How can i change the spinner title bar style.
I wish to change the title bar for the following items:

title textsize,textColor and
background color
How can i do this?
please help me...i have searched google and more sites.am not getting any solution for this.so please let me know its possible.if possible means how can i develop this????please explain me.
EDIT:
This is my code:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
R.layout.row, R.id.country, list);
spinner.setPrompt("Choose a Status");
// spinner.setTextColor("#FF0000");
spinner.setAdapter(adapter);
adapter.notifyDataSetChanged();
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
}

You have to create CustomSpinner,
To do so try this following way, it works well for me
Step 1: Create Custom Spinner Class
class CustomSpinnerAdapter extends CursorAdapter {
LayoutInflater mInflater;
private int cocktailname;
CustomSpinnerAdapter(Context context, Cursor cursor)
{
super(context, cursor);
mInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
cocktailname = cursor.getColumnIndex(YourDatabase.CK_NAME);
}
#Override
public View newDropDownView (Context context, Cursor cursor, ViewGroup parent)
{
return mInflater.inflate(R.layout.dropdownspinnertext, parent, false);
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent)
{
return mInflater.inflate(R.layout.spinnertext, parent, false);
}
#Override
public void bindView(View row, Context context, Cursor cursor)
{
//Setting the Value here
TextView paymentname = (TextView) row.findViewById(R.id.text1);
paymentname.setTypeface(textFont);
String cocktail = cursor.getString(cocktailname);
paymentname.setText(cocktail);
}
}
Step 2 : Call this Adapter
CustomSpinnerAdapter custom_spinneradapter = new CustomSpinnerAdapter(this,youcursor);
spnListCocktails.setAdapter(custom_spinneradapter);
spnListCocktails.setOnItemSelectedListener(this);
Xml for dropdownspinnertext
I am using Checked Dropdown Spinner
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/text1"
style="?android:attr/spinnerDropDownItemStyle"
android:singleLine="true"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:textColor="#FFFFFF"
android:textSize="18sp"
android:background="#drawable/background_image"
/>
For spinnertext.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/text1"
style="?android:attr/spinnerItemStyle"
android:singleLine="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:gravity="center"
android:padding="4dip"
android:layout_marginLeft="10dip"
android:textSize="20sp"/>
Hope it helps

Using Java (Code):
spinner.setPrompt("Title")
OR
From XML:
android:prompt="#string/spinner_title

How can I attach a delete button (x) to each member of a dynamically created ListView?

I have a dynamically created list. It's fragment-layout is as follows:
<ListView
android:id="#+id/colorsList"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
When I add a row to the listview, I want an "X" mark to appear at the end of the row so that when the user clicks on the "X", the row gets deleted.
Not sure, if its relevant but, the way I am adding and removing rows to the listview is as follows.
Logic to add a row tot he listView:
#BindView(R.id.understood_languages_list)
View mColorsList;
*********
*********
ListView listFavoriteColors;
listFavoriteColors = (ListView) mColorsList;
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(context, android.R.layout.simple_list_item_1, getColorsList());
listFavoriteColors.setAdapter(arrayAdapter);
Logic to remove a row from the ListView.
listFavoriteColors.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
initializeView();
arrayAdapter.remove(((TextView)view).getText().toString());
}
});
Any helpful suggestions on how this can be achieved is much appreciated.
User Custom Adapter with custom Layout to attach delete button to each item in listview
try this code :
CustomAdapter
public class ListAdapter extends ArrayAdapter<String> {
private int resourceLayout;
private Context mContext;
ListInterFace interface;
public ListAdapter(Context context, int resource, List<String>
items,ListInterFace interface) {
super(context, resource, items);
this.resourceLayout = resource;
this.mContext = context;
this.interface=interface;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(mContext);
v = vi.inflate(resourceLayout, null);
}
String value= getItem(position);
if (value!= null) {
TextView tt1 = (TextView) v.findViewById(R.id.dummytext);
Button cancel_click=v.findViewById(R.id.cancel_click);
if (tt1 != null) {
tt1.setText(value);
}
//remove item on button click
cancel_click.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view){
interface.removeItem(position);
}
})
}
return v;
}
}
R.layout.itemlistrow defines the row of the ListView.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context=".MainActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/dummytext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Dummy"
android:textColor="#android:color/black"
android:textSize="18sp"
android:padding="5dp"/>
<ImageView
android:id="#+id/cancel_click"
android:layout_width="20dp"
android:layout_height="20dp"
android:src="#mipmap/cancel"
android:layout_alignParentRight="true"
android:layout_margin="5dp"/>
</RelativeLayout>
</LinearLayout>
In the MainActivity define ListViewlike this,
ListView yourListView = (ListView) findViewById(R.id.itemListView);
// get data from the table by the ListAdapter
ListAdapter customAdapter = new ListAdapter(this, R.layout.itemlistrow, myList, new ListInterFace () {
#Override
public void removeItem( int position) {
myList.remove(position);
customAdapter .notifyDataSetChanged();
});
yourListView .setAdapter(customAdapter);
InterFace
public interface ListInterFace {
void removeItem(int position);
}

Customize spinner that is in the menu or Action Bar

I know how to customize the spinner. In my case it is a little bit different. I cannot modify my code more than I have now. Normally, I am able to make spinner that is reachable from all activities in my app.
I am trying to put icon along the textview in the spinner drop down.
Here the code I have;
Spinner.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="fill_parent" >
<Spinner
android:id="#+id/spinner"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:drawSelectorOnTop="true"
android:spinnerMode="dialog"
android:prompt="#string/language_prompt" />
spinner_row.xml
<?xml version="1.0" encoding="utf-8"?>
<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:addStatesFromChildren="true"
android:gravity="center_horizontal"
android:padding="5dp"
android:textColor="#FFFFFF"
android:textSize="17sp" >
</TextView>
<!-- Here I cannot use Relative layout. If I use it gives error like [java.lang.ClassCastException: android.widget.ImageView cannot be cast to android.widget.TextView]. Without layout I cannot implement ImageView. I am stuck here.
My activity class;
public class Base_Activity extends Activity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
//int flags = R.array.flags;
final Spinner spinner = (Spinner) menu.getItem(0).getActionView()
.findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.languages, R.layout.spinner_row);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
What I want is to make is custom Adapter so that I can put image along the textview in spinner list. I am not able to make normal way that I checked in many tutorials. I think it's because I am creating spinner in onCreateOptionsMenu() constructor.
u can take a look at this tutorial on AndroidHive
http://www.androidhive.info/2013/11/android-working-with-action-bar/
code snippet
// Spinner title navigation data
navSpinner = new ArrayList<SpinnerNavItem>();
navSpinner.add(new SpinnerNavItem("Local", R.drawable.ic_location));
navSpinner
.add(new SpinnerNavItem("My Places", R.drawable.ic_my_places));
navSpinner.add(new SpinnerNavItem("Checkins", R.drawable.ic_checkin));
navSpinner.add(new SpinnerNavItem("Latitude", R.drawable.ic_latitude));
// title drop down adapter
adapter = new TitleNavigationAdapter(getApplicationContext(),
navSpinner);
getView() and getDropDownView() from TitleNavigationAdapter
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.list_item_title_navigation, null);
}
imgIcon = (ImageView) convertView.findViewById(R.id.imgIcon);
txtTitle = (TextView) convertView.findViewById(R.id.txtTitle);
imgIcon.setImageResource(spinnerNavItem.get(position).getIcon());
imgIcon.setVisibility(View.GONE);
txtTitle.setText(spinnerNavItem.get(position).getTitle());
return convertView;
}
#Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.list_item_title_navigation, null);
}
imgIcon = (ImageView) convertView.findViewById(R.id.imgIcon);
txtTitle = (TextView) convertView.findViewById(R.id.txtTitle);
imgIcon.setImageResource(spinnerNavItem.get(position).getIcon());
txtTitle.setText(spinnerNavItem.get(position).getTitle());
return convertView;
}
Download that code and u r good to go

What am I doing wrong?
Thanks
Just one minor change in your code and BOOOM your code will listen to you list click event
final PopupWindow popupWindow = new PopupWindow(popupView,
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT,true);
You forget to mention focusable setting true in PopupWindow constructor.
had the same problem, but in my case setFocusble(false) was required (and using ListPopupWindow was not a solution in my case as a lot of stuff in the project already used base PopupWindow's functionality including extending).
If someone in the same situation there is a kind of workaround based on bug discusson here (post #9)
The main idea is that ListView's hierarchy is still receives touch events so we can manually trigger onItemClick().
However this approach is not 100% identical to real ListView's touch handling (like there is no glow of selection while tapping a row) this done pretty well for me for the moment.
If someone has more precise solution of this problem, please share.
So, here is complete Adapter's code which can be used with ListView inside PopupWindow which is setFocusable(false):
private class CustomAdapter extends ArrayAdapter {
private LayoutInflater mInflater;
private ListView mOwningListView;
public CustomAdapter(Context context, List<String> objects, ListView listView) {
super(context, android.R.layout.simple_list_item_1, objects);
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mOwningListView = listView;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = mInflater.inflate(R.layout.font_pick_row, null);
}
// this is the key point of workaround
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
/*
* as every row is still receiving their touches
* we can use this to manually trigger onItemClick
* since it doesn't firing in popupWindow.setFocusable(false)
*/
mOwningListView.getOnItemClickListener().onItemClick(mOwningListView, v, position, getItemId(position));
}
});
//... other stuff
return convertView;
}
}
May this help you

Declare listview and list onClickListener outside the button ClickListener.

Resource Id for Text View error while attaching image

in my spinner i am trying to attach an image and a text View,
Following is my layout xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<ImageView
android:id="#+id/UICurrencyCurrencyFlag"
android:layout_height="20dp"
android:layout_width="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:src="#drawable/cross_btn" />
<TextView
android:id="#+id/UICurrencyCurrencyName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:textStyle="bold"
android:layout_toRightOf="#+id/UICurrencyCurrencyFlag"
android:text="TextView" />
</RelativeLayout>
Following is the constructor i am using for my Custom Array Adapter
public class CustomArrayAdapterForCurrencies extends ArrayAdapter<CharSequence>
{
private final Activity context;
public final CharSequence[] keys;
public CustomArrayAdapterForCurrencies(Activity context, CharSequence[] keys)
{
super(context, R.layout.ui_currency_layout,keys);
this.context = context;
this.keys = keys;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = null;
LayoutInflater inflator = context.getLayoutInflater();
view = inflator.inflate(R.layout.ui_currency_layout, null);
final ViewHolder viewHolder = new ViewHolder();
When my activity starts, spinner does show image and text but when i try to select spinner it gives error that Adapter need resouce id for the text view
How can i resolve this issue,
Best Regards
You should add this(row layout) in getView(...) in your CustomArrayAdapterForCurrencies
see this tuts.... http://android-er.blogspot.in/2010/12/custom-arrayadapter-for-spinner-with.html
Change your super statement to
super(context, R.layout.ui_currency_layout, R.id.YourTextId , keys);

Why isn't my listview selectable?

I have a custom CursorAdapter and it looks like :
public class LabelAdapter extends CursorAdapter {
Context con;
LayoutInflater mFactory;
public AlarmTimeAdapter(Context context, Cursor c) {
super(context, c);
con = context;
mFactory = LayoutInflater.from(con);
}
#Override
public void bindView(View view, final Context context, Cursor cursor) {
final String label2 = cursor.getString(AlarmData.ALARM_TITLE_INDEX);
..code to fill in the textview with whats in the cursor
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View ret = mFactory.inflate(R.layout.item_lv, parent, false);
return ret;
}
}
my item_lv looks like:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingBottom="10dp"
android:focusable="true"
>
<TextView
android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="14dp"
android:textAppearance="?android:attr/textAppearanceSmall" />
</RelativeLayout>
When I call :
ListView lv = (ListView)findViewById(R.id.listview); //Listview is in the main.xml file
lv.setAdapter(new LabelAdapter(this, mCursor);
lv.setFocusable(true);
The items in the listview aren't selectable.. does anyone know whats wrong? I've set the items focusable, but they aren't able to be clicked. Help! Thanks!
Set onItemClickListener to your listView-
lv.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> adapter, View view, int position,
long arg3) {
});
Remove android:focusable="true" from RelativeLayout for your item.
I believe the answer is really simple. Set the textview in the .xml should be
Android:Clickable = "True"
Reason for this is that if you are putting this as rows they have to be clickable in order to recognize click events.
