I am having a little trouble with listview, I want to get values of listview whose checkbox are selected when button is clicked. till now i have created a listview with checkboxes and fetched all the values from mysql but i am not able to get values of listview which are checked.
This is my class
public class ListViewMultipleSelectionActivity extends Activity{
Button button;
String myJSON;
private static final String TAG_NAME = "cat_name";

button = (Button)findViewById(R.id.testbutton);
getlat();
button.setOnClickListener(new OnClickListener() {

i have implemented this on testbutton(Button) click please check
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
SparseBooleanArray checked = list1.getCheckedItemPositions();
ArrayList<String> selectedItems = new ArrayList<String>();
for (int i = 0; i < checked.size(); i++) {
int position = checked.keyAt(i);
if (checked.valueAt(i))
selectedItems.add((String) adapter.getItem(position));
}
String[] valuess = new String[selectedItems.size()];
for (int i = 0; i < selectedItems.size(); i++) {
valuess[i] = selectedItems.get(i);
}
Toast.makeText(ListViewMultipleSelectionActivity.this, String.valueOf(valuess), Toast.LENGTH_SHORT).show();
}
});
this is i am getting after click

What you can do is creating a custom class to store these values along with a custom adapter that supports it. So whenever you click the button you can call the given function to retrieve the statuses of those items. Example architecture given below:
PS: Since I don't know what you want to do with checked values, I left you there with comments which you can change with your need.

Set checkbox object as tag to your row view that might be your 'convertView' in getView() method of your adapter.
Write on click listener on your row view.
3.Inside that click-listener to row view getTag from view that's parameter in onClick method and cast it to checkbox and then setChecked to true for that checkbox object.
code might look like this,
convertView.setTag(yourCheckBoxObject);
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
CheckBox cb = (CheckBox) v.getTag();
cb.setChecked(true);
}
});
Please refer this sight for more information Getting an issue while checking the dynamically generated checkbox through list view
In your Adapter there was one #override method called getView() in that method you will get the current item which you will clicked
holder.checkbox.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
CheckBox checkBox=(CheckBox) view;
String tagName="";
if(checkBox.isChecked()){
tagName=checkBox.getTag().toString();
deleteServices.add(tagName);
checkboxArrayList.add(checkBox);
}else {
checkboxArrayList.remove(checkBox);
tagName=checkBox.getTag().toString();
if(deleteServices.size()>0&&deleteServices.contains(tagName)){
deleteServices.remove(tagName);
}
});

but when I run the app, the RatingBar is untouchable, just each list of ListView is touch however I want to tap the RatingBar.
did I doing something wrong? help me please.
EDIT :
item_listview.xml
<RatingBar
android:id="#+id/rate_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/text"
android:numStars="5"
android:stepSize="1"
style="#style/Widget.AppCompat.RatingBar.Indicator" />
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold" />
the RatingBar is read-only because of the style you are using.
style="#style/Widget.AppCompat.RatingBar.Indicator"
sets the attribute android:isIndicator to true which makes behave it, in the way are experiencing. You can either get rid of the line, or try to force android:isIndicator to false in your item_listview.xml

Please help me through this I need to submit this by tomorrow.
Use this
convertView = inflater.inflate(R.layout.customlist_massage,null ,false );
Instead this
convertView = inflater.inflate(R.layout.customlist_massage,null );
Why you are extending the adapter class ArrayAdapter.
If You want to show something on listview you have to extend it to BaseAdapter OR Recyclerview Adapter.
You dont have any getCount() method in ArrayAdapter see this example::
public class Adapter extends BaseAdapter {
LayoutInflater li;
ArrayList<String> title, details;
Context con;
DataBaseHelper db;
TextView txttitle, txtdetails, txtDate;
Intent in;
public static int i = 1;
View view;
public Adapter (Context cont, ArrayList<String> news_id, ArrayList<String> news) {
this.title = news_id;
this.details = news;
this.con = cont;
li = (LayoutInflater) con.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
System.out.println("title.size() " + title.size());
return title.size();
}
#Override
public Object getItem(int arg0) {
return arg0;
}
#Override
public long getItemId(int arg0) {
return arg0;
}
#Override
public View getView(int arg0, View arg1, ViewGroup arg2) {
if (arg1 == null) {
arg1 = li.inflate(R.layout.adapter_daycare, null);
txttitle = (TextView) arg1.findViewById(R.id.title);

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)

You can always use:
yourListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
To choose multiple items, remember that its interface depend on you creating it.

Snap :
This is what it should look like.False items are checked in the snap
Above shows the full code of my project.
These are my requirements:
It is all about event planner for Food. The invited guests can select and save the interested food items such as pizza, Caesar salad, Ameretocokies etc from the items list and mail to the inviter so that the inviter can view the saved items and arrange for the selected items.
I picked the solution from Romain Guy's solution #
https://groups.google.com/forum/?fromgroups#!topic/android-developers/No0LrgJ6q2M
I have used a ViewHolder pattern for smooth scrolling and performance. I have used a SparseBooleanArray to get checked items.
I assume you want the items whose corresponding check boxes are checked.
Also check this to understand listview re-cycles views

Now 1 and 2 are checked and when you click the button at the bottom you see the selected text. I checked 1 and 2 manually. However it depends on the response ie True or False. Right now all veg items are true.
Note: The list displays only veg items
If you are using list-view and you want to check list-view item then you can use below code.
int len = mListView.getCount();
SparseBooleanArray checked = mListView.getCheckedItemPositions();
for (int i = 0; i < len; i++)
if (checked.get(i)){
..... // Your code whatever you want to do with selected item..
}
else{
....
}
Ok this is my first every android app so don't bash me. I am very open to suggestion if I am doing anything wrong or weird so please don't be shy. I'm have a little bit of trouble updating my listview after I click on an item. Anyways here's the code... I just don't understand how it works I think...
