NOTICE : I am using from appcompat_v7 .

When you use ListFragment or ListActivity then ListView id in xml must be :
android:id="#id/android:list
Change your ListView id in xml :
<ListView
android:id="#id/android:list"
Instead of
<ListView
android:id="#+id/lstview_Setting_fragment"
Note : Try to set List Adapter in onCreateView() instead of onCreate() in Fragment.

android showing MapView in a list

I tried to load a mapView in the listView for each item using baseAdaptor everything seems to be fine but maps(mapviews) are loading this way(the picture below is a single item of the list):
adapter class:
public class InfoAdapter extends BaseAdapter {
protected MapView mMapView;
GoogleMap googleMap;
Activity activity;
Bundle bundle;
Context context;
LayoutInflater layoutInflater;
ArrayList<Info> infos;
public TripsAdapter(Activity activity, Context context, ArrayList<Info> infos, Bundle bundle) {
this.context = context;
this.activity = activity;
this.layoutInflater = LayoutInflater.from(activity);
this.infos = infos;
this.bundle = bundle;
}
#Override
public int getCount() {
return infos.size();
}
#Override
public Object getItem(int i) {
return infos.get(i);
}
#Override
public long getItemId(int i) {
return i;
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
if (view == null) {
view = layoutInflater.inflate(R.layout.list_infos_item, viewGroup, false);
view.findViewById(R.id.btnShare).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//share it
}
});
}
mMapView = (MapView) view.findViewById(R.id.fragment_embedded_map_view_mapview);
mMapView.onCreate(bundle);
return view;
}
}
the list_infos_item.xml is :

what is happening?how can I fix the problem?

Adding a Horizontal Scroll View to a ListView

I currently have an adapter that takes two images and a text view to add to a listView. I want to change this so that I can add a horizontalScrollView inside each list item that contains the images. Would there be any way to do this?
This my current working adapter as described above with two imageView's and a textView
public class MyAdapter extends BaseAdapter {
private Context mContext;
private List<Bean> mList;
private PopupWindow popUpWindow;
private LayoutInflater inflater;
public MyAdapter(Context context,List<Bean> list){
mContext=context;
mList=list;
}
#Override
public int getCount() {
return mList.size();
}
#Override
public Object getItem(int position) {
return mList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
//use convertView recycle
if(convertView==null){
holder=new ViewHolder();
convertView = LayoutInflater.from(mContext).inflate(R.layout.content_orders, parent, false);
holder.textView= (TextView) convertView.findViewById(R.id.textView2);
holder.imageView= (ImageView) convertView.findViewById(R.id.imageView2);
holder.imageView2 = (ImageView) convertView.findViewById(R.id.imageView3);
holder.information= (Button) convertView.findViewById(R.id.button5);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
//set text and url
final View finalConvertView = convertView;
holder.information.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ViewGroup container = (ViewGroup) inflater.inflate(R.layout.information_popup, null);
popUpWindow = new PopupWindow(container, 800,400,true);
popUpWindow.showAtLocation(finalConvertView.findViewById(R.id.orders), Gravity.CENTER, 0,0);
container.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View view, MotionEvent motionEvent) {
popUpWindow.dismiss();
return true;
}
});
}
});
holder.textView.setText(mList.get(position).getText());
Picasso.with(mContext).load(mList.get(position).getUrl()).resize(450,450).into(holder.imageView);
Picasso.with(mContext).load(mList.get(position).getUrl2()).resize(450,450).into(holder.imageView2);
return convertView;
}
class ViewHolder{
TextView textView;
ImageView imageView;
ImageView imageView2;
Button information;
}
}

I ended up figuring it out. In case anyone else wants to do this, this is the code I used. I just added a horizontalScrollView and I added a linearLayout with a horizontal direction inside the horizontalScrollView and then I added the images inside that linearLayout. This was my code.

Not exactly what you asked, but i think this question can help you.
HorizontalScrollView inside ListView: minor vertical scroll stops horizontal scroll

Android - update ListView in onCreate does not work

I have the following code:
public class MainActivity extends Activity {
private ListView list;
private static final String path = Environment.getExternalStorageDirectory().getPath() + File.separator + "BOE";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
list = (ListView) findViewById(R.id.listView1);
String books[] = {"Mercedes", "Skoda", "Volkswagen", "Audi", "Citroen", "plik"};
BookArrayAdapter bma = new BookArrayAdapter(this, books);
bma.setNotifyOnChange(true);
list.setAdapter(bma);
if (!new File(path).exists()) {
new File(path).mkdirs();
}
for (int i=0; i<books.length; i++) {
View v = list.getAdapter().getView(i, null, null);
String name = ((TextView)v.findViewById(R.id.row_text)).getText() + "";
for (File f:new File(path).listFiles()) {
if (f.isFile()) {
Button b = (Button) v.findViewById(R.id.row_button);
if (name.equals(f.getName().substring(0, f.getName().length()-4))) {
b.setText("Open");
} else {
b.setText("Download");
}
bma.notifyDataSetInvalidated();
bma.notifyDataSetChanged();
Log.d("AC", b.getText().toString());
}
}
}
}
public class BookArrayAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;
public BookArrayAdapter(Context context, String[] values) {
super(context, R.layout.row, values);
this.context = context;
this.values = values;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View rowView = inflater.inflate(R.layout.row, parent, false);
final TextView textView = (TextView) rowView.findViewById(R.id.row_text);
textView.setText(values[position]);
rowView.findViewById(R.id.row_button).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (((Button)v).getText().toString().equals("Open")) {
//open
} else {
//Download
}
}
});
return rowView;
}
}
}

how to update it? What is wrong?
EDIT:
I moved editing single row to getView(...) overrided method on my adapter class. I don't really know why my first idea was wrong, but now it works.

listView.setAdapter() is crashing my program

listView.setAdapter() is crashing my program. Anyone have any idea why the crash might be happening?

Because listView is not initialized.
Call getSavedVideo() method after initializing listView :
listView = (ListView)rootview.findViewById(R.id.savedVideoListView);
getSavedVideo();

ListView in nested fragment showing empty list item, (only textviews not images)

After googling alot i never found any helpful answer, so i'm posting my issue here. My problem is as follows :
I've a nested fragment (MainActivity calls SettingsFragment and that fragment calls another fragment named as ContactFragment) that uses a listview in it. I'm setting data in adapter but and call adapter.notifyDataSetChanged(); it adds an item with in ListView but show only images not TextViews. I debugged my code line by line each variable has its values but list items are not displaying it. Below is my Code.
ContactsFragment extends Fragment {
public static List<ContactItem> contactList;
private ContactsItemAdapter adapter;
private ListView lvContacts;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_contacts, container, false);
return rootView;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
lvContacts = (ListView) getView().findViewById(R.id.lvContacts);
contactList = new ArrayList<ContactItem>();
contactList.add(new ContactItem(R.drawable.ic_action_overflow, "OverFlow", "Testing", SOS.CONTACT_TYPE_SMS));
adapter = new ContactsItemAdapter(getActivity(), R.layout.contact_item, contactList);
lvContacts.setAdapter(adapter);
}
Following is a Click Event for adding an item to the list
private void btnAddOnClick(int type){
contactList.add(new ContactItem(R.drawable.ic_action_call, "ABC", "123", "SMS"));
adapter.notifyDataSetChanged();
}
}
Following is fragment_contacts.xml
<?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="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical" >
<ListView
android:id="#+id/lvContacts"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp" >
</ListView>
</LinearLayout>
By Calling btnAddOnClick adds item in listview but empty like this
here you can see it shows call icon but not showing text views values. Please tell me what i'm doing wrong.
Here is adapter
public class ContactsItemAdapter extends ArrayAdapter<ContactItem> {
private LayoutInflater mInflater;
public ContactsItemAdapter(Context context, int resource,
List<ContactItem> contactList) {
super(context, resource, contactList);
mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
TextView tvName;
TextView tvValue;
ImageView ivIcon;
ContactItem rowData = ContactsFragment.contactList.get(position);
if (null == convertView) {
convertView = mInflater.inflate(R.layout.contact_item, null);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
}
holder = (ViewHolder) convertView.getTag();
tvName = holder.getName();
tvName.setText(rowData.getName());
tvValue = holder.getValue();
tvValue.setText(rowData.getValue());
ivIcon = holder.getIcon();
ivIcon.setImageResource(rowData.getIcon());
return convertView;
}
public class ViewHolder {
private View mRow;
private TextView tvName = null;
private TextView tvValue = null;
private ImageView ivIcon = null;
public ViewHolder(View row) {
mRow = row;
}
public TextView getName() {
if (null == tvName) {
tvName = (TextView) mRow.findViewById(R.id.tvName);
}
return tvName;
}
public TextView getValue() {
if (null == tvValue) {
tvValue = (TextView) mRow.findViewById(R.id.tvValue);
}
return tvValue;
}
public ImageView getIcon() {
if (null == ivIcon) {
ivIcon = (ImageView) mRow.findViewById(R.id.icon);
}
return ivIcon;
}
}
}
ContactItem Class
public class ContactItem {
private int icon;
private String name;
private String value;
private String contactType;
public ContactItem() {
icon = R.drawable.ic_action_call;
name = "";
value = "";
contactType = "";
}
public ContactItem(int icon, String nameString, String valueString,
String type) {
this.icon = icon;
this.name = nameString;
this.value = valueString;
this.contactType = type;
}
public int getIcon() {
return icon;
}
public void setIcon(int icon) {
this.icon = icon;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
public String getContactType() {
return contactType;
}
public void setContactType(String contactType) {
this.contactType = contactType;
}
}

Your code should work, I think the problem is your contact_item.xml layout. Somehow your design is hiding the text. Use a simpler layout design to see if it shows the text, try getting rid of the LinearLayout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="55dp"

android:gravity="center_vertical" >
<ImageView
android:id="#+id/icon"
android:layout_width="25dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp"
android:contentDescription="#string/desc_list_item_icon" />
<View
android:id="#+id/divider"
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_alignParentBottom="true"
android:background="#android:color/darker_gray" />
<ImageView
