ListView in android scroll very slow when they take a short place

Please, the listview with just 3 textview (there is no image) it was working very fine when it was taking the full screen in height and width.
and after i have been change it to take the half of screen in height, it became scrolling very slow.
layout for rows in listView
<?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="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginStart="16dp"
android:layout_marginTop="8dp"
android:layout_marginBottom="4dp"
android:layout_marginEnd="16dp"
android:layout_toStartOf="#id/timer_row">
<TextView
android:id="#+id/name_row"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold"
android:textSize="#dimen/main_title_size"

and the adapter with the viewholder
public class MusicAdapter extends BaseAdapter {
private ArrayList<Music> list;
private LayoutInflater layoutInflater;
MusicAdapter(Context context, ArrayList<Music> list) {
this.list = list;
layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return list.size();
}
#Override
public Object getItem(int position) {
return list.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.music_row, parent, false);
viewHolder = new ViewHolder(convertView);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
Music music = (Music) getItem(position);
viewHolder.title.setText(music.getName());
viewHolder.author.setText(music.getAuthor());
viewHolder.timer.setText(music.getTimer());
return convertView;
}
static class ViewHolder{
TextView title,author,timer;
ViewHolder(View v)
{
this.title = v.findViewById(R.id.name_row);
this.author = v.findViewById(R.id.author_row);
this.timer = v.findViewById(R.id.timer_row);
}
}
}

You should try to use RecyclerView instead of ListView: https://developer.android.com/guide/topics/ui/layout/recyclerview

Animate button inside custom adapter for listview

I made a ListView with a custom adapter with my own layout, and on this layout there is a text view, a button and three image buttons that are at first with setVisibility.GONE
I am trying to animate this button for when the user clicks on it, it changes its position from right to left to give space for the three image buttons.
The problem is, the only item in which the animation is working is the last item on the list. I want the animation to work in all of the items.
Here's the code for my adapter:
public class ListaAdapter extends BaseAdapter implements ListAdapter {
private ArrayList<String> list = new ArrayList<String>();
private Context context;
private ListView lista;
private Button btnAbrir;
private RelativeLayout relativeLayout;
private ObjectAnimator animation;
public ListaAdapter (ArrayList<String> list, Context context, ListView a) {
this.list = list;
this.context = context;
this.lista = a;
}
#Override
public int getCount() {
return list.size();
}
#Override
public Object getItem(int pos) {
return list.get(pos);
}
#Override
public long getItemId(int pos) {
return 0;
//just return 0 if your list items do not have an Id variable.
}
#Override
public View getView(final int position, View convertView, ViewGroup
parent)
{
View view = convertView;
if (view == null) {
LayoutInflater inflater = (LayoutInflater)
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.custom_list, null);
}
TextView listItemText = (TextView)view.findViewById(R.id.textoItem);
listItemText.setText(list.get(position));
final LinearLayout btnLayout = (LinearLayout)
view.findViewById(R.id.btnLayout);
relativeLayout = (RelativeLayout) view.findViewById(R.id.layout);
btnAbrir = (Button)view.findViewById(R.id.btnAbrir);
ImageButton btnNaoSei = (ImageButton)view.findViewById(R.id.btnNaoSei);
ImageButton btnAceitar =
(ImageButton)view.findViewById(R.id.btnAceitar);
ImageButton btnNegar = (ImageButton)view.findViewById(R.id.btnNegar);
animation = ObjectAnimator.ofFloat(btnAbrir,"x",200);
btnLayout.setVisibility(View.GONE);
btnAbrir.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
btnLayout.setVisibility(View.VISIBLE);
animate();
}
});
return view;
}
private void animate()
{
animation.setDuration(500);
animation.start();
}
}

Any idea on how to accomplish this? Thanks in advance.

The things you need to adopt the following method and create a ViewHolder so that your adapter will know each element of each row in the List
The last UI element of the row only animates because this the only last known id of components for your Adapater when he was creating the Views in your List. So it will animates for the last row elements
You have to add ViewHolder nested class inside your Adapter and declare your UI components. Use setTag and getTag methods inside the getView
Overall you have to create your adapter things like this in getView
public class SListAdapter extends ArrayAdapter<String> {
private Context context;
private String[] seCtnColors;
private List<Subscription> item;
private ViewHolder mainViewHolder = null;
private ViewHolder viewHolder;
private LayoutInflater inflater;
private View row;
public SListAdapter(Context c, List<Subscription> subscriptions)
{
super(c, R.layout.row,R.id.rowNameTV);
this.context=c;
this.item = subscriptions;
}
#Override
public int getCount() {
return this.item.size();
}
#Override
public View getView(final int position, final View convertView, ViewGroup parent) {
row = null;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.row,parent,false);
viewHolder = new ViewHolder();
initAdapterUI();
setAdapterDataset(position);
return row;
}
private void initAdapterUI() {
viewHolder.animatedGifViewHol = row.findViewById(R.id.row_animated_gif);
viewHolder.alertBarVerticalViewHol = row.findViewById(R.id.alertBarVerticalView);
viewHolder.firstNameTVHol = (TextView) row.findViewById(R.id.rowNameTV);
viewHolder.phoneNumberTVHol = (TextView) row.findViewById(R.id.rowNumberTV);
viewHolder.switchStateTVHol = (TextView) row.findViewById(R.id.switchStateTV);
row.setTag(viewHolder);
}
private void setAdapterDataset(int position) {
mainViewHolder = (ViewHolder) row.getTag();
mainViewHolder.alertBarVerticalViewHol.setBackgroundColor(Color.RED);
mainViewHolder.switchStateTVHol.setTextColor(Color.RED);
mainViewHolder.firstNameTVHol.setText(item.get(position).getFirstName());
mainViewHolder.phoneNumberTVHol.setText(item.get(position).getNumber());
}
public class ViewHolder{
View animatedGifViewHol;
View alertBarVerticalViewHol;
TextView firstNameTVHol;
TextView switchStateTVHol;
TextView phoneNumberTVHol;
}
}

ListView with BaseAdapter and LinearLayout?

I'm trying create a BaseAdapter to my ListView. The problem is when I do create a LinearLayout inside other LinearLayout the listener OnItemClickListener doesn't works. If I put the components outside of LinearLayout works fine.
How could I do this works ?

It seems your CheckBox is stealing the focus.
Try setting these properties on it:
android:focusable="false"
android:focusableInTouchMode="false"
android:clickable="false"

Android GridView not showing items

I have made an app with a gridview by following slidenerd's tutorial. My problem is that I can see the view but it's empty. When I move my finger I can see the top and the button becoming blue.

ListView is showing gapes in list items Android

i am trying to implement listView through setListAdapter and Efficient Adapter. I want that when list is show then the background should not be repeat. My code is repeating the whole layout of list.xml due to which my list item are showing with so much gap.
Right now my list is working like that:
But i want this type of view:
Here is my editText.xml in which i type the word and a list View is opened.
<EditText
android:id="#+id/start_edit"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_gravity="top|left"
android:ems="10"
android:hint="Type to search"
android:paddingLeft="50dp" >
<requestFocus />
</EditText>
this layout is for list.xml :
<RelativeLayout
android:id="#+id/RelativeLayout_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/blue_cellbar" >
the list.xml file is repeating the layout in Effecient adapter:
here is my code:
listAdapter = new EfficientAdapter2(this);
setListAdapter(listAdapter);
public static class viewHolder2 {
TextView word;
TextView meaning;
ImageView image;
ImageView image_color;
RelativeLayout cell;
}
private class EfficientAdapter2 extends BaseAdapter implements Filterable,OnItemClickListener {

public EfficientAdapter2(Context context) {
this.context = context;
inflater = LayoutInflater.from(context);
}
public int getCount() {
// if(SearchWordString.isEmpty()==false)
// {

/// }
//return 0;
}

return position;
}

return position;
}

I hope you have not provide android:dividerHeight attribute in your layout file under <ListView/>
If so please remove it.

this problem occurs when you have set the adapter class xml, parent root
match_content instead of wrap_content.
set the root content height wrap_content
As i can see in adapter layout there is no parent root like relative, linearlayout, Framelayout and ConstraintLayout etc.
