This is the code for my AutoCompleteTextView :
String[] countries = getResources().getStringArray(R.array.countries_array);
final ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.item_list ,countries);
textView = (AutoCompleteTextView) dialog.findViewById(R.id.autoCompleteTextView1);
adapter.setNotifyOnChange(true);
textView.setAdapter(adapter);
This is item_list :
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp"
android:textColor="#000"
android:drawableRight="#drawable/arrow">
and this is the output :
I want to change this pop-up kind of suggestion box , and want to show the suggestion list a little bit below from the AutoCompleteTextView ..similar to this : (please disregard the apple design, it’s just about where the results appear)
How can i do this ..Please suggest .
Thanks.!!
Use the android:dropDownAnchor, android:dropDownHorizontalOffset, android:dropDownVerticalOffset and maybe others on the AutoCompleteTextView in your layout. See AutocompleteTextView.
I used a ListView below the AutoCompleteTextView. I added my custom adapter to both the ListView and the AutoCompleteTextView. I the set the height and width of the AutoCompleteTextView dropdown to 0:
myListView.setAdapter(myCustomAdapter);
myAutoComplete.setAdapter(myCustomAdapter);
myAutoComplete.setDropDownHeight(0);
myAutoComplete.setDropDownWidth(0);
Since the listview is also attached to the same adapter it'll get updated when you update the autocomplete.
u need QSB (Quick search box).
refer to this http://developer.android.com/resources/articles/qsb.html
It needs a ContentProvider to fill the QSB data.

When we build a ListView in android studio, we need to use an ArrayAdapter.
What is the task of second argument in constructor of ArrayAdapter ?
I cannot understand what is android.R.layout.simple_list_item_1 used for ?
This layout describe how the item list looks like.Maybe you want every item contain a text view and image.You should specify these details in this layout.
android.R.layout.simple_list_item_1 is a layout in which the data from your ArrayAdapter gets populated(added).
This is the id of the layout that you need to use for populating each of the item in the list. If it says android.R.layout that means you are going to use one of the standard android layouts. simple_list_item_1 This is the name of the file which will populate each row of the list. try changing this to simple_list_item_2 to see how the layout in list changes.
You can also use your custom adaptors and custom layouts(which would be in majority of the cases in day to day apps).
For full list of standard layouts available Go here
This argument defines how list items would appear in ListView, There are many layouts you can also try them out or you can make your own custom layout to modify apperance of listitems in Listview by using CustomAdapter.
1.create custom layout name custom_layout.xml & paste bellow code
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textSize="16sp" >
</TextView>
Use like R.layout.custom_layout instead of android.R.layout.simple_list_item_1
In my app I have a scenario and that is I want to show the user the desired range of numbers and these would be dynamic , let say 1,2,3 or some time ,1,2 or some time 1,2,3,4,5 I want user to select on of the number from my given range. so that I dont want user to fill by typing numbers. Please tell me how to achieve this and How can i control the range of numbers in autocomplete textview .
or what is alternate of this. Just keep in mind I have Edittext , and in that edittext I want user to select the number not just enter the number.
You can use AutoCompleteTextView in your layout:
XML Code
<AutoCompleteTextView android:id="#+id/EdtSearch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
JAVA Code
To bind array inside AutoCompleteTextView use the following code
AutoCompleteTextView EdtSearch = (AutoCompleteTextView) findViewById(R.id.EdtSearch);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, rangesyouwantasStringArray);
EdtSearch.setAdapter(adapter);
Why don't you use a Spinner? I think that for your purposes it is more efficient.
You can change your EditText to a Spinner and with its adapter, change the range programmatically.
Edit:
Here is the element that you have to insert instead of the edittext
<Spinner android:id="#+id/spinner"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
Then, in your Activity/Fragment code:
Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1);
spinner.setAdapter(adapter);
// Here add the range of numbers. For example:
for (int i = 0; i < 5; i++) {
adapter.add(Integer.toString(i));
}

Spinner does not wrap text -- is this an Android bug?
(15 answers)
Closed 3 years ago.
I have two spinner and EditText controls within a table layout view on a separate row. The spinners are populated with data. My problem is the data (texts) that are populated into the spinners are too lengthy to fit the screen size. Therefore, the spinners are forced to stretch unnecessarily stretching other controls on another row.
It's a must for me to show the texts in the spinner. Hence using ellipses is not an option. If it's possible how can I wrap the lengthy text on the spinners?
Step 1. TextView with wrapped text
The first thing to do is to to force simple TextView to wrap text. Its easy:
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:singleLine="false"
android:text="very long text that will be wrapped to next line" />
Note the singleLine attribute here.
Step 2. Custom layout
Now we should somehow set singleLine attribute to false in TextView used by Spinner to show the item in the list.
In your code you probably have place where you create adapter to use it with Spinner:
this.mAdapter = ArrayAdapter.createFromResource(this, R.array.Planets,
android.R.layout.simple_spinner_dropdown_item);
The idea is to copy the android.R.layout.simple_spinner_dropdown_item layout to your project. Then modify it by setting singleLine attribute to false in CheckedTextView:
For this, add file to res/layout folder named multiline_spinner_dropdown_item.xml with next code:
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
style="?android:attr/spinnerDropDownItemStyle"
android:singleLine="false"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:ellipsize="marquee" />
Note that this file is identical to android.R.layout.simple_spinner_dropdown_item layout, except it has singleLine set to false now.
Step 3. Creating Adapter with custom layout
Modify your adapter creating code to:
this.mAdapter = ArrayAdapter.createFromResource(this, R.array.Planets,
R.layout.multiline_spinner_dropdown_item);
Here is screenshot from modified SpinnerActivity example from Android SDK:
Define a custom layout and use it with the spinner and adapter.
Hi I have a spinner, which contains radio button elements. My spinner loads the elements, but everything is invisible. I think you can understand my situation from the image. an I get any suggestions.
This is the code I am using,
String[] reminder={"5 minutes","10 minutes","15 minutes","20 minutes","25 minutes","30 minutes","35 minutes","45 minutes"};
spinnerAdapter = new ArrayAdapter<String>(mContext,
android.R.layout.simple_spinner_item, reminder);
spinnerAdapter
.setDropDownViewResource(android.R.layout.simple_list_item_single_choice);
reminder_spinner.setPrompt("Reminders");
reminder_spinner.setAdapter(spinnerAdapter);
reminder_spinner.setOnItemSelectedListener(new ItemSelect());
The fact that the item text shows up when it is selected leads me to believe it could be a styling issue, ie white font on white background. Here is the layout for simple_spinner_dropdown_item:
<CheckedTextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
style="?android:attr/spinnerDropDownItemStyle"
android:singleLine="true"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"/>
I would define another xml layout using the above as a template, and pass that to setDropDownViewResource instead.
add this
spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);`
in your code and remove
spinnerAdapter.setDropDownViewResource(android.R.layout.simple_list_item_single_choice);`
I have a selection for some items using a spinner widget. At the moment the spinner will load a simple Textview and show the name of the item.
It is possible to define an own view to show inside the spinner row? I would suspect it being similar to a custom List row.
I simply want to show an individual icon left from the spinner text for each item in the list.
Yes, you can do that - as you may know, Spinner is a type of AdapterView, which means that you can adapt your own data to show in such View.
The approach is pretty similar to the one with ListView.
Excerpt from ApiDemos:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, INTERPOLATORS);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
s.setAdapter(adapter);
You can define your own layout and pass it to the SpinnerAdapter subclass that you use.
Yes, it is very easy.
The main thing is that, define TextView as the root element in the layout file.
Do as below:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, INTERPOLATORS);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
s.setAdapter(adapter);
simple_spinner_dropdown_item.xml file :
<?xml version="1.0" encoding="utf-8"?>
<TextView>
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="50px"
android:textColor="#000000"
android:textSize="20px"
android:gravity="center_vertical" >
</TextView>
