Buttons for ListView Not Showing

Buttons for ListView Not Showing - android

please can you help me with the following issue. I’m trying to develop a contact directory as part of my app which allows the user to click a call and email button next to each contact and perform the relevant action. The directory displays fine however:
1) The call and email buttons in the phonebook_row.xml class are not being displayed when I run the app. How can I fix this issue?
2) How can I make the call and email clickable buttons which take just the phone number and email (without ‘Name:’ and ‘Email’) from the strings it is stored next to and open the number in phone dialler/create new email with email address?
My code is as follows…
Directory.java:
import android.graphics.Bitmap;
public class Directory {
private Bitmap mAvatar;
private String mName;
private String mPhone;
private String mEmail;
private String mLocation;
public Directory(Bitmap mAvatar, String mName, String mPhone, String mEmail, String mLocation) {
this.mAvatar = mAvatar;
this.mName = "Name: " + mName;
this.mPhone = "Phone Extension: " + mPhone;
this.mEmail = "Email: " + mEmail;
this.mLocation = "Location: " + mLocation;
}
public Bitmap getmAvatar() {
return mAvatar;
}
public void setmAvatar(Bitmap mAvatar) {
this.mAvatar = mAvatar;
}
public String getmName() {
return mName;
}
public void setmName(String mName) {
this.mName = mName;
}
public String getmPhone() {
return mPhone;
}
public void setmPhone(String mPhone) {
this.mPhone = mPhone;
}
public String getmEmail() {
return mEmail;
}
public void setmEmail(String mEmail) {
this.mEmail = mEmail;
}
public String getmLocation() {
return mLocation;
}
public void setmLocation(String mLocation) {
this.mLocation = mLocation;
}
}

In the get view method of your adapter class you can do the following, notice I use an imageview in the example and its only for the calling part. A button would have the same implementation.
ImageView icon = (ImageView)view.findViewById(R.id.callicon);
icon.setImageResource(R.drawable.ic_action_call);
icon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//----create new intent for the call action and give it the number
//this will just start the dailer but not complete the action
Intent callIntent = new Intent(Intent.ACTION_DIAL,
Uri.parse("tel:" + entry.getmPhone()));
callIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(callIntent);
}
});

Please Try to start listening for Firebase data before setting the adapter, so
replace
findFriendList.setAdapter(firebaseRecyclerAdapter);
firebaseRecyclerAdapter.startListening();
with
firebaseRecyclerAdapter.startListening();
findFriendList.setAdapter(firebaseRecyclerAdapter);
in your onStart() method.

Run-time Expandable Listview with Edittext and Spinner

My intention is to get data from the run-time growing listview (as shown in below figures) which has Edittext and Spinners and send this data to remote server using json.
Am I on the correct path or there is another kind of method to be used for this.
I want to access Edittext and Spinner from the listview which is expanded at runtime.
My Problem is, whenever a new view is added, it overlaps on the previous view.
Instead, it should get added below the 1st view. (Solved this. See the edited code).
Another thing is how to access edittext & spinner from each view? I want to accept this data from user & save it in the device. How to do that? (in private void SaveUserData() {} method).
Below is my full code.

Your listview needs a height, it cannot be wrap_content. Give it a height like 500dp or match_parent.

Replace the below
InviteUsersListRow rowUser = new InviteUsersListRow(R.id.profileImage, R.id.imageButtonInviteUser, name, mobile);
with
InviteUsersListRow rowUser = new InviteUsersListRow(R.drawable.camera, R.drawable.add_user_50, name, mobile);
The pic should be from "R.drawable" not from "R.id"
You should actually set an image resource below and not an id
holder.imageView.setImageResource(rowItem.getImageId());
holder.imgStatus.setImageResource(rowItem.getImageStatus());
In the above code you are not setting a drawable item.

ListFragment and Custom Adapter Issue

Two issue with List Fragment: 1. I have a class that extends ListFragments.In the onCreated, I am setting my custom Adapter. The issue is that when the user logs in, the adadpter is null and would not have a value until the user searches for an owner. As a result, it throws an exception when it tries to set up the listadapter and it finds the ArrayAdapter object to be null. I have a custome layout that has a listview and a textview, but I still gets the error. See sample code below. I bold the line of code where the issue happens. Also, I bold few other section where I think it may be important to notice.
I implemented Parcelable in the class "Owner" so that I can pass the object as a ParcelableArray. Even though the object is not null, retrieving it in the OwnerDetail class shows null as if I did not pass it it. I've seen several example, but I am not able to get it right. What am I doing wrong here?
Note: If I were to call the AsyncTask in the OwnerDetail class and set the ListAdapter, it will work fine. The issue with that is that it will display a list of owners as soon as the user is logged in which is not the expected behavior. The behavior that I want is to login first, search for an owner, display the owner, double click on an owner, and finally display a list of cars that the owner owns. I am doing this project, so I can learn how to use ListFraments.

Your code has a lot of problems:
1 Never call lifecycle methods on your own like you do in the OwnerDetail class with super.onActivityCreated(savedInstanceState);
2 Bundle values = getActivity().getIntent().getExtras(); ... values.getParcelableArray("test"); will normally fail because this piece of code will get the activity reference, get the Intent that started the activity and then try to find data passed in under the test key in that Intent. You don't pass such data to the People activity so there will be nothing to be found. You'd normally want to pass a Bundle containing the data at the moment of the creation of the fragment.
3 If you use the fragment in the xml layout you'll not be able to use a Bundle to pass data, instead you either add the fragment manually with transactions and then use a Bundle or you create a setter method in the fragment class and use that. So instead of Bundle data = new Bundle(); data.putParcelableArray("test", myOwners);, which does nothing, get a reference to your fragment and pass the myOwners array through a method.
4 Your AsyncTask will be pretty useless if you use them with .get() because the get() method will wait the AsyncTask to finish, blocking the UI tread as well. Instead you should just start the AsyncTask and then in the onPostExecute() pass the data around.
Here is an example with a simple method which will not change most of your code(which will happen if you manually add the fragments):
// where you start the owner asynctask
if(!searchByName.matches("")) {
OnwerAsyncTask asynTask = new OnwerAsyncTask(People.this);
asynTask.execute("");
}
//...
Then change the OnwerAsyncTask like this:
public class OnwerAsyncTask extends AsyncTask<String, Void, List<Owner>> {
private List<Owner> items = null;
private FragmentActivity mActivity;
public OnwerAsyncTask(FragmentActivity activity) {
mActivity = activity;
}
// doInBackground()...
#Override
protected void onPostExecute(List<Owner> result) {
//I'm assuming that items is the data you want to return, so
// find the OwnerDetail fragment and directly assign the data
OwnerDetail fragment = (OwnerDetail)mActivity.getSupportFragmentManager().findFragmentById(R.id.fOwnerDetail);
fragment.setData(); // to setData you'll pass the data you have in the AsyncTask
// the items list? or you transform that into an array?
}
and in the OwnerDetail fragment:
public class OwnerDetail extends ListFragment {
OwnerAdapter ownerAdapter = null;
public void setData() {
// update the adapter, create a new one etc.
}
