Listview displays only one row from the list

I am new to android listviews and I am trying to populate a listview in android by a list of items coming from a webservice. I know that the list contains more than one record coming from the webservice but my custom listview displays only the first record from the list. I checked the size of the list and there is always more than one records but the listview is showing only one of them. My custom adapter is like following:
public class ListAdapter extends BaseAdapter {
Context ctx;
LayoutInflater lInflater;
ArrayList<LItem> lstItems;
ListAdapter(Context context, ArrayList<LItem> objects) {
ctx = context;
lstItems = objects;
lInflater = (LayoutInflater) ctx
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return lstItems.size();
}
#Override
public Object getItem(int position) {
return lstItems.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
view = lInflater.inflate(R.layout.list_style_task
, parent, false);
}
LItem p = getProduct(position);
((TextView) view.findViewById(R.id.tvMaterial )).setText(p.getMName() );
((TextView) view.findViewById(R.id.tvTask )).setText(p.getTName() );
((TextView) view.findViewById(R.id.tvBQuantity )).setText(p.getBQ() );
// CheckBox cbBuy = (CheckBox) view.findViewById(R.id.checkbox);
//cbBuy.setOnCheckedChangeListener(myCheckChangList);
// cbBuy.setTag(position);
// cbBuy.setChecked(p.selected);
return view;
}
LItem getProduct(int position)
{
return ((LItem) getItem(position));
}
ArrayList<LItem> getBox() {
ArrayList<LItem> box = new ArrayList<LItem>();
for (LItem p : lstItems) {
// if (p.selected)
// box.add(p);
}
return box;
}
OnCheckedChangeListener myCheckChangList = new OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
//getProduct((Integer) buttonView.getTag())= isChecked;
}
};
}
I am binding the listview as:
protected void onPostExecute(List<LItem> li ) {
super.onPostExecute(lstItm);
if(lstItm.size()>0) {
Adp=new ListAdapter(myactivity,lstItm);
lvTasks.setAdapter(Adp);
Log.d("Size---------",Integer.toString(lstItm.size()) );//here it writes more than one as size of the list.
}
}
My xml file for displaying lists is like this:

and it worked for me :)

I guess the problem is with your layout Listview xml you are using relative layout they will obviously overlap each other until or unless you place them relative to each other.
You have to take out your lv_song_list from indexer_layout

Button inside ListView not clickable

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"

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"

can anybody help me to inflate the list to flipper.

it is simple.just put this code.
storeList = (ListView) inflater.inflate(R.layout.store_list, null);
it is working

android -> relative-layout changes button text alignment on click

This is my main.xml:`

After I press one of the buttons its text alignment goes to the left, how can I make it stay in center?
something similar happens with the first table (header) (textview1, textview2) but here it also reduses the textsize the amount of the text in the view...
EDIT: I managed to find the code that causes the change but I don't know how to fix this.
Maybe some one can explain me why does this happen and how to fix it?
private void fillTableView(List<BatteryInfo> list) {
TextView leftHeader = (TextView) findViewById(R.id.leftHeader);
TextView rightHeader = (TextView) findViewById(R.id.rightHeader);
LayoutParams leftHeaderLayoutParams = leftHeader.getLayoutParams();
LayoutParams rightHeaderLayoutParams = rightHeader.getLayoutParams();
TableLayout contentTable = (TableLayout) findViewById(R.id.maintable);
contentTable.removeAllViews();
for (int i = list.size() - 1; i >= 0; i--) {
TextView tv1 = new TextView(this);
tv1.setTextColor(Color.BLACK);
tv1.setGravity(Gravity.CENTER);
tv1.setBackgroundColor(Color.LTGRAY);
tv1.setLayoutParams(leftHeaderLayoutParams);
tv1.setText(String.valueOf(list.get(i).getLevel()));
TextView tv2 = new TextView(this);
tv2.setTextColor(Color.BLACK);
tv2.setGravity(Gravity.CENTER);
tv2.setBackgroundColor(Color.WHITE);
tv2.setLayoutParams(rightHeaderLayoutParams);
tv2.setText(list.get(i).getDurationTimeInString());
TableRow tblRow = new TableRow(this);
tblRow.addView(tv1);
tblRow.addView(tv2);
contentTable.addView(tblRow);
}
}
After I use removeAllViews or any addView function the layout of the top most table changes as I explained before. Why does this happen?

You can fix this by changing the android:layout_width="30dip" and android:layout_width="70dip" in leftHeader and rightHeader to android:layout_width="fill_parent". I have to admit that I'm not entirely certain why that is, though.
Instead of clearing and re-filling a TableLayout every time, though, you might want to consider using a ListAdapter. It's much more suited to what you're doing (and will probably perform better, too).
UPDATE NUMBER 2:
Notice the change in the main.xml and the change in the onCreate method. This will make your header static while letting your listview scroll, and changing from TableLayout to LinearLayout for your buttons will fix the alignment issue.
Here's how to do this with a custom adapter instead of TableLayout (which isn't really meant for dynamic data like this):
Change you main.xml to this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:addStatesFromChildren="false" android:layout_height="wrap_content">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_alignParentTop="true" android:id="#+id/header">
<TextView android:id="#+id/leftHeader" android:textColor="#android:color/black"
android:layout_margin="1dp" android:gravity="center_horizontal"
android:layout_weight="1" android:background="#ffcccccc" android:text="textview1"
android:layout_width="fill_parent" android:layout_height="wrap_content"/>
<TextView android:id="#+id/rightHeader" android:textColor="#android:color/black"
android:gravity="center_horizontal" android:layout_weight="1"
android:layout_margin="1dp" android:background="#android:color/white"
android:text="textview2" android:layout_width="fill_parent" android:layout_height="wrap_content"/>
</LinearLayout>
<LinearLayout android:id="#+id/buttonTable" android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:background="#android:color/black"
android:layout_alignParentBottom="true" >
<Button android:id="#+id/button_ResetData"
android:layout_height="wrap_content" android:layout_width="fill_parent"
android:text="Reset Data" android:layout_gravity="center"
android:layout_weight="1" />
<Button android:id="#+id/button_Refresh"
android:layout_height="wrap_content" android:layout_width="fill_parent"
android:text="Refresh" android:gravity="center"
android:layout_weight="1" />
</LinearLayout>
<ListView android:id="#+id/listView" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_weight="1"
android:fadingEdge="none"
android:layout_below="#id/header" android:layout_above="#id/buttonTable">
</ListView>
Add XML layout files for your rows (row.xml):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content">
<TextView android:id="#+id/maintableLeft"
android:layout_height="wrap_content" android:layout_weight="1"
android:layout_marginRight="1dp" android:layout_marginLeft="1dp"
android:gravity="center_horizontal" android:background="#ffcccccc"
android:textColor="#android:color/black" android:layout_width="fill_parent" />
<TextView android:id="#+id/maintableRight"
android:layout_height="wrap_content" android:background="#ffcccccc"
android:textColor="#android:color/black" android:layout_weight="1"
android:layout_marginLeft="1dp" android:layout_marginRight="1dp"
android:gravity="center_horizontal" android:layout_width="fill_parent" />
</LinearLayout>
Now everything is in place to create a custom class from BaseAdapter to display your information (and make your layout work better):
class CustomAdapter extends BaseAdapter {
private List<BatteryInfo> info;
private LayoutInflater inflater;
public CustomAdapter(Context context, List<BatteryInfo> x) {
this.info = x;
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return info.size();
}
public Object getItem(int position) {
return info.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View v;
v = inflater.inflate(R.layout.row, parent, false);
BatteryInfo b = (BatteryInfo) getItem(position);
((TextView) v.findViewById(R.id.maintableLeft)).setText(b
.getDurationTimeInString());
((TextView) v.findViewById(R.id.maintableRight)).setText(b
.getLevel());
return v;
}
}
Modify your onCreate method to inflate the header, add it, and then bind your data to your ListView using the new CustomAdapter (I've created a fake BatteryInfo class for this example, you'll need to modify things slightly to get this working):
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ListView lv = (ListView) this.findViewById(R.id.listView);
final Context context = this;
Button refresh = (Button) this.findViewById(R.id.button_Refresh);
refresh.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
List<BatteryInfo> x = new ArrayList<BatteryInfo>();
x.add(new BatteryInfo());
x.add(new BatteryInfo());
x.add(new BatteryInfo());
x.add(new BatteryInfo());
lv.setAdapter(new CustomAdapter(context, x));
}
});
}
