How can I get a item from a listView 2 items , I am using to fill the listView a database of queries but there do not know how to do that to get the name of the item ?
from = new String[]{manager.CN_NAME,manager.CN_CREDITS};
to = new int[]{android.R.id.text1,android.R.id.text2};
manager = new DataBaseManager(this);
listaMateria = (ListView) findViewById(R.id.listView);
cursor = manager.cargarCursorMateria();
adapter = new SimpleCursorAdapter(this,android.R.layout.two_line_list_item,cursor,from,to,0);
listaMateria.setAdapter(adapter);
listaMateria.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//String item = ((TextView)view).getText().toString();
String a = Integer.toString(to[position]);
Toast.makeText(getBaseContext(), a, Toast.LENGTH_LONG).show();
}
});
You could also get the cursor for that row.
public void onItemClick(AdapterView<?> parent,
View view, int position, long id) {
Cursor cursor = (Cursor)adapter.getItem(position);
String value = cursor.getString(cursor.getColumnIndex("column_name"))
}

Currently, the code i have only displays the data (on a new activity when clicked) at index 0 of that list view - not the item i actually clicked. i would like to somehow change my code so it can display the data at index n (n being the item i clicked in list view):
ResultsActivity.java
final ArrayList<String> searchResults = getValuesFromJSON(jsonResult);
final ListView listView = (ListView) findViewById(R.id.listView);
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>
(this, android.R.layout.simple_list_item_1, searchResults);
listView.setAdapter(arrayAdapter);
//list items become clickable and open the movie detail page which displays the movie data of the specific movie
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent newActivity = new Intent(ResultsActivity.this, MoviePage.class);
newActivity.putStringArrayListExtra("movie data", searchResults);
startActivity(newActivity);
}
});
}
MoviePage.java
ArrayList<String> searchResults = getIntent().getStringArrayListExtra("movie data");
TextView t = (TextView)findViewById(R.id.textViewfinal);
t.setText(searchResults.get(9));
Just set a onclick listener on your listview so you can listen for item click events.
Put this in your onCreate method in your activity:
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
//you can move the textview to a class variable if you want
TextView t = (TextView)findViewById(R.id.textViewfinal);
t.setText(searchResults.get(position));
}
});
update: you'll want to pass the position to the next activity the same way your passing the searchResults to MoviePage so just do this:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent newActivity = new Intent(ResultsActivity.this, MoviePage.class);
newActivity.putStringArrayListExtra("movie data", searchResults);
newActivity.putExtra("position",position);//pass the position to the next activity
startActivity(newActivity);
}
});
now in MoviePage.java
ArrayList<String> searchResults = getIntent().getStringArrayListExtra("movie data");
int position = getIntent().getIntExtra("position",0);
TextView t = (TextView)findViewById(R.id.textViewfinal);
t.setText(searchResults.get(position));
Try this :
ResultsActivity.java
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent newActivity = new Intent(ResultsActivity.this, MoviePage.class);
newActivity.putExtra("movie data", searchResults.get(position));
startActivity(newActivity);
}
});
MoviePage.java
Bundle extras = getIntent().getExtras();
if (extras != null) {
TextView t = (TextView)findViewById(R.id.textViewfinal);
t.setText(extras.getString("movie data"));
}
I have an OnItemClick(), after that I wanted to get the ItemClicked name's and display it in a TextView.I do it normally, but the problem is that I get the ItemClicked name's inside a bracket! How do I avoid this?Here is the output:
{titre=hello}
I want only in my TextView:
hello.
Here is the code:
public void onItemClick(AdapterView<?> parent, View view, int position, long id ) {
displayTextViewTitle = (TextView)findViewById(R.id.text_view_title);
Object item = parent.getItemAtPosition(position);
String value = item.toString();
displayTextViewTitle.setText(String.valueOf(value));
}
Try this :
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
TextView displayTextViewTitle = (TextView) findViewById(R.id.textView1);
TextView item = (TextView) parent.getItemAtPosition(position);
String value = item.getText();
displayTextViewTitle.setText(value);
}
or even better try :
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
TextView displayTextViewTitle = (TextView) findViewById(R.id.textView1);
ListView lv = (ListView) findViewById(yourListViewName);
String value = lv.get(position).tostring();
displayTextViewTitle.setText(value);
}
If you are getting your String {titre=hello} like this after click on ListView. then you should use this:
String[] no = item.split("=");
String m = no[0];
String k = no[1];
String name = k.substring(0, k.length() - 1);
name is your final result String .
value is already a String, you don't have to use String.valueOf(value).
The listener method works fine, check this:
public class SplashActivity extends Activity implements OnItemClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
ListView lv = (ListView)findViewById(R.id.lv);
ArrayList<String> members = new ArrayList<String>();
members.add("titre=hello");
members.add("world");
ArrayAdapter s = new ArrayAdapter(this, android.R.layout.simple_list_item_1, members);
lv.setAdapter(s);
lv.setOnItemClickListener(this);
}
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
TextView displayTextViewTitle = (TextView) findViewById(R.id.textView1);
Object item = parent.getItemAtPosition(position);
String value = item.toString();
displayTextViewTitle.setText(String.valueOf(value));
}
}
Recheck the values inside your listview, the problem might be there
My current problem is I have a ListView I'm using to display my contacts now I'd like to set the onItemClick to grab the name of the contact and set that to a TextView called p2 the code I currently have is:
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.setp2);
cursor = managedQuery(ContactsContract.Contacts.CONTENT_URI,null,null,null,null);
String[] from = new String[]{ContactsContract.Contacts._ID,ContactsContract.Contacts.DISPLAY_NAME};
int[] to = new int[]{R.id.id_text,R.id.name_text};
final SimpleCursorAdapter adapter = new SimpleCursorAdapter(setp2.this,R.layout.setp2_layout,cursor,from,to);
ListView list = (ListView)findViewById(R.id.contact_list);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
}
});
}
So basically I'm unsure of what I need to do in the onItemClick, any help appreciated!
In your onItemClick, you will get the instance of the view associated with that list item.From that view you can get the text associated with it and set it to the p2 TextView. If my understanding of your requirement is correct, the code will be something like this:
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
CharSequence name = ((TextView)view.findViewById(R.id.name_text)).getText();
//Set this to your textview in P2
tvP2.setText(name);
}
});
Set up a SimpleCursorAdapter.CursorToStringConverter and set it on the adapter, then use convertToString(Cursor cursor) to get the text in on item click :
(Cursor) simple.getItem(position)
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
cursor.moveToPosition(position);
String name = cursor.getString(cursor.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME));
p2.setText(name);
}
});
I have an array (array1 with States) and AutoCompleteTextview in which I'm filling it with array1. When I select the value from AutocompleteTextView I select a state from AutoCompleteTextView Dropdown
What I want is to get the position of the item from array1 which I've selected.
What I've tried is OnClickEvent of AutocompelteTextView.
STATE.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long rowId) {
String selection = (String) parent.getItemAtPosition(position);
String num = selection;
}
});
It ss giving me the value which I selected from dropdown but i want to get the position of the value in array1. For Example I have an array of size 4, like array1 = {A,B,C,D}, and if I select B it should return me B position in Array i.e 2.
I hope I made it clear. Thanks in advance.
Use the position variable in the onItemClick.
STATE.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long rowId) {
String selection = (String) parent.getItemAtPosition(position);
int pos = -1;
for (int i = 0; i < yourarray.length; i++) {
if (yourarray[i].equals(selection)) {
pos = i;
break;
}
}
System.out.println("Position " + pos); //check it now in Logcat
}
});
Use List instead of Array. Implement onItemClickListener for AutoCompleteTextView, then use indexOf on your list to find the index of selected item.
actvCity.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
int index = cityNames.indexOf(actvCity.getText().toString());
// Do Whatever you want to do ;)
}
});
#Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id)
{
TextView txtvw=(TextView) view;
String str=txtvw.getText().toString();
int index = contactNames.indexOf(str);
}
Item.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//// id contains item if from database
ItemNoSelected = id;
}
});
id is from database, we can use that
You can find the parent string in the clickItem listener.
OSchools in this case is the custom ArrayList.
Object item = parent.getItemAtPosition(position);
for(OSchools d : data){
Log.e("name",d.getName());
String name = d.getName();
if(d.getName() != null && name.contains(item.toString())){
ID = d.getID();
}
is possible get the value of a single row.
In partycular i wont get in a string the value of id in my row of mt list with adapter.
In each row there are value id and label
Thaks a lot and sorry for my english
ListView list;
list = (ListView) findViewById(R.id.listView1);
mSchedule = new SimpleAdapter(getApplicationContext(), result ,R.layout.row_meteo,
new String[]{"id", "label"}, new int[] {R.id.textView1,R.id.textView2});
list.setAdapter(mSchedule);
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String idPlace = mSchedule.getItem(position).toString();
Toast.makeText(getApplicationContext()," Cliccato sul luogo :"+idPlace,Toast.LENGTH_LONG).show();
}
}
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
TextView tv = (TextView)view.findViewById(R.id.textView1); //<---------
String str = tv.getText();
}
Replace
String idPlace = mSchedule.getItem(position).toString();
with
String idPlace =((TextView)view.findViewById(R.id.textView1)).getText().toString();
