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;

#Override

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));

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"/>
In my app I have a listview in a tab fragment. Each row of listview is a cardview , which has multiple views in it.(Buttons, textviews etc.) I have created a custom adapter class for this listview.
This adapter class takes the data from local DB and inserts it in different views in cardview, creating a list of cards. I have a like button in cardview.
Now, when user presses the like button, I'm changing the background of button with a onClickListener on button in adapter class.
The problem is, if I press like button on one card, it will change the background of like button on that card as well as like button on forth card down in the list. I think this has to do something with ViewHolder pattern I'm using, but not sure how to fix it.
Here is the Custom Adapter class

map.put(position,"like");
holder.like.setOnClickListener(new View.OnClickListener() { //this method has the problem
#Override
public void onClick(View v) {
if (post.postlikeflag == 0 && map.get(position).equals("like")) {
holder.like.setBackgroundResource(R.drawable.liked);
map.put(position,"liked");
post.postlikeflag =1;
} else {
holder.like.setBackgroundResource(R.drawable.like);

}
}
});
holder.postdetail.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent eventDetail = new Intent(context, PostDetailActivity.class);
eventDetail.putExtra("EventDetail", post);
context.startActivity(eventDetail);
}
});
In your button and other view where onClick listener is there add these two line in xml
android:focusable="false"
android:focusableInTouchMode="false"
declare final variable index as below and initialize it with position at very
start of getView method as below
final int index = position;
Also on click instead of this
post.postlikeflag =1;
try this
data.get(index).postlikeflag = 1;
also you will have to call notifyDataSetChanged()
I got it working by using HashMap as SAM suggested.
Here is what I did.
in Adapter class
HashMap<Long, String> map = new HashMap<Long, String>();
in getView()method of adapter
if(post.postlikeflag==0){
map.put(post.postid, "like");
}
else{
map.put(post.postid,"liked");
}
if(map.get(post.postid).equals("like")) {
holder.like.setBackgroundResource(R.drawable.like);
}
else {
holder.like.setBackgroundResource(R.drawable.liked);
}
And in onclickListener of like button
if (post.postlikeflag == 0 && map.get(post.postid).equals("like")) {
holder.like.setBackgroundResource(R.drawable.liked);
map.put(post.postid, "liked");
post.postlikeflag = 1;
} else {
holder.like.setBackgroundResource(R.drawable.like);
post.postlikeflag = 0;
map.put(post.postid,"like");
}
I know there can be some redundancy in the code. Point it out if you find.
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.
MyBaseAdapter is for the adapter needed to load data in listview.

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;
}
