Listview custom adapter cant select an item

I tried all the solution that i found here in the stackoverflow but it seems like none of them work.
Here is my main activity:
public class MerchantLocatorActivity extends AppCompatActivity implements OnMapReadyCallback {
public void init(){
merchantLocatorResponseObject = new MerchantLocatorResponse();
merchantLocatorResponseObject.setTitle("Spherical");
merchantLocatorResponseObject.setAddress("8007 Pioneer St, Kapitolyo, Mandaluyong, 1550 Metro Manila");
merchantLocatorResponseObject.setLatitude( 14.573249);
merchantLocatorResponseObject.setLongitude(121.057022);
merchantLocatorObjectArray.add(merchantLocatorResponseObject);
merchantLocatorResponseObject = new MerchantLocatorResponse();
merchantLocatorResponseObject.setTitle("Globe");
merchantLocatorResponseObject.setAddress("SCT, 584 Shaw Blvd, Mandaluyong, 1552 Metro Manila");
merchantLocatorResponseObject.setLatitude(14.585095);
merchantLocatorResponseObject.setLongitude(121.048893);
merchantLocatorObjectArray.add(merchantLocatorResponseObject);
merchantLocatorResponseObject = new MerchantLocatorResponse();
merchantLocatorResponseObject.setTitle("Sparndium");
merchantLocatorResponseObject.setAddress("Xavier, San Juan, 1502 Metro Manila");
merchantLocatorResponseObject.setLatitude(14.601918);
merchantLocatorResponseObject.setLongitude(121.042169);
merchantLocatorObjectArray.add(merchantLocatorResponseObject);
addMarker();
}
#OnClick(R.id.fab)
public void showAccToDialog() {
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
View alertView = LayoutInflater.from(this).inflate(R.layout.dialog_biller, null);
alertDialogBuilder.setView(alertView);
final AlertDialog dialog = alertDialogBuilder.create();
dialog.show();
final ListView listViewBillers = (ListView) dialog.findViewById(R.id.biller_institutions_listview);
if (listViewBillers != null) {
MerchantLocatorAdapter adapter = new MerchantLocatorAdapter(
this, R.layout.merchant_locator_adapter, merchantLocatorObjectArray);
listViewBillers.setAdapter(adapter);
listViewBillers.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
geoLocate(merchantLocatorObjectArray,position);
DebugUtils.log("TESTTESTACTIVITYZXC");
DebugUtils.showToast(MerchantLocatorActivity.this,"HAHAHAH");
dialog.dismiss();
}
});
final EditText mSearchedittext = (EditText) dialog.findViewById(R.id.search_edittext);
mSearchedittext.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
final ArrayList<MerchantLocatorResponse> searchResultObject = new ArrayList<>();
searchResultObject.clear();
for (int hay = 0; hay <= merchantLocatorObjectArray.size() - 1; hay++) {
if ( merchantLocatorObjectArray.get(hay).getTitle().toLowerCase().contains(charSequence)) {
searchResultObject.add( merchantLocatorObjectArray.get(hay));
}
}
MerchantLocatorAdapter adapter = new MerchantLocatorAdapter(
MerchantLocatorActivity.this, R.layout.merchant_locator_adapter, searchResultObject);
listViewBillers.setAdapter(adapter);
listViewBillers.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long arg) {
geoLocate(searchResultObject,position);
dialog.dismiss();
}
});
}
#Override
public void afterTextChanged(Editable editable) {
}
});
}
}
}
i remove some part of the code because i think it's un necessary to include but let me know if there's some part that i need some clarification.
currently in my main activity, i'm calling a dialog that contains a listview and in my listview i have items.
My problem is i can't select any of my items even thought i have my setOnitemclick listener.
here is my adapter:
public class MerchantLocatorAdapter extends BaseAdapter {
private int resourceLayout;
private Context mContext;
ArrayList<MerchantLocatorResponse> merchantLocatorarray = new ArrayList<>();
public MerchantLocatorAdapter(Context context, int resource, ArrayList<MerchantLocatorResponse> merchantLocatorResponsesobjectArray) {
this.resourceLayout = resource;
this.mContext = context;
this.merchantLocatorarray = merchantLocatorResponsesobjectArray;
}
#Override
public int getCount() {
return merchantLocatorarray.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(mContext.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(resourceLayout, parent, false);
}
TextView tt1 = (TextView) convertView.findViewById(R.id.field_name_textview);
TextView tt2 = (TextView) convertView.findViewById(R.id.field_value_textview);
ImageButton direction = (ImageButton) convertView.findViewById(R.id.direction);
tt1.setText(merchantLocatorarray.get(position).getTitle());
tt2.setText(merchantLocatorarray.get(position).getAddress());
return convertView;
}
}
here is my layout for my adapter:

i tried every solution that i found here in stackoverflow, and yet i can't still click my item. so please don't mark this as a duplicate.
if there's any part of the code that need clarification, please leave a comment and i'll answer as soon as possible. thanks.

Try to use Observable in you custom adapter:
// Define
private final PublishSubject<MerchantLocatorResponse> onItemClick = PublishSubject.create();
// Create the observable method
public Observable<ConversationMessage> getObservable(){
return onItemClick;
}
// Set the onClickListener into getView()
convertView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onItemClick.onNext(merchantLocatorarray.get(position));
}
});
Then, in your main activity listen to it and handle the click:
#OnClick(R.id.fab)
public void showAccToDialog() {
// bla bla bla
listViewBillers.setAdapter(adapter);
listViewBillers.getObservable().subscribe(geoLocate);
// bla bla bla
}
Consumer<MerchantLocatorResponse> geoLocate = new Consumer<MerchantLocatorResponse>() {
#Override
public void accept(MerchantLocatorResponse mlr) {
// Code after click event
}
};
Add those library in your gradle:
implementation "io.reactivex.rxjava2:rxjava:2.1.5"
implementation "io.reactivex.rxjava2:rxandroid:2.0.1"

Add convertView.setOnclickListener() in your code. Try below code in your adapter
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(mContext.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(resourceLayout, parent, false);
}
TextView tt1 = (TextView) convertView.findViewById(R.id.field_name_textview);
TextView tt2 = (TextView) convertView.findViewById(R.id.field_value_textview);
ImageButton direction = (ImageButton) convertView.findViewById(R.id.direction);
tt1.setText(merchantLocatorarray.get(position).getTitle());
tt2.setText(merchantLocatorarray.get(position).getAddress());
convertView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context, String.valueOf(position), Toast.LENGTH_SHORT).show();
}
});
return convertView;
} }

Call contacts from a list in Android Studio

I have an Android application where I used Linear Layout that shows a list of contacts. Now what I want is that when selecting the contacts, call the indicated number.
For now, all it do is show the contacts, but when I click on call, it does not take any action. I do not know how to make to mark
I tried with setOnClickListener().But Unsuccessful
My code:
public class ContactsAdapter extends RecyclerView.Adapter<ContactsAdapter.ContactViewHolder>{
Dialog myDialog;
private List<ContactModel> contactModelList;
private Context mContext;
public ContactsAdapter(List<ContactModel> contactModelList, Context mContext){
this.contactModelList = contactModelList;
this.mContext = mContext;
}
#Override
public ContactViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(mContext).inflate(R.layout.single_contact_view, null);
ContactViewHolder contactViewHolder = new ContactViewHolder(view);
return contactViewHolder;
}
#Override
public void onBindViewHolder(ContactViewHolder holder, int position) {
final ContactModel contactModel = contactModelList.get(position);
holder.tvContactName.setText(contactModel.getContactName());
holder.tvPhoneNumber.setText(contactModel.getContactNumber());
holder.contactsRowLV.setOnClickListener(
new View.OnClickListener()
{
#Override
public void onClick(View view) {
Toast.makeText(mContext,""+ contactModel.getContactNumber(),Toast.LENGTH_SHORT).show();
}
});
}
#Override
public int getItemCount() {
return contactModelList.size();
}
public static class ContactViewHolder extends RecyclerView.ViewHolder{
ImageView ivContactImage;
TextView tvContactName;
TextView tvPhoneNumber;
LinearLayout contactsRowLV;
public ContactViewHolder(View itemView) {
super(itemView);
ivContactImage = (ImageView) itemView.findViewById(R.id.ivContactImage);
tvContactName = (TextView) itemView.findViewById(R.id.tvContactName);
tvPhoneNumber = (TextView) itemView.findViewById(R.id.tvPhoneNumber);
contactsRowLV = itemView.findViewById(R.id.contactsRowLV);
}
}
}
Here I show my XML of how I have. Help me please
<LinearLayout
android:id="#+id/contactsRowLV"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/ivContactImage"
android:layout_width="55dp"
android:layout_height="55dp"
android:layout_marginLeft="10dp"
android:layout_marginStart="10dp"
android:layout_gravity="center"
android:src="#drawable/ic_person"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center_vertical">
<TextView
android:id="#+id/tvContactName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginStart="10dp"
android:textSize="30dp"
android:textStyle="bold"
android:textColor="#android:color/primary_text_light"
android:text="Name"/>
<TextView
android:id="#+id/tvPhoneNumber"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginStart="10dp"
android:textSize="25dp"
android:textColor="#android:color/primary_text_light"
android:text="Phone"/>
</LinearLayout>
</LinearLayout>

You just need to add following code in setOnClickListener(). This code is used to call particular number.
#Override
public void onBindViewHolder(ContactViewHolder holder, int position) {
final ContactModel contactModel = contactModelList.get(position);
holder.tvContactName.setText(contactModel.getContactName());
holder.tvPhoneNumber.setText(contactModel.getContactNumber());
holder.contactsRowLV.setOnClickListener(
new View.OnClickListener(){
#Override
public void onClick(View view) {
Toast.makeText(mContext,""+ contactModel.getContactNumber(),Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:" +contactModel.getContactNumber()));
mContext.startActivity(intent);
}
});
}

How to add items to recyclerview programmatically? [duplicate]

I have a button(save contact) to save contacts ,the button when pressed get name and email from edit text and should dynamically add 1 list item in recycle view
The save button is in fragment
This is the name which i am extracting
company_name=(EditText)view.findViewById(R.id.edittext_companyname_createMeeting);
When i click on lead it should add in the existing recycleview
leads.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
newValueAdapter.newAddeddata(company_name.getText().toString());*/
}
});
The recycle view already have a arraylist,how do i add new value to the arraylist and again call oncreate
I tried to extract company name and send it to the adapter of that recycler view but it dint work

cold.setBackground(getResources().getDrawable(R.drawable.bordder_button));
}
}

Add this method to your adapter and call on button click.
public void newAddeddata(String company_name){
NewleadsPOJO newValue=new NewleadsPOJO();
newValue.setLeads_company(company_name);
datalist.add(newValue);
notifyDataSetChanged();
}
Add following method to NewLeadFrag
public NewleadsAdapter getAdapter(){
return adapter;
}
now in Createmeetingfrag
leads.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
NewLeadFrag fragment = getFragmentManager().findFragmentByTag("NewLeadFrag_TAG"); //set tag of fragment when you add with fragment manager. and if you are using support library use getSupportFragmentManager()
if(fragment!= null){
fragment.getAdapter().newAddeddata(company_name.getText().toString());
}
}
});

You don't need to go through the entire life cycle of your Activity or Fragment just because you've made changes to the list. Instead try adding the item in the list you currently have associated with the Adapter. And then call adapter.notifyDataSetChange(). This should automatically add the new Item to the RecyclerView.

How to box each word after user presses space/comma in android studio?

I'm currently trying to make an android application and I've run into a problem. How would you allow for user to type a word and once they press space/comma, it boxes the word, preferably with an exit option.

Anything along the lines of these pictures would be perfect.

What you are wanting is called chips in Android, it's one of the native designs you can read about it's specification here.
Here are a few example to get you started, last time I checked there was no proper documentation or support for this feature so I ended up using one the libraries that has built it, you can do something yourself by implementing a custom view as explained here

Here is how I would implement it. This is a working example. When the user hits space it adds and item. When you click an item it will remove it.
Here is a gif of it in action.

AnimateLayoutChanges doesn't work with RecyclerView

I have a screen with a Recyclerview and others Elements inside of LinearLayout. The problem is when I remove a item of the RecyclerView, animateLayoutChanges doesn't work in this case. Does anayone know why this happen??

public class MainActivity extends AppCompatActivity {
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
Adapter adapter = new Adapter();
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(adapter);
recyclerView.setNestedScrollingEnabled(true);

class Adapter extends RecyclerView.Adapter<Adapter.Holder>{
int size = 3;
public Adapter() {
}
#Override

View view = getLayoutInflater().inflate(R.layout.item, parent, false);
return new Holder(view);
}

super(itemView);
itemView.setOnClickListener(new View.OnClickListener() {
#Override

notifyItemRemoved(getAdapterPosition());
}
});
}
}
}

After a while I got a solution. I made a function to animate the recyclerView height.
JAVA
public class MainActivity extends AppCompatActivity {
private final String TAG = MainActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
Adapter adapter = new Adapter(recyclerView);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this) {
#Override
public boolean canScrollVertically() {
return false;
}
};
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setAdapter(adapter);
recyclerView.setNestedScrollingEnabled(true);
View.OnClickListener listener = new View.OnClickListener() {
#Override
public void onClick(View view) {
view.setVisibility(View.GONE);
}
};
findViewById(R.id.test1).setOnClickListener(listener);
findViewById(R.id.test2).setOnClickListener(listener);
findViewById(R.id.test3).setOnClickListener(listener);
findViewById(R.id.test4).setOnClickListener(listener);
}
public void animateHeight(final View v, final int height) {
final int initialHeight = v.getMeasuredHeight();
int duration = 500;
Interpolator interpolator = new AccelerateInterpolator(2);
// I have to set the same height before the animation because there is a glitch
// in the beginning of the animation
v.getLayoutParams().height = initialHeight;
v.requestLayout();
Animation a = new Animation() {
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
Log.d(TAG, "InterpolatedTime: " + interpolatedTime);
Log.d(TAG, "Collapsing height: " + (initialHeight - (int) (height * interpolatedTime)));
v.getLayoutParams().height = initialHeight - (int) (height * interpolatedTime);
v.requestLayout();
}
#Override
public boolean willChangeBounds() {
return true;
}
};
a.setDuration(duration);
a.setInterpolator(interpolator);
v.startAnimation(a);
}
class Adapter extends RecyclerView.Adapter<Adapter.Holder> {
RecyclerView mRecyclerView;
int size = 3;
public Adapter(RecyclerView recyclerView) {
mRecyclerView = recyclerView;
}
#Override
public Holder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = getLayoutInflater().inflate(R.layout.item, parent, false);
return new Holder(view);
}
#Override
public void onBindViewHolder(Holder holder, int position) {
}
#Override
public int getItemCount() {
return size;
}
class Holder extends RecyclerView.ViewHolder {
public Holder(final View itemView) {
super(itemView);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
size--;
notifyItemRemoved(getAdapterPosition());
animateHeight((View) itemView.getParent(), itemView.getMeasuredHeight());
}
});
}
}
}
}

What worked for me was simply adding the following code to onCreate:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
((ViewGroup) findViewById(R.id.llRoot)).getLayoutTransition()
.enableTransitionType(LayoutTransition.CHANGING);
}
where llRoot is your LinearLayout containing RecyclerView.
You do need to keep android:animateLayoutChanges="true" on your LinearLayout, otherwise it crashes.
I believe if you want to support this below JellyBean, you would need your custom solution.
Explanation on the solution is here: https://proandroiddev.com/the-little-secret-of-android-animatelayoutchanges-e4caab2fddec
