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.

listview is not clickable after adding custom adapter android

i want get image from the listview .But problem is that whatever the list view i created that is not clickable. i tried with onItemclick listener also, but its not working because of listview is not clickable . Its seems that listview is not at all clickable ..Below is given adapter for for listview.
// The adapter of the GridView which contains the details of the detected faces.
private class FaceListAdapter extends BaseAdapter {
//List<FaceRectangle> ffRect;
// The detected faces.

// Crop face thumbnail with five main landmarks drawn from original image.
faceThumbnails.add(ImageHelper.generateFaceThumbnail(mBitmap, face.faceRectangle));
faceRect=face.faceRectangle;
//ffRect.add(faceRect);
faceIdList.add(null);
} catch (IOException e) {
// Show the exception when generating face thumbnail fails.

The isEnabled method on your adapter is responsible for your ListView ignoring clicks.
#Override
public boolean isEnabled(int position)
{
return false;
}
Your adapter overrides isEnabled and returns false for all positions, indicating that every item in the list is disabled. Disabled views do not receive input events.
If its possible to disable items in your list then your custom adapter needs to track these items somehow (e.g. a list), otherwise you should be returning true for all positions.

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;
}
}

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.

Even scrolling is not working.
I am unable to figure out why is this happening? Am I missing out something?
Any help in resolving this is appreciated.

The following will do the job in your case.
ListView propertylistview = (ListView) findViewById(R.id.listview);
propertylistview.setOnItemClickListener( myListViewClicked ):
OnItemClickListener myListViewClicked = new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(YourActivity.this, "Clicked at positon = " + position, Toast.LENGTH_SHORT).show();
}
};
Dont forget to remove the following from the CustomAdapter
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(parent.getContext(), "view clicked: " + ListArray.getName(), Toast.LENGTH_SHORT).show();
}
});

If the touch events are getting intercepted inside the cell layout, in the layout for your custom cell, set
android:descendantFocusability="blocksDescendants" on the top level layout of your cell. For me, it was too much of a pain to add xml attributes to every individual view.
Note that this can also be set in code:
cell.setDescendantFocusability(FOCUS_BLOCK_DESCENDANTS);
I also tried this with a ListView inside a cell, and I had to override onTouchEvent to get it to work:
public class NoTouchListView extends ListView {
#Override
public boolean onTouchEvent(MotionEvent ev) {
return false;
}
}

the simple code that solved my problem, and method view.setOnClickListener be within my custom adapter
view.setFocusable(false)

Check your list row layout once :
layout or any view should not be `android:clickable="true" and
android:focusable="true"
if it is there just delete and run the application again.

Even I was having the same problem, I am having checkbox, did the following to masker itemClickListener work,
Added the following properties to the checkbox,
android:focusable="false"
android:focusableInTouchMode="false"
android:clickable="false"
and ItemClickListner started working.

Hope it helps Cheers!!

For TextView you should also use
android:textIsSelectable="false"

ListView Rowlayout in a own coded Chat

What I'm trying to do
I'm trying to create a chat which has to diffrent row's. For every row I made a own layout file, but the problem is that the layoutfile of one row dosn't fit the screen.
Question
What do I need to change in the row layout that it fits like it should. You'll find the code and also a printscreen of what I'm trying.
Code
ListAdapter
public class ChatListAdapter extends BaseAdapter {
private ArrayList<String> ContentList;
private ArrayList<Integer> ChatUserList;
private static LayoutInflater inflater = null;
public ChatListAdapter(Activity activity, ArrayList<String> _ContentList,
ArrayList<Integer> _ChatUserList) {
ContentList = _ContentList;
ChatUserList = _ChatUserList;
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return ContentList.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
TextView tv_text;
TextView tv_date;
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
if (ChatUserList.get(position) == 1) {
// I'm RECIVER -> Message is left align
vi = inflater.inflate(R.layout.rowlayout_leftalign, null);
tv_text = (TextView) vi.findViewById(R.id.tv_chat_leftalign);
tv_date = (TextView) vi.findViewById(R.id.tv_chat_leftalign_date);
} else {
// I'm SENDER -> Message is right align
vi = inflater.inflate(R.layout.rowlayout_rightalign, null);
tv_text = (TextView) vi.findViewById(R.id.tv_chat_rightalign);
tv_date = (TextView) vi.findViewById(R.id.tv_chat_rightalign_date);
}
tv_date.setText(sdf.format(new Date()));
tv_text.setText(ContentList.get(position));
tv_text.setMaxWidth(((Chat.display.getWidth() / 4) * 3));
return vi;
}

for both XML add android:layout_width="fill_parent" and android:layout_height="wrap_content" like followings
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:background="#android:color/transparent"
android:layout_height="wrap_content"
android:layout_width="fill_parent" >
and so on...
