I have a listview and it is properly arranged. I need to add column title. Below i have posted the display.xml file which handles the listview arrangments. But there is no title.
Display.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#F3CAE5"
android:gravity="center_vertical"
android:orientation="horizontal"
android:padding="8dp" >
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textColor="#000"
android:text="Ser No."/>
<TextView
android:id="#+id/id"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textColor="#000" />
<TextView
android:id="#+id/name"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2"
android:textColor="#000" />
<TextView
android:id="#+id/add"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2"
android:textColor="#000" />
</LinearLayout>
ListView.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<include layout="#layout/header"/>
<ListView
android:id="#+id/list"
android:layout_height="wrap_content"
android:layout_width="match_parent">
</ListView>
</LinearLayout>
ShowData.java
import android.app.ListActivity;
import android.database.Cursor;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ListView;
/**
* Created by Akash on 3/13/2016.
*/
public class ShowData extends ListActivity {
private VivzHelper helper;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
VivzHelper empClick = new VivzHelper(getApplicationContext());
Cursor cursor = empClick.getDetails();
if (cursor != null)
getListView().setAdapter(
new android.support.v4.widget.SimpleCursorAdapter(this, R.layout.display, cursor, new String[]{
"_id", "Name", "Address"
}, new int[]{R.id.id, R.id.name, R.id.add}, 0));
}
}
If you want to show a title on top of your listView you could use a header. Instead of including the header layout above your listView, remove it. Leave it in another xml resource (header.xml).
And then when you set the adapter, add also the header to your list like this
ListView listView = getListView();
View header = getLayoutInflater().inflate(R.layout.header, null);
listView.addHeaderView(header);
listView.setAdapter(new android.support.v4.widget.SimpleCursorAdapter(this, R.layout.display, cursor, new String[]{
"_id", "Name", "Address"
}, new int[]{R.id.id, R.id.name, R.id.add}, 0));
(I suppose that in your method getListView() you are doing something like
private ListView getListView(){
return ListView listView = (ListView) findViewById(R.id.list);
}
This should be your list.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/list"
android:layout_height="wrap_content"
android:layout_width="match_parent">
</ListView>
</LinearLayout>
And the header.xml will be another layout where you can define whatever you want to appear on top of your list. If you want three columns
<LinearLayout
android:id="#+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/textView1"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Street"
android:layout_gravity="left"
android:background="#88FF0000"/>
<TextView
android:id="#+id/textView2"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="number"
android:layout_gravity="right"
android:background="#8800FF00"/>
<TextView
android:id="#+id/textView3"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="name"
android:layout_gravity="right"
android:background="#8800FF00"/>
</LinearLayout
You can do that with RecyclerView.Adapter.
RecyclerView.Adapter has getItemViewType() function.
Example
#Override
public int getItemViewType(int position)
{
if(position == 0)
return LIST_HEADER;
else if(position > 0)
return LIST_ITEM;
return -1;
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
{
if (viewType == LIST_HEADER)
{
View view = LayoutInflater.from(mContext).inflate(R.layout.your_header_layout, parent, false);
return view;
}
else if (viewType == LIST_ITEM)
{
View view = LayoutInflater.from(mContext).inflate(R.layout.your_item_layout, parent, false);
return view;
}
return null;
}
change your Display.xml name to header.xml............
then add layout using include..
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<include layout="#layout/header"/>
<ListView
android:id="#+id/list"
android:layout_height="wrap_content"
android:layout_width="match_parent">
</ListView>
</LinearLayout>

} else {
holder = (ViewHolder) convertView.getTag();
}
holder.t1.setText(titlelist.get(position));
holder.t2.setText(datalist.get(position));
return convertView;
}
}
you have to add this functionality in your adapter,
#Override
public View getView(int position, View convertView, ViewGroup parent) {
//ur other codes.....
//
//
if(crossButtonPress){
holder.imageView.setImageResource(R.drawable.cross);
}else{
holder.imageView.setImageResource(R.drawable.default_ic);
}
}
In addition, in you actual button's onClick,
crossButtonPress = true;
adapter.notifyDatasetChanged();
In the below code how to scroll not just the ListView, but all of the Views with it? If I am adding full page scrollview then listview not showing full page.
But top menu should be constant. Inside search button I want to scroll full list.

Use this function to full view list on scroll view.
ListView listViewObject;
// after binding list view.
getListViewSize(listViewObject);// pass your listview object here.
public void getListViewSize(ListView myListView) {
ListAdapter myListAdapter = myListView.getAdapter();
if (myListAdapter == null) {
//do nothing return null
return;
}
//set listAdapter in loop for getting final size
int totalHeight = 0;
for (int size = 0; size < myListAdapter.getCount(); size++) {
View listItem = myListAdapter.getView(size, null, myListView);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
//setting listview item in adapter
ViewGroup.LayoutParams params = myListView.getLayoutParams();
params.height = totalHeight + (myListView.getDividerHeight() * (myListAdapter.getCount() - 1));
myListView.setLayoutParams(params);
// print height of adapter on log
Log.i("height of listItem:", String.valueOf(totalHeight));
}
Hope! it is helpful to you...
You should copy the layouts, you want to scroll with the listview in a different layout XML and put it to the top of the listview as a different first item. You can do it with a custom ListAdapter:
//WARNING: I did not try this code, handle it like pseudocode
private class MyCustomAdapter extends BaseAdapter {
private ArrayList<Item> mData = new ArrayList<>();
private LayoutInflater mInflater;
public MyCustomAdapter() {
mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void addItem(final Item item) {
mData.add(item);
notifyDataSetChanged();
}
#Override
public int getCount() {
return mData.size() + 1;
}
#Override
public Item getItem(int position) {
return mData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if(position==0){
//initialize your custom view
}else{
//initialize a normal list item
}
return convertView;
}
}
Check this ListAdapter example, if you still have questions!

How to display a two column ListView in Android?

Closed 7 years ago.
Hi I'd like to made a 2 vertical listview to show some data from server.
But it's getting a lot of errors..
Please help me to fix it.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<TextView android:id="#+id/data"

</LinearLayout>
What I'm after:
I will give you an answer that resembles what you want, but you are free to tweak it.
Just to note: RecyclerView is mostly used nowadays, but since you asked for a ListView example I will give you an example with a ListView.
First of all you need to specify one ListView in your main activity's layout xml file. You also need a second layout for each item in the ListView. This second layout is going to have two TexViews. The first for Date and the second for Result. And finally you need an adapter for that ListView, which is responsible for inflating each item's (of the list) layoout, keep your list data, etc.
Here is a sample activity_main.xml layout. I added two views to resemble the lines between TextViews:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp"
tools:context=".MainActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/relativeLayout" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Date"
android:id="#+id/textViewDate"
android:gravity="center"
android:layout_toLeftOf="#+id/view2"
android:layout_toStartOf="#+id/view2"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#android:color/darker_gray"
android:id="#+id/view1"
android:layout_alignBottom="#+id/textViewDate" />
<View
android:layout_width="1dp"
android:layout_height="match_parent"
android:background="#android:color/darker_gray"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:id="#+id/view2"
android:layout_alignBottom="#+id/textViewDate" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Result"
android:id="#+id/textViewResult"
android:gravity="center"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_toRightOf="#+id/view2"
android:layout_toEndOf="#+id/view2" />
</RelativeLayout>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/listView"
android:layout_below="#+id/relativeLayout">
</ListView>
</RelativeLayout>
The list_item.xml layout for each item in the list:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Date"
android:id="#+id/textViewDate"
android:gravity="center"
android:layout_toLeftOf="#+id/view"
android:layout_toStartOf="#+id/view"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<View
android:layout_width="1dp"
android:layout_height="match_parent"
android:background="#android:color/darker_gray"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:id="#+id/view"
android:layout_alignBottom="#+id/textViewDate" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Result"
android:id="#+id/textViewResult"
android:gravity="center"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_toRightOf="#+id/view"
android:layout_toEndOf="#+id/view"
android:layout_alignBottom="#+id/textViewDate" />
</RelativeLayout>
Then a class for your custom item that holds a date and a result.
public class MyItem {
public GregorianCalendar date;
public String result;
public MyItem(GregorianCalendar date, String result){
this.date = date;
this.result = result;
}
}
and the adapter (here ArrayAdapter):
public class MyAdapter extends ArrayAdapter<MyItem> {
private final Context mContext;
private MyItem[] mItems;
public MyAdapter(Context context, MyItem[] items) {
super(context, -1, items);
mContext = context;
mItems = items;
}
#Override
public View getView(int position,View view,ViewGroup parent) {
View rowView = view;
if (rowView == null) {
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = inflater.inflate(R.layout.list_item, null, true);
}
TextView textViewDate = (TextView) rowView.findViewById(R.id.textViewDate);
TextView textViewResult = (TextView) rowView.findViewById(R.id.textViewResult);
textViewDate.setText(mItems[position].date.getTime().toString());
textViewResult.setText(mItems[position].result);
return rowView;
}
}
Finally in your activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MyItem[] items = {new MyItem(new GregorianCalendar(2014, 1, 1), "Ok"),
new MyItem(new GregorianCalendar(2014, 2, 3), "Not ok"),
new MyItem(new GregorianCalendar(2015, 3, 3), "Ok"),
new MyItem(new GregorianCalendar(2015, 5, 7), "Warning"),
new MyItem(new GregorianCalendar(2016, 7, 1), "Ok")};
MyAdapter adapter = new MyAdapter(this, items);
ListView listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(adapter);
}
I have the following code that is a dynamic listview where you type in the textbox and click the add button and its added to the listview below. Listview is a custom listview with 2 textviews. Somehow the code adds the first item and then does not add the rest. The arraylist gets the item, i call adapter.notifyDataSetChanged(); and yet still the listview does not get updated. What am i doing wrong?

As you can see in documentation to SimppleAdapter it is
An easy adapter to map static data to views defined in an XML file.
I believe that you can find any tricky way to add data dynamically. But I'm not sure that you have to do it like this. Try to use ArrayAdapter instead. By default it binds T.toString() values to single TextView, but you can override getView(int, View, ViewGroup) to return the type of view you want.
I changed the main xml file as follows
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/LinearLayout02"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/txtAddComplaint"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" >
</EditText>
<Button
android:id="#+id/btnAddComplaint"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add to Listview" >
</Button>
</LinearLayout>
<ListView
android:id="#+id/lvComplaintsList"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
I had used a table layout and the listview was in one of the rows.
Hope this helps someone .
I want to be able to click on a button inside an item of a ListView. It should have a different effect from clicking the whole item. I realize there are several questions asked on stackoverflow, but none of the suggestions works for me.
The ListView is inside a Fragment.
Layout of the fragment:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".EventFragment" >
<ListView
android:id="#+id/event_list"
android:background="#C0FFFFFF"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="5dp" />
</RelativeLayout>
Layout of each list item:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"

My list adapter is:
public class EventAdapter extends ArrayAdapter<Event> {
static class ViewHolder {
TextView separator;
LinearLayout relativeLayout;
TextView eventHeader;
TextView eventDescription;
ImageView blueDot;
Button button1;
Button button2;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater)
_context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.event_list_item, parent, false);
viewHolder = new ViewHolder();
viewHolder.relativeLayout = (LinearLayout) convertView.findViewById(R.id.event_list_element);
viewHolder.blueDot = (ImageView) convertView.findViewById(R.id.event_list_element_icon);
viewHolder.eventHeader = (TextView) convertView.findViewById(R.id.event_list_element_firstLine);
viewHolder.eventDescription = (TextView) convertView.findViewById(R.id.event_list_element_secondLine);
viewHolder.button1 = (Button) convertView.findViewById(R.id.event_list_element_button1);
viewHolder.button2 = (Button) convertView.findViewById(R.id.event_list_element_button2);
viewHolder.separator = (TextView) convertView.findViewById(R.id.event_list_separator);
convertView.setTag(viewHolder);
} else{
viewHolder = (ViewHolder) convertView.getTag();
}
final Event item = getItem(position);
if (item != null) {
OnClickListener listener = new OnClickListener() {
#Override
public void onClick(View arg0) {
Toast.makeText(_context, "boo!", Toast.LENGTH_SHORT).show();
}
};
viewHolder.button1.setOnClickListener(listener);
}
return convertView;
}
}
The problem is that the two buttons are not clickable. What I tried to far:
ListView listView = (ListView) rootView.findViewById(R.id.event_list);
listView.setItemsCanFocus(true);
I also tried setting on the button:
android:focusable="true"
android:clickable="true"
I also experimented with android:descendantFocusability.
None of my tries made the buttons clickable.
Insert the attribute android:descendantFocusability="blocksDescendants" in the Parent Layout declaration of each list item.
The xml should be as follows:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:background="#C0101010">

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="separator"
android:textColor="#android:color/white" />
<LinearLayout
android:id="#+id/event_list_element"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#FFFFFFFF"
android:padding="6dip" >

android:layout_width="26dip"
android:layout_height="60dip"

I found the solution! I wanted to update the list of events periodically (right now it's a thread running every x milliseconds, later I want to switch that to only update the event list when there is a change). Anyway, the code was (inside my main activity):
private BroadcastReceiver _bReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals(RECEIVE_EVENT)) {
Bundle bundle = intent.getExtras();
Event event = (Event) bundle.get("event");
showEvent(event);
}
}
};
private void showEvent(final Event event){
final Context context = this;
runOnUiThread(new Runnable() {
public void run() {
final ListView listview = (ListView) findViewById(R.id.event_list);
EventAdapter adapter = new EventAdapter(context, id.event_list, getEventList());
listview.setAdapter(adapter);
}
});
}
Setting the adapter each time is certainly not the right approach. Once I changed that to only set the adapter once, it worked like suggested using android:descendantFocusability="blocksDescendants"
