This is because of object reuse in your list view.
You can manage separate ArrayList or HashMap to maintain your likes.
And based on that you should update in your getView like this,
if([already selected]) {
viewHolder.likebtn.setBackground([your selected drawable]);
} else {
viewHolder.likebtn.setBackground([your non selected drawable]);
}

In BaseAdapter setVisibility(View.GONE); is not hiding the view but space is released

In my BaseAdpater I'm setting the visibility of a view to GONE in a row after some operation. All operation is fine but view remains visible in background while lower views are move up until i touch the screen. It means listview is updating the views and releasing the space on setting visibility to GONE but view is still visible in background. What could be the issue?

if you mean after setting visiblity gone of a row, that row remains blank and that gap is visible,the better way is to filter the adapter content by using getFilter() to display by excluding that row content and notifyadapter changed.

Change this line
holder.wish_list.setImageResource(R.drawable.wishlist);
to this
Resources resources = getResources();
holder.wish_list.setImageDrawable(resources.getDrawable(R.drawable.wishlist));
and do the same in else part and check the output..
Note :
getResources().getDrawable is deprecated.
You can try ContextCompat.getDrawable:
holder.wish_list.setImageDrawable(ContextCompat.getDrawable(context,
R.drawable.wishlist));
UpDate :
check this way.

// here is default icon and set api value and send it

In Customized Gridview adapter, incorrect value is displayed while clicking an individual item

I used a customized Gridview adapter in application. It contains textview items in a particular order. When i click on individual textviews, it always shows a constant value. Here code follows
Main_activity.java
public class MainActivity extends Activity implements GridAdapter.ItemSelectedListener
{
private TextView tv;
private GridView gv;
private GridAdapter ga;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView)findViewById(R.id.TextMsg);
gv = (GridView)findViewById(R.id.gridView);
ga = new GridAdapter(this);
ga.setItemSelectedListener(this);
gv.setAdapter(ga);
GridAdapter.Item item = new GridAdapter.Item();
item.set("Header1", "Item1_1", "Item1_2", "Item1_3");
ga.add(item);
item = new GridAdapter.Item();
item.set("Header2", "Item2_1", "Item2_2", "Item2_3");
ga.add(item);
item = new GridAdapter.Item();

Above picture shows output of the screen. When i clicked on item1_1 or item2_1 or item3_1, it always shows item1_1.
How to solve this problem ?
thanks in advance

use getListview() in list Activity to get List..........
in Oncreate
ListView lv = getListView();
http://www.mkyong.com/android/android-listview-example/
this link has both ways
1- overriding onListItemClick(
2- Setting you listener..

Try this way..
ListView lv = getListView();
lv. storelist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
}
}
this are help you.
Thanks

Override the function onlistitemclick() for this. Here the integer position represents the postion of item that you had pressed
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
.......
}

Try this one
getListView().setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
// TODO Auto-generated method stub
}
});

Android VeiwFlow load images from SdCard

I'm using an implementation of ViewFlow example for my application where I have to swipe images from SdCard. With the code I'm using I can swipe images, but it's showing only one and i'm trying to set the whole images from my SdCard specific folder in the ViewFlow, but that's the problem that I have. I'm getting the path to the image by an ID which I get from sqlite database and depending on that I want to add these images to the view. So this is the code which I'm using for now :

}
And my ImageAdapter class :
package com.stampii.stampii.cards;
import java.util.ArrayList;
import com.stampii.stampii.R;
import android.content.Context;
import android.graphics.Bitmap;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
public class ImageAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<Bitmap> ids = new ArrayList<Bitmap>();
//private Bitmap bitmap;
public ImageAdapter(Context context, ArrayList<Bitmap> images) {
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ids = images;
}
#Override
public int getCount() {
return ids.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = mInflater.inflate(R.layout.image_item, null);
}
((ImageView) convertView.findViewById(R.id.imgView)).setImageBitmap(ids.get(position));
return convertView;
}
}
So my question is how can I add all images from my SdCard folder to this ViewFlow example when I had the path to these images. I've tried to load all of them, but in some cases the images are too much and it's throwing me an outofmemoryException, that's why I think it's better just to set the paths to them. So any help or suggestions are welcomed!
Thanks in advance!
Here is code of ViewFlow.class : ViewFlow

You can try something like this :
public class ImageAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<String> ids = new ArrayList<String>();
//private Bitmap bitmap;
public ImageAdapter(Context context, ArrayList<String> images) {
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ids = images;
}
#Override
public int getCount() {
return ids.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = mInflater.inflate(R.layout.image_item, null);
}
BitmapFactory.Options options = new BitmapFactory.Options();
options.inTempStorage = new byte[8*1024];
Bitmap ops = BitmapFactory.decodeFile(ids.get(position), options);
((ImageView) convertView.findViewById(R.id.imgView)).setImageBitmap(ops);
return convertView;
}
}
And :
public class Cards extends Activity {
public Cursor cursor;
int position;
int indexxx;
Bitmap b;
int objectId;
int cardsId;
ArrayList<Integer> ids;
String path;
int mediaType=5001;
ArrayList<String> images;
int card;
private ViewFlow viewFlow;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.circle_layout);
UserDatabaseHelper userDbHelper = new UserDatabaseHelper(this, null, 1);
userDbHelper.initialize(this);
//imgpaths = new ArrayList<HashMap<Integer, String>>();
HashMap<Integer, String> hm = new HashMap<Integer, String>();
ids = new ArrayList<Integer>();
images = new ArrayList<String>();
final int cardId = getIntent().getIntExtra("card_id",0);
Log.i("Card Id ","Card Id : "+cardId);
final int collId = getIntent().getIntExtra("collection_id",0);
Log.i("Collection Id ","Collection Id : "+collId);
position = getIntent().getIntExtra("position",0);
Log.i("position","position : "+position);
String cardSQL = "SELECT cm.cardId, cm.objectId "+
"FROM cardmedias AS cm "+
"INNER JOIN cards AS cd "+
"ON (cm.cardId = cd.objectId) "+
"WHERE cd.collectionId="+collId +" AND cm.mediaType="+mediaType;
Cursor cards = userDbHelper.executeSQLQuery(cardSQL);
if (cards.getCount() == 0) {
Log.i("", "No Image file");
cards.close();
} else if (cards.getCount() > 0) {
for (cards.move(0); cards.moveToNext(); cards.isAfterLast()) {
cardsId = Integer.parseInt(cards.getString(cards
.getColumnIndex("objectId")));
card = Integer.parseInt(cards.getString(cards
.getColumnIndex("cardId")));
String path = Environment.getExternalStorageDirectory()
+ "/.Stampii/MediaCard/" + cardsId + ".png";
ids.add(card);
hm.put(cardsId, path);
path = hm.get(cardsId);
Log.i("","path : "+hm.get(cardsId));
Log.i("","hm size : "+hm.size());
images.add(path);
}
}
Button back = (Button) findViewById(R.id.back_button);
back.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
});
viewFlow = (ViewFlow) findViewById(R.id.viewflow);
viewFlow.setAdapter(new ImageAdapter(this, images),position);
ImageButton prevBtn = (ImageButton) findViewById(R.id.previous_button);
prevBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
indexxx = viewFlow.getSelectedItemPosition()-1;
if (indexxx>=0) {
viewFlow.setAdapter(new ImageAdapter(Cards.this, images),indexxx);
viewFlow.setSelectedItemPosition(indexxx);
Log.i("indexxx", "indexxx : " + indexxx);
}
}
});
ImageButton nextBtn = (ImageButton) findViewById(R.id.next_button);
nextBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
indexxx = viewFlow.getSelectedItemPosition()+1;
if (indexxx<images.size()) {
viewFlow.setAdapter(new ImageAdapter(Cards.this, images),indexxx);
viewFlow.setSelectedItemPosition(indexxx);
Log.i("indexxx", "indexxx : " + indexxx);
}
}
});
Button info = (Button) findViewById(R.id.info_button);
info.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Cards.this, SingleCardInfo.class);
intent.putExtra("card_id", ids.get(position));
intent.putExtra("collection_id", collId);
startActivity(intent);
}
});
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
viewFlow.onConfigurationChanged(newConfig);
}
}
That should do the trick!
