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));
}
}

When I apply OnItemClickListener it does not do any action like intent inside the func not called. I tried toast too but nothing shown on clicking the listView Items.
I also tried OnItemSlectedListener , it also not worked for me.
What is the problem here with this code. ?

Thanks Every One. Issue was with autolink on email and phone, I make their focusable=false but nothing happened.Then I remove it and guess what? Clicklistener also starts working.

The attribute android:clickable="true" in your ListView could be overriding all of click events of its child views, you should probably remove it:
<ListView
android:clickable="true" <!-- Remove this attribute -->
android:id="#+id/listView_emp_directory_xml"
android:layout_below="#id/relatice_layout_header_emp_directory_activity_xml"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

RecyclerView is display only half screen eventhough if i set layout width matchparent

But here the problem is recycler view is displaying in half screen as the image below, I want its width to matchparent
enter image description here

I removed ConstraintLayout and instead I used RelativeLayout as a parent and it is working, Thank you guys for responding.
<RelativeLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<ImageView
android:id="#+id/imageView2"
android:layout_width="match_parent"
android:layout_height="220dp"
android:scaleType="fitXY"
app:srcCompat="#drawable/img" />
</LinearLayout>
</RelativeLayout>

Go to your imageview which you are using and make sure attributes layout height and width both are set to match_parent. Hope this will help.

You should not use match_parent for widgets within a ConstraintLayout. From the documentation:
Important: MATCH_PARENT is not recommended for widgets contained in a ConstraintLayout. Similar behavior can be defined by using MATCH_CONSTRAINT with the corresponding left/right or top/bottom constraints being set to "parent".
If you want a widget to span 100% across its parent, the way to do that in ConstraintLayout is to set the width of the widget to 0dp and specify a start and end constraint as follows for the RelativeLayout which is a child of the ConstraintLayout:
<RelativeLayout
android:layout_width="0dp"
android:layout_height="0dp"
android:background="#e2e2e2"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
In short, all children of ConstraintLayout should be constrained vertically and horizontally and match_parent should not be used.

Elements in Relative Layout showing differently when the app runs

I have a ListView created inside a fragment, and it has a search filter, the problem is XML layout showing fine in android studio but when running in the emulator or phone it's showing differently (not properly as I aligned) and also when I click the SearchView it goes under the tab navigation. Can anyone tell how to fix this?
This is the fragment:

return inflater.inflate(R.layout.individuals, container, false);
}
#Override
public void onViewCreated(View view, Bundle b) {
super.onViewCreated(view, b);
sv = (SearchView) view.findViewById(R.id.ser1);
adaptor = new IndividualsAdaptor(getActivity(), mOrganization);
setListAdapter(adaptor);
ParseQuery.getQuery("_User").findInBackground(this);
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String text) {
return false;
}
#Override
public boolean onQueryTextChange(String text) {
adaptor.getFilter().filter(text);
return true;
}
});
}
#Override
public void done(List<ParseObject> scoreList, ParseException e) {
if (e == null) {
Log.d("score", "Retrieved " + scoreList.size() + " _User");
mOrganization.clear();
mOrganization.addAll(scoreList);

} else {

I get error when trying your ListView (I think that it is individuals.xml), e.g. TextView android:id="#id/android:empty" has an attribute android:layout_below="#+id/button3" but I can't find button3 in your layout.
This may be the layout that you want, individuals.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="wrap_content"
app:srcCompat="#drawable/individuals_img"
android:src="#drawable/individuals_img"

Image not displayed in listview

Went through many demos and was not able to figure out how to get the imageview work in list view.
Tried the code however the image is not visible in listview. Other details are working fine in the list view
Please help.
Following is the code
The mainactivity has tabhost. Under the second tab listview is present.
listdata is the data that i need in the list.

Kindly help me out.
Thanks in anticipation.

Can you please paste your activity_main.xml? Moreso, it is preferable you use actionbar tabs.

Just changed position of layout and it stopped working
Clean and rebuild. Likely your resource ids in binary XML files and R.java are out of sync.
Now that you've included logcat, java.lang.ClassCastException: android.widget.ImageView cannot be cast to android.widget.TextView in detail() are also indicative of this - the resource ids you're passing to the method are valid TextViews but at least in one case it is referring to an ImageView in binary XML.

the mistake is in MyBaseAdapter.java
simple mistake, parameters mismatched.
insted of
private ImageView idetail(View v,int resId,int icon)
{
ImageView iv=(ImageView) v.findViewById(resId);
iv.setImageResource(resId);
return iv;
}
we need to change it to
private ImageView idetail(View v,int resId,int icon)
{
ImageView iv=(ImageView) v.findViewById(R.id.icon);
iv.setImageResource(icon);
return iv;
}
