I am trying to implement a contact list with a search and marking feature; everything except search is working properly. The code I am using is given below. Could someone please help me to sort this out?
public class MainActivity extends ListActivity implements Runnable {
Cursor phoneCursor;
public static Button done;
ListView lv;
/* OpenHelper db_obj;*/
final int PROGRESS_DIALOG = 0;
ProgressDialog progressDialog;
ArrayAdapter<ContactModel> adapter;
ArrayList<HashMap<String, String>> CONTACT_DATA = new ArrayList<HashMap<String, String>>();
#Override
public void onCreate(Bundle saveinst) {
super.onCreate(saveinst);
progressDialog=ProgressDialog.show(MainActivity.this, "LoadContacts", "Please wait...", true, false);
Thread loadContact = new Thread(this);
loadContact.start();
}
public void run() {
List<ContactModel>contactList = new ArrayList<ContactModel>();
try {
Looper.prepare();
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
null, Phone.DISPLAY_NAME + " ASC");
while (phones.moveToNext()) {
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber11 = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
contactList.add(get(name,phoneNumber11));
}
adapter = new MyContactListAdapter(MainActivity.this, contactList);
handler.sendEmptyMessage(0);
} catch(Exception exce) {
exce.printStackTrace();
}
private final Handler handler = new Handler() {
#Override
public void handleMessage(Message msg) {
progressDialog.dismiss();
setListAdapter(adapter);
setContentView(R.layout.activity_main);
EditText editText;
/* db_obj = new OpenHelper(getApplicationContext());*/
lv = getListView();
editText = (EditText)findViewById(R.id.editText1);
editText.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
// When user changed the Text
MainActivity.this.adapter.getFilter().filter(cs);
setListAdapter(adapter);
}
#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
}
});
done = (Button)findViewById(R.id.button1done);
done.setVisibility(View.INVISIBLE);
done.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
MainActivity.this.finish();
Intent in = new Intent();
in.setClass(getApplicationContext(), MainActivity.class);
startActivity(in);
}
});
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
System.out.println("Entered List Activity");
}
});
}
};
public ContactModel get(String name,String number)
{
return new ContactModel(name,number);
}
Instead of an EditText try an AutoCompleteTextView. It works similar to what you have here except the searching is handled by Android without have to use filters in the onTextChanged.
myACTV.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
myACTV.showDropDown();
myACTV.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3)
//Do something here
}
});
return false;
}
});

#Override
public void onBackPressed() {

startActivity(i);
}
}
This is my updated code, it filtered the data but using the last field, not by name field... it took the last field for filtering, if any know the answer plz do share
Try this ...
Search_By_Name .addTextChangedListener(new TextWatcher() {
#Override public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
String text = search.getText().toString().toLowerCase(Locale.getDefault()); //
Your_Activity.this.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
} });

I am trying to make a listView search for Android.I am using SimpleCursorAdapter on onTextChanged
i have found a error adapter cannot be resolved or is not a field.how can resolve this error .I am using SimpleCursorAdapter .I am not able to use adapter.getFilter().filter(cs);
ListView lv;
Cursor cursur1;
EditText search ;
int textlength=0;
ArrayAdapter<String> adapter1;
#SuppressWarnings("deprecation")
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
search = (EditText) findViewById(R.id.inputSearch);
final String [] from={ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,ContactsContract.CommonDataKinds.Phone.NUMBER,ContactsContract.CommonDataKinds.Phone._ID};
int [] m={android.R.id.text1,android.R.id.text2};
lv=getListView();
lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
cursur1=getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
startManagingCursor(cursur1);
#SuppressWarnings("deprecation")
SimpleCursorAdapter adapter=new SimpleCursorAdapter(this, android.R.layout.simple_list_item_2, cursur1, from,m);
setListAdapter(adapter);
search.addTextChangedListener(new TextWatcher() {
#Override

}
#Override

}
}
Try this.. inside add Text change listener
YourAdapterOrWhateverAdapter adapter = (YourAdapterOrWhateverAdapter) listView.getAdapter();
adapter.getFilter().filter(s);
adapter.notifyDataSetChanged()
you can use AutoCompleteTextView, e.g -
private static final String[] DATE_RANGE = new String[] { "1 Day",
"2 Days", "3 Days", "6 Months", "1 Year", "Blank" };
AutoCompleteTextView dateRangeTV = (AutoCompleteTextView)findViewById(R.id.tv_date_range);
dateRangeTV.setThreshold(0);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
R.layout.default_date_range_list, DATE_RANGE);
dateRangeTV.setAdapter(adapter);
In Touch event, you could see the dropdownlist :
dateRangeTV.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
dateRangeTV.showDropDown();
return false;
}
});
Type any text, It'll show your matching text from the list.
For more see the tutorial of the AutoCompleteTextView
I have this Listview:
#Override
public void onComplete(List<Profile> friends) {
runOnUiThread(new Runnable() {
#Override
public void run() {
mSpinner.setVisibility(View.GONE);
mSpinner.clearAnimation();
}
});
// populate list
List<String> values = new ArrayList<String>();
for (Profile profile : friends) {
//profile.getInstalled();
values.add(profile.getName());
}
listView = (ListView) findViewById(R.id.list);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> av, final View view, final int i, long i2) {
Animation pushLeftIn = AnimationUtils.loadAnimation(CallActivity.this, R.anim.jump_no_fade);
view.startAnimation(pushLeftIn);
}
});
ArrayAdapter<String> friendsListAdapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.list_items2, values);
friendsListAdapter.sort(new Comparator<String>() {
#Override
public int compare(String lhs, String rhs) {
return lhs.compareTo(rhs);
}
});
mFriendsList.setAdapter(friendsListAdapter);
}
};
I am trying to make the edittext filter the listview, this is what i have tried:
mySearchView.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
// When user changed the Text
CallActivity.this.friendsListAdapter.getFilter().filter(cs);
}
#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
}
});
I get no errors in the code but when i try to search in the edittext it doesn't work at all, what is the problem or how should i do instead?
Try do it in afterTextChanged(Editable arg0).
And did you implement your getFilter().filter(cs). Can you show implementation?
I am new to Android programming and I have a ListView when filtered always return me the first item in the list, so how do I fix this?
For instance, my list contains A.A, A.B, A.C, B.C, B.D.
When I want to search the list for things starting with B, I will get B.C, B.D but when I click B.C, it returns me A.A and B.D, it returns me A.B
public class PatientList extends Activity{
PatientDB patientDB;
Context myContext;
ListView lv_patients;

}
});

lv_patients.setAdapter(adapter);

// When user changed the Text

}
public void afterTextChanged(Editable arg0) {

}
}
Because you filter your adapter to have B.C in position 0 and B.D in position 1. But in your implementation of your onClickListener, you use the listview's position to get directly from the source ArrayList.
String a = patientArrayList.get(position);
Instead to get it from the filtered adapter:
String a = parent.getAdapter().getItem(position);
or
String a = parent.getItemAtPosition(position);
I have a listview of different data which are stored in DB and when i click particular data it will show the details of that and also i have used adapter class through position of the listview, it gets the detail of the data to display.
I need to add search for the listview and from the result listview, if i click the data it should show the details. please, can any one provide the code for this.

You can make use of FilterQueryAdapter interface as below:
DataBaseHelper myDbHelper = new DataBaseHelper(this);
FilterQueryProvider fqp = new myFilterQueryProvider(myDbHelper);
<YourCursorAdapter>.setFilterQueryProvider(fqp);
<YourListView>.setTextFilterEnabled(true);
<YourEditTextSearchbox>.addTextChangedListener(new TextWatcher()
{
#Override
public void onTextChanged(CharSequence s, int start,
int before, int count) {
// TODO Auto-generated method stub
}
#Override
public void beforeTextChanged(CharSequence s, int start,
int count, int after) {
// TODO Auto-generated method stub
}
#Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
this.adaptr.getFilter().filter(s);
}
});
public class myFilterQueryProvider implements FilterQueryProvider {
DataBaseHelper myDbHelper;
public myFilterQueryProvider(DataBaseHelper mdb) {
myDbHelper = mdb;
}
public Cursor runQuery(CharSequence constraint)
{
try {
myDbHelper.openDataBase();
}catch(SQLException sqle){
throw sqle;
}
sql =""; //Your DB Query here
Cursor cursor = myDbHelper.getLobbyView(sql);
return cursor;
}
}
If you are working with a DB
simply get one Edittext textwatcher.
Every textchanged call db "LIKE" query to show your results
