Have you tried,
removing l1.setItemsCanFocus(true); and simply using:
...
else {
showSplashScreen();
setContentView(R.layout.main);
final ListView l1 = (ListView) findViewById(android.R.id.list);
l1.setAdapter(new EfficientAdapter(this));
l1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long arg) {
Object listItem = l1.getItemAtPosition(position);
Log.v("MyApp", "get onItem Click position= " + position);
Toast.makeText(getApplicationContext(), listItem.toString(),Toast.LENGTH_SHORT).show();
Toast.makeText(getApplicationContext(), "Valid", Toast.LENGTH_SHORT).show();
}
});
}
and removing
convertView.setClickable(true);
convertView.setFocusableInTouchMode(true);
convertView.setFocusable(true);
and using it like:
public static class EfficientAdapter extends BaseAdapter {
private LayoutInflater mInflater;
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return country.length;
}
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.listview, null);
holder = new ViewHolder();
holder.text = (TextView) convertView.findViewById(R.id.TextView01);
holder.text2 = (TextView) convertView.findViewById(R.id.TextView02);
holder.text3 = (TextView) convertView.findViewById(R.id.TextView03);
holder.text4 = (TextView) convertView.findViewById(R.id.TextView04);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
}
holder.text.setText(curr[position]);
holder.text2.setText(country[position]);
holder.text3.setText(country[position]);
holder.text4.setText(country[position]);
return convertView;
}
static class ViewHolder {
TextView text4;
TextView text;
TextView text2;
TextView text3;
}
}
??
If you tried this,and it doesn't work,please show us your logcat for errors if you are getting any.

and adapter
public class Rules_d_adapter extends BaseAdapter{
private Context context;
List<String> question =new ArrayList<String>();
List<String> answer =new ArrayList<String>();
public Rules_d_adapter(Context con,List<String> Lines,List<String> Lines2)
{question=Lines;
answer=Lines2;
context = con;
}
#Override

return question.size();
}
#Override
public Object getItem(int i) {
return question.size();
}
#Override
public long getItemId(int i) {
return question.size();
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
LayoutInflater inflater = (LayoutInflater)
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.rules_d_adapter, viewGroup, false);
Custom_Roboto_Light tv2 =
(Custom_Roboto_Light)view.findViewById(R.id.tv2) ;
Custom_Roboto_Regular tv = (Custom_Roboto_Regular)
view.findViewById(R.id.tv1) ;
tv.setText(question.get(i));
tv2.setText(answer.get(i));
return view;
}
}

if you still happy with ListView then you can take idea from below
code
here i am using Cursor but you can use ArrayList in place of Cursor
public class Custom_Adapter_Products extends BaseAdapter {
Context context;
Cursor mCursor;
static int[] intArr;
DatabaseAdapter db;
public ImageLoader imageLoader;
public Custom_Adapter_Products(Context context, Cursor mCursor){
this.context = context;
this.mCursor = mCursor;
this.intArr = new int[this.mCursor.getCount()];
imageLoader=new ImageLoader(context);
}
#Override
public int getCount() {
return mCursor.getCount();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
try{
ViewHolder holder;
this.mCursor.moveToPosition(position);
LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
{
convertView = vi.inflate(R.layout.lv_row_for_products, null);
holder = createViewHolder(convertView);
convertView.setTag(holder);
holder.btnMinus.setTag(holder);
holder.btnAdd.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.btnMinus.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try{
ViewHolder holder = (ViewHolder) v.getTag();
// Do whatever you want
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
});
}catch (Exception e){
// TODO: handle exception
e.printStackTrace();
}
return convertView;
}
private static class ViewHolder
{
public TextView tvProductName;
public TextView tvPrice;
public TextView tvMRP;
public TextView tvMOQ;
public TextView tvPercent;
public TextView tvQuantity;
public ImageView imgProduct;
public ProgressBar pBar;

I have wasted a lot of time finding the problem but i cannnot understand why it is not showing on the screen. please guide me.

Correct in your code as below:
#Override
public Object getItem(int arg0) {
return planArraylist.get(planArraylist.get(arg0-1)); }
#Override
public long getItemId(int arg0) {
return arg0; }

I think you write you getView method differently and use a holder class, as shown below:
#Override
public Object getItem(int arg0) {
return planArraylist.get(arg0);
}
#Override
public long getItemId(int arg0) {
return arg0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.single_lv_item, parent, false);
holder = new ViewHolder();
holder.tvdrCode = (TextView) convertView.findViewById(R.id.dcode);
holder.tvDrName = (TextView) convertView.findViewById(R.id.dname);
holder.tvTerr = (TextView) convertView.findViewById(R.id.tcode);
holder.tvAdr = (TextView) convertView.findViewById(R.id.a);
holder.tvClassDesc = (TextView) convertView.findViewById(R.id.cd);
holder.tvShift = (TextView) convertView.findViewById(R.id.tvshift);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
Planning p = planArraylist.get(position);
holder.tvdrCode.setText(p.getDrCode());
holder.tvDrName.setText(p.getDocName());
holder.tvTerr.setText(p.getTerrCode());
holder.tvAdr.setText(p.getAdr());
holder.tvClassDesc.setText(p.getClassDesc());
holder.tvShift.setText(p.getShift());
return convertView;
}
static class ViewHolder {
TextView tvdrCode;
TextView tvDrName;
TextView tvTerr;
TextView tvAdr;
TextView tvClassDesc;
TextView tvShift;
}
Also, your list view xml file uses a Linear layout but you have properties that can only be found in a Relative layout such as android:layout_alignParentTop="true". Could you fix that as well?

Adding radio button to listview

I would like to add a radio button to my existing listview so that only one radio button needs to be selected at a time.
ItemDetails:
public class ItemDetails {
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getItemDescription() {
return itemDescription;
}
public void setItemDescription(String itemDescription) {
this.itemDescription = itemDescription;
}
public String getPrice() {
return price;
}
public void setPrice(String price) {
this.price = price;
}
public int getImageNumber() {
return imageNumber;
}
public void setImageNumber(int imageNumber) {
this.imageNumber = imageNumber;
}
private String name ;
private String itemDescription;
private String price;
private int imageNumber;
}
Adapter:

holder.itemImage = (ImageView) convertView.findViewById(R.id.photo);
convertView.setTag(holder);
} else {

}
holder.txt_itemName.setText(itemDetailsrrayList.get(position).getName());

</LinearLayout>
I have seen many SO anwsers but none of them got working in my case saying to add
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
Can anyone say me how to acheive this ?

For complex ListView item, you should do it by yourself. Just add boolean isSelected in your ItemDetails and then checkBox.setChecked(item.isSelected); in your getView() in ItemListBaseAdapter. Now when an item is clicked in ListView just change your the data in itemDetailsrrayList and call notifyDataSetChanged().

I have made my getView() method.Just make radio button instead of simple button.I Hope this helps.
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View productListView = null;
productListView = convertView;
LayoutInflater inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (productListView == null)
productListView = inflater.inflate(R.layout.menu_productlist_list,
parent, false);
productListTitle = (TextView) productListView
.findViewById(R.id.productListTitle);
String title = menuProductListCollection.get(position).getPD_TITLE();
productListTitle.setText(title);
productListCategoryButton = (ImageButton) productListView
.findViewById(R.id.productListCategoryButton);
// Perform Button action on click of each row's button
productListCategoryButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
//do your stuff here
}
});
// Perform action on click of each row
productListView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
//do your stuff here
}
});
return productListView;
}

I think you should try both of this,
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
And in xml file you need to add,
<ListView
...
android:choiceMode="singleChoice"
... />
Also add this in your radio-button's xml,
<RadioButton
...
android:clickable="false"
android:focusable="false"
... />
Make HashMap m and initialize it
for (HashMap<String, Object> m :list_data) //make data of this view should not be null (hide )
m.put("checked", false);
Now, setViewBinder to adapter
adapter.setViewBinder(new SimpleAdapter.ViewBinder()
{
public boolean setViewValue(View view, Object data, String textRepresentation)
{
if (data == null) //if 2nd line text is null, its textview should be hidden
{
view.setVisibility(View.GONE);
return true;
}
view.setVisibility(View.VISIBLE);
return false;
}
});
It will work like charm.

CheckBox in custom ListView on Android

I got a custom ListView, and I put three TextView in the List using a custom List Adapter! How I can to add a CheckBox with each List Item and make each CheckBox checked on list item click?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textColor="#7a4b9d"
android:textSize="15sp"
android:textStyle="bold" />
<TextView
android:id="#+id/calorie"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="sdf"
android:textColor="#ffffff" />
<TextView
android:id="#+id/price"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="sdf"
android:textColor="#ffffff" />
<CheckBox
android:id="#+id/chkBox1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="CheckBox" />
</LinearLayout>
MainActivity
public class Main_Activity extends Fragment implements OnClickListener {
private ListView lv;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
ViewGroup root = (ViewGroup) inflater.inflate(R.layout.main_activity, null);
ArrayList<SearchResults> searchResults = GetSearchResults();
final ListView lv = (ListView) root.findViewById(R.id.list_two);
lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
lv.setTextFilterEnabled(true);
lv.setAdapter(new MyCustomBaseAdapter(getActivity(), searchResults));
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> a, View v, int position,
long id) {
boolean result = searchResults.get(position).isSolved();
if (result) {
searchResults.get(position).setSolved(false);
} else {
searchResults.get(position).setSolved(true);
}
Toast.makeText(getActivity(),"You have chosen: " + " " +
fullObject.getPhone(), Toast.LENGTH_SHORT).show();
}
});
return root;
}
private ArrayList<SearchResults> GetSearchResults() {
ArrayList<SearchResults> results = new ArrayList<SearchResults>();
SearchResults sr = new SearchResults();
sr.setName("Apple");
sr.setCalorie("35");
sr.setPrice("5");
results.add(sr);
return results;
}
}
Custom Base Adapter
public class MyCustomBaseAdapter extends BaseAdapter {
private static ArrayList<SearchResults> searchArrayList;
private LayoutInflater mInflater;
public MyCustomBaseAdapter(Context context, ArrayList<SearchResults> results) {
searchArrayList = results;
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return searchArrayList.size();
}
public Object getItem(int position) {
return searchArrayList.get(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.custom_row_view, null);
holder = new ViewHolder();
holder.txtName = (TextView) convertView.findViewById(R.id.name);
holder.txtCalorie = (TextView) convertView
.findViewById(R.id.calorie);
holder.txtPrice = (TextView) convertView.findViewById(R.id.price);
holder.chkBox1 = (CheckBox)convertView.findViewById(R.id.chkBox1);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.txtName.setText(searchArrayList.get(position).getName());
holder.txtCalorie.setText(searchArrayList.get(position)
.getCalorie());
holder.txtPrice.setText(searchArrayList.get(position).getPrice());
holder.chkBox1.setChecked(searchArrayList.get(position).isSolved());
return convertView;
}
static class ViewHolder {
CheckBox chkBox1;
TextView txtName;
TextView txtCalorie;
TextView txtPrice;
}
Search Results
public boolean isSolved() {
// TODO Auto-generated method stub
return b;
}
public void setSolved(boolean b) {
// TODO Auto-generated method stub
this.b = b;
}

You will have to define your CheckBox view in custom_row_view.xml file first,
<CheckBox android:id="#+id/chkBox1"
android:layout_width=...
android:layout_height=... />
Then, you wll have to call this reference in your MyCustomBaseAdapter class or in the holder in your case, like
CheckBox chkBox1;
then,
holder.chkBox1 = = (CheckBox)convertView.findViewById(R.id.chkBox1);
You can define a boolean value in your SearchResults class which can take care of chkBox check and use
holder.chkBox1.setChecked(searchArrayList.get(position).isSolved());
Something on these lines and you will be good to go :)
EDIT: Remember to change the value of boolean in searchResult instance on itemClick.
boolean result = searchResults.get(position).isSolved();
if (result) {
searchResults.get(position).setSolved(false);
} else {
searchResults.get(position).setSolved(true);
}
lv.getAdapter().notifyDataSetChanged();
