Selection of all check boxes in listview

Selection of all check boxes in listview - android

I want to select all check boxes in a listview but I'm not able to get checkbox objects from the listview. I can select a single check box but not multiple check boxes.
Your suggestion are appreciable.
Code:
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle icicle) {
super.onCreate(savedInstanceState);
setContentView(R.layout.bir);
mainListView = (ListView) findViewById(R.id.mainListView);
selectall = (Button) findViewById(R.id.button1);
selectall.setOnClickListener(this);
save = (Button) findViewById(R.id.button2);
save.setOnClickListener(this);
mainListView.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> parent, View item,
int position, long id) {
}
});
}
}
class Amphian:
private static class Amphian
{
private String name = "" ;
private boolean checked = false ;
public Amphian( String name )
{
this.name = name ;
}
public Amphian( String name, boolean checked )
{
this.name = name ;
this.checked = checked ;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public boolean isChecked() {
return checked;
}

this.checked = checked;
}
#Override

return name ;
}
public void toggleChecked()
{
checked = !checked ;
}
}

}
#Override

mp=new MediaPlayer();
if ( convertView == null )
{

// Find the child views.
textView = (TextView) convertView.findViewById( R.id.rowTextView );
checkBox = (CheckBox) convertView.findViewById( R.id.checkBox1 );
button = (Button)convertView.findViewById(R.id.button1);
// Optimization: Tag the row with it's child views, so we don't have to
// call findViewById() later when we reuse the row.
convertView.setTag( new AmphianViewHolder(textView,checkBox,button) );
// If CheckBox is toggled, update the planet it is tagged with.
checkBox.setOnClickListener( new View.OnClickListener()
{
#Override
public void onClick(View v)
{
cb= (CheckBox) v;
Log.e("cb",String.valueOf(cb));
Amphian amphian = (Amphian) cb.getTag();

There is too much code to read, so I give you a sample how to do that:
int count = list.getCount();
for (int i = 0; i < count; i++) {
View child = list.getItemAtPosition(i);
//check that child..
}
or
int count = list.getChildCount();
for (int i = 0; i < count; i++) {
View child = list.getChildAt(i);
//check that child..
}

selectall.setOnClickListener(new onClickListener(){
#Override
public void onClick(View v) {
for (int i = 0; i < list.size(); i++) {
list.getItem(i).setChecked(true);
}
}
});
try doing soething like this

Update your code as below. Set choice mode to CHOICE_MODE_SINGLE when you crate listview and before set adapter. Remove CHOICE_MODE_SINGLE from button click.
listview = (ListView) findViewById(R.id.listview1);
listview.setChoiceMode(AbsListView.CHOICE_MODE_SINGLE);
listview.setAdapter(adapter);
Also, You need to setItemChecked in onItemClick of listview.
Check below example code.
public class MainActivity extends Activity {
private ListView mListView;
private String[] mData = new String[] { "xxx", "yyy", "zzz", "aaa" };
private BaseAdapter mAdapter;
private int mLastCorrectPosition = -1;
private int mButtonPosition = 0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mListView = (ListView) findViewById(R.id.list_view);
mListView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
mAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_activated_1, mData);
mListView.setAdapter(mAdapter);
mListView.setSelector(new ColorDrawable(0));
mListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
if (position == mButtonPosition) {
if (mLastCorrectPosition != -1) {
mListView.setItemChecked(mLastCorrectPosition, true);
}
else {
mListView.setItemChecked(mButtonPosition, false);
}
// here show dialog
}
else {
mLastCorrectPosition = position;
// here refresh fragment
}
}
});
}
}

Problem
First item in the list maps to 5th item. 2nd item to sixth item. I mean if I change radio button at the first item, Same radio button gets selected at the 5th list item also.
Any suggestions?
Is it because of recycling?
How do I resolve it?
I tried saving in Question object and retrieving it. I used pos to retrieve and set. But same problem still exist.

I would use Action Mode with MultiChoiceModeListener.
http://developer.android.com/reference/android/widget/AbsListView.MultiChoiceModeListener.html
There is a callback onItemCheckedStateChanged(ActionMode mode, int position, boolean checked).
You can easily get values of already checked list items ListView.getCheckedItemPositions. So you can prevent selection, if you already selected two or even at once pass the values(or ids) of selected ones without any effort.

You can simply put a counter on item selection.
Take a variable say for ex.
int count = 0;
Check this variable before marking item as selected/deselected:
if(item.isSelected())
{
// you need to make is disable
if(count>0)
{
count--;
// // mark item as deselected
}
}
else
{
// make it selected
if(count<2)
{
count++;
// mark item as selected
}
}
This will make you select ONLY TWO items at a time.
Modify your adapter like this:
public class LoadAdapter extends BaseAdapter {
private ArrayList<DataBase> mProductItems;
private LayoutInflater mLayoutInflater;
private Context mContext;
DBHelper mydb;
DataBase stringItem;
ArrayList<Boolean> selected = new ArrayList<>();
private int count=0;
public LoadAdapter(Context context, ArrayList<DataBase> arrayList){
mContext = context;
mProductItems = arrayList;
mLayoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
for (int i = 0; i < arrayList.size(); i++) {
selected.add(false);
}
}
#Override
public int getCount() {
// TODO Auto-generated method stub
Log.e("testtt", String.valueOf(mProductItems.size()));
return mProductItems.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
final ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = mLayoutInflater.inflate(R.layout.load_chart_item, parent, false);
holder.txtv_name = (TextView) convertView.findViewById(R.id.text);
holder.nameid = (TextView) convertView.findViewById(R.id.nameid);
holder.btn_delete = (Button) convertView.findViewById(R.id.btn_delete);
holder.btn_edit = (Button)convertView.findViewById(R.id.btn_edit);
holder.location = (TextView)convertView.findViewById(R.id.loc);
holder.btn_delete.setTag(position);
convertView.setTag(holder);
} else {
holder = (ViewHolder)convertView.getTag();
}
mydb = new DBHelper(mContext);
stringItem = mProductItems.get(position);
if (stringItem != null) {
if (holder.txtv_name != null) {
holder.txtv_name.setText(stringItem.getName());
holder.nameid.setText(stringItem.getId());
holder.location.setText(stringItem.getLocation());
Log.e("saved Location values",stringItem.getLocation());
}
}
if(selected.get(position))
{
//for selected row
holder.txtv_name.setTextColor(color.red);
}
else
{
// for not selected row
holder.txtv_name.setTextColor(color.black);
}
holder.txtv_name.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(holder.txtv_name.getCurrentTextColor()== R.color.black)
{
//is not selected
if(count<2)
{

selected.set(position,true);
// mark item as selected
}
}
else
{
//is selected
if(count>0)
{

selected.set(position,false);
// // mark item as deselected
}
}
notifyDataSetChanged();
}
});
holder.btn_delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
DataBase test = mProductItems.get(position);
String id = test.getId();
mydb.deleteContact(Integer.valueOf(id));
mProductItems.remove(mProductItems.get(position));
LoadAdapter.this.notifyDataSetChanged();
if (mProductItems.size() == 0){
mProductItems.clear();
LoadAdapter.this.notifyDataSetChanged();
}
}
});
Log.e("DataBase", String.valueOf(mydb.getAllCotacts()));
holder.btn_edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent=new Intent(mContext,UpdateData.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

{
this.mProductItems = items;
notifyDataSetChanged();
}
private static class ViewHolder {
TextView txtv_name,nameid,location;
Button btn_delete,btn_edit;
}}
EDIT 2: For getting selected items from adapter define below method in
adapter and call it with an adapter object like : adp.getSelected()
public String getSelected() {
String selectedString = "";
int num=0;
for (int i = 0; i < selected.size(); i++) {
if (selected.get(i)) {
num++;
if (num == 1) {
selectedString = mProductItems.get(i).getName();
} else {
selectedString += "," + mProductItems.get(i).getName();
}
}
}
return selectedString;
}
Answer to issue 2 : If you want to use ImageView instead of text color change. The do the same things as above but replace the TextView + Color with ImageView + Image.
EDIT 3:
You have called the getSelected() method from a Null object. Modify your code like this:
listView = (SwipeListView) findViewById(R.id.listview);
loadAdapter = new LoadAdapter(getApplicationContext(),array_list);
listView.setAdapter(loadAdapter);
det.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String str = "";
str = loadAdapter.getSelected();
Toast.makeText(RelationShipChartList.this, str, Toast.LENGTH_SHORT).show();
}

custom listview edit value

i have EditText in second activity.so the value enter here will be added to the custom listview in first activity.
i first activity in list i have textview,checkbox and button(edit). here textview will be from second activity edittext data. so here if i click on edit then it navigates to second activity of that particular data .am getting all these now .. in second acitity i want to edit the textfield value .so it has to display the edited value with this data in listview of particular row.

You are adding the edited data to the ArrayList Again avoid it inside the Second Activity
app.cardNumberData = cardNumber.getText().toString();
if(arryList.indexOf(cardNumberReceived) != -1)
{
app.arryList.set(arryList.indexOf(cardNumberReceived), app.cardNumberData);
}else
{
app.arryList.add(app.cardNumberData);
}
In your second Activity do this onClick of save.
