Android ImageButton and Spinner not working

When user clicks on icon adjacent to the item in spinner, some action has to be performed. i have not added functionality for button click handler. Before that i am facing below issue. For button with icon, i have used ImageButton in Spinner.
But when item in spinner is selected, all the items are shown and list down is not closing.
I am using Android api 28 to test.
MainActivity.java
package com.example.ravispinner;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Spinner;
import android.widget.Toast;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
private ArrayList<FileItem> mList;
private FileAdapter mAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initList();
Spinner spinnerCountries = findViewById(R.id.spinner_countries);
mAdapter = new FileAdapter(this, mList);
spinnerCountries.setAdapter(mAdapter);
spinnerCountries.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
FileItem clickedItem = (FileItem) parent.getItemAtPosition(position);
String clickedCountryName = clickedItem.getName();
Toast.makeText(MainActivity.this, clickedCountryName + " selected", Toast.LENGTH_SHORT).show();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
private void initList() {
mList = new ArrayList<>();
mList.add(new FileItem("Edit", R.drawable.ic_action_edit));
mList.add(new FileItem("New", R.drawable.ic_action_new));
mList.add(new FileItem("Remove", R.drawable.ic_action_remove));
}
}

Whenever I send or fetch a new message, the layout of the message doesn't shift with the message rather than message get shift in other direction.
i.e left to right but it should move on the same direction.
Please tell me what I'm missing.

layout with listview and text below

I have a text below a listview and I need that if listview contains more items, to push the text down more. Because many items in my listview, causes the view to look bad. Look at the example to understand
Picture
My code is
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Mañana"
android:id="#+id/manianaTitle" />
<ListView
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="#+id/listaManiana"
android:layout_gravity="center_horizontal" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Tarde"
android:id="#+id/tardeTitle" />
<ListView
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="#+id/listaTarde"
android:layout_gravity="center_horizontal" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Noche"
android:id="#+id/nocheTitle" />
<ListView
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="#+id/listaNoche"
android:layout_gravity="center_horizontal" />
</LinearLayout>

It is better to use a ListView with section. In that case you can categorize each section in your ListView instead of using many ListViews and TextViews.
I found this example from this website and I did some modification in the code
Create your List Item View
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/photo"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_margin="32dp"
android:src="#drawable/female"
android:contentDescription="#string/app_name"/>
<TextView
android:id="#+id/photo_details"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name"
android:layout_marginLeft="16dp"
android:layout_toRightOf="#+id/photo"
android:layout_alignTop="#+id/photo"/>
</RelativeLayout>
Create a layout for the header section
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical" >
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFF"
android:gravity="center_vertical"
android:padding="5dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#FF000000" />
</LinearLayout>
Create an adapter for your List View
import java.util.ArrayList;
import java.util.TreeSet;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
class CustomAdapter extends BaseAdapter {
private static final int TYPE_ITEM = 0;
private static final int TYPE_SEPARATOR = 1;
private ArrayList<EntityObject> mData = new ArrayList<String>();
private TreeSet<Integer> sectionHeader = new TreeSet<Integer>();
private LayoutInflater mInflater;
public CustomAdapter(Context context) {
mInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void addItem(final EntityObject item) {
mData.add(item);
notifyDataSetChanged();
}
public void addSectionHeaderItem(final String item) {
mData.add(item);
sectionHeader.add(mData.size() - 1);
notifyDataSetChanged();
}
#Override
public int getItemViewType(int position) {
return sectionHeader.contains(position) ? TYPE_SEPARATOR : TYPE_ITEM;
}
#Override
public int getViewTypeCount() {
return 2;
}
#Override
public int getCount() {
return mData.size();
}
#Override
public String getItem(int position) {
return mData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
int rowType = getItemViewType(position);
if (convertView == null) {
holder = new ViewHolder();
switch (rowType) {
case TYPE_ITEM:
convertView = mInflater.inflate(R.layout.snippet_item1, null);
holder.textView = (TextView) convertView.findViewById(R.id.photo_details);
holder.photo = (ImageView)convertView.findViewById(R.id.photo)
break;
case TYPE_SEPARATOR:
convertView = mInflater.inflate(R.layout.snippet_item2, null);
holder.textView = (TextView) convertView.findViewById(R.id.textSeparator);
break;
}
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.textView.setText(mData.get(position).getText());
holder.setImageResource(mData.get(position).getImage());
return convertView;
}
public static class ViewHolder {
public TextView textView;
public ImageView photo;
}
}

I've already tried changing the layouts as suggested here but the ListView is still not revealed.
Any ideas why it is not showing? Sorry for the code dump but I really cannot figure out what the heck is going on.
P.S. I did set the adapter to the ListView in the main activity.
adapter = new RepairReportListViewAdapter(this, errorNames, statuses, materialsInUse);
lvErrors.setAdapter(adapter);

your ListView does not inflate nothing because getCount is returning 0
change
#Override
public int getCount()
{
return 0;
}
with
#Override
public int getCount()
{
return (stat == null) ? 0 : stat.size();
}
Also, instead of keeping three differents ArrayList, you can create a class that holds all the info you need and an ArrayList of this class

How to Make Instagram Listview in android?

I want to make listview same like instagram...(Sectionised)
I searched in google and find some examples, but it is not working properly as I need.
This is the link i searched : Link 1 and Link 2. But in the first link I coudn't find any solution for instagram-like listview.
As for fhe second link, I made a demo and I run it and it works perfectly. The only problem is that when I put two textviews in the header then it is not working .
If you can help me regarding this then it would be great for me..
This demo from Second Link..
package com.example.Section_Listview;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AbsListView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
public class InstaHeaderActivity extends Activity implements AbsListView.OnScrollListener{
ListView list;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
list = (ListView) findViewById(R.id.list);
list.setAdapter(new Adapter(this));
list.setOnScrollListener(this);
}
public void onScroll(AbsListView view, int firstVisibleItem,int visibleItemCount, int totalItemCount)
{
//the listview has only few children (of course according to the height of each child) who are visible
for(int i=0; i < list.getChildCount(); i++)
{
View child = list.getChildAt(i);
ViewHolder holder = (ViewHolder) child.getTag();
//if the view is the first item at the top we will do some processing
if(i == 0)
{
boolean isAtBottom = child.getHeight() <= holder.header.getBottom();
int offset = holder.previousTop - child.getTop();
if(!(isAtBottom && offset > 0))
{
holder.previousTop = child.getTop();
holder.header.offsetTopAndBottom(offset);
holder.header.invalidate();
}
} //if the view is not the first item it "may" need some correction because of view re-use
else if (holder.header.getTop() != 0)
{
int offset = -1 * holder.header.getTop();
holder.header.offsetTopAndBottom(offset);
holder.previousTop = 0;
holder.header.invalidate();
}
}
}
public void onScrollStateChanged(AbsListView view, int scrollState) {}
private static class Adapter extends ArrayAdapter<String> {
public Adapter(Context context) {
super(context, R.layout.row, R.id.header);
for(int i=0; i < 50; i++){
add(Integer.toString(i));
}
}
#Override

{

{

holder.header = (TextView) convertView.findViewById(R.id.header);
convertView.setTag(holder);
}

holder.header.setText(getItem(position));
return convertView;
}
}

First of all, you can't have two public classes in one file, so move
public class ViewHolder {
TextView header;
int previousTop = 0;
}
to a seperate file. And while you're at it, remove the static modifier, it's not allowed.
To display a second TextView in your header row, you have to declare it in row.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FFFFFF"
android:orientation="vertical" >
<ListView
android:id="#+id/childList"
android:layout_width="fill_parent"
android:layout_height="150dp"
android:layout_alignParentLeft="true"
android:layout_below="#+id/header"
android:layout_marginTop="16dp" >
</ListView>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<TextView
android:id="#+id/header"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:background="#000000"
android:padding="12dp"
android:textColor="#ffffff" />
<TextView
android:id="#+id/header2"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:background="#000000"
android:padding="12dp"
android:text="second textview"
android:textColor="#ffffff" />
</LinearLayout>
</RelativeLayout>
This modified row.xml will give you a layout like this:
To set the content of the second textview, change your ViewHolder class to:
public class ViewHolder {
TextView header;
TextView header2;
int previousTop = 0;
}
and change your getView-method in your activity to:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.row, parent, false);
ViewHolder holder = new ViewHolder();
holder.header = (TextView) convertView.findViewById(R.id.header);
holder.header2 = (TextView) convertView.findViewById(R.id.header2);
convertView.setTag(holder);
}
ViewHolder holder = (ViewHolder) convertView.getTag();
holder.header.setText(getItem(position));
holder.header2.setText("whatever you want");
return convertView;
}
