Assinging the values of cursor to object

Assinging the values of cursor to object - android

I'm working on showing list of contacts with checkbox. I tried implementing my own cursor adapter and it is checkable. But once I check that value I want the contacts to be stored in ContactPerson object. But when I tried it is showing null pointer exception(That's why I commented out that code). My CursorAdapter code goes like this.
ContactListAcitivity.java
import android.app.Activity;
import android.content.Context;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.support.v4.widget.CursorAdapter;

public class ContactListActivity extends Activity {
ListView list;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contact_list);
list = (ListView) findViewById(R.id.ListView2);
Cursor cur= getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null,null,null,null);
startManagingCursor(cur);
String[] result=new String[cur.getCount()];
for (boolean hasData = cur.moveToFirst(); hasData; hasData = cur.moveToNext())
{
ContactPerson contact = new ContactPerson(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)), String.valueOf(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
}
stopManagingCursor(cur);
list.setAdapter(new contactAdapter(getApplicationContext(), cur));
}

Can anyone please suggest me how to use that Contact person class in this adapter.
public class ContactPerson {
String name= null, number = null;
boolean Selected = false;
public ContactPerson(String PersonName, String PhoneNumber){
this.name = PersonName;
this.number= PhoneNumber;
}
public String getName(){
return name;
}
public boolean isSelected(){
return Selected;
}
public void setSelected(boolean selected){
this.Selected = selected;
}
public String getPhoneNumber(){
return number;
}
}

Check this code. It worked for me. Best of luck.

Here i changed little bit code of your adapter and activity. just look at it:
public class MainActivity extends Activity {
private ArrayList<ContactPerson> arr;

public static boolean[] arrBoolean = null;
#Override
public void onCreate(Bundle savedInstance) {
super.onCreate(savedInstance);
setContentView(R.layout.activity_main);
ProgressDialog pd = new ProgressDialog(this);
list = (ListView)findViewById(R.id.ListView2);
arr = new ArrayList<ContactPerson>();
context = MainActivity.this;
arr = displayContacts();
adapter = new ContactArrayAdapter(this, R.layout.checkbox_item, arr);
list.setAdapter(adapter);
}
public ArrayList<ContactPerson> displayContacts() {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
ContactPerson contact;
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
contact = new ContactPerson();
String id = cur.getString(cur.getColumnIndex(People._ID));
String name = cur.getString(cur.getColumnIndex(People.DISPLAY_NAME));
ContactPerson cp = new ContactPerson();
cp.setName(name);
cp.setNumber(id);
cp.setSelected(false);
arr.add(cp);
}
}
return arr;
}
//********* Adapter *****
public class ContactArrayAdapter extends ArrayAdapter<ContactPerson> {

super(context, textViewResourceId, stateList);
this.list = new ArrayList<ContactPerson>();
this.list.addAll(stateList);

Change this line

to this
Resources resources = getResources();
holder.wish_list.setImageDrawable(resources.getDrawable(R.drawable.wishlist));
and do the same in else part and check the output..
Note :
getResources().getDrawable is deprecated.
You can try ContextCompat.getDrawable:
holder.wish_list.setImageDrawable(ContextCompat.getDrawable(context,
R.drawable.wishlist));
UpDate :
check this way.
if(state == true){
// here is default icon and set api value and send it

contact on list view with select all option and search option on android

contact on list view with select all option and search option on android
i have tried a lot of ways but no matter to find a list view with name,phone no and check box for everyone and also a select all button and search option
public void onTextChanged(CharSequence s,int start, int before, int count)
{
textlength = et.getText().length();
// et.setText(textlength);
if(et.getText().toString().equalsIgnoreCase("helloo")){
// Toast.makeText(getApplicationContext(),"jd",1000).show();
for (int i = 0; i < name1.size(); i++)
{
if (textlength <= name1.size())
{
Toast.makeText(getApplicationContext(),"searching.....inside",1000).show();
if(et.getText().toString().equalsIgnoreCase((String)((CharSequence) name1).subSequence(0,textlength)))
{
// array_sort.addAll(name1);
}
}
if(et.getText().toString().equalsIgnoreCase(
(String)(CharSequence) name1)){
Toast.makeText(getApplicationContext(),"searching.....",1000).show();
}
}
lv.setAdapter(new ArrayAdapter<String>
(contact_fetch.this,
android.R.layout.simple_list_item_1, array_sort));
}
}
});

I had the same problem.Finally I solved with this code. Hope It will help you :)
//layout function
public void lay_out(List<String> exp1,int k){
LayoutInflater layoutInflater =
(LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
container.removeAllViews();

final View addView = layoutInflater.inflate(R.layout.row, null);
TextView tv=(TextView)addView.findViewById(R.id.textView1);
final CheckBox cb=(CheckBox) addView.findViewById(R.id.checkbox1);
if(k==0)
{
cb.setChecked(false);
}
else
{
cb.setChecked(true);
}
tv.setText(name1.get(i));
cb.setText(phno1.get(i));
container.addView(addView);
cb.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
// Toast.makeText(getApplicationContext(),cb.getText().toString(),10).show();
if(cb.isChecked()==true){
if(checkedcontacts.length()<0)
{
for(int i=0;i<=checkedcontacts.length();i++)
{
if(!checkedcontacts.equals(cb.getText().toString()))
{
// insertion
checkedcontacts.append(cb.getText().toString());
checkedcontacts.append("\n");
}
}
}
else{
checkedcontacts.append(cb.getText().toString());
checkedcontacts.append("\n");
}
}
else if(cb.isChecked()==false){
s_all.setChecked(false);
try{
Toast.makeText(getApplicationContext(),cb.getText().toString(),10).show();
//Pattern.compile(cb.getText().toString()).matcher(checkedcontacts).replaceAll("");
checkedcontacts.delete(checkedcontacts.indexOf(cb.getText().toString()),
cb.getText().toString().length());
}
catch(Exception e){
System.out.println("error on array"+e);
}
}
}
});
container.setVisibility(View.VISIBLE);
}

You can always use:
yourListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
To choose multiple items, remember that its interface depend on you creating it.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true"

<item
android:drawable="#color/list_bg" />
</selector>

Not able to see text in ListView

I am using ListActivity to display simple text with SimpleCursorAdapter to get the texts from my database. I have tried to debug the problem and found that the cursor is successfully fetching the result but the text is not displayed in the ListView.
Following is the ListActivity code I am using.
public class MyListActivity extends ListActivity{
Cursor myCursor;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
myCursor = getData();
startManagingCursor(myCursor);
ListAdapter myAdapter = new SimpleCursorAdapter(this, R.layout.display_details, myCursor, new String[]{MyDbHelper.ID_FIELD, MyDbHelper.NAME_FIELD}, new int[]{R.id.row_id, R.id.row_name});
setListAdapter(myAdapter);
}
private Cursor getData() {
return MyDBHelper.getRoutes();
}
#Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
routesCursor.close();
}
}
and following is my xml file for each row in ListView
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/row_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/row_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/row_id"
android:layout_toRightOf="#+id/row_id"
android:textAppearance="?android:attr/textAppearanceLarge" />
</RelativeLayout>
and my layout for ListActivity is as following
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView android:id="#+id/list" android:layout_width="fill_parent" android:layout_height="fill_parent">
</ListView>
</RelativeLayout>
Please provide me the solution. Thanks in advance.

Android: ListView making a search Filter

Is there a way to create a search filter over my custom list view which created using BaseAdapter rather than ArrayAdapter, because I have only come across methods that are using ArrayAdapters in there Custom List Views. Follwing is what I have come acrossMaking a filter using Array Adapter

If you're using List collection then extend ArrayAdapter - it's subclass of BaseAdapter.
Override getView method (In your case just copy your old getView code with little modifications).
Override toString of object that is in your collection and set:
listView.setTextFilterEnabled(true);

Here is an example for list view created using base adapter.
I searched a lot but didn't get any satisfactorily solution.Hence I thought to put it up so that in future it might help others.
Here is the code of history_container.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical">
<EditText android:layout_width="fill_parent" android:layout_height="wrap_content"
android:id="#+id/filter_text" />
<FrameLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="#+id/historyContainerLayout" />
</LinearLayout>
Here is the code of history_list_view.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content" android:gravity="left|center"
android:layout_width="wrap_content" android:paddingBottom="5px"
android:paddingTop="5px" android:paddingLeft="5px">
<TextView android:text="#+id/historytext" android:id="#+id/historytext"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_marginLeft="10px" android:textColor="#0099CC"/>
</LinearLayout>
Here is the code of history_schedule.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ScrollView android:id="#+id/scrollItemInfo"
android:layout_width="fill_parent" android:layout_height="1000dip">
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<ListView android:id="#+id/historylist" android:layout_height="1000dip"
android:layout_width="fill_parent"/>
</LinearLayout>
</ScrollView>
</LinearLayout>
Sorry, I am not being able to put the code in correct format.Seems something has changed as there is no tag anymore which was nice.But for user convenience this is also a good idea to have tab.
Maybe it is my fault that I'm not being able to post in correct format.And seems like we cannot post xml file content..So, think how the layout would have designed.
The activity code is :-

ArrayAdapter is a child class of BaseAdapter.
Source code for ArrayAdapter is here. Take a look at it..
This should solve your problem.

Here is an example . Edit and use what you need.
public class CustomListAdapter extends BaseAdapter {
private ArrayList<String> countryStringList;
private ArrayList<Integer> countryImageList;
private LayoutInflater mInFlater;
// private Bitmap mIcon1;
// private Bitmap mIcon2;
private int layoutID;
private Context context;
// private LayoutInflater mInflater;
public CustomListAdapter(Context context, int textViewResourceId,
ArrayList<String> stringObjects, ArrayList<Integer> imgObjects) {
super();
this.context = context;
countryStringList = stringObjects;
countryImageList = imgObjects;
layoutID = textViewResourceId;
mInFlater = LayoutInflater.from(context);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
// return countryStringList.size();
return countryStringList.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
final ViewHolder holder;
if (convertView == null) {
convertView = mInFlater.inflate(layoutID, null);
holder = new ViewHolder();
holder.textCountryName = (TextView) convertView
.findViewById(R.id.txtSelectedCountryName);
holder.icon = (ImageView) convertView
.findViewById(R.id.imgSelectedCountryImage);
holder.textCountryPosition = (TextView) convertView
.findViewById(R.id.txtSelectedCountryPosition);
// holder.checkBoxListView=(CheckBox)convertView.findViewById(R.id.CheckBoxListView);
holder.relativeLayoutList = (RelativeLayout) convertView
.findViewById(R.id.relativeLayoutListItem);
holder.checkBoxListView = (CheckBox) convertView
.findViewById(R.id.checkBoxSelectedCountry);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
// holder=(ViewHolder)convertView.findViewById(R.id.TextViewIcon1)
}
holder.checkBoxListView.setTag(position);
holder.textCountryName.setText(countryStringList.get(position));
holder.textCountryPosition.setText(position + 1 + "/"
+ countryStringList.size());
holder.icon.setImageResource((countryImageList.get(position)));
if (ListViewController.checkStatusList.get(position).equalsIgnoreCase("present")) {
holder.checkBoxListView.setVisibility(View.VISIBLE);
} else {
holder.checkBoxListView.setVisibility(View.GONE);
}
/*
