Row layout not inflated in Android

Row layout not inflated in Android - android

I have a problem. I started a few weeks ago learning Android. I am trying to create an adapter for a list. But the lists doesn't show up AT ALL. Any ideas why? The items are objects type Verb. Here is my code:
///my main activity///
public class Verbs extends Activity {
private ListView listViewVerbs;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_verbs);
//instantiate Verb
Verb[] VerbData=new Verb[3];
VerbData[0] = new Verb("machen","mache","machen","mache","machen","mache","machen");
VerbData[1] = new Verb("machen","mache","machen","mache","machen","mache","machen");
VerbData[2] = new Verb("machen","mache","machen","mache","machen","mache","machen");
//pass data to adapter
VerbAdapter adapter = new VerbAdapter(this,R.layout.row_verbs,VerbData);
listViewVerbs = (ListView)findViewById(R.id.list);
listViewVerbs.setAdapter(adapter);
listViewVerbs.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String wasClicked = view.findViewById(R.id.nameVerb).toString();
Toast.makeText(Verbs.this,
"You clicked: " + wasClicked, Toast.LENGTH_LONG)
.show();
}
});
}
}
//class for an item of the list
public class Verb {
public String verbname;
public String fpersg;
public String fperspl;
public String sperssg;
public String sperspl;
public String tperssg;
public String tperspl;
//constructor
public Verb(String s, String s1, String s2, String s3, String s4, String s5,String s6){
this.verbname = s;
this.fpersg = s1;
this.fperspl = s2;
this.sperssg = s3;
this.sperspl = s4;
this.tperssg = s5;
this.tperspl = s6;
}
//setters
public void setVbName(String vbName){
this.verbname = vbName;
}
public void setFpersg(String fpersg){
this.fpersg = fpersg;
}
public void setFperpl(String fperpl){
this.fperspl = fperpl;
}
public void setSpersg(String spersg){
this.sperssg = spersg;
}
public void setSperspl(String sperpl){
this.sperspl = sperpl;
}
public void setTpersg(String tpersg){
this.tperssg = tpersg;
}
public void setTperpl(String tperpl){
this.tperspl = tperpl;
}
//getters
public String getVerbname(){
return this.verbname;
}
public String getFpersg(){
return this.fpersg;
}
public String getFperpl(){
return this.fperspl;
}
public String getSpersg(){
return this.sperssg;
}
public String getSperpl(){
return this.sperspl;
}
public String getTpersg(){
return this.tperssg;
}
public String getTperspl(){
return this.tperspl;
}
}
//the adapter
public class VerbAdapter extends ArrayAdapter<Verb>{
Context mContext;
int layoutResourceId;
Verb data[] = null;
public VerbAdapter(Context mContext, int layoutResourceId, Verb[] data){
super(mContext, layoutResourceId, data);
this.mContext = mContext;
this.layoutResourceId =layoutResourceId;
this.data = data;
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
if (convertView == null){
LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
convertView = inflater.inflate(layoutResourceId,parent, false);
}
TextView textView0 = (TextView) convertView.findViewById(R.id.nameVerb);
TextView textView1 = (TextView) convertView.findViewById(R.id.firstpersonsg);
TextView textView2 = (TextView) convertView.findViewById(R.id.firstpersonpl);
TextView textView3 = (TextView) convertView.findViewById(R.id.secondpersonsg);

textView3.setText(verb.sperssg);
textView4.setText(verb.sperspl);
textView5.setText(verb.tperssg);
textView6.setText(verb.tperspl);
return convertView;
}
}
------and two XML files named activity_verbs where the list is declared and row_verbs where the layout of each item is declared-----

I copied your code with only one change:
I removed
tools:context="${relativePackage}.${activityClass}"
from activity_verbs and it works like a charm for me:
I uploaded my test-project with your code to DropBox, feel free to download it:

P.S. Very well structured question, good job!

this My Adapter :
public class DialogWeatherAdapter extends
RecyclerView.Adapter<DialogWeatherAdapter.DialogViewHolder> {

Context context;
Activity c;
public DialogWeatherAdapter(ArrayList<Example2> data, Context context,

public class DialogViewHolder extends RecyclerView.ViewHolder {

ImageView ivIconItem;
public DialogViewHolder(View itemView) {
super(itemView);
tvCurrentDateItem = itemView.findViewById(R.id.current_date_weather_item);
tvDescriptionItem = itemView.findViewById(R.id.description_item);
tvTemperatureItem = itemView.findViewById(R.id.temperature_item);
ivIconItem = itemView.findViewById(R.id.icon_weather_item);
}
}
}
enter image description here

The reason for this is -
The Item file (R.layout.item_weathers) has height match parent. Change it to wrap_content as shown -
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
and it will show all the items.

String uuid = gEvent.getUuid();
Boolean hasPhoto = gEvent.isHasPhoto();
profileName.setText(gEvent.getProfileUsername());
if(hasPhoto) {
final long ONE_MEGABYTE = 1024 * 1024 * 5;
pathRef.getBytes(ONE_MEGABYTE).addOnSuccessListener(new OnSuccessListener<byte[]>() {
#Override
public void onSuccess(byte[] bytes) {
Bitmap picturel = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
ImageView imageView = (ImageView) customView.findViewById(R.id.geventEventPhoto);
Drawable d = new BitmapDrawable(mContext.getResources(),picturel);
imageView.setBackground(d);
Log.i("CA","Entered hasRetrieved Photo and update hasLoaded");

return customView;
}
public void readMoreFunction(){

if(wantsToReadMore){ //wants to read less now
Log.i("CA","Entered Read Less Function");
eventPhoto.setAlpha(1f);
descriptionGevent.setText("");
eventDetails.setText("");
readMoreButton.setText("Read More");
titleGevent.setText(titleForGEvent);
wantsToReadMore=false;
}
else{ //Wants to read more
Log.i("CA","Entered Read More Function");
eventPhoto.setAlpha(0.5f);
descriptionGevent.setText(description);
eventDetails.setText(detailsGEvent);
titleGevent.setText("");
readMoreButton.setText("Read Less");
wantsToReadMore=true;
}
So my problem is that whenever I am calling this CustomAdapter, when only one list Item is there it works perfectly, however whenever there are multiple list items, the adapter starts behaving strangely. For instance, whenever there are 2 items, If i press the " Read More " button for the first item, it triggers for the second item, even though in the logs it shows that data on which it is working is the first item itself.
If there are more than 2 items , then the above pattern is observed , i.e, whenever I click the "Read More" button of a given item, it triggers for the next item in the listview. Sometimes it is just stuck on "Loading " even after the image has loaded or the "Read More" button doesn't even respond.
I have been banging my head for the past two days , looking for the bug. Hope you guys can help me.Thanks in Advance.
PS:- The "Load More" Button is out of place, excuse me for that.

Inside GEvent class create a boolean field,
class GEvent {
private boolean readMoreClicked;
public boolean isReadMoreClicked(){
return readMoreClicked;
}
public void setReadMoreClicked(boolean readMoreClicked){
this.readMoreClicked = readMoreClicked;
}
}
Inside getView,
#Override
public View getView(int position, View convertView, ViewGroup parent) {
....
if(gEvent.isReadMoreClicked()) {
Log.i("CA","Entered More Less Function");
...
} else {
Log.i("CA","Entered Less More Function");
...
}
readMoreButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(hasLoaded) {
Log.i("CA","Entered hasLoaded Function");
// user has clicked Read More. Save the state
gEvent.setReadMoreClicked(!gEvent.isReadMoreClicked());
notifyDataSetChanged();
} else {
Toast.makeText(mContext,"Loading....",Toast.LENGTH_LONG).show();
}
}
});
...
}
It may need some editing. But I hope you get the idea. :)

Tapping rows in Listview not working even w/ SetOnItemClicklistener in Android

For some reason tapping a row in my list view doesn't seem to work even if I have the correct listener code. There are only textviews in the template of the lists. I know there's been discussion about assigning a listener when there is a button in the template of a list view. see here.
Here is my code:
ScheduleActivity:
public class ScheduleActivity extends AppCompatActivity {
private String url;
JSONObject data = null;
Toolbar toolbar;
Intent intent;
String userId;
int eventId;
ListView scheduleListView;
ScheduleAdapter scheduleAdapter;
ArrayList<Schedule> scheduleList = new ArrayList<>();
DBManager dbManager = new DBManager(ScheduleActivity.this);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.schedule_layout);
Log.d("Test", ">>>ScheduleActivity<<<");
Bundle extras = getIntent().getExtras();
userId = extras.getString("userId");
eventId = extras.getInt("eventId");
toolbar = (Toolbar) findViewById(R.id.schedule_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("Schedules");
scheduleList = dbManager.getSchedules(eventId);
scheduleAdapter = new ScheduleAdapter(ScheduleActivity.this, scheduleList);
scheduleListView = (ListView) findViewById(R.id.scheduleListView);
scheduleListView.setAdapter(scheduleAdapter);
scheduleListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.w("Test", scheduleList.get(position).toString());
intent = new Intent(ScheduleActivity.this, UpdateScheduleActivity.class);
intent.putExtra("userId", userId);
intent.putExtra("eventId", eventId);
startActivity(intent);
}
});
scheduleListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
Log.w("Test", "Long click works");
return true;
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.schedule_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.new_schedule) {
intent = new Intent(ScheduleActivity.this, CreateScheduleActivity.class);
intent.putExtra("eventId", eventId);
startActivity(intent);
}else if(id == R.id.rankings){
Log.d("Test", "Rankings Activity clicked!");
}
return super.onOptionsItemSelected(item);
}
ScheduleAdapter:
public class ScheduleAdapter extends ArrayAdapter<Schedule>{
public ScheduleAdapter(Context context, List<Schedule> schedule) {
super(context, R.layout.schedule_list_row, schedule);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater eventInflater = LayoutInflater.from(getContext());
if (convertView == null) {
convertView = eventInflater.inflate(R.layout.schedule_list_row, parent, false);
}

TextView day = (TextView) convertView.findViewById(R.id.dayTextView);
club1Code.setText(singleSchedule.getClub1Id());

In Row Template xml:
android:clickable="true"
causing issue because RelativeLayout is clickable with match_parent height-width.
if you want to get click event for whole row then no need to make parent layout clickable just set setOnItemClickListener to ListView otherwise you need to set onClickListener for RelativeLayout in ScheduleAdapter class.

ListView in nested fragment showing empty list item, (only textviews not images)

After googling alot i never found any helpful answer, so i'm posting my issue here. My problem is as follows :
I've a nested fragment (MainActivity calls SettingsFragment and that fragment calls another fragment named as ContactFragment) that uses a listview in it. I'm setting data in adapter but and call adapter.notifyDataSetChanged(); it adds an item with in ListView but show only images not TextViews. I debugged my code line by line each variable has its values but list items are not displaying it. Below is my Code.
ContactsFragment extends Fragment {
public static List<ContactItem> contactList;
private ContactsItemAdapter adapter;
private ListView lvContacts;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_contacts, container, false);
return rootView;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
lvContacts = (ListView) getView().findViewById(R.id.lvContacts);
contactList = new ArrayList<ContactItem>();
contactList.add(new ContactItem(R.drawable.ic_action_overflow, "OverFlow", "Testing", SOS.CONTACT_TYPE_SMS));
adapter = new ContactsItemAdapter(getActivity(), R.layout.contact_item, contactList);
lvContacts.setAdapter(adapter);
}
Following is a Click Event for adding an item to the list
private void btnAddOnClick(int type){
contactList.add(new ContactItem(R.drawable.ic_action_call, "ABC", "123", "SMS"));
adapter.notifyDataSetChanged();
}
}
Following is fragment_contacts.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical" >
<ListView
android:id="#+id/lvContacts"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp" >
</ListView>
</LinearLayout>
By Calling btnAddOnClick adds item in listview but empty like this
here you can see it shows call icon but not showing text views values. Please tell me what i'm doing wrong.
Here is adapter
public class ContactsItemAdapter extends ArrayAdapter<ContactItem> {
private LayoutInflater mInflater;
public ContactsItemAdapter(Context context, int resource,
List<ContactItem> contactList) {
super(context, resource, contactList);
mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
TextView tvName;
TextView tvValue;
ImageView ivIcon;
ContactItem rowData = ContactsFragment.contactList.get(position);
if (null == convertView) {
convertView = mInflater.inflate(R.layout.contact_item, null);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
}
holder = (ViewHolder) convertView.getTag();
tvName = holder.getName();
tvName.setText(rowData.getName());
tvValue = holder.getValue();
tvValue.setText(rowData.getValue());
ivIcon = holder.getIcon();
ivIcon.setImageResource(rowData.getIcon());
return convertView;
}
public class ViewHolder {
private View mRow;
private TextView tvName = null;
private TextView tvValue = null;
private ImageView ivIcon = null;
public ViewHolder(View row) {
mRow = row;
}
public TextView getName() {
if (null == tvName) {
tvName = (TextView) mRow.findViewById(R.id.tvName);
}
return tvName;
}
public TextView getValue() {
if (null == tvValue) {
tvValue = (TextView) mRow.findViewById(R.id.tvValue);
}
return tvValue;
}
public ImageView getIcon() {
if (null == ivIcon) {
ivIcon = (ImageView) mRow.findViewById(R.id.icon);
}
return ivIcon;
}
}
}
ContactItem Class
public class ContactItem {
private int icon;
private String name;
private String value;
private String contactType;
public ContactItem() {
icon = R.drawable.ic_action_call;
name = "";
value = "";
contactType = "";
}
public ContactItem(int icon, String nameString, String valueString,
String type) {
this.icon = icon;
this.name = nameString;
this.value = valueString;
this.contactType = type;
}
public int getIcon() {
return icon;
}
public void setIcon(int icon) {
this.icon = icon;
}
public String getName() {

}
public void setName(String name) {
this.name = name;
}
public String getValue() {

}
public void setValue(String value) {

Your code should work, I think the problem is your contact_item.xml layout. Somehow your design is hiding the text. Use a simpler layout design to see if it shows the text, try getting rid of the LinearLayout:

What i want is instead of the color darker gray set a new custom color....
Have i done it the right way or is there any other way to do it?????

View listColor;//declare this at the top
Do it onclick of listviewitem
#Override
protected void onListItemClick(ListView list, View view, int position, long id) {
if(listColor!=null){
listColor.setBackgroundColor(Color.BLACK);
listColor=view;
}else{
listColor=view;
}
listColor.setBackgroundColor(Color.BLUE); //intead of blue you can change it to something you want like darkergray
//show toast on the clicked item
String selectedValue = (String) getListAdapter().getItem(position);
Toast.makeText(this, selectedValue, Toast.LENGTH_SHORT).show();
}

For this scenario you should use setBackground() at runtime instead of relying on selector.
