I'm beginning learn Android. I have issue. I have autocompleteTextView with content is arrayList. Then I want to get position of element in arraylist when I click on autoCompleteTextView. Can you show me do it ?
Thank you so much !
This code !
/* ================= looping through All categories ==================== */
for(int i=0;i<product.length();i++){
JSONObject c = product.getJSONObject(i);
// Storing each json item in variable
pro_id = c.getString(TAG_ID);
pro_name = c.getString(TAG_NAME);
name_product.add(pro_name);
} // end for products
} catch (JSONException e) {
e.printStackTrace();
}
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, name_product);
AutoCompleteTextView textView = (AutoCompleteTextView)findViewById(R.id.result_search);
textView.setThreshold(1);
textView.setAdapter(adapter);
textView.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long rowId) {
//here position is your selected item id
/*String selecteditem =name_product.get(position);
Log.d("Test",selecteditem.toString());
int pos = Integer.parseInt(selecteditem);
Toast.makeText(getApplicationContext(), "cvxcvcv",pos).show();*/
// I want to get position when i click element in autocompletetextView
}
});
Try
autocompletetextview.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long rowId) {
//here position is your selected item id
int selectedposition=position;
}
});

I have a ListView that I populate using the FirebaseListAdapter. Now I want the OnItemClickListener to show the value of the item clicked (the text displayed on the item) in a Toast.
ListView listView;
ListAdapter listAdapter;
mFirebaseRef = new Firebase("https://<firebase root ref>/posts");
mFirebaseQuery = mFirebaseRef.orderByChild("author_id").equalTo(id); //`id` is a variable defined earlier
listAdapter = new FirebaseListAdapter<Post>(this, Post.class, android.R.layout.simple_list_item_, mFirebaseQuery) {
#Override
protected void populateView(View view, Post post) {
String postTopic = post.getTopic();
((TextView) view.findViewById(android.R.id.text1)).setText(postTopic);
}
};
listView = (ListView) findViewById(R.id.postsList);
listView.setAdapter(listAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String topic = String.valueOf(parent.getItemAtPosition(position));
Toast.makeText(getApplicationContext(), "List Item Value: "+topic, Toast.LENGTH_LONG).show();
}
});
Instead of returning the text displayed on the item (as is in the case an ArrayAdapter is used), String.valueOf returns some reference to the model class I use - Post.class.
The output is something like this: com.example.android.model.Post#a1e1874
Can anybody tell me how to get the value of the list item in this case?
AdapterView.getItemAtPosition() returns a Post object, so:
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Post post = (Post)parent.getItemAtPosition(position);
String topic = post.getTopic();
Toast.makeText(getApplicationContext(), "List Item Value: "+topic, Toast.LENGTH_LONG).show();
}
Hi I am working with android.I had created a listview using array list. Now how can I add Action to each list item and also how to get the list position of that item. Please help me, thanks
here is my code
public class MainActivity extends Activity {
private ListView lv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView lv=(ListView)findViewById(R.id.listView1);
ArrayList<String> list=new ArrayList<String>();
list.add("aaaa");
list.add("bbbb");
list.add("cccc");
list.add("dddd");
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
list);
lv.setAdapter(arrayAdapter);
}
}
You need to implement ListView setOnItemClickListener
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// ListView Clicked item index
int itemPosition = position;
// ListView Clicked item value
String itemValue = (String) listView.getItemAtPosition(position);
// Show Alert
Toast.makeText(getApplicationContext(),
"Position :"+itemPosition+" ListItem : " +itemValue , Toast.LENGTH_LONG)
.show();
}
});
For more information go to Documentation.
you can also get the selected item of ListView in setOnItemClickListener using following code:
listView1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
int itemPosition = position;
String itemname = ((TextView)view).getText().toString();
Toast.makeText(getBaseContext(), "Item: " + itemname + " is at position: " + itemPosition, Toast.LENGTH_LONG).show();
}
});
As the listview cells position and the index of arraylist are same. So we can easily get the item from arraylist by the position of cell of listview.
listView1.setOnItemClickListener(new OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
{
int position=position;
String item=marraylist.get(position).toString();
}
}
I used list view to list the items of my SQLite database as follows:
listView = (ListView) findViewById(R.id.listView1);
db.open();
Cursor c = db.getAllHistory();
ArrayList<String> temparr = new ArrayList<String>();
if (c.moveToFirst()) {
do {
temparr.add(c.getString(0)+'\t'+c.getString(1)+'\t'+c.getString(2)+'\t'+c.getString(3)+'\t'+c.getString(4)+'\t');
} while(c.moveToNext());
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, temparr);
listView.setAdapter(adapter);
} else {
db.close();
}
Now I want to access the specific list item by using OnItemClickListener. How should i do it?
To get your perticular data-
Implement setOnItemClickListener()-
and position will return list's item position number:-
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
String yourData = temparr.get(position);
}
});
Just call listView.setOnItemClickListener() with your implementation of the listener.
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
// your code
// Toast.makeText(context,temparr.get(position),Toast.LENGTH_SHORT).show();
}
});
parent -> The AdapterView where the click happened.
view -> The view within the AdapterView that was clicked (this will be a view provided by the adapter)
position -> The position of the view in the adapter.
id->The row id of the item that was clicked.
You can set the listener like this:
Put this code in onCreate()
TextView disp = (TextView) findViewById(R.id.textView1);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String temp = (String) listView.getItemAtPosition(position);
disp.setText(temp);// display on screen
}
});
EDIT:
As you want to display the listItem on screen in a permenant sort of way rather than displaying a toast, the easiest way that you can do this is by adding a TextView in your layout. See the updated code
Hope this helps.
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();
