why CardView causing slow down the scrolling process?

I was using listView without with the custom layout which is having
Linear layout as parent layout. Scrolling was fine, Then I need to
implement CardView for elevation and round corner, After implementation
list Scrolling become slow.Moreover it is also slowing down the
RecyclerView Process.
here is my xml.

Cardview is probably just the "breaking point" for how much graphic content that cna be used in an unoptimized way without lagging. As mentioned in some comments you should be using a ViewHolder, here is a simple example of using a viewholder:
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.list_entry, null);
holder = new ViewHolder();
holder.nameTextView = (TextView) convertView.findViewById(R.id.person_name);
holder.surnameTextView = (TextView) convertView.findViewById(R.id.person_surname);
holder.personImageView = (ImageView) convertView.findViewById(R.id.person_image);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
}
Person person = getItem(position);
holder.nameTextView.setText(person.getName());
holder.surnameTextView.setText(person.getSurname());
//holder.personImageView.setImageBitmap(person.getImage());
return convertView;
}
you can read more about it here
Additionally you should be using RecyclerView and not ListView, to optimize performance.

Try to minimize your view hierarchy and reduce complex operations from binding.

how to set the specific row item option(visible, invisible) in listview in android

frist my english skill weak.
description>
this is list view.
ㅡㅡㅡㅡㅡㅡㅡㅡ
ㅣㅡㅡㅡㅡㅡㅣㅢ <-- this is button , i init set invisible
ㅣㅡㅡㅡㅡㅡㅣㅢ
ㅣㅡㅡㅡㅡㅡㅣㅢ
ㅣㅡㅡㅡㅡㅡㅣㅢ
ㅣㅡㅡㅡㅡㅡ ////// <-- i want make visible button
ㅣㅡㅡㅡㅡㅡ ////// <-- specific position
I make the custom ListView
ListView row contains texts, Button.
The Button is set invisible option in xml file.
then, I want set the visible specific row button.
I tried that and failed
after make ArrayList for ListView, marking matching position like this
for(i=0; i<arraylist.size(); i++){
int t41=Integer.parseInt(arraylist.get(i).getm());
if(month == t41){
confirm_replay[i]=true;
temp55=i;
}
}
I can set the textValue. through adapter.getItem(int position).
but i don't know, how to control specific button.
also try add button into adapter. failed..
also search question in google but my eng skill bad. failed
add my code.

}

If you want to adjust a specific row, you can use the position parameter in your getView() method in adapter. For instance;
if(position==55){
holder.m.setVisibility(View.GONE);
}

I'm not sure i understand your question.
If i'm right you juste want your button to be invisble for specific row. To do so add the specific line at the end of your getView method
yourButton.setVisibility(View.INVISIBLE)
If you want to hide the entire row, the best way will probably be to change your adapter to diplay only row with content.

before setting the values to the view check the condition whatever you want like:-
if condition is true then set your view visible
else set your view invisible
if(true){
button.setVisibility(View.VISIBLE);
}else{
button.setVisibility(View.GONE);
}

Get "No results" Message Custom Adapter ListView Android

I am having a problem to set a "No results" message when getCount() returns 0.
I have a custom layout for the listview, and I simply want to get a "No Results" textview when there is no data on the listview.
Any idea how to achieve this?
I saw something with a empty id, but that needs to be on a listview, since this is a custom layout, it doesn't have that "tag".
Custom Adapter Code:
public class ListScheduleAdapter extends BaseAdapter {
Context context;
protected List<Schedule> listSchedules;
LayoutInflater inflater;
public ListScheduleAdapter(Context context, List<Schedule> listSchedules) {
this.listSchedules = listSchedules;
this.inflater = LayoutInflater.from(context);
this.context = context;
}
public int getCount() {
return listSchedules.size();
}
public Schedule getItem(int position) {
return listSchedules.get(position);
}
public long getItemId(int position) {
return listSchedules.get(position).getCod_Horario();
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = this.inflater.inflate(R.layout.layout_list_item,
parent, false);
holder.txtTeacher = (TextView) convertView
.findViewById(R.id.txt_teacher);
holder.txtDayofWeek = (TextView) convertView
.findViewById(R.id.txt_dayofweek);
holder.txtSubject = (TextView) convertView
.findViewById(R.id.txt_subject);
holder.txtTime = (TextView) convertView
.findViewById(R.id.txt_time);
holder.txtRoom = (TextView) convertView
.findViewById(R.id.txt_room);
holder.txtClass = (TextView) convertView
.findViewById(R.id.txt_class);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
Schedule sche = listSchedules.get(position);
String fullTeacher = sche.getProfessor();
String[] names = fullTeacher.split(" ");
holder.txtTeacher.setText(names[0] + " " + names[names.length-1]);
holder.txtDayofWeek.setText(sche.getDia_Semana());
holder.txtSubject.setText(sche.getDisciplina());
holder.txtTime.setText(sche.getT_Entrada() + "h-" + sche.getT_Saida()+"h");
holder.txtRoom.setText(sche.getSala());
holder.txtClass.setText(sche.getTurma());
return convertView;
}
private class ViewHolder {
TextView txtTeacher;
TextView txtDayofWeek;
TextView txtSubject;
TextView txtTime;
TextView txtRoom;
TextView txtClass;
}
}
Fragment Code (method called on a async OnPostExecute method):
private void populateListView() {
ListScheduleAdapter adapter = new ListScheduleAdapter(getActivity(), ScheduleList);
listviewHorarios.setAdapter(adapter);
}

add

android:visibility="gone" />
to the same layout where you declared your ListView (wrap both in a FrameLayout)
on the ListView's instance call
listView.setEmptyView(findViewById(R.id.empty));
when the adapter is empty, you will see the TextView apper

add TextView to your listview layout and setVisibility of it to GONE and check the adapter:
if(adapter==null){
listView.setVisiblity(View.GONE);
tvEmpty.setVisiblity(View.VISIBLE);
}
hope this will help.

Set different icons for each row

Above is the main screen of my app with a custom adapter for listview. How do I put a different icon for each row in the listview? I tried putting an ImageView in the xml but it overwrites my whole screen only showing an icon.
MainAcitivty xml:

Custom adapter:

public ImageView image;
}
public WeatherAdapter(Activity context, ArrayList<String> weatherData) {
super(context, R.layout.list, weatherData);
this.context = context;
this.weatherData = weatherData;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
// reuse views
if (rowView == null) {
LayoutInflater inflater = context.getLayoutInflater();
rowView = inflater.inflate(R.layout.list, null);
// configure view holder

Every row item has an image (imgThumb). This needs to be changed or set to a static image, depending on your needs. This is done in the adapters' getView() method.
imgThumb.setImageResource(R.drawable.my_image);

Private TypedArray img;
img=getResource.obtainTypedArray(R.array.imgIcon)
if (sa[position].startsWith("Air pressure")) {
rowView.setBackgroundResource(R.color.skyblue) ;
holder.image.setImageResource(img.gerResourceId[0]);
}else if (sa[position].startsWith("Air Condition")) {
holder.image.setImageResource(img.gerResourceId[1]);
}

Background of List items is stretching more than height?

I have a listview with a custom adapter (tile) design. Everything should work fine but the thing is that the til (listview item background) stretches too much despite me giving layout_height a fixed value. Here's the code:
This is the xml for the custom tile. Notice the 85dp fixed height. The background drawable should NOT stretch beyond this hight?
<?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="85dp"
android:background="#drawable/tile_job" >
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="9dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="13dp"
android:text="Title" />
<TextView
android:id="#+id/pickup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginTop="38dp"
android:layout_alignLeft="#+id/title"
android:textSize="11dp"
android:text="Pickup Address" />
<TextView
android:id="#+id/destination"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/pickup"
android:layout_below="#+id/pickup"
android:layout_marginTop="6dp"
android:textSize="11dp"
android:text="Destination Address" />
<TextView
android:id="#+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/destination"
android:layout_alignParentRight="true"
android:layout_marginRight="40dp"
android:text="Time"
android:textSize="11dp" />
<TextView
android:id="#+id/date"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/time"
android:layout_below="#+id/time"
android:text="Date"
android:layout_marginTop="7dp"
android:textSize="11dp" />
</RelativeLayout>
Now I'm using this in a simple listview:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/app_bg" >
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="#drawable/strip_top" >
<TextView
android:id="#+id/strip_text"
style="#style/TopStripText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="Locate" />
</RelativeLayout>
<RelativeLayout
android:layout_width="280dp"
android:layout_height="440dp"
android:layout_below="#+id/relativeLayout1"
android:layout_centerHorizontal="true"
android:layout_marginTop="15dp"
android:background="#drawable/bg_booking" >
<ListView
android:id="#+id/activebookings"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
</ListView>
</RelativeLayout>
What is causing the tile to overstretch vertically?
===========
EDIT
Here is the requested code:
Inflation of the layout:
public class JobAdapter extends BaseAdapter
{
private ArrayList<Job> bookingArrayList;
private LayoutInflater mInflater;
public JobAdapter(Context context, ArrayList<Job> results)
{
bookingArrayList = results;
mInflater = LayoutInflater.from(context);
}
#Override
public int getCount()
{
return bookingArrayList.size();
}
#Override
public Object getItem(int arg0)
{
return bookingArrayList.get(arg0);
}
#Override
public long getItemId(int position)
{
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
ViewHolder holder;
if (convertView == null)
{
convertView = mInflater.inflate(R.layout.tile_job, null);
holder = new ViewHolder();
holder.date = (TextView) convertView.findViewById(R.id.date);
holder.time = (TextView) convertView.findViewById(R.id.time);
holder.pickup = (TextView) convertView.findViewById(R.id.pickup);
holder.destination = (TextView) convertView.findViewById(R.id.destination);
holder.title = (TextView) convertView.findViewById(R.id.title);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.date.setText(bookingArrayList.get(position).getDate());
holder.time.setText(bookingArrayList.get(position).getTime());
holder.pickup.setText(bookingArrayList.get(position).getPickup());
holder.destination.setText(bookingArrayList.get(position).getDestination());
holder.title.setText(bookingArrayList.get(position).getTitle());
return convertView;
}
static class ViewHolder
{
TextView date;
TextView time;
TextView pickup;
TextView destination;
TextView title;
}
}

Your creating you row with following:
convertView = mInflater.inflate(R.layout.tile_job, null);
Now try this:
convertView = mInflater.inflate(R.layout.tile_job, parent, false);
If you don't attach the parent layout the layout parameters from xml will be ignored. You set false as you don't attach the view to the root right away (this happens automatically when the view is returned). You can read more about this issue here.
