Write this in your onBindViewHolder() of adapter class:
holder.setIsRecyclable(false);
I had the same issue and adding this code had helped me.
Edit:The issue is caused because when we scroll in Recycler View the cells gets recycled and in order to make sure the cells don't get recycled, the above method is used.

Looking at your code and comments I think you know how RecyclerView works especially re-using views.. The only thing you missed is setting view status on all scenarios, what I mean is - you always need to write else part of code
class MyViewHolder extends RecyclerView.ViewHolder {
RadioGroup vRadioGroup;
public MyViewHolder(View itemView) {
super(itemView);
vRadioGroup = (RadioGroup) itemView.findViewById(R.id.group1);
//your other stuff
vRadioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup radioGroup, int i) {
int clickedPos= (int) radioGroup.getTag();
messageArrayList.get(clickedPos).setSelectedRadioButtonId(radioButtonID);
}
});
}
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
Message message = messageArrayList.get(position);
//your other stuff
holder.vRadioGroup.setTag(position);
if (message.getSelectedRadioButtonId()!= -1){
holder.vRadioGroup.check(message.getSelectedRadioButtonId());
}else{
//your always need to write else condition
holder.vRadioGroup.clearCheck();
}
}
hope this helps..

Check Box selected is displayed wrongly

I am working on a screen where i am populating a list view using base adapter.Each row of list view contains a circular image view,Text View and Check box .On clicking single tick on toolbar ,i am displaying the id of user corresponding to checked button But it is displayed wrongly.I am implementing the following screen:
1.Bean_Friends
public class Bean_Friends {
private String name, url, extension, friendsID;
private String friendSelected = "false";
public String getName() {

this.friendsID = friendsID;
}
public String getFriendSelected() {
return friendSelected;
}
public void setFriendSelected(String friendSelected) {
this.friendSelected = friendSelected;
}
}
2.Adapter_Friends_Group.java

}
}
}
Updated code:

ViewHolder viewHolder = null;
if (inflater == null) {
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
if (view == null) {
view = inflater.inflate(R.layout.feed_item_friends, null);

//Setting name in the textview
viewHolder.txtName.setText(name);
//Setting boolean isSelected if the Checkbox is checked
viewHolder.chkFriend.setChecked(bean_friends.isSelected());
viewHolder.chkFriend.setTag(bean_friends);
viewHolder.chkFriend.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
CheckBox cb = (CheckBox) view;
Bean_Friends bean_friends = (Bean_Friends) cb.getTag();
Toast.makeText(context, "Clicked on Checkbox: " + bean_friends.getName() + " is " + cb.isChecked(), Toast.LENGTH_LONG).show();
bean_friends.setIsSelected(cb.isChecked());
}
});
return view;
}
}
Bean
public class Bean_Friends {
private String name, url, extension, friendsID;

return name;
}
public void setName(String name) {
this.name = name;
}

}

}
public String getFriendsID() {
return friendsID;
}
public void setFriendsID(String friendsID) {
this.friendsID = friendsID;
}
public boolean isSelected() {
return isSelected;
}
public void setIsSelected(boolean isSelected) {
this.isSelected = isSelected;
}
}
Method inside Activity
public void createNewGroup() {
StringBuffer responseText = new StringBuffer();
listBeanFriends = adapter_friends_group.listBeanFriends;
// Log.e("Size of adapter_friends", String.valueOf(adapter_friends_group.listBeanFriends.size()));
Log.e("Size of listbeanFriends", String.valueOf(listBeanFriends.size()));
for (int i = 0; i < listBeanFriends.size(); i++) {
Log.e("Loop Working", String.valueOf(i));
Bean_Friends bean_friends = listBeanFriends.get(i);
String friendID = bean_friends.getFriendsID();
String friendName = bean_friends.getName();
Log.e("FriendsName", friendName);
Log.e("FriendID", friendID);
Log.e("FriendSelected", String.valueOf(bean_friends.isSelected()));
if (bean_friends.isSelected()) {
responseText.append("\n" + bean_friends.getName() + " " + bean_friends.getFriendsID());
}
}
Toast.makeText(NewGroupActivity.this, responseText, Toast.LENGTH_SHORT).show();
}

I think the mistake is in this line :-
//If check box is checked,then add true to bean else add false to bean
if (chkFriends.isChecked()) {
bean_friends.setFriendSelected("true");
} else {
bean_friends.setFriendSelected("false");
}
Here you are setting 'setFriendSelected' based on whether the chkFriends is checked or not. In list View the views are reused and if say you have checked 'A' as friend and then you scrolls down then the view of 'A' maybe reused in 'C' and by this code 'C' now will be checked as friend. Here you instead want to inflate your checkBox view according to whether 'C' is your friend or not. Try this instead:-
//If check box is checked,then add true to bean else add false to bean
if (bean_friends.getFriendSelected().equals("true")) {
chkFriends.setChecked(true);
} else {
chkFriends.setChecked(false);
}
P.S : you can use view holder pattern here for better performance.

ANDROID - Save images from ImageView to database

I made an app and so far i stored captured images in database. Then I split them in categories and showed them in different GridViews for each category. I managed to show them in differents ImageViews after i choose an image from each gridView. Now i was trying to take those choosen images and save them in database and then show them in ListView. The problem is that in the list there is nothing. I suppose that my mistake is in the part of the code that i am taking the images to save them.
Any help?
#Override

for (Outfits o : outfits) {
String record = "ID=" + o.getID() + " | Category=" + o.getImage1() + " | " + o.getImage2();
Log.d("Record", record);
}
}
}

The issue is in Database.class you are missing a line check this out
public List<Outfits> readAllOutfits(){
SQLiteDatabase db = this.getWritableDatabase();
List<Outfits> outfits = new ArrayList<Outfits>();
Cursor cursor = db.query(SQLITE_TABLE_2, columns_2, null, null, null, null, null);
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
Outfits out = new Outfits();
out.setID(Integer.parseInt(cursor.getString(0)));
out.setImage1(cursor.getString(1));
out.setImage2(cursor.getString(2));
out.setImage3(cursor.getString(3));
out.setImage4(cursor.getString(4));
out.setImage5(cursor.getString(5));
out.setImage6(cursor.getString(6));
outfits.add(out);//this is the line you missed
cursor.moveToNext();
}
cursor.close();
return outfits;
}
hope it works

ListView with different layouts with two different objects

I want to populate a ListView with different layouts for odd and even rows. It should look like this:
I use two objects "OddListItem" and "EvenListItem" to store/access the data. I do not know how to pass both objects to my custom listview adapter and get the correct view.
My object classes:
public class OddListItem {
private String time_start;
private String time_end;
private String location;
public OddListItem(String time_start, String time_end, String location) {
super();
this.time_start = time_start;
this.time_end = time_end;
this.location = location;
}
// getters and setters
void setTimeStart(String time_start) {
this.time_start = time_start;
}
void setTimeEnd(String time_end) {
this.time_end = time_end;
}
void setLocation(String location) {
this.location = location;
}
public String getTimeStart() {
return time_start;
}
public String getTimeEnd() {
return time_end;
}
public String getLocation() {
return location;
}
}
public class EvenListItem {
private String image;
private String location;
public EvenListItem (String image, String location) {
super();
this.image = image;
this.location = location;
}
// getters and setters
void setImage(String image) {
this.image = image;
}
void setLocation(String location) {
this.location = location;
}
public String getImage() {
return image;
}
public String getLocation() {
return location;
}
}
MyCustomAdapter:
public class MyCustomAdapter extends BaseAdapter {
// Tag for Logging
private static final String TAG = "MyCustomAdapter";
int type;
private static final int TYPE_ITEM = 0;
private static final int TYPE_SEPARATOR = 1;
private static final int TYPE_MAX_COUNT = TYPE_SEPARATOR + 1;
private ArrayList<OddListItem> mData = new ArrayList<OddListItem>();
private LayoutInflater mInflater;
//private TreeSet mSeparatorsSet = new TreeSet();
private Context context;
public MyCustomAdapter(Context context) {
mInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.context = context;
}
public void addItem(final OddListItem item) {
mData.add(item);
//The notification is not necessary since the items are not added dynamically
//notifyDataSetChanged();
}
public void addSeparatorItem(final OddListItem item) {
mData.add(item);
//The notification is not necessary since the items are not added dynamically
//notifyDataSetChanged();
}
#Override
public int getItemViewType(int position) {
/*if ((position%2) == 0){
type = TYPE_ITEM;
} else {
type = TYPE_SEPARATOR;
}
return type;*/
return position%2;
}
#Override
public int getViewTypeCount() {
return TYPE_MAX_COUNT;
}
#Override
public int getCount() {
return mData.size();
}
#Override
public OddListItem 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) {
ViewHolder holder = null;
int type = getItemViewType(position);
Log.d(TAG, "getView " + position + " " + convertView + " type = " + type);
if (convertView == null) {
holder = new ViewHolder();
switch (type) {
case TYPE_ITEM:
//inflate the new layout
convertView = mInflater.inflate(R.layout.detail_list_row_odd, parent, false);
holder.tv_time_from = (TextView) convertView.findViewById(R.id.tv_time_from);
holder.tv_time_to = (TextView) convertView.findViewById(R.id.tv_time_to);
holder.tv_current_location_odd = (TextView) convertView.findViewById(R.id.tv_current_location_odd);
//fill the layout with values
/*holder.tv_time_from.setText("12:34");
holder.tv_time_to.setText("12:37");
holder.tv_current_location_odd.setText("Aktueller Standort");*/
holder.tv_time_from.setText(mData.get(position).getTimeStart());
holder.tv_time_to.setText(mData.get(position).getTimeEnd());
holder.tv_current_location_odd.setText(mData.get(position).getLocation());
break;
case TYPE_SEPARATOR:
//inflate the new layout
convertView = mInflater.inflate(R.layout.detail_list_row_even, parent, false);
holder.tv_current_location_even = (TextView) convertView.findViewById(R.id.tv_current_location_even);
holder.img_transport = (ImageView) convertView.findViewById(R.id.img_transport);
//fill the layout with values
holder.tv_current_location_even.setText("Hauptbahnhof");
holder.img_transport.setImageDrawable(context.getResources().getDrawable(R.drawable.rollator));
break;
default:
break;
}
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
return convertView;
}
private static class ViewHolder {
public TextView tv_time_from;
public TextView tv_time_to;
public TextView tv_current_location_odd;
public TextView tv_current_location_even;
public ImageView img_transport;
}
}
Here I generate the data and call the adapter:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detailed_connection);
generateData();
//fill ListView with custom content from MyCustomAdapter class
mAdapter = new MyCustomAdapter(getApplicationContext());
for (int i = 1; i < odd_items.size(); i++) {
mAdapter.addItem(odd_items.get(i));
if (i % 1 == 0) {
mAdapter.addSeparatorItem(odd_items.get(i));
}
}
setListAdapter(mAdapter);
//set duration text
tv_duration = (TextView)findViewById(R.id.tv_duration);
tv_duration.setText("Dauer: 22 Minuten");
}
private void generateData() {
odd_items = new ArrayList<OddListItem>();
odd_items.add(new OddListItem("12:34", "", "Aktueller Standort"));
odd_items.add(new OddListItem("12:37", "12:37", "TUM"));
odd_items.add(new OddListItem("12:42", "12:42", "Hauptbahnhof Nord"));
odd_items.add(new OddListItem("12:48", "12:48", "Hauptbahnhof"));
even_items = new ArrayList<EvenListItem>();
even_items.add(new EvenListItem("R.drawable.rollator", "3 Minuten Fußweg"));
even_items.add(new EvenListItem("R.drawable.bus", "Richtung Hauptbahnhof Nord"));
even_items.add(new EvenListItem("R.drawable.rollator", "6 Minuten Fußweg"));
mData = new Data(odd_items, even_items);
}
Any help would be great. Maybe there is also a better approach then please let me know.

I would create a Single list of Items
public class Items {
private String time_start;
private String time_end;
private String location;
private int image;
private String locationeven;
private int oddoreven;
public String getTime_start() {
return time_start;
}
public void setTime_start(String time_start) {
this.time_start = time_start;
}
public String getTime_end() {
return time_end;
}
public void setTime_end(String time_end) {
this.time_end = time_end;
}
public String getLocation() {
return location;
}
public void setLocation(String location) {
this.location = location;
}
public int getImage() {
return image;
}
public void setImage(int image) {
this.image = image;
}
public String getLocationeven() {
return locationeven;
}
public void setLocationeven(String locationeven) {
this.locationeven = locationeven;
}
public int getOddoreven() {
return oddoreven;
}
public void setOddoreven(int oddoreven) {
this.oddoreven = oddoreven;
}
}
In onCreate of Activity call
generateData() ;
Then
ArrayList<Items> oddorevenlist = new ArrayList<Items>();
private void generateData() {
Items item1 = new Items();
item1.setTime_start("12:34");
item1.setTime_end("");
item1.setLocation("Aktueller Standort");
item1.setOddoreven(0);
oddorevenlist.add(item1);
Items item2 = new Items();
item2.setImage(R.drawable.ic_launcher);
item2.setLocationeven("3 Minuten Fußweg");
item2.setOddoreven(1);
oddorevenlist.add(item2);
Items item3 = new Items();
item3.setTime_start("12:37");
item3.setTime_end("12:37");
item3.setLocation("Tum");
item3.setOddoreven(0);
oddorevenlist.add(item3);
Items item4 = new Items();
item4.setImage(R.drawable.ic_launcher);
item4.setLocationeven("Richtung Hauptbahnhof Nord");
item4.setOddoreven(1);
oddorevenlist.add(item4);
Items item5 = new Items();
item5.setTime_start("12:42");
item5.setTime_end("12:42");
item5.setLocation("Hauptbahnhof Nord");
item5.setOddoreven(0);
oddorevenlist.add(item5);
Items item6 = new Items();
item6.setImage(R.drawable.ic_launcher);
item6.setLocationeven("R6 Minuten Fußweg");
item6.setOddoreven(1);
oddorevenlist.add(item6);
Items item7 = new Items();
item7.setTime_start("12:48");
item7.setTime_end("12:48");
item7.setLocation("HHauptbahnhof");
item7.setOddoreven(0);
oddorevenlist.add(item7);
MyCustomAdapter mAdapter = new MyCustomAdapter(this,oddorevenlist);
setListAdapter(mAdapter);
}
