To avoid the unexpected behaviour , provide the implementations of
#Override
public Object getItem(int position) {
return mProducts.get(position);
}
#Override
public long getItemId(int position) {
//return position; or better to provide some unique id
// as there is one in your code, product id
return mProducts.get(position).prod_id;
}
Note : remove notifyDataSetChanged(); in getView because it will trigger the adapter to refresh all view while they are under creating which can cause this behaviour.

What is the intent of the methods getItem and getItemId in the Android class BaseAdapter?

Android : Unable to delete ListView item from menu

I am new here so please bear with my naivety. I am working on a music player that will display a menu on clicking 'dots' buttton(given in code below) in listview item. Inside the menu there will be a button to delete. The listview is getting populated by a custom adapter. Here is the code of adapter...
private class hashmapAdapter extends BaseAdapter implements Filterable {
HashMap<Integer, NowPlayingActivity.Details> NewDetails = new HashMap<>();
private hashmapAdapter(HashMap<Integer, NowPlayingActivity.Details> hashMap) {
if(NewDetails.size()==0) {
NewDetails.putAll(hashMap);
}
}
#Override
public int getCount() {
return NewDetails.size();
}
#Override
public Object getItem(int position) {
return NewDetails.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final View result;
if(convertView == null) {
result = LayoutInflater.from(parent.getContext()).inflate(R.layout.single_item,parent,false);
} else {
result = convertView;
}
((TextView)result.findViewById(R.id.Name)).setText(NewDetails.get(position).getName());
((TextView)result.findViewById(R.id.artist)).setText(NewDetails.get(position).getArtist());
((TextView)result.findViewById(R.id.duration)).setText(NewDetails.get(position).getDuration()+" || ");
dots = (Button)result.findViewById(R.id.dots);
dots.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
name = (TextView)result.findViewById(R.id.Name);
LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
View popup_view = inflater.inflate(R.layout.option_layout,null);
RelativeLayout item = (RelativeLayout) popup_view.findViewById(R.id.popup);
final float width= (getResources().getDimension(R.dimen.width_entry_in_dp));
final float height= getResources().getDimension(R.dimen.height_entry_in_dp);
final PopupWindow popupWindow = new PopupWindow(popup_view,Math.round(width),Math.round(height),true);
popupWindow.showAtLocation(item, Gravity.END, 0, 0);
popupWindow.showAsDropDown(dots);
play_next_btn = (Button)popup_view.findViewById(R.id.play_next);
add_to_playlist = (Button)popup_view.findViewById(R.id.add_to_playlist);
share = (Button)popup_view.findViewById(R.id.share);
delete = (Button)popup_view.findViewById(R.id.delete);
delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for(int i=0;i<NewDetails.size();i++) {
if(NewDetails.get(i).getName().equals(name.getText().toString())) {
for(int j=0;j<hashMap.size();j++) {
if(hashMap.get(j).getName().equals(name.getText().toString())) {
if (true) {
NewDetails.remove(i);
hashMap.remove(j);
}
}
}
}
}
populate1(NewDetails);
popupWindow.dismiss();
}
});
}
});
return result;}
Now the problem is that after deleting element when i call populate1(NewDetails), it gives a null pointer exception on NewDetails.get(position).getName(). So on repopulating listview i am getting NPE error. Following is the populate1() function code...
public void populate1(HashMap<Integer,NowPlayingActivity.Details> hashMap) {
adapter = new hashmapAdapter(hashMap);
library.setAdapter(adapter);
adapter.notifyDataSetChanged();
library.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
name = (TextView)view.findViewById(R.id.Name);
String SongName = name.getText().toString();
Intent intent = new Intent(getApplicationContext(),NowPlayingActivity.class);
intent.putExtra("SongName",SongName);
setResult(555,intent);
finish();
}
});
}
I have already tried notifydatasetchanged() and listview.invalidateviews(), both didnt work. File is getting deleted but the adapter is not refreshing the list to remove element. Here is the xml layout of single_item for listview....`

issue is:

holder.ll_unavail.setVisibility(View.GONE);
}else {
holder.ll_unavail.setVisibility(View.VISIBLE);
holder.ll_add.setVisibility(View.GONE);
}
in this loop the next item visibility get changes..

use this condition and check
if (model.getInStock().matches("In Stock")) {
holder.ll_add.setVisibility(View.VISIBLE);
holder.ll_unavail.setVisibility(View.GONE);
}else {
holder.ll_unavail.setVisibility(View.VISIBLE);
holder.ll_add.setVisibility(View.GONE);
}

The height of ExpandableListView impacts the display of ChildView

Here's the behavior: when clicking the group header, no child view is displayed. From LogCat, I can see that getViewGroup() in the adapter is called twice though, but getChildView() is not called at all. After searching the internet and trying them out, I still can't get the child view displayed when clicking on the group header, but when I tried setting the ExpanandableListView height with a fix height, say, 400dp, like this:
<ExpandableListView xmlns:
android:layout_width="match_parent"
android:layout_height="400dp"
android:id="#+id/expLVClaims"/>
the child view is then expanded and collapsed as expected. But the thing is that because the fixed height will makes the ExpandableListView occupy 400dp space vertically, even no data is in the adapter at all, which is unwanted behavior.
Can someone throw some hints?
Thanks in advance!

First thing:
You should not use any scrolling component like expandable list, inside a scroll view here's why Listview inside ScrollView is not scrolling on Android.
Second thing:
Height of ExpandableListView should be match_parent.
I was also facing the same problem related to height, and making ExpandableListView height as match_parent resolved my problem. I think this will help you.

How can I change the icon of a button in android gridView row?

I want to change the button of android grid view row item, when I click in the first row, I can change the button (play) to (pause), then when I go to another row, also I can change the play to pause, but I need to change the previous row automatically to pause, because it is now still play.
I have tried the code below but not effect.

}
});
return convertView;
}
StopPlayer and change previous icon
public void stopPlayer(Context c, int current, int previous) {
System.out.println("current : " + current);
System.out.println("previous : " + previous);
if (mp != null && mp.isPlaying()) {
mp.stop();
}
if (current!=previous){
View v= this.getView(previousPosition, null, null);
Button b = (Button) v.findViewById(R.id.buttonPlay);
b.setBackground(c.getResources().getDrawable(R.drawable.ic_action_play));
this.notifyDataSetChanged();
mGridview.refreshDrawableState();
}
}

Instead of doing this
View v= this.getView(previousPosition, null, null);
change your drawable on item click method
mGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Button b = (Button) view.findViewById(R.id.buttonPlay);
b.setBackground(c.getResources().getDrawable(R.drawable.ic_action_play));
your_adapter.notifyDataSetChanged();
}
});
I think , this will work for you :)

I think of you question as a partial refresh one. We all run into partial refresh problem when dealing with ListView or GridView. As for your case, partial refresh may be like this:
private void refreshPartially(int position){
int firstVisiblePosition = listview.getFirstVisiblePosition();
int lastVisiblePosition = listview.getLastVisiblePosition();
if(position>=firstVisiblePosition && position<=lastVisiblePosition){
View view = listview.getChildAt(position - firstVisiblePosition);
if(view.getTag() instanceof ViewHolder){
ViewHolder vh = (ViewHolder)view.getTag();
//holder.play.setBackgroundResource(resId);//Do something here.
...
}
}
}
