I've read some thread that has the same issue like mine. They use adapter to fix the issue but still in my case this error still occur. Any help is much appreciated.

Do Your Selection after you set Your Adapter to the Listview
private void loadIntoListView(String json) throws JSONException {
JSONArray jsonArray = new JSONArray(json);
//String[] question = new String[jsonArray.length()];
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject obj = jsonArray.getJSONObject(i);
String id = obj.getString(TAG_QID);
String content = obj.getString(TAG_TITLE);
String image = obj.getString(TAG_IMAGE);
String a = obj.getString(TAG_A);
String b = obj.getString(TAG_B);
String c = obj.getString(TAG_C);
String d = obj.getString(TAG_D);
String key = obj.getString(TAG_KEY);
String timer = obj.getString(TAG_TIMER);
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_QID,id);
map.put(TAG_TITLE,content);
map.put(TAG_IMAGE,image);
map.put(TAG_A,a);
map.put(TAG_B,b);
map.put(TAG_C,c);
map.put(TAG_D,d);
map.put(TAG_KEY,key);
map.put(TAG_TIMER,timer);
myqid.add(id);
questions.add(map);
}
// ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, question);
SimpleAdapter adapter = new SimpleAdapter(
QandAPractice.this, questions,
R.layout.quizlayout, new String[]{TAG_QID,
TAG_TITLE, TAG_IMAGE,TAG_A,TAG_B,TAG_C,TAG_D,TAG_KEY,TAG_TIMER},
new int[]{R.id.quiz_id, R.id.quiz_content, R.id.quiz_image,R.id.quiz_A,R.id.quiz_B,
R.id.quiz_C,R.id.quiz_D,R.id.quiz_key,R.id.quiz_timer});
/* AtomicReference<ListAdapter> la =
new AtomicReference<>(new ListAdapter(getApplicationContext(), questions));*/
listView.setAdapter(adapter);
listView.setSelection(0);
listView.getSelectedView().setSelected(true);
}

I think I got the main issue you have faced. You try to select an item before populating the list view. You need to set this after adapter added on the listview.
Add this lines after adding the adapter.
listView.setAdapter(adapter);
listView.setSelection(0);
listView.getSelectedView().setSelected(true);
or use
listView.setAdapter(adapter);
listView.setItemChecked(0, true)
This will show a toast message for first opening. This should be added after the adapter set.
Iterator myVeryOwnIterator = questions.get(0).keySet().iterator();
while(myVeryOwnIterator.hasNext()) {
String key=(String)myVeryOwnIterator.next();
String value=(String)meMap.get(key);
Toast.makeText(ctx, "Key: "+key+" Value: "+value, Toast.LENGTH_LONG).show();
}

Inserting tabbed views for already created activities

I am new to android and stackoverflow so forgive if it sounds or reads silly. I have a listview of suppose 10 job details. The list consists of only the names of the jobs. When I tap on any name, I want to open two tabbed views. The first tab would contain further details of the job and the second tab would contain a data entry page which will take input from the user for storage. All the job details (names and further details) are parsed from a json string fetched from the web.
Now, I have created the listview and the details page (containing further details of a single job). But I can't implement the tabbed view on the details page, i.e., I can't make a normal activity tabbed. Please help.
Note: The job list page gets all the details too, but in the XML the visibility of all the details except the job name is kept at "gone".

Android while using cardview image is loading very lazy

I am loading pictures (below ~3MB in size) into Cardview from a database and it was infalte in Listviewstview.
The loading and browsing of these pictures is way too slow.
Is there any method to downscale these pictures to speed up & sometimes dispalyind [Duplicate] images on other card view?

Try scale your bitmap to lower its actual resolution, I've used the following codes to reduce bitmap's size.
int nh = (int) (bitmap.getHeight() * (512.0 / bitmap.getWidth()));
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, 512, nh, true);
For you case, add the following codes into your adapter class AsyncTask's doInBackground method
try {
bitmap = BitmapFactory.decodeStream((InputStream) new URL(args[0]).getContent());
int nh = (int) (bitmap.getHeight() * (512.0 / bitmap.getWidth()));
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, 512, nh, true);
} catch (Exception e) {
e.printStackTrace();
}
return scaled;
Return scaled bitmap instead of original bitmap.

Listview Pagination in android

I have a listview where I have 50 elements being displayed. I have decided to paginate the view so on each part of the view there are 10 elements and then a next button is clicked to get to the next 10 elements. How can i set 10 data ? I follow this article

You can check my listadapter and i have implemented the same concept to set the text color in two ways
private class CustomerAdapter extends ArrayAdapter<RouteTrackerUser>
{
Context context;
int textViewResourceId;
private ArrayList<RouteTrackerUser> originalitems;
public CustomerAdapter(Context context, int textViewResourceId, ArrayList<RouteTrackerUser> items) {
super(context, textViewResourceId, items);
this.textViewResourceId = textViewResourceId;
this.context = context;
this.originalitems = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
v = inflater.inflate(textViewResourceId, parent, false);
}
final RouteTrackerUser r = originalitems.get(position);
if (r != null) {
TextView textName= (TextView) v.findViewById(R.id.sname);
TextView postal=(TextView) v.findViewById(R.id.postal);
if(r.getVisited().equals("true"))
{
if(textName != null)
{
textName.setTextColor(getResources().getColor(R.color.lightpurple));
textName.setText(r.getStorename());
}
if(postal != null)
{
postal.setTextColor(getResources().getColor(R.color.lightpurple));
postal.setText("Address: "+r.getPostalcode());
}
}
if(r.getVisited().equals("false"))
{
if(textName != null)
{
textName.setTextColor(getResources().getColor(R.color.darkpurple));
textName.setText(r.getStorename());
}
if(postal != null)
{
postal.setTextColor(getResources().getColor(R.color.darkpurple));
postal.setText("Address: "+r.getPostalcode());
}
}
if(RouteTrackerApp.sharedPreference.getInt(RouteTrackerApp.SHARED_ACCESS_UTYPE, 0) == Constants.VAR_TYPE_SALES_PERSON){
v.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
viewdata(r.getUsername(),r.getStoreid(),r.getAccountid(),r.getUid(),r.getVisitplanid(),r.getVisited(),r.getStorename());
}});
}
}
return v;
}
}
and on PostExecute i called this adapter like
protected void onPostExecute(ArrayList<RouteTrackerUser> result)
{
if(result!=null)
{
// System.out.println("User with result===>"+result);
/*for(RouteTrackerUser r :result ){
System.out.println("StoreName===>"+r.getStorename());}*/
Intent intent=getIntent();
TextView username=(TextView)findViewById(R.id.usrname);
final String sname=intent.getExtras().getString("user_name");
username.setText("Welcome, "+sname);
TextView todayvisits=(TextView)findViewById(R.id.todaylist);
todayvisits.setText("TODAY'S STORE VISITS");
userAdapter = new CustomerAdapter(ViewYourPlanList.this, R.layout.view_your_plan_list,result);
userList = (ListView) findViewById(R.id.listview);
userList.setItemsCanFocus(false);
userList.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
userList.setAdapter(userAdapter);
dialog.dismiss();
}
else
if you are want to implement in listfragment ! Design a customadapter and set the text color like i shown below and call this customadapter on postexecute.
public class CustomAdapter extends ArrayAdapter<Model> {
private final LayoutInflater mInflater;
public CustomAdapter(Context context) {
super(context, android.R.layout.simple_list_item_2);
mInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void setData(List<Model> data) {
clear();
if (data != null) {
for (Model appEntry : data) {
System.out.println("cust adptr set data: "+appEntry.getStorename());
add(appEntry);
}
}
}
/**
* Populate new items in the list.
*/
#SuppressLint("SimpleDateFormat")
#Override public View getView(int position, View convertView, ViewGroup parent) {
View view;
if (convertView == null) {
view = mInflater.inflate(R.layout.view_your_plan_weekly, parent, false);
} else {
view = convertView;
}
Model item = getItem(position);
int dayVal = Calendar.getInstance().get(Calendar.DAY_OF_WEEK)-1;
ImageView arrow=(ImageView)view.findViewById(R.id.arrow_image);
arrow.setVisibility(View.INVISIBLE);
if(item.getTabId().equals(String.valueOf(dayVal))){
arrow.setVisibility(View.VISIBLE);
}
if(item.getVisited().equals("true"))
{
((TextView)view.findViewById(R.id.sname)).setText(item.getStorename());
((TextView)view.findViewById(R.id.postal)).setText(item.getPostal());
((TextView)view.findViewById(R.id.sname)).setTextColor(Color.parseColor("#D397D4"));
((TextView)view.findViewById(R.id.postal)).setTextColor(Color.parseColor("#D397D4"));
}
if(item.getVisited().equals("false"))
{
((TextView)view.findViewById(R.id.sname)).setText(item.getStorename());
((TextView)view.findViewById(R.id.postal)).setText(item.getPostal());
((TextView)view.findViewById(R.id.sname)).setTextColor(Color.parseColor("#9B419B"));
((TextView)view.findViewById(R.id.postal)).setTextColor(Color.parseColor("#9B419B"));
}
return view;
}
}

Remove this part

R.id.accurrent7, R.id.acvoltage7});
// updating listviews
setListAdapter(adapter);
and instead of SimpleAdapter you use customadapter. In CustomAdapter you can set the textcolor as i shown in my previous post.Just go through the class "public class CustomAdapter extends ArrayAdapter "
