try this, In your combined.xml add layout width and height.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

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();
I managed to update the header View of adapters. listview, headerView (from listview), gridview within a single screen. the problem is due to listview and headerView display the same item, I want to hide the list view so as not to appear. how can i do that?
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View rootView = inflater.inflate(R.layout.fragment_home, container, false);
final Context gridContext = rootView.getContext();
gridView = (GridViewWithHeaderAndFooter) rootView.findViewById(R.id.grid);
this.inflaterGeneral = inflater;
headerView = inflaterGeneral.inflate(R.layout.cell_fragment_home_header_list, null);
listViewHeader = (ListView) headerView.findViewById(R.id.listViewHeader);
rootView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
return rootView;
}

Try to use [HeaderGridView][1], it subclass of GridView. I hope it helps.
I have an List Item with ImageView's, TextView's. Issue is List Item as whole is not clickable, it's only when I click on any of the ImageView it's clickable. I have set android:descendantFocusability="blocksDescendants" for root and below for each child

Still only ImageViews are clickable. Below is my list item xml

I am not sure where I am going wrong but struggling for last 6 hours.
Custom Adapter Code(Partial Coe):
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.list_listitem, parent,false);
holder.locName = (TextView) convertView
.findViewById(R.id.listitem_name);
holder.locDistance = (TextView) convertView
.findViewById(R.id.listitem_text2);
holder.locRating = (ImageView) convertView
.findViewById(R.id.listitem_img3);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
convertView.setOnClickListener(this);
holder.locName.setText(data.get(position).getLocationName());
return convertView;
Please advise.
Solution
Finally I was able to do this by using Relative Layout instead of Linear Layout in my list item layout.
Add the click listener when you inflate the view only. Try this:
convertView = inflater.inflate(R.layout.list_listitem, null);
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
convertView.setTag(holder);
Try using this on your Activity class:
listView.setItemsCanFocus(true);
or
listView.setItemsCanFocus(false);
which is useful for you.
I know its late but may be someone finds it helpful. In order to make the whole item as clickable instead of different items in a row use this
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
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"
android:orientation="vertical"

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

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:id="#+id/event_list_element_icon"
android:layout_width="26dip"

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"
I have a ListView where every row view is inflated from this xml layout (by activity layout inflater):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:baselineAligned="false"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/topic_list_item_selector"
android:orientation="horizontal"
android:paddingLeft="#dimen/list_item_padding_horizontal_big"
android:paddingBottom="#dimen/list_item_padding_vertical_big"
android:paddingTop="#dimen/list_item_padding_vertical_big" >
<LinearLayout
android:id="#+id/topics_list_edit_row_label_color"
android:layout_width="#dimen/label_rect_edge_size"
android:layout_height="#dimen/label_rect_edge_size"
android:orientation="vertical" >
<TextView
android:id="#+id/topics_list_edit_row_label_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textColor="#ffffff"
android:textSize="#dimen/label_text_size" />
</LinearLayout>
<LinearLayout

When I return this view in my Adapter via getView(), everything works normally.
But when I change some text in TextView via setText() in getView(), my app consumes about 1mb more with every screen rotation:
public class TopicListAdapter extends BaseAdapter{
...
public View getView(int position, View convertView, ViewGroup parent) {
View rowView;
if (convertView == null)
{
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = inflater.inflate(R.layout.topics_list_edit_row, parent, false);
...
Typeface myTypeface = Typeface.createFromAsset(context.getAssets(), "Roboto-Thin.ttf"); //Added
TextView labelT = (TextView) rowView.findViewById(R.id.topics_list_edit_row_label_text);
labelT.setTypeface(myTypeface); //Added
labelT.setText("A"); //!!!! when I delete this line everything works normally !!!!
...
}
...
}
}
I think maybe my activity context remains alive after every screen rotation but if this is the case then how does it happen and how do I avoid it?
