Add two array list in same spinner with seperation in Android

I want to add two array list in the same spinner and when i click on spinner it should show two list separated with label, so that i can select item from any of the list in same spinner. how can i achieve this in android.
Currently i am doing like this, is it correct way to do this?
private void myFunction(){
ArrayList<String> arrayListOne = new ArrayList<>();
arrayListOne.add("LABEL NAME");
for (int i=0; i< 10; i++){
arrayListOne.add("name"+i);
}
ArrayList<String> arrayListTwo = new ArrayList<>();
arrayListTwo.add("LABEL DESIGNATION");
for (int i=0; i< 10; i++){
arrayListOne.add("designation"+i);
}
arrayListOne.addAll(arrayListTwo);
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<>(context, android.R.layout.simple_spinner_item, arrayListOne);
arrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinner.setAdapter(arrayAdapter);
}
Solution: So to achieve this I have created my own library Check this

For this question you need to create three arraylist which you can use according it:
ArrayList<String> arrayOne=new ArrayList<String>();
for(int i=0;i<=5;i++)
{
arrayOne.add(" "+i);
}
ArrayList<String> arrayTwo=new ArrayList<String>();
for(int j=0;j<=5;j++)
{
arrayTwo.add(" "+j);
}
after that you should merge both arraylist into one using this:
ArrayList<String> arrayFinal=new ArrayList<String>();
for(k=0;k<arrayOne.size();k++)
{
arrayFinal.add(arrayOne.get(k));
}
for(u=0;u<arrayTwo.size();u++)
{
arrayFinal.add(arrayTwo.get(u));
}
Now you can find a singal arraylist with merge two arraylist data, now you can initialize your spinner by final arraylist data.
make a custom adapter for where send the position of that place where you want to disable the label
using this:
public class CustomAdapter extends BaseAdapter {
List<String> ayylist;
Context context;
int postionDisable;
public CustomAdapter(Context context, List<String> ayylist,int postionDisable) {
this.ayylist = ayylist;
this.context = context;
this.postionDisable=postionDisable;
}
#Override
public int getCount() {
return ayylist.size();
}
#Override
public Object getItem(int position) {
return ayylist.get(position);
}
public boolean areAllItemsEnabled() {
return false;
}
public boolean isEnabled(int position) {
if (position == postionDisable) {
return false;
} else return true;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.simpletext1, parent, false);
TextView textView = (TextView) convertView.findViewById(R.id.TextView);
textView.setText(ayylist.get(position).toString());
textView.setBackgroundColor(context.getResources().getColor(R.color.whiteColor));
if (position == postionDisable) {
textView.setTextColor(context.getResources().getColor(R.color.blackcolor));
textView.setTextSize(15);
}
return convertView;
}
}

Custom spinner is not invoke custom listview?

I have a custom listview and spinner.First of all i am filling the listview and then i am clicking dropdown spinner.I am choosing a item(city).I want to update listview with new result.But whatever i can custom adapter getview is not call. So listview is not update. This is my screen
How can i do it?
I am filling spinner here
private void getCityListWithSpinner() {
cityListRequest = new CityListRequest(new AsyncListener() {
#Override

CinemaCitySelector2 citySelector = new CinemaCitySelector2();
cityList.add("Seçiniz");
for (int i = 0; i < cityArrayList.size(); i++) {
cityList.add(cityArrayList.get(i).getCinemaCity());
citySelector.CinemaCitySelector2(
CinemaCityMoviePickerActivity.this, ss, cityList,2);
}
}
CinemaCitySelector:
public class CinemaCitySelector2 implements OnItemSelectedListener {

return convertView;
}

I'd create a method to update the adapter once an item on your spinner is chosen:
cityspinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,int position, long id) {
city = (String) parent.getItemAtPosition(position);
resetCinema(city); //or onRestart();
}
public void onNothingSelected(AdapterView<?> parent){
}
});
And resetCinema(city) rechages the view depending on the city value. You can do this manually:
public void resetCinema(String city) {
//show list view elements depending on city
}
or just call a refresh of the whole Activity:
protected void onRestart() {
Intent refresh = new Intent(this, Main.class);
startActivity(refresh);//Start the same Activity
finish(); //finish Activity.
}

I suggest you to call
adapter2.notifyDataSetChange();
But anyway there is no need to initialize a new adapter every time.
you should create a method inside the adapter like this:
public void setMyArray(ArrayList<Cinema> items) {
myArray.clear();
myArray.addAll(items);
notifyDataSetChange();
}

Can't fill the listView?

I have a listview, and i start an intent to fill it. But the list shows up with a default image and no text. It is supposed to show up with different images and text.
I have two arrays, one is in string type and the other one is in drawable type... But my list doesn't show me none of these that i wanted...
My ListActivity:
public class fillLeftMenu extends ListActivity {
private View menu;
ImageView findLocation;
Spinner cityList;
ListView leftList;
String [] textIndex;
Drawable [] imageIndex;
ArrayList<LeftListItems> Left;
listAdapter lAdapter;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
dataTransfer dt = BonubonActivity.deneme;
menu = dt.getView();
findLocation = (ImageView) menu.findViewById(R.id.image_findLocation);
leftList = (ListView) menu.findViewById(R.id.list);
// add items to listView
Left = new ArrayList<LeftListItems>();
textIndex = new String[] {"Bugünün Fırsatları", "Son Dakika Bonusları", "Kadın", "Aile", "Çocuk", "Alışveriş", "Şehirden Kaçış", "Kışa Özel"};
imageIndex = new Drawable[] {leftList.getResources().getDrawable(R.drawable.kucukicon_01),leftList.getResources().getDrawable(R.drawable.kucukicon_02),leftList.getResources().getDrawable(R.drawable.kucukicon_03),leftList.getResources().getDrawable(R.drawable.kucukicon_04),leftList.getResources().getDrawable(R.drawable.kucukicon_05),leftList.getResources().getDrawable(R.drawable.kucukicon_06),leftList.getResources().getDrawable(R.drawable.kucukicon_07),leftList.getResources().getDrawable(R.drawable.kucukicon_08)};
lAdapter = new listAdapter(menu.getContext(), R.layout.list_item, Left);
leftList.setAdapter(lAdapter);
getIndex();
lAdapter.notifyDataSetChanged();
leftList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
}
});
finish();
}
private void getIndex() {
try{
LeftListItems item = new LeftListItems();
for(int i=0; i<textIndex.length; i++) {
item.setText(textIndex[i]);
item.setImage(imageIndex[i]);
Left.add(item);
lAdapter.add(Left.get(i));
}
}
catch (Exception e) {
Log.e("BACKGROUND_PROC", e.getMessage());
}
}
private class listAdapter extends ArrayAdapter<LeftListItems> {
private ArrayList<LeftListItems> items;
private Context ctx;
public listAdapter(Context ctx, int textViewResourceId, ArrayList<LeftListItems> items) {
super(ctx, textViewResourceId, items);
this.ctx = ctx;
this.items = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.list_item, null);
}
LeftListItems index = items.get(position);
if(index != null) {
TextView text = (TextView) v.findViewById(R.id.text);
ImageView img = (ImageView) v.findViewById(R.id.icon);
if(text != null)
text.setText(index.getText());
if(img != null)
img.setBackgroundDrawable(index.getImage());
}
return v;
}
}
}

Try calling getIndex() method before creating the adapter and setting it to the list. Like this:
getIndex();
//then create new adapter
lAdapter = new listAdapter(menu.getContext(), R.layout.list_item, Left);
leftList.setAdapter(lAdapter);

Display ListView TextView based on count acting strange

I have a ListView that is being populated with collection of items using a custom adapter. One of the properties of the collection is a count, and I have two TextViews in my ListView layout, one for the text and one for the count. I'd like not to display the count TextView if the count is zero. The code I have works fine when the ListView is initially loaded, but when I scroll the ListView, the count will show on random rows and constantly change if scroll the ListView up and down. This is the code I have:
public class Main extends ListActivity
{
private static CustomAdapter adapter = null;
#Override
public void onCreate(Bundle icicle)
{
List<Item> items = new ArrayList<Item>();
items = GetItems();
adapter = new CustomAdapter();
for (Item item : items)
adapter.addItem(item);
this.setListAdapter(adapter);
adapter.notifyDataSetChanged();
}
/* ADAPTER */
private class CustomAdapter extends BaseAdapter
{
private final List<Item> mData = new ArrayList<Item>();
private final LayoutInflater mInflater;
public CustomAdapter() {
mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void addItem(Item item) {
mData.add(item);
}
#Override
public int getCount() {
return mData.size();
}
#Override
public Object getItem(int position) {
return mData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
final ViewHolder holder;
final Item item = (Item)this.getItem(position);
if (convertView == null)
{
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.main, parent, false);
holder.text = (TextView)convertView.findViewById(R.id.text);
holder.count = (TextView)convertView.findViewById(R.id.count);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder)convertView.getTag();
}
holder.text.setText(item.getTitle());
if (item.getCount() > 0)
holder.count.setText(item.getCount().ToString());
else
holder.count.setVisibility(View.INVISIBLE);
return(convertView);
}
}
static class ViewHolder {
TextView text, count
}
Layout:
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
/>
<TextView
android:id="#+id/count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
/>
EDIT:
I was able to get it working by doing a hacky workaround. It seems setting the TextView's visibility to Invisible or Gone was causing the issue, so I just changed the color of the items with a zero count to the background color:
if (item.getCount() > 0)
holder.count.setText(item.getCount().ToString());
else
holder.count.setTextColor(Color.WHITE);
If anyone has a real fix, please let me know.

You should just do this:
if (item.getCount() > 0) {
holder.count.setText(item.getCount().ToString());
holder.count.setVisibility(View.VISIBLE);
}
else
holder.count.setVisibility(View.INVISIBLE);
Because you use a ViewHolder, you need to consider the fact that you might get an old View that's not showing the count. This means we need to make sure that the visibility of count is set to VISIBLE. Equally we want to hide it if the count is zero - so we change the visibility even though we might get a View that is all ready invisible.

I think you wrong a part of your code, Amend test this code:
if (item.getCount() > 0)
holder.count.setText(item.getCount());
else
holder.count.setVisibility(View.INVISIBLE);

Please go through this code you may helpful for the same.

Android: Do some action AFTER filling ListView elements

I have an activity with listview and attached footer. I created my custom adapter for filling ListView. After I filled it I need to do some actions.
This is my activity's code part:
public class MainActivity extends ListActivity {
final public String NO_USERS_IN_DB = "No users yet, please add some...";
DBAdapter db = new DBAdapter(this);
Activity activity = MainActivity.this;
private static final Pattern PATTERN = Pattern.compile(": *([^|]+)");
private static final int REQUEST_LOAD = 0;
boolean rewrite;
boolean userSelected = false;
final public int REQUEST_SAVE = 1;
boolean showAvatars;
boolean settingsGot = false;
int backgroundColor;
int titleColor;
int buttonBackgroundColor;
int buttonTextColor;
public class MyCustomAdapter extends ArrayAdapter<String> {
public MyCustomAdapter(Context context, int textViewResourceId,
String[] objects) {
super(context, textViewResourceId, objects);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
//return super.getView(position, convertView, parent);
if(!settingsGot){
getSettings();
settingsGot = true;
}
String[] users = getUsers();
LayoutInflater inflater=getLayoutInflater();
View row=inflater.inflate(R.layout.main, parent, false);
TextView label=(TextView)row.findViewById(R.id.label);
label.setText(users[position]);
if(showAvatars){
ImageView icon=(ImageView)row.findViewById(R.id.icon);
byte[] bb = getAvatar(users[position]);
if(bb != null && bb.length != 0){
icon.setImageBitmap(BitmapFactory.decodeByteArray(bb, 0, bb.length));
icon.setVisibility(View.VISIBLE);
}
}
return row;
}
}
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
db.open();
String[] users = db.getUsersList();
boolean showList = true;
if (users[0].equals("NOUSERSINTHEBASE")){
users[0] = NO_USERS_IN_DB;
}
if (showList){
View footer = getLayoutInflater().inflate(R.layout.footer, null);
ListView listView = getListView();
listView.addFooterView(footer);
this.setListAdapter(new MyCustomAdapter(this,
R.layout.main, users));
}else{
setContentView(R.layout.footer);
}
db.close();
}
So, method I need to do some actions after method getView done its work. Where should I place my doSomeMoreActionsAfterGetView() ?

After setListAdapter you can change it...
