I'm trying to create a listview with different items within it. I want to use a switch statement to do this but I'm struggling to produce this I have created this with one XML layout how can I use multiple XML Layouts. I've attached my code - thank you in advance!
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_postlist);
this.generateDummyData();
ListView listView = (ListView) this.findViewById(R.id.postListView);
final PostItemAdapter itemAdapter = new PostItemAdapter(getApplicationContext(), this.generateDummyData());
listView.setAdapter(itemAdapter);
}
private ArrayList<PostData> generateDummyData() {
PostData data = null;
ArrayList<PostData> listData = new ArrayList<PostData>();
for (int i = 0; i < 20; i++) {
data = new PostData();
data.postTitle = "Person " + (i + 1)
+ " Name Surname";
data.postThumbUrl = null;
listData.add(data);
}
return listData;
}
// Get dummy data for Activity Feed
class PostDataTask extends AsyncTask<Integer, Void, Void> {
ArrayList<PostData> recentTracks;
#Override
protected Void doInBackground(Integer... page) {
try {
// Get a page of 15 tracks
// Simplified - getPage accepts 'page' and 'limit' parameters and returns a Collection<Track>
recentTracks = new ArrayList<PostData>();
Thread.sleep(3000);
PostData data = null;
for (int i = 0; i < 10; i++) {
data = new PostData();
data.postTitle = "Person " + (i + 1)
+ " Name is the Post Title from RSS Feed";
data.postThumbUrl = null;
recentTracks.add(data);
}
} catch (Exception e) {

return null;
}

listView.setAdapter(adapter);

adapter.notifyDataSetChanged();
}
}
}
public class PostItemAdapter extends ArrayAdapter<PostData> {
private final Context context;
private final ArrayList<PostData> items;

public PostItemAdapter(Context context, ArrayList<PostData> recentTrackArrayList) {

At first use ViewHolder pattern.
At second make interfase of Item which will include two methods:
getType() - which return the type of your item;
getView(LayoutInflater inflater, View convertView) - which return the view of row. Inside this method create ViewHolder instance, then inflate View parameter to VH and do some action with result view.
. Then create 2 (or how much u need) classes which would implement Item. Define methods. Then in ListAdapter in getView() call getView() of items and return it to list.
Using the view holder pattern won't work if your items are completely different.
For every item, you need to check what kind of item you want to display and inflate a different view depending on it (for example, using a switch as you said)

I'm trying to get data using retrofit2 and display those data using a list passing through as a parameter of Custom adapter. When I store data in a List in onResponse() method, in onResponse() method list have some value. But in oncreate() method its give me null. Though, I declared List as global. When I run the app sometimes its display nothing and sometimes app get crash. I know it's sounds like crazy. But it's happen. so, I want to know, what's wrong with my Code? how can I display data in listview?
Forgive me if something wrong with my question pattern yet this my maiden question at this site.

It's perfectly normal that it dosent work.
putting your method getInvistigation() before the loop does not mean that the response of your request was done
Calling a webservice creates another thread that waits for the server to send the response, sometimes the response takes time depends from the server and the latency of your internet connection.
you simply need to place the treatment (the loop and adapter) inside getInvistagion after getting the data.
I got a list, that i would like to show in a ListView, using my own custom adapter. So this list have some null values in it, and also some "important" not-null values.
It could be like this:
(N representing Null)
(D representint some valuable data)
myList:
[N,N,D,D,N,N,D,N,D,N,N] for example.
So i got my adapter, but i cannot handle the null values in the list.
This is my adapter:
public class ItemAdapter extends ArrayAdapter {
List<Item> itemList;
private Activity act;
boolean selling;
public ItemAdapter(Activity act, List<Item> itemList, boolean selling) {
super(act, R.layout.item_view_layout, itemList);
this.itemList = itemList;
this.act = act;
this.selling = selling;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
final Item itemManipulated = itemList.get(position);
if (convertView == null) {
convertView = new ItemInShopView(act, itemManipulated);
holder = new ViewHolder();
holder.convertView = convertView;
holder.itemNameTextView = (TextView) ((ItemView) convertView).getItemNameTextView();
holder.iconImageView = (ImageView) ((ItemView) convertView).getItemIconImageView();
holder.coinView = (CoinView) ((ItemInShopView) convertView).getCoinView();
holder.coinView.init(act);
holder.itemRarityHidedTextView = (TextView) ((ItemView) convertView).getItemRarityHidedTextView();
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.itemNameTextView.setText(itemManipulated.getName());
holder.iconImageView.setImageResource(itemManipulated.getIcon());
holder.itemRarityHidedTextView.setText(itemManipulated.getRarity());
Colorer.setTextViewColorByItemRarity(holder.itemNameTextView, holder.getRarity(), act);
if (selling) {
holder.coinView.setCoins(itemManipulated.getSellPrice());
} else {
holder.coinView.setCoins(itemManipulated.getPrice());
}
holder.convertView.setOnClickListener(new OnClickListenerWithPreventDoubleTapper(itemManipulated));
holder.convertView.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
return false;
}
});
return convertView;
}
class OnClickListenerWithPreventDoubleTapper extends OnClickListenerWithPreventDoubleTap {
Item item;
public OnClickListenerWithPreventDoubleTapper(Item item) {
this.item = item;
}
#Override
protected void performAction() {
new ItemDialog(act, item).show();
}
}
static class ViewHolder {
TextView itemRarityHidedTextView;
TextView itemNameTextView;
ImageView iconImageView;
CoinView coinView;
View convertView;
public String getRarity() {
return itemRarityHidedTextView.getText().toString();
}
}
}
How could i implement some way to get the adapter handle null values and shows nothing there, or maybe show a dummy layout with nothing on it?
I couldnt make a new list without null values and pass these new list to the adapter, because the nulls have an important meaning in an other view.
I hope my problem is clear. Please help if you can.
Why not just?
if (itemManipulated != null){
holder.itemNameTextView.setText(itemManipulated.getName());
holder.iconImageView.setImageResource(itemManipulated.getIcon());
holder.itemRarityHidedTextView.setText(itemManipulated.getRarity());
Colorer.setTextViewColorByItemRarity(holder.itemNameTextView, holder.getRarity(),act);
if (selling) {
holder.coinView.setCoins(itemManipulated.getSellPrice());
} else {
holder.coinView.setCoins(itemManipulated.getPrice());
}
} else {
holder.itemNameTextView.setText("No Item");
... (whatever default values you like)
}
Edit:
If you don't want to display nulls at all you will need to do something more complex.
in getView: find the nth piece of actual data
in getCount: return the number of pieces of actual data
getView:
int posInArray = -1;
for (int i =0; i <= position; i++){
posInArray++;
while(itemList.get(posInArray) == null){
posInArray++;
}
}
itemManipulated = itemList.get(posInArray);
...
getCount:
int count = 0;
for(int i = 0; i < itemList.size(); i++){
if (itemList.get(i) != null){
count++;
}
}
return count;
I'm new to android. I'm trying to get my list view to update, I've tried everything...from calling notifydatasetchanged on the ui thread to just simply recreating my list adapter but for whatever reason when I update, no matter which method I use I have to scroll to see the changes. By this I mean that the data updates (say 13:01 changes to 13:02 in the list), it will update, but to see the change I have to scroll so that 13:01 goes off screen and then move back and it will have updated visually.
Why is this? (I can't post code right now as I'm on my phone but if required I will post later.)
EDIT: Here's the relevant code...sorry it took so long I haven't been at my computer for a couple of days.

did you try to update your list using the adapter?
dataadapter.clear();
dataadapter.addAll(allDataResult);
To show and update content in a ListView you should:
Create or find your ListView
Create your ListAdapter
Add your ListAdapter to your ListView
Add data to your ListAdapter
Call notifyDataSetChanged() on your ListAdapter.
Example:
ListView listView = (ListView) findViewById(R.id.listview);
MyListAdapter myListAdapter = new MyListAdapter();
listView.setAdapter(myListAdapter);
myListAdapter.add("Hello");
myListAdapter.add("Hi");
myListAdapter.notifyDataSetChanged();
Note: if you're using a subclass of ArrayAdapter the notifyDataSetChanged() will be called for you when you use the methods add(), addAll(), etc.
I'm using ListView to show search results. I have a Coustomized arrayListAdapter which returns a list of Objects. This is working fine. My listView is showing just a TextView nothing else.
But I want to clear the List when I again go to the search page. I have tried
#Override
protected void onResume()
{
mListAdapter.clear();
mListAdapter.notifyDataSetChanged();
super.onResume();
}
And the SearchListAdapter
public class SearchListAdapter extends ArrayAdapter<Chapter>
{
public Context context;
private static String searchText = null;
public SearchListAdapter(Context context)
{
super(context, R.layout.favorite_tab_list_view_row);
this.context = context;
}
#Override
public void clear()
{
for (int i = 0; i < getCount(); i++)
getSearchChapters().remove(i);
notifyDataSetChanged();
super.clear();
}
private ArrayList<Chapter> getSearchChapters()
{
ArrayList<Chapter> chapter = new ArrayList<Chapter>();
if (searchText != null)
for (int i = 0; i < DataStore.getHierarchicalChapters()
.getSubChapters().size(); i++)
{
String str = DataStore.getHierarchicalChapters()
.getSubChapters().get(i).getChapterContent()
.toLowerCase();
Pattern pat = Pattern.compile(searchText.toLowerCase());
Matcher mat = pat.matcher(str);
while (mat.find())
{mat.start()); //
chapter.add(DataStore.getHierarchicalChapters()
.getSubChapters().get(i)); // the
break;
// occurrance
}
if (DataStore.getHierarchicalChapters().getSubChapters().get(i)
.hasSubchapters())
{
for (int j = 0; j < DataStore.getHierarchicalChapters()
.getSubChapters().get(i).getSubChapters().size(); j++)
{
str = DataStore.getHierarchicalChapters()
.getSubChapters().get(i).getSubChapters()
.get(j).getChapterContent();
mat = pat.matcher(str);
while (mat.find())
{
chapter.add(DataStore.getHierarchicalChapters()
.getSubChapters().get(i).getSubChapters()
.get(j));
break;
}
}
}
}
return chapter;
}
#Override
public int getCount()
{
return getSearchChapters().size();
}
#Override
public Chapter getItem(int position)
{
return getSearchChapters().get(position);
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
View row = convertView;
if (row == null)
{
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.favorite_tab_list_view_row, parent,
false);
ViewHolder viewHolder = new ViewHolder();
viewHolder.chapterName = (TextView) row
.findViewById(R.id.favoriteChapterTextViewId);
row.setTag(viewHolder);
}
ViewHolder viewHolder = (ViewHolder) row.getTag();
viewHolder.chapterName.setText(getSearchChapters().get(position)
.getTitle());
return row;
}
static class ViewHolder
{
public TextView chapterName;
}
public static void setSearchText(String searchText)
{
SearchListAdapter.searchText = searchText;
}
}
My question is, How can I clear the list ?
Thank You.
I think you have to override the method clear() for your custom ArrayAdapter and manually empty the list of objects on which your adapter is based(and don't forget to call notifyDataSetChanged()). This is what the default ArrayAdapter is doing.
EDIT :
Your code will never work now because your custom adapter gets its data from calling the method private ArrayList<Chapter> getSearchChapters() which rebuilds the adapter's data every time the method is called(for example every time the adapter calls getView() it will rebuild the data). My advice is to make a private field in your adapter :
ArrayList<Chapter> data;
and then in your adapter's constructor initialize it by calling the method getSearchChapters() :
data = getSearchChapters();
Then you can override the method clear():
#Override
public void clear() {
data.clear();
notifyDataSetChanged();
super.clear();
}
Also you can't call clear from onResume() because your list will never get populated with data(the adapter will be empty). I didn't understand when you want to clear the list so i can't tell you when to call the adapter.clear(). You can make a test with a button that calls clear() to see if this clears the adapter.
Clear the ArrayList that the Adapter is using then call notifyDataSetChanged() on Adapter
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.
