onClick child item in ExpandableListView - java

I need to add onClick to the child items in ExpandableListView. I have reviewed other posts regarding this, but I could not integrate the code into mine, possibly due to a different variation of ExpandableListView codes.
It would be great if you can provide some in code explanation as well. Many thanks.
Here are my source codes:

You can set child click of expandable list in two ways
1.write child click event inside the getChildView() method.
#Override
public View getChildView(final int groupPosition, final int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
Page page =(Page) getChild(groupPosition, childPosition);
convertView = inflater.inflate(R.layout.child_list_layout, null);
Button mButton=(Button)convertView.findViewById(R.id.button1);
mButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Your code goes here ....
}
});
return convertView;
}
2.write click directly from expandable listview.
mExpandableListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
#Override
public boolean onChildClick(
ExpandableListView parent, View v,
int groupPosition, int childPosition,
long id) {
GoCategory(mainMenusList.get(groupPosition)
.getPagesList().get(childPosition));
return false;
}
});

Is there a way of opening each searchable listview item in a dial pad?

im new to android development and i have managed to develop an application with a listview of name, phone number and district, which is searchable and it is working really well. im using positions to click and take me to the dial pad, but the problem is, if an item is searched, it does not mantain its position given to it initially. what i want when a user searches for a name or district, it opens in the dial pad with a number written there.
Here is my contacts.java
public class Contacts extends AppCompatActivity {
ListView listView;
String[] name = {"Achibu john peter - Serere - 0772698033", "Agaba - Amon - Rukiga -

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contacts);

getSupportActionBar().setTitle("DFO Contacts");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
listView = findViewById(R.id.listview);
arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, name);
listView.setAdapter(arrayAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
if (position == 0){
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel: +256772698033"));

}
});
}

You need to use custom Array Adapter with custom Layout with a TextView and add OnClickListener for each TextView.
I've changed your code to make it work.

Android list view with adapter displays only the first item (several times)

I created a ListView and a custom adapter to use with the list view. For some reason, if I add more than one item to the list, it does show several items, but all of them are identical to the first one.
At first I used a layout file to create each item but then I gave up and dynamically created a text view just to test it. It didn't work in both ways.
List with same item
Here is my code:
ArtistAdapter.java
package com.example.list2;
import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
import java.util.ArrayList;
public class ArtistAdapter extends BaseAdapter
{
private ArrayList<String> artists;
private Context context;
private LayoutInflater inflater;
public ArtistAdapter(Context context, ArrayList<String> artists)
{
super();
this.context = context;
this.artists = artists;
this.inflater = LayoutInflater.from(context);
}
public ArtistAdapter(Context context)
{
this(context, new ArrayList<String>());
}
#Override
public int getCount() {
return artists.size();
}
#Override
public String getItem(int i) {
return artists.get(i);
}
#Override
public long getItemId(int i) {
return i;
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
View v = view;
if(v == null)
{
//LayoutInflater li = ((Activity)context).getLayoutInflater();
//v = inflater.inflate(R.layout.item,viewGroup,false);
//((TextView)v.findViewById(R.id.name)).setText((String)getItem(i));
v = new TextView(context);
((TextView)v).setText(getItem(i));
((TextView)v).setTextSize(50);
}
return v;
}
public void add(String name)
{
artists.add(name);
notifyDataSetChanged();
}
}

Do you need to use a custom Adapter? Otherwise this code works well using ArrayAdapter:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
ListView l;
EditText et;
Button bt;
ArrayAdapter<String> artistAdapter;
List<String> listItems = new ArrayList<String>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
l = findViewById(R.id.list);
et = findViewById(R.id.input);
bt = findViewById(R.id.submit);
bt.setOnClickListener(this);
artistAdapter = new ArrayAdapter<String>(this,R.layout.item, R.id.textView,listItems);
l.setAdapter(artistAdapter);
}
#Override
public void onClick(View v) {
String inp = getInput();
if(inp.length() == 0) return;
listItems.add(inp);
artistAdapter.notifyDataSetChanged();
empty();
}
private String getInput()
{
return et.getText().toString();
}
private void empty()
{
et.setText("");
}
}
You need to update the arraylist and then set the adapter. For some reason notify adapter is not working. Here's the solution:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
ListView l;
EditText et;
Button bt;
ArtistAdapter artistAdapter;
ArrayList<String> arrayList = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
l = findViewById(R.id.list);
et = findViewById(R.id.input);
bt = findViewById(R.id.submit);
bt.setOnClickListener(this);
artistAdapter = new ArtistAdapter(this, arrayList);
l.setAdapter(artistAdapter);
}
#Override
public void onClick(View v) {
String inp = getInput();
if(inp.length() == 0) return;
arrayList.add(inp);
l.setAdapter(artistAdapter);
empty();
}
private String getInput()
{
return et.getText().toString();
}
private void empty()
{
et.setText("");
}
}
====
public class ArtistAdapter extends BaseAdapter
{
private ArrayList artists;
private Context context;
public ArtistAdapter(Context context, ArrayList<String> artists)
{
super();
this.context = context;
this.artists = artists;
}
#Override
public int getCount() {
return artists.size();
}
#Override
public String getItem(int i) {
return artists.get(i);
}
#Override
public long getItemId(int i) {
return i;
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
View v = view;
if(v == null)
{
v = new TextView(context);
((TextView)v).setText(getItem(i));
((TextView)v).setTextSize(50);
}
return v;
}
}

How to add a button to ExpandableListView in AndroidStudio?

We are developing an Android application which creates plans and schedules. I have an ExpandableListView and I need to add deleting buttons where the user can delete a specific schedule or the complete plan. The Schedule item is the Child of the Plan item.
I was developing deleting the schedule part first. I thought that each child item can include one text view and the deleting button. This is the schedule_group.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="2">
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1.8">
<TextView
android:id="#+id/scheduleGroup"
android:layout_width="355dp"
android:layout_height="wrap_content"
android:paddingLeft="?android:attr/expandableListPreferredItemPaddingLeft"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:textColor="#android:color/black" />
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.2">
<ImageButton
android:id="#+id/scheduleDeleteBtn"
android:layout_width="wrap_content"
android:layout_height="match_parent"

The problem is here:
private void deleteSchedule() {
}
private void createAPlan(int sch){
listPlanName.add("Plan#"+(count+1));
List<String> schedules = new ArrayList<String>();
if(sch > 0 ){
for (int i = 1; i <= sch; i++){
schedules.add("Schedule#" + i);
}
}
listSchedules.put(listPlanName.get(count),schedules);
count++;
}
}
I'm not sure how to access the child item via the button. If you could help that would be great! Thank you.
I added the remove part under getChildView() method. If anyone needs a similar solution:

Android RecyclerView item width in fragment

I have a RecyclerView that gets inflated in a Fragment. The problem is, when the items count gets more than views height, every item that is in the view will get a width of highest content (I mean all will get wrap content of highest width). In the image it's more specific, also after scrolling those views that will get refreshed will have a correct width (match parent). I already have tried those code suggestions on other questions but still problem exists. here is my code:
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.complex_item, parent, false);
return new ViewHolder(itemView);
}
The xml layout for items:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:id="#+id/baseBg"
android:orientation="vertical">
<LinearLayout
android:id="#+id/expand_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/list_item_background"
android:foreground="?selectableItemBackground"
android:gravity="center|right"
android:orientation="vertical"
android:padding="10dp">
<TextView
android:id="#+id/textViewTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:textColor="#color/colorPage5"
android:textSize="20sp"
android:textStyle="bold" />
</LinearLayout>
</LinearLayout>
Code snippet that does the fragment replace:
mainPageFrameLayout.removeAllViews();
FragmentTransaction ft =
getSupportFragmentManager().beginTransaction();
ft.replace(R.id.mainPageFrameLayout, new MojtamaFragment(id, "3"));
ft.commit();
And the mainPageFrameLayout:
<FrameLayout
android:id="#+id/mainPageFrameLayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:animateLayoutChanges="true"
android:background="#color/colorPage5" />
The adapter and the onCreateView:
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.recycler_view_fragment, container, false);
final RecyclerView recyclerView = rootView.findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
...
//(this part items is getting generated by a Http Request)
...
recyclerView.setAdapter(new SimpleAdapter(recyclerView, id, title, getActivity(), complexID,MojtamaFragment.this));
return rootView;
}
Images:
Edit: Image explanation: as you can see in image 1 when items numbers gets more than views height items width gets wrap_content instead of match_parent (Image 2 is the correct one that it should be) in image 3 as you can see after i did scroll, items that get's re-instantiated gets correct width. I hope you get the point.

After so much editing and experiencing i found a part of code from my xml layout (the one that FrameLayout is in it and fragment gets replaced by it) has something to do with error:
<android.support.constraint.ConstraintLayout 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="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.ahrabi.ojekavir.CityActivity"
tools:showIn="#layout/activity_city">
after removing app:layout_behavior and changing ContraintLayout to some Linear or RelativeLayout problem now is gone.
I don't know why this part raises such problem, but it has definitely a reason.

Android studio: list view with check boxes

This activity consists of typing an ingredient (then showing it) and check a checkbox next to it. I have the following bugs that I can't get rid of (I've been searching for 5 hours for a solution):
If I press back so the keyboard hides,when I click on the search view,it never shows again but for going to the home screen and entering back again.
If I check a checkbox and scroll,there will be other checkboxes randomly checked.
How can I put in an array the ingredients that I have checked and send that array to the next activity?(activity_ingredient list)
