Android ListView: Custom ListItem not displayed correctly

Android ListView: Custom ListItem not displayed correctly - android

based on an example i tried to create a ListView that displays custom ListItems. I define the ListItem in XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip" >
<ImageView
android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentBottom="true"
android:layout_alignParentTop="true"
android:layout_marginRight="6dip"
android:contentDescription="TODO"
android:src="#drawable/icon" />
<TextView
android:id="#+id/secondLine"
android:layout_width="fill_parent"
android:layout_height="26dip"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_toRightOf="#id/icon"
android:ellipsize="marquee"
android:singleLine="true"
android:text="Description"
android:textSize="12sp" />
<TextView
android:id="#+id/firstLine"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#id/secondLine"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_alignWithParentIfMissing="true"
android:layout_toRightOf="#id/icon"
android:gravity="center_vertical"
android:singleLine="true"
android:text="Example application"
android:textSize="16sp" />
</RelativeLayout>
I created a class to hold the data shown in a ListItem:
public class UserRecord {
public String username;
public String email;
public UserRecord(String username, String email) {
this.username = username;
this.email = email;
}
}
I also have a custom ArrayAdapter:
public class UserItemAdapter extends ArrayAdapter<UserRecord> {
private ArrayList<UserRecord> users;
public LayoutInflater vi;
private Context context;
public UserItemAdapter(Context context, int textViewResourceId, ArrayList<UserRecord> users) {
super(context, textViewResourceId, users);
this.users = users;
this.context = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.listitem, null);
}
UserRecord user = users.get(position);
if (user != null) {
TextView username = (TextView) v.findViewById(R.id.firstLine);
TextView email = (TextView) v.findViewById(R.id.secondLine);
Log.v(TAG, "user " + user.username);
Log.v(TAG, "mail " + user.email);
if (username != null) {
Log.v(TAG, "username NOT null");
username.setText("user " + user.username);
}
if (email != null) {
Log.v(TAG, "email NOT null");
email.setText("Email: " + user.email);
}
}
return v;
}
}
Initialisation:
ArrayList<UserRecord> appointment;
UserItemAdapter aa;
ListView lv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv = (ListView) findViewById(R.id.listView1);
b1 = (Button) findViewById(R.id.button1);
b1.setOnClickListener(this);
appointment = new ArrayList<UserRecord>();
aa = new UserItemAdapter(this, android.R.layout.simple_list_item_1, appointment);
lv.setAdapter(aa);
}
And finally, when i push a button:
public void onClick(View v) {
if (v == b1) {
UserRecord ur = new UserRecord("User " + i, "mail#mail.net");
Log.v(TAG, "button 1 " + i);
aa.add(ur);
} else {
Log.v(TAG, "unknown");
}
}
Problem is that "email" is displayed, but "username" not, though it is handled the same way, i see no difference. Also, the if() where it should be set is taken.
Has anybody got a hint on what is wrong?
Best regards
Torsten

Change this
aa = new UserItemAdapter(this, android.R.layout.simple_list_item_1, appointment);
To this;
aa = new UserItemAdapter(this, R.layout.listitem, appointment);
And try this:
public void onClick(View v) {
if (v == b1) {
UserRecord ur = new UserRecord("User " + i, "mail#mail.net");
Log.v(TAG, "button 1 " + i);
appointment.add(ur);
aa.notifyDataSetChanged();
} else {
Log.v(TAG, "unknown");
}
}

I could be mistaken, but I am almost sure you should be doing this:
public void onClick(View v) {
if (v == b1) {
UserRecord ur = new UserRecord("User " + i, "mail#mail.net");
Log.v(TAG, "button 1 " + i);
users.add(ur);
} else {
Log.v(TAG, "unknown");
}
}
Instead of:
public void onClick(View v) {
if (v == b1) {
UserRecord ur = new UserRecord("User " + i, "mail#mail.net");
Log.v(TAG, "button 1 " + i);
aa.add(ur);
} else {
Log.v(TAG, "unknown");
}
}
I have never added an item to my ADAPTER class, but always to the LIST of objects. In this case "users" rather than "aa".

The problem is in your listitem.xml file. Try to change to this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip" >
<ImageView
android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_marginRight="6dip"
android:contentDescription="TODO"
android:src="#drawable/icon" />
<TextView
android:id="#+id/firstLine"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toRightOf="#id/icon"
android:gravity="center_vertical"
android:text="Example application"
android:textSize="16sp" />
<TextView
android:id="#+id/secondLine"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/icon"
android:ellipsize="marquee"
android:text="Description"
android:layout_below="#id/firstLine"
android:textSize="12sp" />
</RelativeLayout>

Recycler view onBindViewHolder is repeating a weird pattern

I am working on a messaging app which has swipe option to mute or lock conversations, when we press the mute or lock button, small icons are displayed on Recycler view item, but when I try to mute or even lock a certain message it shows the icons on that item but the icons also appears on elements after every 10 counts.
For Example, If I lock the message at position 1, element at position 12 also shows the same icons, if I removed the icon from the first position, icons from the later position is also removed. Any help would be highly appreciated as I am new to android development and still trying to learn.

Listview update another raw on update of selected raw

I working on one Shopping Cart application.
In which i show list of products and in that every raw there is "Add to Cart" button,
Whenever user clicks on it then that button goes to disable and another view which holds add and subtract quantity should be display.
But when i clicks on any single product "Add to Cart" button then that view is going to be update, But when i scroll listview then another view gets update automatically (Not all).

Can't click on Custom ListView

I was stuck all day. Couldn't find my mistake.
I created a Custom ListView, and I just want to be able to click on it to launch a new intent in HourListView.
public class CustomList extends ArrayAdapter<String> {
private final ArrayList<String> hourList;
private final Activity context;
public CustomList(Activity context,
ArrayList<String> hourList) {
super(context, R.layout.hour_list_adapter, hourList);
this.context = context;
this.hourList = hourList;
}
#Override
public View getView(int position, View view, ViewGroup parent) {
View rowView = view;
ViewHolder viewHolder = null;
// LayoutInflater inflater = context.getLayoutInflater();
// View rowView= inflater.inflate(R.layout.hour_list_adapter, parent, false);
if(rowView == null)
{
LayoutInflater inflater = context.getLayoutInflater();
rowView = inflater.inflate(R.layout.hour_list_adapter, parent, false);
viewHolder = new ViewHolder();
viewHolder.type_frequenceTV = (TextView) rowView.findViewById(R.id.type_frequence);
viewHolder.dateTV = (TextView) rowView.findViewById(R.id.date);
viewHolder.dureeTV = (TextView) rowView.findViewById(R.id.duree);
viewHolder.commentaireTV = (TextView) rowView.findViewById(R.id.commentaire);
viewHolder.simuIV = (ImageView) rowView.findViewById(R.id.simulateur);
viewHolder.doubleIV = (ImageView) rowView.findViewById(R.id.doubleFrequence);
rowView.setTag(viewHolder);
}
else
{
viewHolder = (ViewHolder)rowView.getTag();
}
viewHolder.type_frequenceTV.setText(HourListActivity.hourObjects.get(position).get("type_frequence").toString());
viewHolder.dureeTV.setText(HourListActivity.hourObjects.get(position).get("duree").toString());
viewHolder.commentaireTV.setText(HourListActivity.hourObjects.get(position).get("comment").toString());
Date dateAndTime = (Date) HourListActivity.hourObjects.get(position).get("date");
SimpleDateFormat format1 = new SimpleDateFormat("dd/MM/yy à HH:mm");
String formatted = format1.format(dateAndTime.getTime());
viewHolder.dateTV.setText("Le " + formatted);
if ((Boolean) HourListActivity.hourObjects.get(position).get("double"))
{
viewHolder.doubleIV.setVisibility(View.VISIBLE);
}
else
{
viewHolder.doubleIV.setVisibility(View.GONE);
}
if ((Boolean) HourListActivity.hourObjects.get(position).get("simulateur"))
{
viewHolder.simuIV.setVisibility(View.VISIBLE);
}
else
{
viewHolder.simuIV.setVisibility(View.GONE);
}
rowView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
return rowView;
}
static class ViewHolder
{
TextView type_frequenceTV;
TextView dateTV ;
TextView dureeTV ;
TextView commentaireTV ;
ImageView simuIV ;
ImageView doubleIV ;
}
}
Then this is the HourListActivity where I want to be able to click.
public class HourListActivity extends AppCompatActivity {
//ArrayAdapter<String> arrayAdapter;
CustomList adapter;
ListView hourListView;
static ArrayList<String> hourList;
static ArrayList<String> hourListID;
static ArrayList<ParseObject> hourObjects = new ArrayList<ParseObject>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hour_list);
hourList = new ArrayList<>();
hourListID = new ArrayList<>();
hourListView = (ListView) findViewById(R.id.listView);
adapter = new CustomList(HourListActivity.this,hourList);
//arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, hourList);
hourListView.setAdapter(adapter);
hourListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
System.out.println("CLIC !!!!!!!!!!!!!!!!!!!!!");
ParseQuery<ParseObject> query = ParseQuery.getQuery("Frequence");
query.getInBackground(hourListID.get(position), new GetCallback<ParseObject>() {
public void done(ParseObject object, ParseException e) {
if (e == null) {
Intent intent = new Intent(getApplicationContext(), ModifyHourActivity.class);
intent.putExtra("objectID", object.getObjectId());
startActivity(intent);
} else {
// something went wrong
}
}
});
}
});
ParseQuery<ParseObject> query = ParseQuery.getQuery("Frequence");
query.whereEqualTo("username", ParseUser.getCurrentUser().getUsername());
System.out.println("username: " + ParseUser.getCurrentUser().getUsername() );
query.orderByDescending("date");
query.findInBackground(new FindCallback<ParseObject>() {
#Override
public void done(List<ParseObject> objects, ParseException e) {
if (e == null)
{
if (objects.size() > 0)
{
hourObjects.clear();
for (ParseObject frequence : objects)
{
String result = "";
result += frequence.get("date") + " - "
+ frequence.get("type_frequence") + " - "
+ frequence.get("duree") + " - "
+ frequence.get("comment") + " - "
+ frequence.get("double") + " - "
+ frequence.get("simulateur") + " - ";
System.out.println("Résultat : " + result);
hourList.add(result.toString());
hourListID.add(frequence.getObjectId());
ParseObject newHour = new ParseObject("Temp");
newHour.put("username", frequence.get("username"));
// newHour.put("id", frequence.get("objectId"));
newHour.put("type_frequence", frequence.get("type_frequence"));
newHour.put("date", frequence.get("date"));
newHour.put("duree", frequence.get("duree"));
newHour.put("comment", frequence.get("comment"));
newHour.put("double", frequence.get("double"));
newHour.put("simulateur", frequence.get("simulateur"));
hourObjects.add(newHour);
}
Toast.makeText(HourListActivity.this, "Liste des heures récupérée !",
Toast.LENGTH_LONG).show();
adapter.notifyDataSetChanged();
}
}
else
{
}
}
});
A lastly my xml file for the Custom View:

Thanks in advance for any help ! :)

What happens when you delete this part in your adapter ?
rowView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
I guess what happens is that the view are created after you have defined the ItemClickListener in your activity, resulting in the ClickListener being overriden at run time by the one in your adapter.

As far as I am concerned if you are facing an error with setOnClickListener you can try this
Go to Tools--> sync with Gradle.
It helped me when I was stucked with the intent problem!

Item missing from android grid view on scroll

Shortcuts for removing and editing in a listview in android

I have a listview that is a list of events. For each event, I want to have shortcut icons right next to its title for editing and removing. If I tab one of those, it should bring me to another Intent for editing/removing events. How do I achieve this?
My xml has a listview like this:
<ListView
android:id="#+id/listView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1" >
</ListView>
and for each text view:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/rowTextView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp" >
</TextView>
Thank you!

What you need to do is to create a custom Adapter and override the getView method like so:
private class MySecondAdapter extends ArrayAdapter<MiniTask>
{
private ArrayList<MiniTask> list;
public MySecondAdapter(Context context, int textViewResourceId, ArrayList<MiniTask> miniTaskList)
{
super(context, textViewResourceId, miniTaskList);
this.list = new ArrayList<MiniTask>();
this.list.addAll(miniTaskList);
}
public View getView(final int position, View convertView, ViewGroup parent)
{
miniTask = miniTaskList.get(position);
ViewHolder holder = new ViewHolder();
{
LayoutInflater inflator = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflator.inflate(R.layout.check_list_item_new, null);
holder.title = (TextView) convertView.findViewById(R.id.tvItemTitle);
holder.commentsPicturesButton = (ImageView) convertView.findViewById(R.id.iAddCommetOrPicture);
holder.commentsPicturesButton.setTag(position);
holder.commentsPicturesButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
Intent intent = new Intent(getApplicationContext(), PicturesAndCommentsActivity.class);
intent.putExtra(TasksListActivity.KEY_ID, task.getId());
intent.putExtra("mini_task_text", miniTask.getTitle());
startActivity(intent);
}
});
holder.selected = (CheckBox) convertView.findViewById(R.id.cbCheckListItem);
holder.selected.setTag(position);
holder.selected.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
{
Log.d(TAG, "pressed the checkbox: " + v.getId() + " in position: " + position + " tag: " +v.getTag() +" and item from array: " + miniTaskList.get(position) );
CheckBox checkbox = (CheckBox) v;
miniTaskList.get(position).setSelected(checkbox.isChecked());
numOfCheckedMiniTasks = 0;
for(int i=0;i<miniTaskList.size();i++)
{
miniTask = miniTaskList.get(i);
if(miniTask.isSelected())
{
numOfCheckedMiniTasks ++;
}
}
int percent = (int)(numOfCheckedMiniTasks * 100.0f) / miniTaskList.size();
Log.d(TAG, "the percentage is: " +percent);
tasksRepository.get(tasksRepository.indexOf(task)).setMiniTasksPercentageComplete(percent);
}
}
});
}
holder.title.setText(miniTask.getTitle());
holder.selected.setChecked(miniTask.isSelected());
return convertView;
}
}
In this case I have a checkbox for every row as well, you can ignore it, and the holder is:
static class ViewHolder
{
TextView title;
CheckBox selected;
ImageView commentsPicturesButton;
}
While the XML layout for every row is:
<?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="wrap_content"
android:background="#drawable/try2"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<CheckBox
android:id="#+id/cbCheckListItem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginBottom="10dp"
android:background="#drawable/checkbox_checklist_selector"
android:button="#drawable/checkbox_checklist_selector" />
<TextView
android:id="#+id/tvItemTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="5dp"
android:paddingRight="10dp"
android:paddingTop="13dp"
android:text="#string/checklist_item_string"
android:textColor="#color/my_darker_gray" />
</LinearLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:paddingTop="6.5dp" >
<ImageView
android:id="#+id/iAddCommetOrPicture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:contentDescription="#drawable/comment_or_photo_icon"
android:src="#drawable/comment_or_photo_icon" />
</RelativeLayout>
UPDATE:
holder.iParameterWidget.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
currentParameterPosition = position;
}
}

for this you have to create your custom row separately. There are plenty of example you can find. You can see following links to start
