>filteredData = null;
private LayoutInflater mInflater;
private ItemFilter mFilter = new ItemFilter();
public SearchableAdapter(Context context, List<String> data) {
this.filteredData = data ;
this.originalData = data ;
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return filteredData.size();
}
public Object getItem(int position) {
return filteredData.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
// A ViewHolder keeps references to children views to avoid unnecessary calls
// to findViewById() on each row.
ViewHolder holder;
// When convertView is not null, we can reuse it directly, there is no need
// to reinflate it. We only inflate a new View when the convertView supplied
// by ListView is null.
if (convertView == null) {
convertView = mInflater.inflate(R.layout.list_item, null);
// Creates a ViewHolder and store references to the two children views
// we want to bind data to.
holder = new ViewHolder();
holder.text = (TextView) convertView.findViewById(R.id.list_view);
// Bind the data efficiently with the holder.
convertView.setTag(holder);
} else {
// Get the ViewHolder back to get fast access to the TextView
// and the ImageView.
holder = (ViewHolder) convertView.getTag();
}
// If weren't re-ordering this you could rely on what you set last time
holder.text.setText(filteredData.get(position));
return convertView;
}
static class ViewHolder {
TextView text;
}
public Filter getFilter() {
return mFilter;
}
private class ItemFilter extends Filter {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
final List<String> list = originalData;
int count = list.size();
final ArrayList<String> nlist = new ArrayList<String>(count);
String filterableString ;
for (int i = 0; i < count; i++) {
filterableString = list.get(i);
if (filterableString.toLowerCase().contains(filterString)) {
nlist.add(filterableString);
}
}
results.values = nlist;
results.count = nlist.size();
return results;
}
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
filteredData = (ArrayList<String>) results.values;
notifyDataSetChanged();
}
}
}
在Activity或Fragment中实例化适配器的位置：
editTxt.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
System.out.println("Text ["+s+"]");
mSearchableAdapter.getFilter().filter(s.toString());
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
@Override
public void afterTextChanged(Editable s) {
}
});
这里是原始来源的链接和另一个示例
#2 楼
希望对其他人有帮助。// put below code (method) in Adapter class
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
myList.clear();
if (charText.length() == 0) {
myList.addAll(arraylist);
}
else
{
for (MyBean wp : arraylist) {
if (wp.getName().toLowerCase(Locale.getDefault()).contains(charText)) {
myList.add(wp);
}
}
}
notifyDataSetChanged();
}
在适配器类中声明以下代码
private ArrayList<MyBean> myList; // for loading main list
private ArrayList<MyBean> arraylist=null; // for loading filter data
适配器构造函数中的以下代码
this.arraylist = new ArrayList<MyBean>();
this.arraylist.addAll(myList);
以及活动类中的以下代码
>
final EditText searchET = (EditText)findViewById(R.id.search_et);
// Capture Text in EditText
searchET.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
String text = searchET.getText().toString().toLowerCase(Locale.getDefault());
adapter.filter(text);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
});

private List<ItemsModel> itemsModelsl;
private List<ItemsModel> itemsModelListFiltered;
private Context context;

#5 楼
如果要在kotlin中使用自定义模型类实现过滤，则可以实现以下代码。步骤1：
在
SearchView文件中添加xml，然后在activity或fragment中实现SearchView.OnQueryTextListener class SearchActivity : AppCompatActivity(),SearchView.OnQueryTextListener {
lateinit var sectionModelArrayList: ArrayList<CategorySectionModel>
lateinit var filteredArrayList: ArrayList<CategorySectionModel>
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_category_updated)
searchView.setOnQueryTextListener(this)
}
//Called this method with you own data to populate the recycler view.
private fun parseJson() {
rv_category_list.layoutManager = LinearLayoutManager(this, RecyclerView.VERTICAL, false)
adapter = CategoryLabelAdapter(sectionModelArrayList, this)
rv_category_list.adapter = adapter
}
override fun onQueryTextSubmit(query: String?): Boolean {
return false
}
override fun onQueryTextChange(newText: String?): Boolean {
adapter.filter!!.filter(newText.toString())
return false
}
我的模型类
CategorySectionModel看起来像class CategorySectionModel(val categoryLabel: String, val categoryItemList: ArrayList<CategoryItem>)
现在我们有了要在适配器类上工作，则需要实现
Filterable接口并重写getFilter()方法，如下所示class CategoryLabelAdapter(internal var data: ArrayList<CategorySectionModel>?, internal var activity: Context) : RecyclerView.Adapter<CategoryLabelAdapter.ViewHolder>(), Filterable {
val originalList = data
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val v = LayoutInflater.from(parent.context).inflate(R.layout.item_category_name, parent, false)
return ViewHolder(v)
}
override fun getItemCount(): Int {
return data!!.size
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
data?.get(position)?.let { holder.bindItem(it) }
}
class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
@SuppressLint("SetTextI18n")
fun bindItem(data: CategorySectionModel) {
itemView.tv_category_name.text = data.categoryLabel
}
}
override fun getFilter(): Filter? {
return object : Filter() {
override fun performFiltering(constraint: CharSequence): FilterResults {
val results = FilterResults()
if (constraint.isEmpty()) {
//no filter implemented we return full list
results.values = data
results.count = data!!.size
} else {
//Here we perform filtering operation
val list: ArrayList<CategorySectionModel> = ArrayList()
for (p in data!!) {
if (p.categoryLabel.toUpperCase().startsWith(constraint.toString().toUpperCase())) list.add(p)
}
results.values = list
results.count = list.size
}
return results
}
override fun publishResults(constraint: CharSequence, results: FilterResults) {
// Now we have to inform the adapter about the new list filtered
if (results.count == 0 || constraint == "") {
data = originalList
notifyDataSetChanged()
} else {
data = results.values as ArrayList<CategorySectionModel>?
notifyDataSetChanged()
}
}
}
}
}
#6 楼
首先，您在xml文件中创建EditText并分配一个ID，例如con_pag_etPesquisa。之后，我们将创建两个列表，其中一个是列表视图，另一个将接收相同的内容，但将保留为备份。在将对象移到列表之前，首先对其进行初始化：
//Declaring
public EditText etPesquisa;
public ContasPagarAdapter adapterNormal;
public List<ContasPagar> lstBkp;
public List<ContasPagar> lstCp;
//Within the onCreate method, type the following:
etPesquisa = (EditText) findViewById(R.id.con_pag_etPesquisa);
etPesquisa.addTextChangedListener(new TextWatcher(){
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3){
filter(String.valueOf(cs));
}
@Override
public void beforeTextChanged(CharSequence cs, int arg1, int arg2, int arg3){
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable e){
}
});
//Before moving objects to lists first initializes them as below:
lstCp = new ArrayList<ContasPagar>();
lstBkp = new ArrayList<ContasPagar>();
//When you add objects to the main list, repeat the procedure also for bkp list, as follows:
lstCp.add(cp);
lstBkp.add(cp);
//Now initializes the adapter and let the listener, as follows:
adapterNormal = new ContasPagarAdapter(ContasPagarActivity.this, lstCp);
lvContasPagar.setAdapter(adapterNormal);
lvContasPagar.setOnItemClickListener(verificaClickItemContasPagar(lstCp));
//Now create the methods inside actito filter the text entered by the user, as follows:
public void filter(String charText){
charText = charText.toLowerCase();
lstCp.clear();
if (charText.length() == 0){
lstCp.addAll(lstBkp);
appendAddItem(lstBkp);
}
else {
for (int i = 0; i < lstBkp.size(); i++){
if((lstBkp.get(i).getNome_lancamento() + " - " + String.valueOf(lstBkp.get(i).getCodigo())).toLowerCase().contains(charText)){
lstCp.add(lstBkp.get(i));
}
}
appendAddItem(lstCp);
}
}
private void appendAddItem(final List<ContasPagar> novaLista){
runOnUiThread(new Runnable(){
@Override
public void run(){
adapterNormal.notifyDataSetChanged();
}
});
}
#7 楼
您可以通过两种方式在列表视图中实现搜索过滤器。 1.使用searchview 2.使用edittext。如果要使用searchview，请阅读此处：searchview过滤器。
如果要使用edittext，请阅读以下内容。
我从以下列表中引用了内容：listview搜索过滤器android
代码片段以使用edittext进行过滤。 />
public class MovieNames {
private String movieName;
public MovieNames(String movieName) {
this.movieName = movieName;
}
public String getMovieName() {
return this.movieName;
}
}
创建listview_item.xml文件：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp">
<TextView
android:id="@+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
制作ListViewAdapter.java类：
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.Locale;
public class ListViewAdapter extends BaseAdapter {
// Declare Variables
Context mContext;
LayoutInflater inflater;
private ArrayList<MovieNames> arraylist;
public ListViewAdapter(Context context, ArrayList<MovieNames> arraylist) {
mContext = context;
inflater = LayoutInflater.from(mContext);
this.arraylist = arraylist;
}
public class ViewHolder {
TextView name;
}
@Override
public int getCount() {
return arraylist.size();
}
@Override
public MovieNames getItem(int position) {
return arraylist.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
public View getView(final int position, View view, ViewGroup parent) {
final ViewHolder holder;
if (view == null) {
holder = new ViewHolder();
view = inflater.inflate(R.layout.listview_item, null);
// Locate the TextViews in listview_item.xml
holder.name = (TextView) view.findViewById(R.id.name);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
// Set the results into TextViews
holder.name.setText(arraylist.get(position).getMovieName());
return view;
}
}
准备activity_main.xml文件：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.parsaniahardik.searchedit.MainActivity"
android:orientation="vertical">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/editText"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:hint="enter query"
android:singleLine="true">
<requestFocus/>
</EditText>
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/listView"
android:divider="#694fea"
android:dividerHeight="1dp" />
</LinearLayout>
最后制作MainActivity.java类：
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.util.Log;
import android.view.View;
import android.widget.AdapterView;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.SearchView;
import android.widget.Toast;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
private EditText etsearch;
private ListView list;
private ListViewAdapter adapter;
private String[] moviewList;
public static ArrayList<MovieNames> movieNamesArrayList;
public static ArrayList<MovieNames> array_sort;
int textlength = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Generate sample data
moviewList = new String[]{"Xmen", "Titanic", "Captain America",
"Iron man", "Rocky", "Transporter", "Lord of the rings", "The jungle book",
"Tarzan","Cars","Shreck"};
list = (ListView) findViewById(R.id.listView);
movieNamesArrayList = new ArrayList<>();
array_sort = new ArrayList<>();
for (int i = 0; i < moviewList.length; i++) {
MovieNames movieNames = new MovieNames(moviewList[i]);
// Binds all strings into an array
movieNamesArrayList.add(movieNames);
array_sort.add(movieNames);
}
adapter = new ListViewAdapter(this,movieNamesArrayList);
list.setAdapter(adapter);
etsearch = (EditText) findViewById(R.id.editText);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(MainActivity.this, array_sort.get(position).getMovieName(), Toast.LENGTH_SHORT).show();
}
});
etsearch.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
textlength = etsearch.getText().length();
array_sort.clear();
for (int i = 0; i < movieNamesArrayList.size(); i++) {
if (textlength <= movieNamesArrayList.get(i).getMovieName().length()) {
Log.d("ertyyy",movieNamesArrayList.get(i).getMovieName().toLowerCase().trim());
if (movieNamesArrayList.get(i).getMovieName().toLowerCase().trim().contains(
etsearch.getText().toString().toLowerCase().trim())) {
array_sort.add(movieNamesArrayList.get(i));
}
}
}
adapter = new ListViewAdapter(MainActivity.this, array_sort);
list.setAdapter(adapter);
}
});
}
}

我注意到的一件事是，无论何时编辑列表（例如添加项目）并对其进行过滤，然后在@Override getView方法内部，都不应使用filteredData.get(position)，因为它会引发IndexOutOfBounds异常。 > 相反，对我有用的是使用属于
getItem(position)类的ArrayAdapter方法。#10 楼
只是更新。如果勾选的答案对您来说很好，但是当搜索文本为空时则不显示任何内容。解决方法如下：
private class ItemFilter extends Filter {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
if(constraint.length() == 0)
{
results.count = originalData.size();
results.values = originalData;
}else {
final List<String> list = originalData;
int count = list.size();
final ArrayList<String> nlist = new ArrayList<String>(count);
String filterableString ;
for (int i = 0; i < count; i++) {
filterableString = list.get(i);
if (filterableString.toLowerCase().contains(filterString)) {
nlist.add(filterableString);
}
}
results.values = nlist;
results.count = nlist.size();
}
return results;
}
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
filteredData = (ArrayList<String>) results.values;
notifyDataSetChanged();
}
}
