I can't add search feature to my listview

I can't add search feature to my listview - java

I have an listview in my application and when I add search to my listview it dosen't work at all.
when I add those code to my project, getfilter doesn't resolve.
enter code here

}
my broblem is this code.
enter code here
MyActivity.this.adapter.getFilter().filter(arg0);
why getFilter() doesn't resolve?
Is it releted to my adaptor?
please help

why getFilter() doesn't resolve?
Because Filterable interface is not implemented in VehicleAdapter class.
To call adapter.getFilter().filter for Activity usng Adapter object need to implement Filterable interface in Adapter class and override getFilter.
See following example how to make Adapter Filterable:
Android Filter Custom ListView (BaseAdapter)

In custom adapter it would not work. this code for search will work in SimpleAdapter. For your adapter you have to write custom code for search.
Follow this link it would do as per your need (search filter in custom adapetr)

How can I open original activities by clicking a listview item after filtering listview?

My code is working fine when it comes to clicking items. But the problem arises when I try to open activities after filtering listview. It always opens activity 1.
Here is my source code.

How can I open different activities while clicking on listview items after I filter them.
This is the sample code I used. Although it doesn't provide the functionality to open original activities through intent ,just some forged up activity,so I'm trying to change that.

How to save a SparseBooleanArray using SharedPreferences? Or any other alternative?

I'd like to save SparseBooleanArray using either SharedPreferences, or anything else, that's more preferred.
I've tried using https://stackoverflow.com/a/16711258/2530836, but everytime the activity is created, bundle is re-initialized, and bundle.getParcelable() returns null. I'm sure there is a workaround for this, but I haven't arrived at it despite a few hours of brainstorming.
Also, if there isn't, could I use something like SharedPreferences?
Here's the code:
public class ContactActivity extends Activity implements AdapterView.OnItemClickListener {
List<String> name1 = new ArrayList<String>();
List<String> phno1 = new ArrayList<String>();
ArrayList<String> exceptions = new ArrayList<String>();
MyAdapter adapter;
Button select;
Bundle bundle = new Bundle();
Context contactActivityContext;
SharedPreferences prefs;
SharedPreferences.Editor editor;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contacts_layout);
getAllContacts(this.getContentResolver());
ListView list= (ListView) findViewById(R.id.lv);
adapter = new MyAdapter();
list.setAdapter(adapter);
list.setOnItemClickListener(this);
list.setItemsCanFocus(false);
list.setTextFilterEnabled(true);
prefs = PreferenceManager.getDefaultSharedPreferences(this);
select = (Button) findViewById(R.id.button1);
select.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
StringBuilder checkedcontacts = new StringBuilder();
for (int i = 0; i < name1.size(); i++)
{
if (adapter.isChecked(i)) {
checkedcontacts.append(name1.get(i).toString());
exceptions.add(name1.get(i).toString());
checkedcontacts.append(", ");
}
}
checkedcontacts.deleteCharAt(checkedcontacts.length() - 2);
checkedcontacts.append("selected");
editor = prefs.edit();
editor.putInt("Status_size", exceptions.size()); /* sKey is an array */
for(int i=0;i<exceptions.size();i++)
{
editor.remove("Status_" + i);
editor.putString("Status_" + i, exceptions.get(i));
}
editor.commit();
Toast.makeText(ContactActivity.this, checkedcontacts, Toast.LENGTH_LONG).show();
}

You can store it in SharedPreferances
The thing about sparsebooleanarrays is: it maps integers to boolean values, hence you can save it as a string, eliminate the braces,spaces and = signs, and all you have is an int value (for index value) and the corresponding boolean value, separated by a comma, now use the string accordingly. Hope it helps :)

Bundle is created by you in the class and it is not used by activity to store the value.
If You're using the bundle of application, still you can't get the instance once you killed the application.
For you're problem better go with shared preference but in shared preference you can't store objects.
If you want to use shared preference then there are 2 solutions.
Convert object to string and store in shared preference and retrieve back and reform the Object from String. (use Gson or Jackson or you're preferred way )
Use Complex Preferences third party one, Where you can store objects and retrieve directly.
If you're more interested using bundle only then Check this discussion on stackoverflow.

Set onItemClick to Custom adapter ListView

When I had problems trying to fix the position of my listView items to the desired intent when filtered, and got info I could override the problem using a custom adapter, I have done that but I do not know how to assign the clicks to each items, please check below code:
public class IndexPageActivity extends Activity {
ListView listView;
EditText editTextB;
#Override
protected void onCreate(Bundle savfedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.indexpage);
listView = (ListView) findViewById(R.id.pageList);
editTextB = (EditText) findViewById(R.id.searchB);
listView.setAdapter(new PagesAdapter(this));
listView.setOnItemClickListener((OnItemClickListener) this);
}
}
class SingleRow {
String pagedata;
SingleRow(String pagedata){
this.pagedata=pagedata;
}
}
class PagesAdapter extends BaseAdapter implements OnItemClickListener{
ArrayList<SingleRow> pagelist;
Context context;
PagesAdapter(Context c){
context=c;
pagelist = new ArrayList<SingleRow>();
Resources res = c.getResources();
String [] pagedatas = res.getStringArray(R.array.pages_data);
for (int i=0;i<463;i++){
pagelist.add(new SingleRow(pagedatas[i]));
}
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return pagelist.size();
}
#Override
public Object getItem(int i) {
// TODO Auto-generated method stub
return pagelist.get(i);
}
#Override
public long getItemId(int i) {
// TODO Auto-generated method stub
return i;
}
#Override
public View getView(int i, View view, ViewGroup viewG) {
// TODO Auto-generated method stub
LayoutInflater inflater=(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row=inflater.inflate(R.layout.single_row,viewG,false);
TextView pagetitle = (TextView) row.findViewById(R.id.textViewRow);
SingleRow temp=pagelist.get(i);
pagetitle.setText(temp.pagedata);
return row;
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int i, long arg3) {
// TODO Auto-generated method stub
}
}
I will appreciate any help given. Thank Yhu!
EDIT
Will this work?
if (index == 0) {
Intent i = new Intent(this, WebViewActivity.class);
i.putExtra("keyHTML", "file:///android_asset/page1.html");
startActivity(i);
} else if (index == 1) {
Intent i = new Intent(this, WebViewActivity.class);
i.putExtra("keyHTML", "file:///android_asset/page2.html");
startActivity(i);

Edited ALL
I just got what you need, I added a filter to your baseAdapter and then on text change within the editText You filter the listView and then you go to the activity needed.
here is the full code but you need to bare in mind that I have changed the following:
I changed the pageList to ArrayList instead of
There is a bug in filtering that when I erase what I wrote in the EditText it doesnt update the ListView, you need to figure out why.
I changed the returned value of the function getItem(int i) from Object to String
Within the onItemClick you have to search for the name instead of the position.
here is the code:
public class IndexPageActivity extends Activity implements OnItemClickListener{
ListView listView;
EditText editTextB;
PagesAdapter adapter1;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView) findViewById(R.id.pageList);
editTextB = (EditText) findViewById(R.id.searchB);
adapter1 = new PagesAdapter(this);
listView.setAdapter(adapter1);
adapter1.notifyDataSetChanged();
listView.setOnItemClickListener(this);
editTextB.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence cs, int arg1, int arg2,
int arg3) {
// When user changed the Text
IndexPageActivity.this.adapter1.getFilter().filter(cs.toString());
adapter1.notifyDataSetChanged();
}
#Override
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
#Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
});
}
#Override
public void onItemClick(AdapterView<?> arg0, View v, int position, long arg3) {
// TODO Auto-generated method stub
Intent i;
String name = adapter1.getItem(position);
Log.d("id", name);
if (name.equals("Item1"))
{
i = new Intent(this, anActivity.class);
startActivity(i);
}
else if (name.equals("Item2"))
{
i = new Intent(this, anActivity2.class);
startActivity(i);
}
}
}
class SingleRow {
String pagedata;
SingleRow(String pagedata){
this.pagedata=pagedata;
}
}
class PagesAdapter extends BaseAdapter implements Filterable{
ArrayList<String> pagelist;
List<String> arrayList;
Context context;
String [] pagedatas;
PagesAdapter(Context c){
context=c;
pagelist = new ArrayList<String>();
Resources res = c.getResources();
pagedatas = res.getStringArray(R.array.pages_data);
for (int i=0;i<463;i++){
pagelist.add(pagedatas[i]);
}
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return pagelist.size();
}
#Override
public String getItem(int i) {

String temp=pagelist.get(i);
pagetitle.setText(temp);
return row;
}
public class filter_here extends Filter{
#Override
protected FilterResults performFiltering(CharSequence constraint) {
// TODO Auto-generated method stub
FilterResults Result = new FilterResults();
// if constraint is empty return the original names
if(constraint.length() == 0 ){
Result.values = pagelist;
Result.count = pagelist.size();
return Result;
}
ArrayList<String> Filtered_Names = new ArrayList<String>();
String filterString = constraint.toString().toLowerCase();
String filterableString;
for(int i = 0; i<pagelist.size(); i++){
filterableString = pagelist.get(i);
if(filterableString.toLowerCase().contains(filterString)){
Filtered_Names.add(filterableString);

Two different ways for it:
1) If you want to use something like this at onCreate of your activity;
listView.setOnItemClickListener((OnItemClickListener) this);
You should implement OnItemClickListener to your activity:
IndexPageActivity extends Activity implements OnItemClickListener
and implement its onItemClick method at your activity. (also remove OnItemClickListener interface from your custom adapter)
2) You can simply use below without implementing OnItemClickListener to any class:
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// TODO: handle row clicks here
}
I suggest 2nd option. That is easier.
Edit: This not relevant to your problem but you should reuse your views/rows at listView. Change your getView method to:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view;
if (convertView == null) {
LayoutInflater inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.single_row, parent, false);
} else {
view = convertView;
}
TextView pagetitle = (TextView) view.findViewById(R.id.textViewRow);
SingleRow temp=pagelist.get(i);
pagetitle.setText(temp.pagedata);
return view;
}

Set your setOnItemClickListenerlike this:
#Override
protected void onCreate(Bundle savfedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.indexpage);
listView = (ListView) findViewById(R.id.pageList);
editTextB = (EditText) findViewById(R.id.searchB);
listView.setAdapter(new PagesAdapter(this));
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
//Your code here
//int position is the index of the list item you clicked
//use it to manipulate the item for each click
}
});
}

It was hard to find out what went wrong
You have this and CustomAdapter. You have button inside the activity_row2 inflated for your row items.
dataAdapter = new SimpleCursorAdapter(
this, R.layout.activity_row2,
projectsCursor,
from,
to,
0);
You have defined a CustomAdapter but never use it.
String[] from = new String[]{GinfyDbAdapter.CATEGORY_COLUMN_TITLE,GinfyDbAdapter.CATEGORY_COLUMN_CONTENT,GinfyDbAdapter.CATEGORY_COLUMN_COUNT};
// and an array of the fields we want to bind those fields to (in this case just text1)
int[] to = new int[]{R.id.text2,R.id.text1,R.id.count};
dataAdapter = new CustomAdapter (YourPrayerActivity .this, R.layout.activity_row2, projectsCursor, from, to);
Also Change your CustomAdapter as below
class CustomAdapter extends SimpleCursorAdapter {
private LayoutInflater mInflater;
#SuppressWarnings("deprecation")
public CustomAdapter(Context context, int layout, Cursor c, String[] from, int[] to)
{
super(context, layout, c, from, to);
mInflater= LayoutInflater.from(context);
Toast.makeText(YourPrayerActivity.this, "text", 1000).show();
// TODO Auto-generated constructor stub
}
#Override
public void bindView(View view, Context context, final Cursor cursor){
int row_id = cursor.getColumnIndex("_id"); //Your row id (might need to replace)
TextView tv = (TextView) view.findViewById(R.id.text1);
final TextView tv1 = (TextView) view.findViewById(R.id.text2);
int col1 = cursor.getColumnIndex("title");
String title = cursor.getString(col1 );
int col2 = cursor.getColumnIndex("content");
final String content = cursor.getString(col2 );
tv.setText( title);
tv1.setText( content);
Button button = (Button) view.findViewById(R.id.buttonsms);
button.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v){
Log.i("....................",""+cursor.getCount());
Toast.makeText(YourPrayerActivity.this, "text",400000).show();
}
});
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent){
LayoutInflater inflater = LayoutInflater.from(context);
View v = inflater.inflate(R.layout.activity_row2, parent, false);
bindView(v,context,cursor);
return v;
}
}

buttonSMS.setFocusable(false);
set this property

I can't add search feature to my listview - java

In custom adapter it would not work. this code for search will work in SimpleAdapter. For your adapter you have to write custom code for search. Follow this link it would do as per your need (search filter in custom adapetr) Custom Listview Adapter with filter Android
