Sorry, I edit all code and I make project chat firebase and show listview listroom for add user and delete user and manageroom. It deletes room edit nameroom. Same I need to click imagebutton for delete listroom.

how to get all checked value on button click from list-view in android

This is my adapter class :
public class CheckboxAdapter extends ArrayAdapter<String> {
private LayoutInflater mInflater;
Context context;
private String[] mStrings;
private TypedArray mIcons;
private int mViewResourceId;
ArrayList<String> selectedStrings = new ArrayList<String>();
public CheckboxAdapter(Context ctx, int viewResourceId, String[] strings) {
super(ctx, viewResourceId, strings);
mInflater = (LayoutInflater) ctx
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mStrings = strings;
mViewResourceId = viewResourceId;
}
public int getCount() {
return mStrings.length;
}
public String getItem(int position) {
return mStrings[position];
}
public long getItemId(int position) {
return 0;
}
public View getView(int position, View convertView, ViewGroup parent) {
convertView = mInflater.inflate(mViewResourceId, null);
final CheckBox tv = (CheckBox) convertView.findViewById(R.id.checkBox1);
tv.setText(mStrings[position]);
tv.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
// TODO Auto-generated method stub
if (isChecked) {
selectedStrings.add(tv.getText().toString());
Toast.makeText(buttonView.getContext(),Boolean.toString(selectedStrings.add(tv.getText().toString())), Toast.LENGTH_SHORT).show();
} else {

}
}
});
return convertView;
}
}
This is my actvity
public class AddTime extends Activity {
CheckboxAdapter cadpter;
String daya[] = { "Sunday", "Monday", "Tuesday", "Wednesday", "Thrusday",
"Friday", "Saturday" };
ListView list;
ArrayList<String> selectedStrings = new ArrayList<String>();
#Override

// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.addtime);

I am displaying all day in listview also i have display check box with each day when i enable check box it show true in toast but i want what ever i select day using check box i mean i want display all the day in textview in mainactvity please suggest me how i will get it .

how to get all checked value on button click from list-view in android
As adding all checked values in selectedStrings ArrayList. create a method in CheckboxAdapter class which return ArrayList of all selected values. for example :
public ArrayList<String> getAllSelectedValues(){
return this.selectedStrings;
}
Now use cadpter CheckboxAdapter class object for accessing getAllSelectedValuesmethod in Activity:
ArrayList<String> selectedStrings=cadpter.getAllSelectedValues();

get all values from selectedStrings arrayList
for(int i=0;i<=selectedStrings.sizes();i++){
String s =selectedStrings.get(i);
}

Take boolean Array
ArrayList<Boolean> selectedStrings = new ArrayList<>();
and add onClickListener in your checkbox
public View getView(final int position, View convertView, ViewGroup parent) {
-
-
tv.setChecked(false);
if(selectedStrings.size() <= position){
selectedStrings.add(position, false);
}else
tv.setChecked(selectedStrings.get(position));
tv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
boolean state = selectedStrings.get(position);
selectedStrings.remove(position);
selectedStrings.add(position, state ? false : true);
}
});
}

The cause of this is that when you call nameCheckBox.setChecked() in code OnClickListener() awakes and run its code. I had the same problem an solved in just setting OnClickListener(null) before set a checkbox checked or not.

nameCheckBox.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
isChecked[position_clicked] = position;
Log.d("position", String.valueOf(position));
}
});
this code in add more one arre list in stores all position and add or remove both said
fast add ,second remove.
and used to list in position your other method

My ListView consist an ImageView and a TextView i need to get the Text from the TextView

My ListView consist an ImageView and a TextView I need to get the Text from the TextView.
int the position of my list where I press (onItemClick).
How can I do that?
The 1 class have a Button then when you press I moving to the next activity (CountryView)
and expect to get back from the next activity with a text (name of the selected Country)
The 2 classes have a ListView (ImageView and TextView) the data is getting from a database and showing on the ListView.
My problem is to get back to the 1 class the selected name of the country.
Thanks so much for helping!!!

When you add things to the list, you can add hashmaps to the arraylist which the adapter looks at. Then you can grab the values which are name value pairs.

I think you want to get the position of the list you clicked, Its simple you can use OnItemClickListener as follows
YourList.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
int position=arg2;
// where position is the clicked position
} }
If you stored your data in String array pass this position say array[position] to string array you can get the Text..
