You need to use setAdapter only once. For changing the list item next time (for loading next 5 items), you just need to use next notifyDataSetChanged
private void loadList(int number) {
ArrayList<String> sort = new ArrayList<String>();
int start = number * NUM_ITEMS_PAGE;
for (int i = start; i < (start) + NUM_ITEMS_PAGE; i++) {
if (i < itemAList.size()) {
sort.add(itemAList.get(i));
} else {
break;
}
}
if(itemAdapter ==null){
itemAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, sort);
itemList.setAdapter(itemAdapter);
}
else{
itemAdapter.notifyDataSetChanged();
}
}

Though I didn't get what you are doing, but try to do this change:
Remove this line
itemAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, sort);
or Add add one more line below this line
itemList.setAdapter(itemAdapter);
Because you have already called :itemAdapter.notifyDataSetChanged(); it should update the list.

adding space to make each list item bigger

My app that I am creating has two listviews. My second listview does not look the same as my second one. The lines that seperate each item are too close to the text, but I want them to have space on both the top and bottom, like the first list. I have tried to change the padding and the margins but that does not works and I have also tried to change it in one of the Java classes but I get error messages.
Here are two pictures for comparison(The first list is on the left and the second list is on the right)
The second list:
<ListView
android:id="#+id/countryselector"
android:layout_width="match_parent"
android:layout_height="250dp"
android:layout_above="#+id/checkItem"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_marginTop="60dp"
android:clickable="false"/>
<TextView
android:id="#+id/checkboxtext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="#+id/emptyElement"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="NO ITEM AVAILABLE!"
android:textColor="#525252"
android:textSize="19.0sp"
android:visibility="gone" />
<Button
android:id="#+id/checklist"
android:layout_width="25dp"
android:layout_height="25dp"
android:layout_alignParentTop="true"
android:gravity="end"
android:layout_alignParentLeft="true"
android:text=""
android:background="#mipmap/arrow2"
My first list:
<TextView
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="left"
android:text="Favorites"
android:textColor="#222"
android:textSize="15dp"
android:layout_marginLeft="20dp"
android:layout_marginTop="2dp"
android:textStyle="normal" />
<Button
android:id="#+id/tofavorites"
android:layout_width="25dp"
android:layout_height="25dp"
android:layout_alignParentTop="true"
android:gravity="end"
android:layout_alignParentLeft="true"
android:text=""
android:background="#mipmap/arrow2" />
<ListView
android:layout_marginTop="60dp"
android:id="#+id/countrieselector"
android:layout_width="match_parent"
android:layout_height="250dp"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true"
android:clickable="false" />
<TextView
android:id="#+id/checkboxtext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
Here Is my adapter class for the second list:
public class AdapterFavorite extends BaseAdapter {
ArrayList<String> items;
ArrayList<String> items1;
LayoutInflater inflater;
ArrayList selectedItems;
List<Item> dummyItems;
ArrayList<Integer> itemsValue = new ArrayList<>();
Activity activity;
DbUtility dbUtility;
Context context;
AdapterFavorite(Activity activity, ArrayList<String> items, Context context) {
this.items = items;
inflater = activity.getLayoutInflater();
selectedItems = new ArrayList<String>();
this.activity = activity;
this.context = context;
dbUtility = new DbUtility(activity);
}
#Override
public int getCount() {
return items.size();
}
#Override
public String getItem(int i) {
return items.get(i);
}
#Override
public long getItemId(int i) {
return i;
}
#Override
public View getView(final int i, View view, ViewGroup viewGroup) {
dbUtility.open();
View v = view;
if (v == null) {
v = inflater.inflate(R.layout.checkboxlayoutfavorite, null);
}
TextView textview_countries = (TextView) v.findViewById(R.id.Textview_languages);
Button button = (Button) v.findViewById(R.id.checkbox);
items1 = new ArrayList<>();
textview_countries.setText(items.get(i));
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
////Where I tried to add/move items when the checkbox is clicked
dbUtility.delete_byID(items.get(i));
items.remove(i);
notifyDataSetChanged();
}
});
return v;
}
}
Here is my main Java class for the second listL:
ublic class FavoriteActivity extends AppCompatActivity {
DbUtility dbUtility;
List<Item> dummyItems = new ArrayList<>();
Button mainList;
KeyboardPrefManager keyboardPrefManager;
ArrayList<String> items;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
ListView chl = (ListView) findViewById(R.id.languageselector);
mainList = (Button) findViewById(R.id.checklist);
chl.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
items = new ArrayList<>();
dbUtility = new DbUtility(this);
dbUtility.open();
dummyItems = dbUtility.getAllContacts();
keyboardPrefManager = new KeyboardPrefManager(this);
for (int a = 0; a < dummyItems.size(); a++) {
items.add(dummyItems.get(a).getValue());
}
mainList.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(FavoriteActivity.this, MainActivity.class);
startActivity(intent);
finish();
}
});
AdapterFavorite adapter = new AdapterFavorite(this, items, this);
chl.setAdapter(adapter);
chl.setEmptyView(findViewById(R.id.emptyElement));
chl.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
String item = items.get(i); // Getting the dummy item from the List with position i
Toast.makeText(FavoriteActivity.this, "Clicked on " + item, Toast.LENGTH_SHORT).show();
keyboardPrefManager.selectKeyboard(item);
}
});}}

Please check your list item xml for both list same or not.Thanks

ListView not Appearing

I am trying to make an activity that provides a list of emergency phone numbers with the ability for the user to add their own custom entries and save them. For some reason, the ListView doesn't appear on the activity. I'm pretty sure I'm doing something wrong in the CustomAdapter class that I made to hold two text boxes in each segment of the ListView.
I'm also trying to set the listView to start a phone activity with the phone number of whatever segment was touched, and I'm unsure if I'm doing this correctly.
PhoneList.java :
public class PhoneList extends AppCompatActivity {
ArrayList<String> customList;
ArrayList<String> numList;
Bundle b;
TinyDB tinydb;
CustomAdapter dataAdapter;
ListView phoneListView;
#Override
protected void onCreate(Bundle savedInstanceState) {

customList = null;
numList = null;
tinydb = new TinyDB(this);
Button saveContact = (Button)(findViewById(R.id.button4));
b = new Bundle();
customList = tinydb.getListString("label");
ArrayList<Integer> temp = tinydb.getListInt("num");
for(int i = 0; i < temp.size(); i++){
numList.add(temp.get(i).toString());
}

#Override
public void onClick(View v) {
EditText enteredLabel = (EditText)findViewById(R.id.editText2);

Any help is much appreciated, thank you.

Change the super keyword line to
super(context,R.layout.phone_item, n);

Have you tried to override the getCount method of the CustomAdapter class ?
#Override
public int getCount() {
return labels.size();
}

You are setting your custom adapter outside onCreate() try to set it inside the onCreate().

I don't know what I am doing wrong. I need to get access to those EditText in order to user them and add the user to the SQLite DB but, as the EditText are in the Fragment, I cannot access them directly from the RegisterUser class.
Any ideas on how to solve this? I shall be really and deeply thankful.
Thanks in advance.

Try doing like this,
TextInputLayout FlayoutBirthday= (TextInputLayout) v.findViewById(R.id.flayout_birthday);
EditText i_lname = FlayoutBirthday.getEditText();

Set text inside fragment not working after revisiting fragment

I am developing an bus time table android app. I have three fragments.
Inside first fragment I have two radio buttons i.e. From Malegaon & To Malegaon. (Malegaon is name of place).
If I select From Malegaon radio button then I am setting text to sourceEditText as Malegaon. and If I select To Malegaon radio button then I am setting text to destinationEditText as Malegaon.
This condition is working fine, when I visit fragment first time, but if I revisit fragment then From Malegaon radio Button is already selected, sourceEditText is blank and destinationEditText has text as Malegaon.
Here is my snapshot and code for first fragment.
after selecting to Malegaon radio button.
I am just changing visibility of layout. (source edittext,destination edittext,search button is one layout)

this is Adapter to call fragment.

fragment = NewStandFragment.newInstance(position);
} else if (position == 2) {
fragment = MapFragment.newInstance(position);
}
return fragment;
}
}
after revisiting OldStandFragment it look like this.
I checked with adding logs everywhere possible. And I found that after revisiting OldStandFragment, toOldMalegoanRadioButton.setOnClickListner() method is getting called.
Now I want to refresh fragment when I re-visit or any other way to solve this issue.

You have to use SharedPreferences to save state of checkbox, try this code
public class StackOne extends AppCompatActivity {
SharedPreferences prefs;
private RadioButton rButton1, rButton2;
private RadioGroup rg_ContainerOld;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.stack_one);
prefs = PreferenceManager.getDefaultSharedPreferences(StackOne.this);
rButton1 = (RadioButton) findViewById(R.id.fromOldMalegoanRadioButton);
rButton2 = (RadioButton) findViewById(R.id.toOldMalegoanRadioButton);
rg_ContainerOld = (RadioGroup) findViewById(R.id.rg_ContainerOld);
GetSelectedRadioButton();
int k = prefs.getInt("rb1", 0);
if (k == 1) {
rButton1.setChecked(true);
sourceEditTextFromMalegoanOld.setText("");
} else if (k == 2) {
rButton2.setChecked(true);
sourceEditTextToMalegoanOld.setText("");
}
}
private void GetSelectedRadioButton() {
rg_ContainerOld.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
switch (group.getCheckedRadioButtonId()) {
case R.id.fromOldMalegoanRadioButton:
prefs.edit().putInt("rb1", 1).commit();
break;
case R.id.toOldMalegoanRadioButton:
prefs.edit().putInt("rb1", 2).commit();
break;
}
}
});
}
}

In your code you are dynamically setting checked state of radiobutton
fromOldMalegoanRadioButton.setChecked(true);
toOldMalegoanRadioButton.setChecked(false);
thats why your radiobutton's oncheckedchanged method will get call. And thats why code in it.
