Android: Data in grid view appearing with delay

Android: Data in grid view appearing with delay - android

In my app, I have requirement of showing calendar. Since, calendar view is available from API level 11, so, I used grid view instead. Basically, I follwed this tutorial. Calendar is working, but data in Calendar in appearing with delay, means, when I click on button to display the calendar, it comes up after delay of around 5-10 seconds. I even tested with disabling the log, which I have put in the program, but it didn't made any difference. I am posting my code below.
Calendar Adapter
public class CalendarAdapter extends BaseAdapter //implements OnClickListener
{

public CalendarAdapter(Context c, Calendar monthCalendar, TextView txtCurMonth)
{

selectedDate = (Calendar)monthCalendar.clone();

month.set(Calendar.DAY_OF_MONTH, 1);
new ArrayList<String>();
this.txtCurMonth = txtCurMonth;

curMonth = selectedDate.get(Calendar.MONTH) + 1;
refreshDays();

In my calendar, I have to highlight the dates which have some event. And, on click of highlighted date, it will show the list of events on that date. Every thing is working. except the calendar appears with delay even if I change month. I am not getting the cause.

One of the possible causes of the delay may be the call to Typeface.createFromAsset() which is called for every cell. The createFromAsset() method consumes a lot of resources.
To mitigate this, you could create a singleton class that retains the typeface used, so the font is not generated from the font file every time. Or you initialize it in onCreate() and pass it as an argument to the CalendarAdapter constructor and then use that instance in getView().
(To test this assumption comment the lines that sets the font to txtCurMonth TextView, and see if any difference)

My custom ArrayAdapter only repeats a few items

I'm using it for grid view, the count of object displayed is correct and it's returning in log is correct but for example 6 object display and the rest repeat them
1,2,3,4,5,6, 1,2,3,4,5,6,.....
my code
public class CustomAdapter extends ArrayAdapter<ItemObject> {
private static float textViewWidth;
public CustomAdapter(ArrayList<ItemObject> array, float textViewWidth) {
super(G.context, R.layout.sample_album_item, array);
CustomAdapter.textViewWidth = textViewWidth;
}
private static class ViewHolder {
ImageView imgScreenShot;
TextView txtAlbumName;
TextView txtAlbumAuthor;
public ViewHolder(View view) {
imgScreenShot = (ImageView) view.findViewById(R.id.screen_shot);
txtAlbumName = (TextView) view.findViewById(R.id.album_name);
txtAlbumAuthor = (TextView) view.findViewById(R.id.album_author);
}
public void fill(final ArrayAdapter<ItemObject> adapter, final ItemObject item, final int position) {
imgScreenShot.setImageResource(item.getScreenShot());
String albumName = item.getAlbumName();
String albumAuthor = item.getAlbumAuthor();
float musicNameWidthSizeViaParent = widthSizeViaParent(txtAlbumName, albumName);
float musicAuthorWidthSizeViaParent = widthSizeViaParent(txtAlbumAuthor, albumAuthor);
if (musicNameWidthSizeViaParent < 0) {
for (int i = 1; i < albumName.length() - 1; i++) {
if (widthSizeViaParent(txtAlbumName, albumName.substring(0, i).trim() + "...") < 0) {
albumName = albumName.substring(0, i - 1).trim() + "...";
break;
}
}
}
if (musicAuthorWidthSizeViaParent < 0) {
for (int i = 1; i < albumAuthor.length() - 1; i++) {
if (widthSizeViaParent(txtAlbumName, albumAuthor.substring(0, i).trim() + "...") < 0) {
albumAuthor = albumAuthor.substring(0, i - 1).trim() + "...";
break;
}
}
}
txtAlbumName.setText(albumName);
txtAlbumAuthor.setText(albumAuthor);
}
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
ItemObject item = getItem(position);
if (convertView == null) {
convertView = G.inflater.inflate(R.layout.sample_album_item, parent, false);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.fill(this, item, position);
return convertView;
}
private static float widthSizeViaParent(TextView text, String newText) {
float textWidth = text.getPaint().measureText(newText);
return textViewWidth - (textWidth * G.displayMetrics.density);
}
}
if getView method without this (convertView == null) condition, everything is correct but scrolling is slowly

My guess is that this block of code makes it run slow:
public void fill(final ArrayAdapter<ItemObject> adapter, final ItemObject item, final int position) {
imgScreenShot.setImageResource(item.getScreenShot());
String albumName = item.getAlbumName();
String albumAuthor = item.getAlbumAuthor();
float musicNameWidthSizeViaParent = widthSizeViaParent(txtAlbumName, albumName);
float musicAuthorWidthSizeViaParent = widthSizeViaParent(txtAlbumAuthor, albumAuthor);
if (musicNameWidthSizeViaParent < 0) {
for (int i = 1; i < albumName.length() - 1; i++) {
if (widthSizeViaParent(txtAlbumName, albumName.substring(0, i).trim() + "...") < 0) {
albumName = albumName.substring(0, i - 1).trim() + "...";
break;
}
}
}
if (musicAuthorWidthSizeViaParent < 0) {
for (int i = 1; i < albumAuthor.length() - 1; i++) {
if (widthSizeViaParent(txtAlbumName, albumAuthor.substring(0, i).trim() + "...") < 0) {
albumAuthor = albumAuthor.substring(0, i - 1).trim() + "...";
break;
}
}
}
txtAlbumName.setText(albumName);
txtAlbumAuthor.setText(albumAuthor);
}
Two loops runs for every single item. You probably want to have that logic in the models instead. So when rendering the items, albumName and albumAuthor is already set.

listview not updated baseadapter

i working baseadapter.
i have two datetimeformat 09/01/2014 and 09/10/2014.i checked days between there datetimes
public String getDateDiffString(Date dateOne, Date dateTwo)
{
long timeOne = dateOne.getTime();
long timeTwo = dateTwo.getTime();
long oneDay = 1000 * 60 * 60 * 24;
long delta = (timeTwo - timeOne) / oneDay;
if (delta > 0) {
for (int i = 0; i < delta; i++) {
}
return String.valueOf(delta) ;
}
else {
delta *= -1;
return String.valueOf(delta);
}
}
and also i wrote funtciton to change there datetimes format 09/01/2014 i changed it 1 Sep
public static String dateFormatterforLukka(String inputDate,int lenght) {
String inputFormat = "MM/dd/yyyy";
String outputFormat = String.valueOf(lenght)+"MMM";
Date parsed = null;
String outputDate = "";
try {
SimpleDateFormat df_input = new SimpleDateFormat(inputFormat,
new Locale("en", "US"));
SimpleDateFormat df_output = new SimpleDateFormat(outputFormat,
new Locale("en", "US"));
parsed = df_input.parse(inputDate);
outputDate = df_output.format(parsed);
Log.wtf("outputDate", outputDate);
} catch (Exception e) {
outputDate = inputDate;
}
return outputDate;
}
now i want to add my datetimes in listview like this .betweeen days there two datetimes . 1 Sep,2 Sep etc...

when i run my app only 8 sep added always in my listview ,but i loged and in log i have
different result, meybe listview did not updated
what am i doing wrong? if anyone knows solution please help me

Create a methord in adapter class
public void setdata(ArrayList<CinemaInfoModel> hollitems_temp) {
this.hollitems=hollitems_temp;
}
for (int l = 0; l < abc; l++) {
String ab = dateFormatterforLukka(timeJsonArray
.getJSONObject(k).getString("start_time"),l++);
Log.wtf("timeeeeeeeee", ab);
cinemaTime.setStartTime(ab);
cinemaTime.setEndTime(_s1);
cinemaTimesArray.add(cinemaTime);
}
after this loop i am assuming that cinematimesarray is of type CinemaInfoModel
youradapter.setdata(cinemaTimesArray);
youradapter.notifyDataSetChanged();
put debugger in your getview methord and check;

Missing data in Section list view in Android?

I am working with Section list view in Android to show Call details according to date.
Means under a particular date number of call details. But when I get 2 calls under the same date, the last date is visible only and the list does not show the rest of the calls of that date.
Calls under different dates are shown correctly but calls under same date are not shown correctly, only the last call is shown.
I am using the below code:

How to get previous month's days on the gridview (Calendar)

I need help on how to go about and make prev month's days visible (grayed out) on this calendar.
I am getting a present months view here.. but as you can see the previous months days are not visible.I know why.. but how to go about it? also few bugs are there in this present one as well.please help.Posting the code for the custom adapter class:
CalendarAdapter.java
import java.util.ArrayList;
import java.util.Calendar;

public void refreshDays()
{
// clear items

and this is the Activity code on how i am using this adapter:
CalendarView.java
/*some code above*/
/*this is in the OnCreate block*/
adapter = new CalendarAdapter(this, month);
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(adapter);
/*some code below*/
and heres my calendar view screen (grid):
CalendarView Screenshot:
To be straight and to the point,All i want is that blank boxes before 1st of the month be filled in with the previous month's last week's days

Declare another calendar
private java.util.Calendar month, prevMonth;
Add a clone to calendar in the constructor
prevMonth = (Calendar) month.clone();
prevMonth.roll(Calendar.MONTH, false);
Then replace the refreshDays with this one.This fills up the blank spaces with the days from the last month and the next month for the first and last week of the current month respectively.
public void refreshDays() {
// clear items
items.clear();
int lastDay = month.getActualMaximum(Calendar.DAY_OF_MONTH);
int firstDay = (int) month.get(Calendar.DAY_OF_WEEK);
int maxweek = month.getActualMaximum(Calendar.WEEK_OF_MONTH);
Log.d("CalendarAdapter", String.valueOf(maxweek));
// figure size of the array
/*
* if (firstDay == 1) { days = new String[lastDay + (FIRST_DAY_OF_WEEK *
* 6)]; }
*
* else { days = new String[lastDay + firstDay - (FIRST_DAY_OF_WEEK +
* 1)]; }
*/
days = new String[maxweek * 7];
int j = FIRST_DAY_OF_WEEK;
// populate empty days before first real day
if (firstDay > 1) {
// can be made a bit faster if implemented without this following
// for loop for roll
for (j = 0; j < firstDay - FIRST_DAY_OF_WEEK; j++) {
prevMonth.roll(Calendar.DAY_OF_MONTH, false);
Log.d("CalendarAdapter",
"roll block: " + prevMonth.get(Calendar.DAY_OF_MONTH));
}
for (j = 0; j < firstDay - FIRST_DAY_OF_WEEK; j++) {
// days[j] = "";
prevMonth.roll(Calendar.DAY_OF_MONTH, true);
int dayPrev = prevMonth.get(Calendar.DAY_OF_MONTH);
days[j] = " " + String.valueOf(dayPrev) + " ";
Log.d("CalendarAdapter", "calculation:J if firstDay>1 -- " + j
+ " roll gives:" + dayPrev);
}
} else {
for (j = 0; j < FIRST_DAY_OF_WEEK * 6; j++) {
days[j] = "";
Log.d("CalendarAdapter", "calculation:J if firstDay<1 -- " + j);
}
j = FIRST_DAY_OF_WEEK * 6 + 1; // sunday => 1, monday => 7
}
// populate days
int dayNumber = 1;
boolean flag = false;
for (int i = j - 1; i < days.length; i++) {

I am new to programming and I'm making a very simple blackjack game with only basic functions. When I run the program on the emulator it runs maybe for one hand, two, sometimes 5 or more but it always stops responding at some stage when i click on one of the three butons. There is a splash screen that runs for three seconds and the there is a thread comming from that activity that starts this menu activity. Could anyone maybe tell why this is happening? It usually happens when I clcik on one of the buttons even though there is no much comput

Use the debugger in eclipse to find out where it gets frozen.
Also the android emulator is very slow even with a fast PC.

Try using the low resolution simulators.
open DDMS from the android-sdk\tools and check which method or thread is taking more time to execute.
Use AsyncTask or Handler when there is a functional(Computational) things running.
