Creating a text filter (like quick search) for a Spinner in Android
Solution 1
Looks like you are talking about similar functionality given in AutoCompleteTextView
Solution 2
I know this question is old, but today i also needed this function, and because I wasn´t able to find anything, i made myself a adapter for those spinner
The Adapter:
public class Searchspinner extends ArrayAdapter<String> {
private LayoutInflater inflater;
private boolean dropdown = false;
private OnClickListener onsearch;
private ActionBar ab;
private final ArrayList<String> result = new ArrayList<String>();
private InputMethodManager keyboard;
private boolean searching = false;
public Searchspinner(Context context, int resource,
ArrayList<String> objects, LayoutInflater l, ActionBar a,
InputMethodManager imm, String spinnerid) {
super(context, resource, objects);
inflater = l;
ab = a;
keyboard = imm;
createSearch();
// TODO Auto-generated constructor stub
}
@Override
public View getDropDownView(int position, View cnvtView, ViewGroup prnt{
dropdown = true;
return getCustomView(position, cnvtView, prnt);
}
@Override
public View getView(int pos, View cnvtView, ViewGroup prnt) {
dropdown = false;
return getCustomView(pos, cnvtView, prnt);
}
public View getCustomView(int position, View convertView, ViewGroup parent) {
if (!dropdown) {
View mySpinner = inflater.inflate(
R.layout.spinner_ressource_search, parent, false);
TextView main_text = (TextView) mySpinner
.findViewById(R.id.tv_spinner_first);
main_text.setText(getItem(position));
ImageButton search = (ImageButton) mySpinner
.findViewById(R.id.searchbutton);
if (!searching) {
search.setImageResource(R.drawable.search);
} else {
search.setImageResource(R.drawable.search_check);
}
search.setOnClickListener(onsearch);
return mySpinner;
}
View mySpinner = inflater.inflate(R.layout.auftragtextview, parent,
false);
TextView sub_text = (TextView) mySpinner.findViewById(R.id.TextView01);
sub_text.setText(getItem(position));
return mySpinner;
}
private void createSearch() {
onsearch = new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (searching) {
searching = false;
ab.setCustomView(R.layout.actionbar_layout);
ab.getCustomView().setTag("0");
keyboard.toggleSoftInput(0,
InputMethodManager.HIDE_IMPLICIT_ONLY);
for (int i = 0; i < result.size(); i++) {
add(result.get(i));
result.remove(i);
i--;
}
((ImageButton) v).setImageResource(R.drawable.search);
return;
}
((ImageButton) v).setImageResouce(R.drawable.search_check);
searching = true;
ab.setCustomView(R.layout.searchable);
final EditText et = (EditText) ab.getCustomView()
.findViewById(R.id.editText1);
et.setActivated(true);
keyboard.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT,
0);
et.requestFocus();
et.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start,
int before, int count) {
for (int i = 0; i < getCount(); i++) {
if (!getItem(i).contains(s)) {
result.add(getItem(i));
remove(getItem(i));
i--;
}
}
for (int i = 0; i < result.size(); i++) {
if (result.get(i).toLowerCase()
.contains(s.toString().toLowerCase())) {
add(result.get(i));
result.remove(i);
i--;
}
}
}
@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
}
});
}
};
}
}
The spinner_ressource_search.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="@+id/tv_spinner_first"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="TextView" />
<ImageButton
android:id="@+id/searchbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="@android:color/transparent"
android:src="@drawable/search" />
</RelativeLayout>
and the auftragtextview.xml:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/TextView01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="@+d/TextView01"
android:textSize="16sp" >
</TextView>
and this is how you create the Adapter:
Searchspinner auftragSpinnerAdapter = new Searchspinner(
this.getApplicationContext(),
R.layout.auftragtextview,
list_auftragSpinner,getLayoutInflater(),
getActionBar(),
(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)
);
I hope this is going to help anybody, and that i haven´t missed a already build in way to do this :D
Greetings
Edit:
The searcheble.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@drawable/actionbar_background_beosys" >
<EditText
android:id="@+id/editText1"
android:hint="@string/suche"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:layout_marginLeft="15dp"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:layout_marginRight="15dp"
android:singleLine="true"
/>
So the EditText1 is just a simple editText in The View that get´s in the Actionbar when you search.
The ActionbarLayout is the normal ActionbarView.
Solution 3
You can implement it by your self.
Use a button instead of spinner, design a dialog with an EditText
for query input and a ListView
for content of you want to display.
Then filter the content of ListView
according to what user is entered in EditText
.
filter(list, text);
adapter.notifyDataSetChanged();

I'm developing an Android application. I have my activity here with some widgets including a Spinner. I want that Spinner object to be searchable using the quick search button. The idea is that the user tapped the Spinner object and he sees the list (the adapter). If he taps the quick search button he should be provided with a text field to enter a letter and then the spinner list jumps to the fist word it finds with the letter supplied. Just as it works with html and select tags.
I tried google (and SO of course) but it seems that
- no one is interested in a solution like this or
- it is a closely guarded secret. :)
Do you have some pointers in this topic?
-
Adam Arold about 13 yearsWell, the application is using a special Spinner object (extended from Spinner) which has key-value pairs. In addition it must be a dropdown not an edit text field. I don't think that it would work this way.
-
Aritz over 9 years@AdamArold so how could this be the accepted answer? Spinners allow selection even though no input value introduced.

Adam Arold over 9 yearsAs you can see this question is 3 years old. I don't use Android for like 1 year so it is not relevant anymore.

ShahiM almost 9 yearswhat are the
searchable
,actionbar_layout
andeditText1
items?? -
Juliatzin over 8 yearsactionbar_layout is still not defined in the answer

Gabriel almost 7 yearsThat's a really nice solution! No need for 3rd library
