}
return view;
}
}
The problem is: Only the #+id/address TextView shows the text successfully, other things are not shown. But I don't know why this happened.
How can I solve this problem ? Can someone help me ?
Thanks.
Use ScrollView intead of outer(parent) ListView.
And use LisView for the inner ListView.
It gives you the scrolling feature.
1/ layout_below only works in RelativeLayout, you are using a LinearLayout with horizontal orientation so all the elements will be rendered side by side, and all elements have the layout_width:"match_parent" so only the first element will be shown.
2/ when you use a ListView in another scrollView the renderer can't calculate the height of the second one

im just trying to create a listview using a simple adapter. the setadapter is not working. this is my code. my setcontentview is before this block of code and this is in oncreate.
ArrayList<HashMap<String,String>> arraylist = new ArrayList<HashMap<String,String>>();
HashMap<String,String> map = new HashMap<String,String>();
map.put("CType", "Alarm");
map.put("RType", "Once");
map.put("hour", "1");
map.put("minute", "1");
map.put("second", "30");
arraylist.add(map);
String[] stringarray= new String[] {"CType", "RType", "hour","minute","second"};
int[] intarray = new int[] {R.id.clocktextviewalarmtimer,R.id.clocktextviewrepeatonce,
R.id.clocktextviewhours,R.id.clocktextviewminutes,R.id.clocktextviewseconds};
ListView clocklistview = (ListView)findViewById(R.id.clocklistview);
SimpleAdapter adapter = new SimpleAdapter(this,arraylist,R.layout.list_clock,stringarray,intarray);
clocklistview.setAdapter(adapter);
this is the xml that contains my listview

Here's an example of a custom adapter. Try this ...
public class ClockListAdapter extends BaseAdapter {
ArrayList<HashMap<String, String>> _arrayList;
ClockListAdapter(Context context, ArrayList<HashMap<String, String>> arrayList) {
this._arrayList = arrayList;
}
#Override
public int getCount() {
return (_arrayList != null) ? _arrayList.size() : 0;
}
#Override
public Object getItem(int position) {
return (_arrayList != null) ? _arrayList.get(position) : null;
}
#Override
public long getItemId(int position) {
return (_arrayList != null) ? _arrayList.indexOf(_arrayList.get(position)) : 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
// REPLACE WITH YOUR LAYOUT FILE vvvvvvvvvv
convertView = layoutInflater.inflate(android.R.layout.simple_list_item_1, null);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder._textView.setText("set some text here");
return convertView;
}
public class ViewHolder {
// ADD YOUR VIEW(S) vvvvvvvvv
TextView _textView;
ViewHolder(View v) {
// REPLACE WITH YOUR TEXT vvvvvvvvv
_textView = (TextView) v.findViewById(R.id.textView1);
}
}
}
I've searched but not found any examples for what I want to do. I'm sure its trivial but I'm stumped. I have a custom listview adapter and a defined relative layout. The entire layout is being called for each item, I want my buttons to only appear once on top. Any advice would be greatly appreciated.
This is how it looks now:

You need to define the header as a separate layout (separate xml file) then instantiate it and add it to the listview as a header -- then this layout will show as the first item in the list.
See this question: Android ListView with complex header
I have to apply pagination concept on ListView my list view contains data parsed from web service. below is code given that how I have displayed data in list view as below.

System.out.println("...serialized data.."+arl);

R.id.txtpetpolicyH, R.id.txtpetpolicyC }

lv1.setScrollbarFadingEnabled(false);
lv1.refreshDrawableState();
lv1.setAdapter(adapter);
} catch (Exception e) {

you just need to add a Footer View in the Listyou created. Then for the footer view (might be button/image/text) set a ClickListener for that and in Listener add the items into your list and again refresh the activity. I am adding a little tutorial that will help you in this.
I used the following Method for Pagination:
The List Class:
public class customListView extends Activity implements OnClickListener{
private static class EfficientAdapter extends BaseAdapter {
private LayoutInflater mInflater;

public EfficientAdapter(Context context) {
this.context = context;
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return add_Names.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.listcontent, null);
holder = new ViewHolder();
holder.text = (TextView) convertView
.findViewById(R.id.txt1);
holder.text2 = (TextView) convertView
.findViewById(R.id.txt2);
holder.text3 = (TextView) convertView
.findViewById(R.id.txt3);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.text.setText(add_Names.get(position).toString());
holder.text2.setText(location.get(position).toString());
holder.text3.setText(details.get(position).toString());
return convertView;
}
static class ViewHolder {
TextView text;
TextView text2;
TextView text3;
}
}//end of efficient Adapter Class
#Override

Here is my Listview Activity
public class LatestMatchesListActivity extends ListActivity {
...
private void createMatchList() {
/*
Log.i(MY_DEBUG_TAG, "Checking Match store size before passing it to custom adapter: "+mStore.size());
if(mStore.size() == 0){
Log.i(MY_DEBUG_TAG, "Got Empty match store, so checking connectivity..");
Match m = new Match();
if(isOnline()){
Log.i(MY_DEBUG_TAG, "Internet is accessible, so adding no matches object: ");
m.setId(-1);
} else{
Log.i(MY_DEBUG_TAG, "No Internet accessible, so adding mo caonnectivity match object: ");
m.setId(-2);
}
mStore.add(m);
} else {
Log.e(MY_DEBUG_TAG, "Match store is not empty ");
}
*/
//mStore.clear();
Log.i(MY_DEBUG_TAG, "Passing match list to custom adapter: "+mStore.toString());
this.mAdapter = new MatchAdapter(this, R.layout.list_matches, mStore);
this.setListAdapter(this.mAdapter);
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setBackgroundDrawable(null);
lv.setBackgroundResource(0);
}
and the custom ArrayAdapter
public class MatchAdapter extends ArrayAdapter<Match> {
private ArrayList<Match> items;
private final String MY_DEBUG_TAG = "MatchAdapter";
public MatchAdapter(Context context, int textViewResourceId, ArrayList<Match> items) {
super(context, textViewResourceId, items);
this.items = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.list_matches, null);
}
Match m = items.get(position);
if (m != null) {
TextView itemLabel = (TextView) v.findViewById(R.id.item_match_label);
ImageView imageFlagLeft = (ImageView) v.findViewById(R.id.flag_left);
ImageView imageFlagRight = (ImageView) v.findViewById(R.id.flag_right);
if(m.getId() == -1){
itemLabel.setText("No Live Matches.");
imageFlagLeft.setVisibility(View.INVISIBLE);
imageFlagRight.setVisibility(View.INVISIBLE);
} else if(m.getId() == -2){
itemLabel.setText("No Intenet connectivity.");
imageFlagLeft.setVisibility(View.INVISIBLE);
imageFlagRight.setVisibility(View.INVISIBLE);
} else {
itemLabel.setText(m.getTeam1() + " v/s " + m.getTeam2());
imageFlagLeft.setImageResource(getFlagResource(m.getTeam1()));
imageFlagRight.setImageResource(getFlagResource(m.getTeam2()));
}
}
return v;
}
private int getFlagResource(String teamName) {
Log.i(MY_DEBUG_TAG, "Getting the flag of " + teamName);
String flagString = "flag_" + teamName.replace(" ", "_").toLowerCase();
int resId = getContext().getResources().getIdentifier(flagString, "drawable", "com.itflux.DroidChirp");
if (resId != 0) {
return resId;
}
return R.drawable.flag_default;
}
}
You have your ListView fit the screen, and in LinearLayout your TextView is displayed under that ListView so it's not visible (it would be, if you'd use a ScrollView).
You need to use as the root element of your layout a RelativeLayout for instance, to have the TextView on top of the ListView.
Seems like the question is still unsolved. So here is how I solved it. I triggered a function which will basically refresh the list layout whenever the data changes as below:
ListView lv = getListView();
lv.requestLayout();
if(aa.arrayValue.size() > 0) {
lv.setVisibility(ListView.VISIBLE);
setListAdapter(new Adaptor(this, R.layout.main_list_item, aa.arrayValue));
}
else {
lv.setVisibility(ListView.INVISIBLE);
TextView tv = (TextView) findViewById(android.R.id.empty);
tv.requestLayout();
tv.setVisibility(TextView.VISIBLE);
}
Hope this helps you out!
Use #+id in empty and #id in list : android:id="#+id/android:empty"
Your problem is with the ListView height property. Set it to wrap_content.
