Dialog file to update list rows does not work / OnItemLongClick

I managed to get Dialog to show up on the long click by implementing this code:
ListView list = getListView();
list.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
new EditListItemDialog(view.getContext()).show();
return true;
}
});
Unfortunately, when the dialog opens and prompts for new text input, when clicked ok, no changes are made to the list.
Here is the Dialog file:
package com.example.classorganizer;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
class EditListItemDialog extends Dialog implements View.OnClickListener {
private View editText;
public EditListItemDialog(Context context) {
super(context);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_text_dialog);//here is your xml with EditText and 'Ok' and 'Cancel' buttons
View btnOk = findViewById(R.id.button_ok);
editText = findViewById(R.id.edit_text);
btnOk.setOnClickListener(this);
}
#Override
public void onClick(View v) {
((TextView) editText).getText().toString();//here is your updated(or not updated) text
dismiss();
}
}
Here is the file containing list:
package com.example.classorganizer;
import java.util.ArrayList;
import android.app.ListActivity;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;

import android.widget.ListView;
import android.widget.TextView;
import com.cookbook.data.Constants;
import com.cookbook.data.MyDB;
public class Monday extends ListActivity {
private static final int MyMenu = 0;
MyDB dba;
DiaryAdapter myAdapter;
private class MyDiary{
public MyDiary(String t, String c){
title=t;
content=c;
ListView list = getListView();
list.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
new EditListItemDialog(view.getContext()).show();
return true;
}
});
}
public String title;
public String content;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
dba = new MyDB(this);
dba.open();
setContentView(R.layout.fragment_monday);
super.onCreate(savedInstanceState);
myAdapter = new DiaryAdapter(this);
this.setListAdapter(myAdapter);
}
private class DiaryAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<MyDiary> fragment_monday;
public DiaryAdapter(Context context) {
mInflater = LayoutInflater.from(context);
fragment_monday = new ArrayList<MyDiary>();
getdata();
}
public void getdata(){
Cursor c = dba.getdiaries();
startManagingCursor(c);
if(c.moveToFirst()){
do{
String title =
c.getString(c.getColumnIndex(Constants.TITLE_NAME));
String content =
c.getString(c.getColumnIndex(Constants.CONTENT_NAME));
MyDiary temp = new MyDiary(title,content);
fragment_monday.add(temp);
} while(c.moveToNext());
}
}
#Override
public int getCount() {return fragment_monday.size();}
public MyDiary getItem(int i) {return fragment_monday.get(i);}
public long getItemId(int i) {return i;}
public View getView(int arg0, View arg1, ViewGroup arg2) {
final ViewHolder holder;
View v = arg1;
if ((v == null) || (v.getTag() == null)) {
v = mInflater.inflate(R.layout.diaryrow, null);
holder = new ViewHolder();
holder.mTitle = (TextView)v.findViewById(R.id.name);
v.setTag(holder);
} else {
holder = (ViewHolder) v.getTag();
}
holder.mdiary = getItem(arg0);
holder.mTitle.setText(holder.mdiary.title);
v.setTag(holder);
return v;
}
public class ViewHolder {
MyDiary mdiary;
TextView mTitle;
}
}
/** Called when the user clicks the Edit button */
public void visitDiary(View view) {
Intent intent = new Intent(this, Diary.class);
startActivity(intent);
}
/** Called when the user clicks the back button */
public void visitSchedule(View view) {
Intent intent = new Intent(this, DisplayScheduleScreen.class);
startActivity(intent);
}
}
Here is an xml file for dialog:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/relativeLayout4"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" >
<EditText
android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10" >
<requestFocus />
</EditText>
<Button
android:id="#+id/button_ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="OK" />
</RelativeLayout>
</LinearLayout>
I don't understand why the rows are not being updated with data entered through Dialog file...

#Override
public void onClick(View v) {
((TextView) editText).getText().toString();//here is your updated(or not updated) text
dismiss();
}
You are getting the value from TextView of the dialog ,have u added the data to the list.
Update the data to the list
fragment_monday.add(((TextView) editText).getText().toString());

is it possible to edit field from listview on long click action?

Is it possible to have such functionality in android? When user longclicks row in a list popup window opens with option to edit content?

Yes it is. First of all you need to create your own Dialog with appropriate xml:
private static class EditListItemDialog extends Dialog implements View.OnClickListener {
private EditText editText;
public EditListItemDialog(Context context) {
super(context);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_text_dialog);//here is your xml with EditText and 'Ok' and 'Cancel' buttons
Button btnOk = findViewById(R.id.button_ok);
editText = findViewById(R.id.edit_text);
btnOk.setOnClickListener(this);
}
#Override
public void onClick(View v) {
editText.getText().toString();//here is your updated(or not updated) text
dismiss();
}
}
Then add listener at setOnLongClickListener:
ListView listView = new ListView(this);
listView.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
new EditListItemDialog(v.getContext()).show();
return true;
}
});
Finally you need to update data in your ListView. The right way is to update Adapter of your list view which finally will update ListView.

Ok, I managed to make Dialog file as in your example:
package com.example.classorganizer;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
class EditListItemDialog extends Dialog implements View.OnClickListener {
private View editText;
public EditListItemDialog(Context context) {
super(context);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_text_dialog);//here is your xml with EditText and 'Ok' and 'Cancel' buttons
View btnOk = findViewById(R.id.button_ok);
editText = findViewById(R.id.edit_text);
btnOk.setOnClickListener(this);
}
#Override
public void onClick(View v) {
((TextView) editText).getText().toString();//here is your updated(or not updated) text
dismiss();
}
}
I created an xml file for Dialog file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<EditText
android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10" >
<requestFocus />
</EditText>
<Button
android:id="#+id/button_ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="OK" />
</LinearLayout>
Then I updated my Display List file with this code:
ListView listView = new ListView(Monday.this);
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
new EditListItemDialog(view.getContext()).show();
return true;
}
});
And here is full file that displays list of rows to be edited upon Long Click:
import java.util.ArrayList;
import android.app.ListActivity;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.ListView;
import android.widget.TextView;
import com.cookbook.data.Constants;
import com.cookbook.data.MyDB;
public class Monday extends ListActivity {
private static final int MyMenu = 0;
MyDB dba;
DiaryAdapter myAdapter;
private class MyDiary{
public MyDiary(String t, String c){
title=t;
content=c;
}
public String title;
public String content;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
dba = new MyDB(this);
dba.open();
setContentView(R.layout.fragment_monday);
super.onCreate(savedInstanceState);
myAdapter = new DiaryAdapter(this);
this.setListAdapter(myAdapter);
}
private class DiaryAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<MyDiary> fragment_monday;
public DiaryAdapter(Context context) {
mInflater = LayoutInflater.from(context);
fragment_monday = new ArrayList<MyDiary>();
getdata();
//new code below
ListView listView = new ListView(Monday.this);
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
new EditListItemDialog(view.getContext()).show();
return true;
}
}); //end of new code
}
public void getdata(){
Cursor c = dba.getdiaries();
startManagingCursor(c);
if(c.moveToFirst()){
do{
String title =
c.getString(c.getColumnIndex(Constants.TITLE_NAME));
String content =
c.getString(c.getColumnIndex(Constants.CONTENT_NAME));
MyDiary temp = new MyDiary(title,content);
fragment_monday.add(temp);
} while(c.moveToNext());
}
}
#Override
public int getCount() {return fragment_monday.size();}
public MyDiary getItem(int i) {return fragment_monday.get(i);}
public long getItemId(int i) {return i;}
public View getView(int arg0, View arg1, ViewGroup arg2) {
final ViewHolder holder;
View v = arg1;
if ((v == null) || (v.getTag() == null)) {
v = mInflater.inflate(R.layout.diaryrow, null);
holder = new ViewHolder();
holder.mTitle = (TextView)v.findViewById(R.id.name);
v.setTag(holder);
} else {
holder = (ViewHolder) v.getTag();
}
holder.mdiary = getItem(arg0);
holder.mTitle.setText(holder.mdiary.title);
v.setTag(holder);
return v;
}
public class ViewHolder {
MyDiary mdiary;
TextView mTitle;
}
}
/** Called when the user clicks the Edit button */
public void visitDiary(View view) {
Intent intent = new Intent(this, Diary.class);
startActivity(intent);
}
/** Called when the user clicks the back button */
public void visitSchedule(View view) {
Intent intent = new Intent(this, DisplayScheduleScreen.class);
startActivity(intent);
}
}
There you can see where I put the new code. Unfortunately, upon long click row is not being updated. I mean, the dialog file seems that is not being launched. Is it because I put the code in the wrong place or am I missing something else?

EditTexts are not designed to be used inside ListViews. Alternatively you could use a ScrollView and populate the EditTexts dynamically.

How to send selected messages using checkbox to a particular no?

first i'm fetching all messages to my app to be store in listview then I'm selecting messages from listview using checkboxes and wish to send these selected sms to a single number that is predefined and wish to use the selected sms as body of message to be send to single no. but the problem is that the message sent contains complete listview messages not the selected one. So please someone correct me where i'm wrong in code as i wish to send only selected messages not the complete listview items(messages)

How to add EditText in listview and get its value dynamically in all the rows?

I have Checkbox and EditText and a Textview in a listView. It gets value for the text view from a list. Checkbox will be checked dynamically. In the same way EditText also can be entered dynamically. Now my problem is, When i scroll the list view (up and down) after entering the text in the Edit text, I could not get the typed value. I check the check box also like that. But using the position, I set it correct. I Could not know How to set the EditText value to the list properly. Please help me. Here is my code:
main.xml: (Main xml for launch)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/my_list"
android:layout_width="fill_parent"
android:layout_height="250px" />
<Button
android:text="Save"
android:id="#+id/btnSave"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
row.xml: (ListView Row)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<TextView
android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#+id/label"
android:textSize="30sp"/>
<CheckBox
android:id="#+id/check"

There is no error in the code. It runs well. I could maintain the checkbox position and display at the same position even I scroll up and down. But I could not get and set the EditText value properly. Please Help me out.
Thanks in advance.

you can achieve this using the custom list view.
find the example of listview with edittext is here

Easy and beautiful solution to handle EditText with listView:
(Does not require holder or RecycleView or anything else)
Brief explaination:
1) In getView method when you inflate the view, apply the myTextWatcher the editText. Pass this EditText to the myTextWatcher()
2) Inside getView Method find that EditText and set position as editText.setTag [Each time. not only when the view was inflated.]
3) Define MyTextWatcher. It should have reference to EditText on which it is applied.
4) myTextWatcher.onTextChanged() will read the tag set to the editText and do the required work
Modify your getView() method of Adapter class:
#Override
public View getView(int position, View convertView, final ViewGroup parent) {
if(convertView==null){
convertView = LayoutInflater.from(getContext()).inflate(R.layout.single_row_layout,parent,false);
EditText et = convertView.findViewById(R.id.idEditText);
et.addTextChangedListener(new MyTextWatcher(et));
}
//This is again required to find reference to EditText... so that 'position' can be applied on to it as 'tag' EACH time.
EditText editText = (EditText) convertView.findViewById(R.id.idEditText);;
//This tag will be used inside onTextChanged()
editText.setTag(position);
}
Define your MyTextWatcher class as:
private class MyTextWatcher implements TextWatcher{
//int position;
EditText et;
public MyTextWatcher(EditText editText){
this.et = editText;
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if(et.getTag()!=null){
// This is required to ensure EditText is edited by user and not through program
if(et.hasFocus()){
int position = (int)et.getTag();
String newText = et.getText()+"";
//Implement your actions here........
//you can get require things/ views from listView.getChildAt(position)..
}
}
}
#Override
public void afterTextChanged(Editable s) {
}
}

Just keep viewHolder.address.setTag(position) and it works perfect cheers.
