how to add multi contact picker?

I am following this library to add contact picker https://github.com/codinguser/android_contact_picker, and I am able to get numbers successfully from adding to my EditTextBox but, I want to add multiple contacts selected from contact and add only number in particular EditTextView this is my contact picker activity, I am stuck about that where to add adapter to complete that, any help?:
public class ContactsPickerActivity extends AppCompatActivity implements OnContactSelectedListener {
public static final String SELECTED_CONTACT_ID = "contact_id";
public static final String KEY_PHONE_NUMBER = "phone_number";
public static final String KEY_CONTACT_NAME = "contact_name";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contacts);
FragmentManager fragmentManager = this.getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
ContactsListFragment fragment = new ContactsListFragment();
fragmentTransaction.replace(R.id.fragment_container, fragment);
fragmentTransaction.commit();
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setTitle("Select contact");
}
}
#Override
public void onContactNameSelected(long contactId) {
/* Now that we know which Contact was selected we can go to the details fragment */
Fragment detailsFragment = new ContactDetailsFragment();
Bundle args = new Bundle();
args.putLong(ContactsPickerActivity.SELECTED_CONTACT_ID, contactId);
detailsFragment.setArguments(args);
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack
transaction.replace(R.id.fragment_container, detailsFragment);
transaction.addToBackStack(null);
// Commit the transaction
transaction.commit();
}
/**
* Callback when the contact number is selected from the contact details view
* Sets the activity result with the contact information and finishes
*/
#Override
public void onContactNumberSelected(String contactNumber, String contactName) {
Intent intent = new Intent();
intent.putExtra(KEY_PHONE_NUMBER, contactNumber);
intent.putExtra(KEY_CONTACT_NAME, contactName);
setResult(RESULT_OK, intent);
finish();
}

Try this library https://github.com/1gravity/Android-ContactPicker it will help you to pick multiple contacts. You will get selected contacts in onActivityResult() method, from here you can display it in editText.

Calling function from a Fragment ..No activity to handle error

I saw many question related to this one but none solved my problem yet so I apologize if it was duplicated.
I'm creating a contact book. I've created a fragment to display all contacts.
Now what I want to do is to created an imageview (Call Button) to enable calling the contact when clicked.
I keep getting the error (No Activity found to handle Intent { act android.intent.action.CALL }and when I run on my device it crashed although I've added the intent to the manifest.
What am I doing wrong ?

Android Fragment initialization to various Custom Fragments, but only One at a time

I am trying to initialize a generic fragment in such manner that it can be used globally no matter what the instance of it is. For example:
public MainActivity extends Activity{
private Fragment fragment;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first_layout);
FragmentManager fragManager = getFragmentManager();
FragmentTransaction transaction = fragManager.beginTransaction();
if(condition1){
fragment = new MyFirstFragment();
transaction
.add(R.id.registrationFragment, fragment); //registrationFragment is FrameLayout
transaction.commit();
}else if(condition2){
fragment = new MySecondFragment();
transaction
.add(R.id.registrationFragment, fragment); //registrationFragment is FrameLayout
transaction.commit();
}
//create intent filter
//create MyBroadcast object
//registerReceiver(receiverObject, intentFilter)
}
//Some action happens
class MyBroadcast extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(action1)) {
fragment.performAction();
}
}
}
public class MyFirstFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(
R.layout.fragment_holder_a, container, false);
//setWidgets etc...
// TODO Auto-generated method stub
return view;
}
//Used from main
public void performAction(String text){
//set some TextView's text from MainActivity event
//different from MySecondFragment performAction method
}
}
public class MySecondFragmentFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(
R.layout.fragment_holder_b, container, false);
//setWidgets etc...
// TODO Auto-generated method stub
return view;
}
//Used from main
public void performAction(String text){
//set some TextView's text from MainActivity event
//different from MyFirstFragment performAction method
}
}
The problem is that in my real application I may have more than 2 Fragments that the Fragment object could become an instance of. I am trying to avoid a lot of if statements to check which fragment instance was inflated with the FragmentManager. Also the problem I am facing is that When i declare the Fragment fragment = new MyFirstFragment(); I cannot access the fragment.performAction("Stringssss") method. This is not the solution I am looking for:
public MainActivity extends Activity{
private MyFirstFragment myFirstFrag;
private MySecondFragment mySecondFrag;
private MyThirdFragment myThirdFrag;
private MyNthFragment myNthFrag;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first_layout);
FragmentManager fragManager = getFragmentManager();
FragmentTransaction transaction = fragManager.beginTransaction();
if(condition1){
myFirstFrag = new MyFirstFragment();
transaction
.add(R.id.registrationFragment, myFirstFrag); //registrationFragment is FrameLayout
transaction.commit();
}else if(condition2){
mySecondFrag = new MySecondFragment();
transaction
.add(R.id.registrationFragment, mySecondFrag); //registrationFragment is FrameLayout
transaction.commit();
}else if(condition3){
//...
}else if(conditionNth){
//...
}
//create intent filter
//create MyBroadcast object
//registerReceiver(receiverObject, intentFilter)
}
//Some action happens
class MyBroadcast extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(action1)) {
if(null != myFirstFrag)
myFirstFrag.performAction();
}else if(null != mySecondFrag){
mySecondFrag.performAction();
}else if(null != myThirdFrag){
myThirdFrag.performAction();
}else if(null != myNthFrag){
myNthFrag.performAction();
}
}else if(action.equals(actionNTH)){
if(null != myFirstFrag)
myFirstFrag.performAction();
}else if(null != mySecondFrag){
mySecondFrag.performAction();
}else if(null != myThirdFrag){
myThirdFrag.performAction();
}else if(null != myNthFrag){
myNthFrag.performAction();
}
}
}
}
As you can see in the BroadcastReceiver a lot of If-else statements start to pile up making the code clunky and dirty. I am looking for a clean solution that will not require me to have a bunch of if-else statements and keep the code simple.
Thank you.

Android ListFragment - onListItemClick start another fragment

Though it seems an easy problem, I've been stuck for quite a few hours. If anyone can help my out providing some code it'd be great. So there it goes my question.
There's a MainActivity which has an ActionBar with two buttons. Each button starts a ListFragment when it's clicked. Then each item of each ListFragment starts another fragment (that's what I'm not able to achieve). Here is the code for the MainActivity:
public class MainActivity extends Activity implements
DataListFragment.DataListSelectionListener {
private final String TAG = "MainActivity";
// Reference the buttons in the ActionBar
private Button actionBarData;
private Button actionBarElu;
private Button actionBarOptions;
// Reference the ListFragments
DataListFragment dataListFragment;
EluListFragment eluListFragment;
// Reference the fragments related to the listItems
SectionTypeFragment sectionTypeFragment;
SectionDimensionsFragment sectionDimensionsFragment;
MaterialsFragment materialsFragment;
ReinforcementFragment reinforcementFragment;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Inflate the custom layout for the ActionBar
final ViewGroup actionBarLayout = (ViewGroup) getLayoutInflater().inflate(
R.layout.action_bar,
null);
// Set the custom ActionBar
final ActionBar actionBar = getActionBar();
actionBar.setDisplayShowHomeEnabled(true);
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setCustomView(actionBarLayout);
// ActionBar Customization with buttons
final int actionBarColor = getResources().getColor(R.color.blue_2);
actionBar.setBackgroundDrawable(new ColorDrawable(actionBarColor));
actionBarData = (Button) findViewById(R.id.action_bar_data);
actionBarData.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View v) {
Log.i(TAG, "DATA button clicked.");
clickActionBarButton(v);
}
});
actionBarElu = (Button) findViewById(R.id.action_bar_elu);
actionBarElu.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
Log.i(TAG, "ELU button clicked.");
clickActionBarButton(v);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_bar_data) {
return true;
}
return super.onOptionsItemSelected(item);
}
public void clickActionBarButton(View v){
// Get a reference to the FragmentManager
FragmentManager fragmentManager = getFragmentManager();
// Begin a new FragmentTransaction
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
// Create the fragment depending on the button pressed
if(v == actionBarData){
// If there is no FeedFragment instance, then create one
if(sectionTypeFragment == null)
dataListFragment = new DataListFragment();
// Replace the main_frame_layout with the sectionTypeFragment
fragmentTransaction.replace(R.id.main_frame_layoout, dataListFragment);
}else if(v == actionBarElu){
// If there is no FeedFragment instance, then create one
if(sectionTypeFragment == null)
eluListFragment = new EluListFragment();
// Replace the main_frame_layout with the sectionTypeFragment
fragmentTransaction.replace(R.id.main_frame_layout, eluListFragment);
}
// Commit the FragmentTransaction
fragmentTransaction.commit();
}
// Called when the user selects an item in the DataListFragment
public void onDataListSelection(int index){
// Get a reference to the FragmentManager
FragmentManager fragmentManager = getFragmentManager();
// Begin a new FragmentTransaction
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
// Add the fragment related to the selected item in the List
switch (index){
case 0:
// If there is no SectionTypeFragment instance, then create one
if(sectionTypeFragment == null)
sectionTypeFragment = new SectionTypeFragment();
// Replace the main_frame_layout with the sectionTypeFragment
fragmentTransaction.replace(R.id.main_frame_layout, sectionTypeFragment);
// Add this FragmentTransaction to the backstack
fragmentTransaction.addToBackStack(null);
break;
case 1:
...
}
// Commit the FragmentTransaction
fragmentTransaction.commit();
}
}
Here is the code for one of the ListFragments (DataListFragment):
public class DataListFragment extends ListFragment {
private static final String TAG = "DataFragment";
// List items
private String[] listItems;
private DataListSelectionListener mListener = null;
// Callback interface that allows this Fragment to notify the MainActivity when
// user clicks on a DataList Item
public interface DataListSelectionListener {
public void onDataListSelection(int index);
}
// Called when the user selects an item from the DataList
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// Indicates the selected item has been checked
getListView().setItemChecked(position, true);
// Inform the MainActivity that an item has been selected
mListener.onDataListSelection(position);
}
public void onActivityCreated(Bundle savedInstanceState){
super.onActivityCreated(savedInstanceState);
// Get the the items to show in the List from the strings.xml
listItems = getResources().getStringArray(R.array.data_list_array);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, listItems);
setListAdapter(adapter);
}
}
Here is the exception:

how to pass the data in between activity to fragment using bundle in android

I can store the value in one variable. Now I want pass that variable into a fragment
Using the code below, I am able to load fragments:
public class AndroidListFragmentActivity extends Activity {
Fragment2 f2;
public static String itemname;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.apetiserfragement);
itemname=getIntent().getStringExtra("itemname");
Bundle args=new Bundle();
args.putString("itemname", itemname);
f2=new Fragment2();
f2.setArguments(args);
}
} /* (Here I load fragment using xml page) itemname */
The output is splitted into 2 windows one for extend for listfragment (for listview) and one for fragments.
Fragment2.xml
public class Fragment2 extends Fragment {
String itemname;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
System.out.println(getArguments().getString("itemname"));
return inflater.inflate(R.layout.fragment2, container, false);
}
#Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
}
}
AndroidListFragmentActivity in this class itemname I want pass Fragment2.class.. please help me

If both fragment are on other activity then can use intent
if on same activity then can do operation on that particular activity
as in this link
see onListItemClick of class TitlesFragment
**
* Helper function to show the details of a selected item, either by
* displaying a fragment in-place in the current UI, or starting a
* whole new activity in which it is displayed.
*/
void showDetails(int index) {
mCurCheckPosition = index;
if (mDualPane) {//<---------------------f on same activity then can do operation on that particular fragment
// We can display everything in-place with fragments, so update
// the list to highlight the selected item and show the data.
getListView().setItemChecked(index, true);
// Check what fragment is currently shown, replace if needed.
DetailsFragment details = (DetailsFragment) //<------------------------see use getFragmentManager
getFragmentManager().findFragmentById(R.id.details);
if (details == null || details.getShownIndex() != index) {
// Make new fragment to show this selection.
details = DetailsFragment.newInstance(index);
// Execute a transaction, replacing any existing fragment
// with this one inside the frame.
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.details, details);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.commit();
}
} else { //<----------If both fragment are on other activity then can use intent
// Otherwise we need to launch a new activity to display
// the dialog fragment with selected text.
Intent intent = new Intent();
intent.setClass(getActivity(), DetailsActivity.class);
intent.putExtra("index", index);
startActivity(intent);
}
