I have a Listview of EditText and I need to get the String values of each edited row when I click a confirm button, but I don't know how.
I have tried to adapt some sample with no success ( I get always the default values and not the edited values).
My attempt is this
public class MyActivity extends Activity {
static int nItems;
ImageButton confirmButton;
ListView myList;
ListViewAdapterEditText adapterG1, adapterG2, adapterG3;
#Override
public void onCreate(Bundle savedInstanceState) {
.....
myList = (ListView) findViewById(R.id.listaG1);
myList.setItemsCanFocus(true);
adapterG1 = new ListViewAdapterEditText();
myList.setAdapter(adapterG1);
}
OnClickListener mConfirmButtonListener = new OnClickListener() {
public void onClick(View v) {
ArrayList a1 = adapterG1.getItems();
for (int i = 0; i < nItems; i++) {
System.out.println(a1.get(i)
+ "\n\n");
}
};
public class ListViewAdapterEditText extends BaseAdapter {
private LayoutInflater mInflater;
public ArrayList myItems = new ArrayList();
ListItem listItem;
public ListViewAdapterEditText() {
mInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
for (int i = 0; i < nItems; i++) {
listItem = new ListItem();
listItem.caption = "Caption" + i;
myItems.add(listItem);
}
notifyDataSetChanged();
}
public int getCount() {
return myItems.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public ArrayList<String> getItems() {
ArrayList<String> items = new ArrayList<String>();
for (int i = 0; i < nItems; i++) {
ListItem li = (ListItem) myItems.get(i);
items.add(li.getCaption());
}
return items;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.list_item_row,
null);
holder.caption = (EditText) convertView
.findViewById(R.id.ItemCaption);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
// Fill EditText with the value you have in data source
holder.caption.setText(((ListItem) myItems.get(position)).caption);
// holder.caption.setText(myItems.get(position).caption);
holder.caption.setId(position);
// we need to update adapter once we finish with editing
holder.caption
.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
final int position = v.getId();
final EditText Caption = (EditText) v;
((ListItem) myItems.get(position)).caption = Caption
.getText().toString();
}
}
});
return convertView;
}
class ViewHolder {
EditText caption;
}
class ListItem {
String caption;
public String getCaption() {
return caption;
}
}
}
}
Could someone help me to solve this problem?
Are you sure your OnFocusChangeListener is called? If you edit the text in EditText then tap the confirm button, this listener will not be called in touch mode since the focus is still on the EditText.
Update: Consider the situation you edited the text in a EditText while didn't confirm and scrolled the ListView so that the item view is recycled, I'm not sure what is your preferred way, but if you want store the edited data, you can use setRecyclerListener(android.widget.AbsListView.RecyclerListener) to get notified when a item view is recycled so you can saved the edit result. To save the result of EditText showing on screen, you use methods like getChildAt to get item views visible on screen then get the EditText's text.
Update2: Another better and clean way is use TextWatcher and addTextChangeListener, this will notifies you when the text in EditText is changed.
Update3: I just write the following sample and test it, and it works on my phone. :)
Update4: I removed the previous code cause its performance is bad and creates a lot objects, you can check the following full sample instead:

/////most important returning your array so you can use it in the Activity

Now I am displaying images in grid-view, it working fine. In that grid-view i am going to select few images, i want store selected multiple images position in array variable (example: if i select position 1, 4 ,10. i want that particular position id and i want to store it array like 1,4,10,15,). I will put my activity and adapter code below. Thank you in advance.

It's simple. You can use SparseBooleanArray for this purpose. Just add the following methods as is in your adapter:
public void toggleSelection(int item) {
if (selectedItems.get(item, false)) {
selectedItems.delete(item);
} else {
selectedItems.put(item, true);
}
notifyDataSetChanged();
}
public void setSelectedItems(List<Object> objects) {
if (objects != null) {
for (Object object : objects) {
toggleSelection(object.getId());
}
notifyDataSetChanged();
}
}
public void clearSelections() {
selectedItems.clear();
notifyDataSetChanged();
}
public int getSelectedItemCount() {
return selectedItems.size();
}
public List<Integer> getSelectedItems() {
List<Integer> items =
new ArrayList<Integer>(selectedItems.size());
for (int i = 0; i < selectedItems.size(); i++) {
items.add(selectedItems.keyAt(i));
}
return items;
}
Use the set selection method to store the selected status of your item.
Don't forget to initialize SparseBooleanArray in your constructor.
SparseBooleanArray SparseBooleanArray = new SparseBooleanArray();
After that, use toggleSelection(position); to change the selected status of an item, then after performing selections, call getSelectedItem() to get the selected items in an array.
// create an Arraylist and add the selected position in a list
List <int> selectedArray = new ArrayList<>();
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
int click = (int) parent.getItemAtPosition(position);
selectedArray.add(click);
}
I have created a list with a custom row but I do not know what's wrong.
This is the main activity
package com.example.fahdmana.lest;
public class MainActivity extends AppCompatActivity{
ListView listView;
final int[] movie_poster_resouce = {
R.drawable.apple,
R.drawable.banana,
R.drawable.cherry,
R.drawable.mango,
R.drawable.orange,
R.drawable.strawberry,
R.drawable.tomato
};
String[]movies_title;
String[]movies_rating;
MovieAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView)findViewById(R.id.List1);
movies_title = getResources().getStringArray(R.array.Movies_names);
movies_rating = getResources().getStringArray(R.array.Ratings);
int i =0;
for (String titles : movies_title){
MovieDataProvider dataProvider =
new MovieDataProvider(movie_poster_resouce[i],titles,movies_rating[i]);
i++;
adapter = new MovieAdapter(getApplicationContext(),R.layout.row);
listView.setAdapter(adapter);
adapter.add(dataProvider);
}
}
}
And this is my adapter
package com.example.fahdmana.lest;
import android.content.Context;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.List;
public class MovieAdapter extends ArrayAdapter {
final List list = new ArrayList();
public MovieAdapter( Context context, int resource) {
super(context, resource);
}
static class DataHandeler{
ImageView poster;
TextView title;
TextView rating;
}
#Nullable #Override
public void add( Object object) {
super.add(object);
list.add(object);
}
#Nullable #Override
public int getCount() {
return list.size();
}
#Nullable #Override
public Object getItem(int position) {
return this.list.get(position);
}
#Nullable #Override
public View getView (int position,
#NonNull View convertView,
#NonNull ViewGroup parent) {
View row;
row = convertView;
DataHandeler handler;
if (convertView ==null) {
LayoutInflater inflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.row, parent, false);
handler = new DataHandeler();
handler.poster = (ImageView) row.findViewById(R.id.image_view);
handler.title = (TextView) row.findViewById(R.id.movie_title);
handler.rating = (TextView) row.findViewById(R.id.movie_rating);
row.setTag(handler);
} else {
handler = (DataHandeler) row.getTag();
}
MovieDataProvider dataProvider;
dataProvider = (MovieDataProvider)this.getItem(position);
handler.poster.setImageResource(dataProvider.
getMovie_poster_resource());
//here i get some warning
handler.title.setText(dataProvider.getMovie_title());
handler.rating.setText(dataProvider.getMovie_rating());
return row;
}
}
And this is my data provider
package com.example.fahdmana.lest;
public class MovieDataProvider {
private int movie_poster_resource;
private String movie_title;
private String movie_rating;
public MovieDataProvider(int movie_poster_resource, String movie_title, String movie_rating){
this.setMovie_poster_resource(movie_poster_resource);
this.setMovie_title(movie_title);
this.setMovie_rating(movie_rating);
}
public int getMovie_poster_resource() {
return movie_poster_resource;
}
public void setMovie_poster_resource(int movie_poster_resource) {
this.movie_poster_resource = movie_poster_resource;
}
public String getMovie_title() {
return movie_title;
}
public void setMovie_title(String movie_title) {
this.movie_title = movie_title;
}
public String getMovie_rating() {
return movie_rating;
}
public void setMovie_rating(String movie_rating) {
this.movie_rating = movie_rating;
}
}
I am pretty sure this is your problem.
for (String titles : movies_title){
MovieDataProvider dataProvider =
new MovieDataProvider(movie_poster_resouce[i],titles,movies_rating[i]);
i++;
adapter = new MovieAdapter(getApplicationContext(),R.layout.row);
listView.setAdapter(adapter);
adapter.add(dataProvider);
}
You have this in your main activity. You really dont want to loop through your list and inside of that loop call your adapter.
You want to create a list of your objects and then call the adapter .... something like this...
ListViewAdapterResults adapter = new ListViewAdapterResults(listView.getContext(), scheduleModelList);
listView.setAdapter(adapter);
Where scheduleModelList is my list of objects. Hopefully that makes sense.
Happy coding.
Looking through your code, you may want to do something like this....
Put this at the top
List<MovieDataProvider> list;
Then this right after your setContentView
list = new ArrayList<>();
Replace that loop you have with this:
for (int i = 0; i < movie_title.length; i++) {
list.add(new MovieDataProvider(movie_poster_resouce[i],titles,movies_rating[i]));
}
MovieAdapter adapter = new MovieAdapter(listView.getContext(), list);
listView.setAdapter(adapter);
Let me know if you have any questions.
MovieAdapter (this is your adapter class)
listView.getContext() (this is the ID of your listview [you may have it named something else])
It's been a very long time since I have worked with Arrays.... you have have to +1 or -1 inside of the for loop. (i < movie_title.length [maybe +1 or -1])

notifyDataSetChanged();

});
return row;

}
}
When I used above function for sending message but error is that when I click on any CheckBox to send that message then automatically Different Message is sent to another activity. so, I want to get particular message position to sent it.
You can set "setOnItemClickListener" on list view and get the position.
ListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// Here you can get the position
}
});

Hi guys I have a question:
I created a listview, with search-bar etc . So when I click on an item (through switch-case) the selected new activity opens and there are no problems.
you can see the code here:
Filtered list item opens the original list items' activity
The problems start when I filter the listview, with the search-bar, and instead of opening the selected activity (let us say activity 10), it throws me back to activity 1 and so forth.
What I have figured out so far is that most probably the CustomAdapter somehow mixes my activities and does not know which activity was chosen; hence, it throws me back to the beginning.
Please guys, I am trying for over a month to solve that issue and still no hope in the horizon.
Any help appreciated.
In your code, you have given click event based on the position of listview. eg:
players = {"test1","test2","test3"}
CASE 1: when nothing is searched:
first position has player test1
case 2: when user search test2.
Now listview search for test2 and find only one instance of this, and searchlist will have only one player and it will be at the first position. Since you have given click event based on position it, first row will always take to Barca
UPDATE:
you need to change your Code as below

I have implemented a custom adapter class for controlling my listview. I'm implementing a button, a textbox and a checkbox against each row in the listview. I have a couple of buttons that are not part of the listview. They are below the listview. Now when I check any number of boxes and press the button that is not part of the listview, I want to be able to delete the checked boxes (if there are any). In other words, I want to b able to delete the checked items with the click of a button that is not part of the listview.
Here's my main class...
public class ASvideofiles extends Activity implements OnClickListener {
int count = 0;
private String[] vidNames;
private String[] vidPaths;
private ListView myList;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.asvideofiles);
Button b1 = (Button) findViewById(R.id.button1);
b1.setOnClickListener(this);
Button b2 = (Button) findViewById(R.id.button2);
b2.setOnClickListener(this);
File f = new File(Environment.getExternalStorageDirectory(),
"ABC/XYZ/");
File[] files = f.listFiles();
vidNames = new String[files.length];
vidPaths = new String[files.length];
if(files != null) {
for(int i=0; i < files.length; i++) {
vidNames[i] = files[i].getName();
vidPaths[i] = files[i].getPath();
count ++;
}
}
ArrayList<String> list = new ArrayList<String>();
for (int i = 0; i < files.length; i++) {
list.add(vidNames[i]);
}
myList = (ListView)findViewById(R.id.listView1);
myList.setAdapter(new AScustomadapter(ASvideofiles.this, list));
}
#Override
public void onClick(View v) {
if(v.getId() == R.id.button1) {
} else if(v.getId() == R.id.button2) {
}
}
}
Here's my Adapter class...
public class AScustomadapter extends BaseAdapter {
private ArrayList<String> mListItems;
private LayoutInflater mLayoutInflater;
int i = 0;
private ArrayList<Integer> checkedIndices = new ArrayList<Integer>();
public AScustomadapter(Context context, ArrayList<String> arrayList) {
mListItems = arrayList;
//get the layout inflater
mLayoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return mListItems.size();
}
#Override
public Object getItem(int i) {
return null;
}
#Override
public long getItemId(int i) {
return 0;
}
public int getTotalCheckedCount() {
return checkedIndices.size();
}
#Override
public View getView(final int position, View view, ViewGroup viewGroup) {
ViewHolder holder;
if (view == null) {
holder = new ViewHolder();
view = mLayoutInflater.inflate(R.layout.list_item, null);
holder.itemName = (TextView) view.findViewById(R.id.list_item_text_view);
holder.cb1 = (CheckBox) view.findViewById(R.id.checkBox1);
view.setTag(holder);
} else {
holder = (ViewHolder)view.getTag();
}
final String stringItem = mListItems.get(position);
if (stringItem != null) {
if (holder.itemName != null) {
holder.itemName.setText(stringItem);
}
}
holder.cb1.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
if(checkedIndices.contains(position)){
}else {
checkedIndices.add(position);
}
}else {
checkedIndices.remove((Integer)position);
}
}
});
if(checkedIndices.contains((Integer)position)) {
holder.cb1.setChecked(true);
} else {
holder.cb1.setChecked(false);
}
//this method must return the view corresponding to the data at the specified position.
return view;
}
private static class ViewHolder {
protected TextView itemName;
protected CheckBox cb1;
}
}
The rows are basically populated with videos, so all in all, I want to be able to delete the selected videos against which the check boxes are checked and the delete button is pressed. Help required. Thanks in advance.
Maintain a Boolean Array which keeps track of the position of the rows of checked CheckBoxes.
Then in your Button onClickListener remove those items from the ArrayList and pass this updated ArrayList to your adapter.
Finally call notifyDataSetChanged()
Here , i have a solution for you. I have added your adapter class in the main activity itself. Basically i have created two array list of type string. When you check a checkbox, the corresponding textview value is stored in it the list CHECKEDLIST. In the other list ALLVALUES, all the values are stored.
On button click i match both the lists and if a match occurs, then i remove that value from ALLVALUES and call notifydatasetchanged
