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"

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 am facing a really strange behaviour where I set an onClickListener on checkboxes and their labels, within a custom adapter.
The problem is when I check an answer on the first question, the same item on the 3rd question is checked too. The checkboxes seems to be synchronised, but i don't understand why.
Here is some screens to understand.
1rst question
3rd question
Here is the getView() from my adapter:
public View getView(final int position, View convertView, ViewGroup parent)
{
View vi = convertView;
if(convertView == null)
{
vi = inflater.inflate(R.layout.question_item, null);
}
Qcm qcm = qcms.get(position);
List<Proposition> propositions = qcm.getPropositionsList();
TextView numQuestion = (TextView)vi.findViewById(R.id.question_number_item);
TextView question = (TextView)vi.findViewById(R.id.question_text);
LinearLayout[] labels = new LinearLayout[5];
labels[0] = (LinearLayout)vi.findViewById(R.id.question_label1);
labels[1] = (LinearLayout)vi.findViewById(R.id.question_label2);
labels[2] = (LinearLayout)vi.findViewById(R.id.question_label3);
labels[3] = (LinearLayout)vi.findViewById(R.id.question_label4);
labels[4] = (LinearLayout)vi.findViewById(R.id.question_label5);
final CheckBox[] checkBoxes = new CheckBox[5];
checkBoxes[0] = (CheckBox)vi.findViewById(R.id.question_check1);
checkBoxes[1] = (CheckBox)vi.findViewById(R.id.question_check2);
checkBoxes[2] = (CheckBox)vi.findViewById(R.id.question_check3);
checkBoxes[3] = (CheckBox)vi.findViewById(R.id.question_check4);
checkBoxes[4] = (CheckBox)vi.findViewById(R.id.question_check5);
numQuestion.setText(String.valueOf(position+1));
question.setText(Html.fromHtml(qcm.getQuestion()));
for(int i=0; i<5; i++)
{
final int cpt = i;
checkBoxes[i].setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Checked[i] -> !Checked[i]
QcmListAdapter.this.checked[position][cpt] = !QcmListAdapter.this.checked[position][cpt];
APIHelper.log('d', "position="+position);
// TODO : Faire la methode PlaySerieFragment.saveSession();
//QcmListAdapter.this.activity.getFragmentManager().getFragment(QcmListAdapter.this.);
}
});
labels[i].setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
checkBoxes[cpt].performClick();
APIHelper.log('d', "onClick:cpt="+cpt);
}
});
Proposition p = propositions.get(i);
p.setFormattedView(this.activity, labels[i], (i + 1));
}
return vi;
}

I suspect this is because the view is getting re-used. Android re-uses views in a listview for performance, as the view is re-used when you click the same view displays the checked state.
You can either remove the if statement around convertView
if(convertView == null)
..
But this will be determental to performance if you have a lot of items.
Otherwise you should use the common viewHolder method:

Hope this helps.
I have a problem with my GridView when it receives incomplete row item number, it doesn't scroll anymore. My items are dynamic which are given by the server, I have 3 columns and if the number of GridView items are more than enough to enable scrolling and if the row item is 3, it works fine. For example (9 items):
But if the third row has only 1 or 2 item/s, it doesn't scroll anymore (7 or 8 items):
This has caused me headache more than excitement, my GridView in layout is:
<GridView
android:id="#+id/gridView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#color/white"
android:listSelector="#android:color/transparent"
android:numColumns="3"
android:stretchMode="columnWidth" >
</GridView>
In my activity nothing much, just declaration and setting its adapter. Did I miss anything? I tried adding verticalSpacing and padding separately but nothing's changed.
EDIT:
This is the setup in the whole layout:
Black is a RelativeLayout, FrameLayout and the last ImageView are aligned top and bottom respectively. Top TextView is below FrameLayout, bottom TextView is below top TextView. Now GridView is below bottom TextView and above ImageView, it should expand its height basing to the space left consumed between the first 3 elements and the bottom element. This is how it's setup in my layout.
I believe it's a layout problem more than in my code since I've done dozens of ListView and this has similar implementation.
EDIT2:
The layout:

Don't mind the ImageViews, I just took out their source. I needed to retain the setup from my actual layout. The code:
public class SixthActivity extends Activity {
private Integer[] gridViewItem = new Integer[] { 1, 2, 3, 4, 5, 6, 7, 8 };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sixth);
GridView gridView = (GridView) findViewById(R.id.grid_view);
CustomAdapter adapter = new CustomAdapter(this,
R.layout.item_module, gridViewItem);
gridView.setAdapter(adapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.sixth, menu);
return true;
}
}
The adapter:
public class CustomAdapter extends ArrayAdapter<Integer> {
private Context context;
private int resource;
private Integer[] moduleList;
public CustomAdapter(Context context, int resource,
Integer[] moduleList) {
super(context, resource, moduleList);
// TODO Auto-generated constructor stub
this.context = context;
this.resource = resource;
this.moduleList = moduleList;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View row = convertView;
ViewHolder holder = null;
if (row == null) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
row = inflater.inflate(resource, parent, false);
holder = new ViewHolder();
row.setTag(holder);
} else {
holder = (ViewHolder) row.getTag();
}
holder.tvModuleName = (TextView) row.findViewById(R.id.module_name);
holder.tvModuleImage = (ImageView) row.findViewById(R.id.module_image);
holder.tvModuleName.setText("SAMPLESAMPLE");
return row;
}
public class ViewHolder {
public ImageView tvModuleImage;
public TextView tvModuleName;
}
}
The item layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/item_module"
android:layout_width="wrap_content"

</LinearLayout>
Try to add numbers to gridViewItem to add items enough to trigger the scrolling just like in my screenshots, and try taking out 1 or 2 items at the bottom such that that row would be incomplete to replicate my problem. Thanks.
PLease help me with layout of the two list views placed vertically in the Linear Layout. Problem is that if list1 had more data than list2 is not visible and it not scrollable, using scollview is not solution.

If I use the scrollview then it is wrapping up the listview for only first row.
Please suggest something.

EDIT : CODE FOR THE TWO LISTVIEWS:
{
arrayofWebData.add(cn);
listAdapter = new SelectArralAdapter(getActivity(),
arrayofWebData);
List_events.setAdapter(listAdapter);
}
For the Second ListView it is as follows :
if ((year == event_year) && (event_month == month))
{
arrayofWebDataPress.add(cn);
listAdapter_press = new SelectArralAdapter_Press(getActivity(),arrayofWebDataPress);
List_events_press.setAdapter(listAdapter_press);
i++;
}
Array Adapter for the two ListViews :
class SelectArralAdapter_Press extends ArrayAdapter<PressDB> {
private LayoutInflater inflater;
public SelectArralAdapter_Press(Context context,
ArrayList<PressDB> arrayofWebDataPress) {
super(context, R.layout.speech_list_item, R.id.event_title,
arrayofWebDataPress);
inflater = LayoutInflater.from(context);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder_Press holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.speech_list_item, null);
holder = new ViewHolder_Press(convertView);
convertView.setTag(holder);
} else {
holder = (ViewHolder_Press) convertView.getTag();
}
holder.populateFrom(arrayofWebDataPress.get(position));
return (convertView);
}
}
class ViewHolder_Press{
public TextView event_name = null;
public TextView event_date = null;
public ViewHolder_Press(View row) {
event_name = (TextView) row.findViewById(R.id.event_title);
event_date = (TextView) row.findViewById(R.id.event_date_time);
}
void populateFrom(PressDB eventsMainDB) {
event_name.setText(eventsMainDB.press_name);
event_date.setText(eventsMainDB.press_date + " ");
}
}
For the second Adaper :
class SelectArralAdapter extends ArrayAdapter<SpeechDB> {
private LayoutInflater inflater;
public SelectArralAdapter(Context context,
ArrayList<SpeechDB> arrayofWebData) {
super(context, R.layout.speech_list_item, R.id.event_title,
arrayofWebData);
inflater = LayoutInflater.from(context);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.speech_list_item, null);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.populateFrom(arrayofWebData.get(position));
return (convertView);
}
}
class ViewHolder {
public TextView event_name = null;
public TextView event_date = null;
public ViewHolder(View row) {
event_name = (TextView) row.findViewById(R.id.event_title);
event_date = (TextView) row.findViewById(R.id.event_date_time);
}
void populateFrom(SpeechDB eventsMainDB) {
event_name.setText(eventsMainDB.speech_name);
event_date.setText(eventsMainDB.speech_date + " ");
}
}
Try this.
If you want to go with the xml design then you have to give the fix size, either by using the weight (this is most preferable) or by giving the fix size in dp.

i am getting this screen at design time.
i have used like:
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFF">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center">
// first linearlayout which is holding one textview and a listview
<LinearLayout
">
<TextView
/>
<ListView
android:id="#+id/failed_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="5dp"/>
</LinearLayout>
// second linearlayout which is holding one textview and a listview
<LinearLayout
">
<TextView
/>
<ListView
android:id="#+id/failed_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="5dp"/>
</LinearLayout>
// third linearlayout which is holding one textview and a listview
<LinearLayout
">
<TextView
/>
<ListView
android:id="#+id/failed_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="5dp"/>
</LinearLayout>
// and finally i have added a button in the parent linearlayout
<Button
/>
</LinearLayout>
</ScrollView>
you can try this.
Try out as below :
Here is the solution to more than one ListView within the same layout file. You can set the layout files as the below layout by providing the equal weights to each layout inside the LinearLayout.
<LinearLayout android:layout_weight="1"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<ListView android:id="#+id/list1"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
</ListView>
</LinearLayout>
<LinearLayout android:layout_weight="1"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<ListView android:id="#+id/list2"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
</ListView>
</LinearLayout>
Java Code
public class MainActivity extends Activity {
private ListView lv1 = null;
private ListView lv2 = null;
private String s1[] = {"a", "b", "c", "d", "e", "f"};
private String s2[] = {"r", "s", "t", "u", "v", "w", "x"};
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
lv1 = (ListView) findViewById (R.id.list1);
lv2 = (ListView) findViewById (R.id.list2);
lv1.setAdapter(new ArrayAdapter<String> (this, android.R.layout.simple_list_item_1, s1));
lv2.setAdapter(new ArrayAdapter<String> (this, android.R.layout.simple_list_item_1, s2));
}
}
For more details you can refer the Link which have given the solution for same.
I hope it will help you.
Thanks.
You can take something like this.
<LinearLayout>
<ScrollView>
<LinearLayout>
{Your All code of controls}
</LinearLayout>
</ScrollView>
</LinearLayout>
OR uo can take <ScrollView> as parent tag..
You can do something like this. as per my Knowledge...
I solved the issue by using section headers and combining the two listviews into one listview and categorizing them by help of Section headers.
This is my main.xml:`
<RelativeLayout

android:layout_alignParentTop="true">
<TableRow>
<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="30dip" />
<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="70dip" />
</TableRow>
</TableLayout>
<ScrollView
android:id="#+id/table_scroll"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginRight="2dp"
android:layout_marginLeft="2dp"
android:layout_below="#+id/header"
android:layout_above="#+id/buttonTable">
<TableLayout
android:id="#+id/maintable"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black">
<TableRow
android:id="#+id/maintableRow">
<TextView
android:id="#+id/maintableLeft"
android:layout_height="0dp"
android:layout_weight="1"
android:layout_marginRight="1dp"
android:layout_marginLeft="1dp"

android:layout_width="30dip" />
<TextView
android:id="#+id/maintableRight"
android:layout_height="0dp"
android:layout_weight="1"
android:layout_marginLeft="1dp"

android:layout_width="fill_parent"
android:text="Refresh"
android:gravity="center"
android:layout_weight="1" />
</TableRow>
</TableLayout>

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));
}
});
}
