ListView EditText values changing on Scrolling also Taking Duplicate Entry

ListView EditText values changing on Scrolling also Taking Duplicate Entry - android

Please Help to Solve My Issue !!
In the Activity there is a listview and A Button
ListView Row contains a TextView which displays the Serial No and 3 Edittexts (in which values will be entered)
The button Adds another row to the List.
I used my own class MemberEntry.
Problem is that In listview, data is entered smoothly but on scrolling
the textview value (Serial No.) remains fine but
the value of edittext (All 3) changes(The value of some other Edittext from the list takes place of another one).
I used this and found a little bit good results. But Not Accurate.
Code
Activity
OnCreate
MemberEntry m = new MemberEntry();
memberEntries = new ArrayList<>();
memberEntries.add(m);
adapter = new CustomListViewAdapter3(this, R.layout.row_entry_member, memberEntries);
LVMembers.setAdapter(adapter);
OnClick of a button
public void fab(View view) {
memberEntries.add(new MemberEntry());//memberEntries and adapter are global
adapter.notifyDataSetChanged();
}
Adapter

Focus on wrong edit text inside listview

When I try to click on EditText inside ListView item. It gains focus and loses focus, while debugging I found that if I clicked on 21st item, the position value changed like 21, 19, 1, 2 etc. Not sure if the list is re-rendering itself or something else is happening. I have already searched a lot and already tried configuring ListView (beforeDescendants and afterDescendants) and Activity (adjustPan).
I have used my custom adaptor. Sharing the XML file of ListView and list item along with java code of adapter.

Thanks in advance.

Insert this Line in onCreate before setContentView()
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_MASK_ADJUST);
It will definitely help you

Finally, I figured it out. the problem was trying to solve get tex changed value inside getview. This was re-rendering the list items and I was getting wrong focus and different weird behavious. I have created a textwatcher class and added it while initializing the object, so that it doesn't affect everytime for each item in the list. Below is the code for MyCustom Adapter
public class OrderViewListAdapter extends ArrayAdapter<OrderItemList> {
public OrderViewListAdapter(Context context, int resource) {
super(context, resource);
}

ImageButton minus;

MyCustomEditTextListener myCustomEditTextListener;
public ViewHolder(View convertView, MyCustomEditTextListener myCustomEditTextListener) {
this.myCustomEditTextListener = myCustomEditTextListener;
this.order_qty = (EditText) convertView.findViewById(R.id.number_of_item);
this.order_qty.addTextChangedListener(myCustomEditTextListener);
}
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// Get the data item for this position
OrderItemList vehicleTransit = mDataSet.get(position);
//System.out.println("kamal123" +mDataSet.get(position).getOrderID());
System.out.println("kamal123" +position);
ViewHolder viewHolder;
if (convertView == null) {
LayoutInflater inflater = LayoutInflater.from(getContext());
convertView = inflater.inflate(R.layout.list_item_selector, parent, false);
viewHolder = new ViewHolder(convertView, new MyCustomEditTextListener());
viewHolder.sku_desc = (TextView) convertView.findViewById(R.id
.item_name);
viewHolder.uom_desc = (TextView) convertView.findViewById(R.id
.uom_desc);
viewHolder.order_qty = (EditText) convertView.findViewById(R.id.number_of_item);
viewHolder.plus= (ImageButton)convertView.findViewById(R.id.button_plus) ;
viewHolder.minus= (ImageButton)convertView.findViewById(R.id.button_minus) ;
convertView.setTag(viewHolder);
viewHolder.plus.setTag(viewHolder);

} else {

Section Indexer does not show in listview

My Custom adapter is as follows:-
public class ListAdapter extends ArrayAdapter<Person> implements SectionIndexer {
private HashMap<String, Integer> alphaIndexer;
private String[] sections;
public ListAdapter(Context context, int textViewResourceId) {
super(context, textViewResourceId);
}
public ListAdapter(Context context, int resource, ArrayList<Person> items) {
super(context, resource, items);
alphaIndexer = new HashMap<String, Integer>();
for (int i = 0; i < items.size(); i++)
{
Log.d("State",items.get(i).getState().substring(0, 1).toUpperCase());
String s = items.get(i).getState().substring(0, 1).toUpperCase();
alphaIndexer.put(s, i);
}
Set<String> sectionLetters = alphaIndexer.keySet();
ArrayList<String> sectionList = new ArrayList<String>(sectionLetters);
Collections.sort(sectionList);
sections = new String[sectionList.size()];
sectionList.toArray(sections);
}
public int getPositionForSection(int section)
{
return alphaIndexer.get(sections[section]);
}
public int getSectionForPosition(int position)
{
return 1;
}
public Object[] getSections()
{
return sections;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {

if (v == null) {

vi = LayoutInflater.from(getContext());

}

if (p != null) {
ImageView im1= (ImageView) v.findViewById(R.id.legislator_image);
TextView tt1 = (TextView) v.findViewById(R.id.firstname);
TextView tt2 = (TextView) v.findViewById(R.id.details);
ImageView im2 = (ImageView) v.findViewById(R.id.getDetails);
if (im1 != null){
String url = p.getImage();
Picasso.with(getContext()).load(url).fit().centerCrop().into(im1);
}
if (tt1 != null) {
String name= p.getLastname()+", "+p.getFirstname();
tt1.setText(name);
}
if (tt2 != null) {
String details="";
if(p.getDistrict()!="NA")
details= "("+p.getParty()+")"+p.getState()+" - "+"District "+p.getDistrict();
else

}
I have implemented this custom adapter following a tutorial. I have implemented the section indexer. But the issue is that the section indexer does not show up in the app. I am trying to index stuff based on the first letter of each state of the person. I want the alphabetical list to show up in the list view so that when I tap on a particular letter it must show persons belonging to that state.

Please let me know if I am missing something. This is my first custom adapter so I may be doing something wrong.

Just use below structure ,Mayi know why youimplement sectionIndex
public class CustomeAdapter extends BaseAdapter {
#Override
public int getCount() {
return 0;
}
#Override
public Object getItem(int i) {
return null;
}
#Override
public long getItemId(int i) {
return 0;
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
return null;
}
}

Item missing from android grid view on scroll

I have grid view , on which each item consists of few images and text . When it loads for the first time , everything is fine but if I scroll to the bottom and the go back to top some two images are gone from a item , and it goes randomly .
here is the code for Grid view

Unable to select an item in a ListView whose content is set by an Array Adapter

I couldn't select an item on ListView. I use Custom Adapter to set content of ListView. I have set OnItemClickListener of ListView. However, it didn't respond. I appriciate your help. Here is my code:

this.connectionList.addAll(connList);
}
public void updateList(ArrayList<AbstractHolder> connList){
connectionList.clear();
connectionList.addAll(connList);
}
private class ViewHolder {
TextView name;
TextView acctype;
CheckBox sel;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {

Log.v("ConvertView", String.valueOf(position));
if (convertView == null) {
LayoutInflater vi = (LayoutInflater)(((Activity)this.getContext()).getSystemService(Context.LAYOUT_INFLATER_SERVICE));
convertView = vi.inflate(R.layout.connlist, null);
holder = new ViewHolder();
holder.name = (TextView) convertView.findViewById(R.id.connname);
holder.acctype = (TextView) convertView.findViewById(R.id.conntype);
holder.sel = (CheckBox) convertView.findViewById(R.id.checkBox1);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
}
AbstractHolder conn = connectionList.get(position);
holder.name.setText(conn.getName());
holder.acctype.setText(conn.getConntype());
holder.sel.setChecked(conn.isSelected());
holder.sel.setTag(conn);
return convertView;
}
}
}

It is related to checkbox item in connections.xml which is the list row item. If I remove checkbox, related listeners responses. I think, it may be thought there is no need a setItemOnClickListener(..) method since each row has a checkbox. Or it is a bug.
