check size of image on checkbox click

I have a GridView which shows all the images from phone. I'm able to select multiple images and save the selected images to arraylist. I want to restrict the size of the selected images to 1MB. For that I want to check the size of every image while selecting. If the size of clicked image is less than 1MB then it will get selected, otherwise not. Is there any way to do that?

Get checked items id from custom listview and pass them to new activity android

I'm developing an android app which has a custom listview with a checkbox. I want to pass all the checked items from one activity to another. how should I pass them? and where should I manage the checkbox (to get all the checked items) in the custom adapter or the activity?
Note: I retrieve all the data from my server using json response.
Here's my Model :
public class Groups {
public String name;
public boolean selected= false;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public boolean isSelected() {
return selected;
}
public void setSelected(boolean selected) {
this.selected = selected;
}
public Groups() {
}
}
My Adapter:
public class AdapterMainActivity extends BaseAdapter{
Activity activity;
private LayoutInflater inflater;
List<Groups> groupsList;
public AdapterMainActivity(Activity activity, List<Groups> groupses) {
this.activity = activity;
this.groupsList = groupses;
}
#Override
public int getCount() {
return groupsList.size();
}
#Override
public Object getItem(int position) {
return groupsList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (inflater == null) {
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
if (convertView == null) {
convertView = inflater.inflate(R.layout.custom_list, null);
TextView name = (TextView) convertView.findViewById(R.id.textViewName);
final CheckBox checkBox = (CheckBox) convertView.findViewById(R.id.checkBox);
final Groups groups = groupsList.get(position);
name.setText(groupsList.get(position).getName());
checkBox.setChecked(groups.selected);
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
groups.selected = isChecked;
MainActivity.getInstance().updateArrayList(groupsList);
}
});
}
return convertView;
}
}
MainActivity:
public class MainActivity extends AppCompatActivity {
ListView listViewGroups;
Button buttonSentToActivity;
List<Groups> groupsList;
List<Groups> resultGroupList;
ArrayList<Boolean> areChecked;
List<String> finalArray;
private AdapterMainActivity adapterMainActivity;
static MainActivity yourActivity;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
yourActivity = this;
groupsList= new ArrayList<Groups>();
resultGroupList= new ArrayList<Groups>();
ReadGroup(37);
adapterMainActivity = new AdapterMainActivity(this, groupsList);
listViewGroups = (ListView) findViewById(R.id.listViewGroups);
listViewGroups.setAdapter(adapterMainActivity);
buttonSentToActivity = (Button) findViewById(R.id.buttonSendTo2Activity);
buttonSentToActivity.setOnClickListener(buttonSentToActivityListener);
Log.e("Group list size ", String.valueOf(groupsList.size()));
finalArray = new ArrayList<>();
for (int i = 0; i < resultGroupList.size(); i++) {
if (resultGroupList.get(i).selected) {
finalArray.add(resultGroupList.get(i).getName());
Log.e("final array size", String.valueOf(finalArray.size()));
}
}
}
public void ReadGroup(long cid) {
Response.Listener<String> responseListener = new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response.toString());
JSONArray readArray = jsonObject.getJSONArray("groups");
for (int i = 0; i < readArray.length(); i++) {
Log.e("i is: ", String.valueOf(i));
JSONObject jssonRow = readArray.getJSONObject(i);
String groupName = jssonRow.getString("name");
Groups groups = new Groups();
groups.setName(groupName);
Log.e("NAME is: ", groupName);
groupsList.add(groups);
}
} catch (JSONException e) {
e.printStackTrace();
}
adapterMainActivity.notifyDataSetChanged();
}
};
Log.e("Client id is: ", String.valueOf(cid));
ReadGroupRequesr readGroupRequest = new ReadGroupRequesr(cid, responseListener);
RequestQueue queue = Volley.newRequestQueue(MainActivity.this);
queue.add(readGroupRequest);
Log.e("out of the loop", "");
}
public static MainActivity getInstance() {
return yourActivity;
}
public void updateArrayList(List<Groups> arrayList) {
this.resultGroupList = arrayList;
}
View.OnClickListener buttonSentToActivityListener = new View.OnClickListener() {
#Override
public void onClick(View view) {
//Bundle b= new Bundle();
//b.putStringArrayList("arrayList", (ArrayList<String>) finalArray);
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
intent.putStringArrayListExtra("arrayList", (ArrayList<String>) finalArray);
//intent.putExtras(b);
Log.e("final array size", String.valueOf(finalArray.size()));
startActivity(intent);
}
};
}

At the very first, manage your checkboxes :
In your activity class add a boolean array or arraylist having size same as your list array size and initialize it with all value as false initially :
String[] titlesArray;
ArrayList<Boolean> arrChecked;
// initialize arrChecked boolean array and add checkbox value as false initially for each item of listview
arrChecked = new ArrayList<Boolean>();
for (int i = 0; i < titles.size(); i++) {
arrChecked.add(false);
}
Now replace your adapter class with this :
class VivzAdapter extends ArrayAdapter<String> implements OnCheckedChangeListener {
Context context;
int[] images;
String[] titlesArray, descrptionArray;
List<Integer> positions = new ArrayList<Integer>();
ArrayList<Boolean> arrChecked;
VivzAdapter(Context context, String[] titles, int[] images, String[] description, ArrayList<Boolean> arrChecked) {
super(context, R.layout.single_row, R.id.textView1, titles);
this.context = context;
this.images = images;
this.titlesArray = titles;
this.descrptionArray = description;
this.arrChecked = arrChecked;
}
class MyViewHolder {
ImageView myImage;
TextView myTitle;
TextView myDescription;
CheckBox box;
MyViewHolder(View v) {
myImage = (ImageView) v.findViewById(R.id.imageView1);
myTitle = (TextView) v.findViewById(R.id.textView1);
myDescription = (TextView) v.findViewById(R.id.textView2);
box = (CheckBox) v.findViewById(R.id.checkBox1);
}
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
MyViewHolder holder = null;
if (row == null) {
// 1.ºtime
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//row contem RelativeLayout(root) em single_row.xml
row = inflater.inflate(R.layout.single_row, parent, false);
holder = new MyViewHolder(row);
row.setTag(holder);
//Log.d("VIVZ", "Creating a new Row");
} else {
//reciclamos aqui, qeremos usar antigo objecto holder
holder = (MyViewHolder) row.getTag();
//Log.d("VIVZ", "Recycling stuff");
}
holder.myImage.setImageResource(images[position]);
holder.myTitle.setText(titlesArray[position]);
holder.myDescription.setText(descrptionArray[position]);
//set position as id
holder.box.setId(position);
//set onClickListener of checkbox rather than onCheckedChangeListener
holder.box.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
int id = v.getId();
if (arrChecked.get(id)) {
//if checked, make it unchecked
arrChecked.set(id, false);
} else {
//if unchecked, make it checked
arrChecked.set(id, true);
}
}
});
//set the value of each checkbox from arrChecked boolean array
holder.box.setChecked(arrChecked.get(position));
return row;
}
}
After that, implement click listener of send button say btnSend button (I am considering that you are sending your data from one activity to another activity on click of send button) :
btnSend.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ArrayList<String> arrTempList = new ArrayList();
for(int i=0; i<titles.size(); i++){
if(arrChecked.get(i) == true){
arrTempList.add(titles[i]);
}
}
// here you can send your arrTempList which is having checked items only
}
});

Here's the solution for this Question:
My adapter:
public class ChooseContactsAdapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
public ArrayList<Contacts> contactsList;
public CheckBox checkBoxAdapter;
public ChooseContactsAdapter(Activity activity, ArrayList<Contacts> group) {
this.activity = activity;
this.contactsList = group;
}
#Override
public int getCount() {
return contactsList.size();
}
#Override
public Object getItem(int position) {
return contactsList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null) {
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
if (convertView == null) {
convertView = inflater.inflate(R.layout.custom_choose_contacts_sms,
null);
final TextView fNAme = (TextView) convertView.findViewById(R.id.textViewCustomSMSSelectContactFName);
TextView LName = (TextView) convertView.findViewById(R.id.textViewCustomSMSSelectContactLName);
checkBoxAdapter = (CheckBox) convertView.findViewById(R.id.checkBoxSelectContact);
checkBoxAdapter.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
CheckBox cb = (CheckBox) view;
Contacts contacts = (Contacts) cb.getTag();
contacts.setSelected(cb.isChecked());
Toast.makeText(activity.getApplicationContext(),
"Clicked on Checkbox: " + cb.getText() +
" is " + cb.isChecked(),
Toast.LENGTH_LONG).show();
}
});
final Contacts contacts = contactsList.get(position);
fNAme.setText(contacts.getContactFName());
LName.setText(contacts.getContactLName());
checkBoxAdapter.setChecked(contacts.isSelected());
checkBoxAdapter.setTag(contacts);
}
return convertView;
}
}
In my activity I have button to go from 1 activity to the 2 activity:
private View.OnClickListener buttonSubmitGroupListener =new View.OnClickListener() {
#Override
public void onClick(View view) {
List <Integer> contactsIDArray= new ArrayList<Integer>();
List<Contacts> arrayOfContacts= chooseContactsAdapter.contactsList;
for(int i=0; i< arrayOfContacts.size(); i++){
Contacts contacts= arrayOfContacts.get(i);
if(contacts.isSelected()==true){
contactsIDArray.add(contacts.getContactID());
}
}
for (int i = 0; i < contactsIDArray.size(); i++) {
Log.e("Id Array size ", String.valueOf(contactsIDArray.size()));
Log.e("Selected id ", String.valueOf(contactsIDArray.get(i)));
}
intent = new Intent(getApplicationContext(), SendSMSActivity.class);
Bundle b = new Bundle();
b.putIntegerArrayList("checkedContacts", (ArrayList<Integer>) contactsIDArray);
intent.putExtras(b);
startActivity(intent);
}
};
Second Activity add this code:
Bundle b = getIntent().getExtras();
List<Integer> result = new ArrayList<Integer>();
result = b.getIntegerArrayList("checkedContacts");

Deleting listview item from database

I am deleting the title 2 list item item
But the last title gets deleted that is the title 8 gets deleted
When I then go back to the previous screen and reopen the list. The correct that is the 2nd item title 2 had been deleted.

holder.idTextview = (TextView) convertView.findViewById(R.id.idlist);
holder.deleteButton = (Button) convertView.findViewById(R.id.deletelist);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.dateTextView.setText(calendars.get_reminderdate());
holder.timeTextView.setText(calendars.get_remindertime());
holder.titleTextView.setText(calendars.get_remindertitle());
holder.idTextview.setText(calendars.get_id() + "");
holder.deleteButton.setTag(calendars);
holder.deleteButton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
AlertDialog.Builder adb = new AlertDialog.Builder(v.getRootView().getContext());
adb.setTitle("Delete");
adb.setMessage("Are you sure you want to delete this reminder?");
//final int positionToRemove = view.getId();
adb.setNegativeButton("Cancel", null);
adb.setPositiveButton("Ok", new AlertDialog.OnClickListener()
{

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
