How to get all homescreens in Android? - android

I am new to android development. I know that every homescreen is a Workspace in Launcher. I want to get all the position info of all application icons on the screen, so is there any way to get a list of these screen objects and their icon info?
ADD: What I expect more is the relationships between app icon and screen. For example, I want the position info of a certain app icon, including which screen it appears on(that is the index of the screen list).


first create a bean to store app info like this
public class Bean {
String appName;
String packName;
Drawable icon;
Date installTime;
Date updateTime;
int size;
}
now create four list here for ApplicationInfo,results,packname,bean.
public class AllApplications extends Activity {
List<ApplicationInfo> AppList;
private ArrayList<String>results;
private ArrayList<String>packName;
public ArrayList<Bean> list;
ProgressDialog progress;
ActivityManager am ;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_all_applications);
try
{
new LoadApps().execute();
}
catch (Exception e)
{
// TODO Auto-generated catch block
e.printStackTrace();
Log.e("Exception",e.toString());
}
}
class LoadApps extends AsyncTask<Void, Void,String>
{
#Override
protected void onPreExecute() {
progress= ProgressDialog.show(AllApplications.this,"Loading",
"Please Wait");
}
#Override
protected String doInBackground(Void... params)
{
PackageManager pm = AllApplications.this.getPackageManager();
list = new ArrayList<Bean>();
AppList = new ArrayList<ApplicationInfo>();
AppList = pm.getInstalledApplications(0);
Log.e("Package info",""+AppList);
results = new ArrayList<String>();
packName = new ArrayList<String>();
Log.e("Total package list",""+AppList.size());
for(int i=0;i<AppList.size();i++)
{
Bean bean = new Bean();
ApplicationInfo appInfo = AppList.get(i);
try
{
PackageInfo packInfo = pm.getPackageInfo(appInfo.packageName,0);
try
{
java.lang.reflect.Field field1 = PackageInfo.class.getField("firstInstallTime");
long firstIns = field1.getLong(packInfo);
Date insDate = new Date(firstIns);
bean.installTime = insDate;
java.lang.reflect.Field field2 = PackageInfo.class.getField("lastUpdateTime");
long lastUpdate = field2.getLong(packInfo);
Date upDate = new Date(lastUpdate);
bean.updateTime = upDate;
}
catch (NoSuchFieldException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
catch (NameNotFoundException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.e("ins package", "" + appInfo.packageName);
Log.e("ins package name", "" +appInfo.loadLabel(pm));
Log.e("launched activity :", "" + pm.getLaunchIntentForPackage(appInfo.packageName));
bean.appName = (String) appInfo.loadLabel(pm);
bean.packName = appInfo.packageName;
bean.icon = appInfo.loadIcon(getPackageManager());
list.add(bean);
// PackageInfo. this.firstInstallTime(a);
}
return null;
}
#Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
progress.dismiss();
}
}}
Try this it ll help you alot,and let me know for more help.

set fetched data from database to a textview after calling intent

I've created a Textview with a null value and button in my my Mainactivity and fetched some data from sql database server using AsyncTask method on button click and stored in to my textview. Then I called an intent to another activity activity2 to show something and I returned to my Mainactivity using intent.But I can't view the previously set data in textview. It shows null value.I want to set it previously fetched data.how can I set that?
public class MainActivity extends Activity {

} catch (SQLException e1) {
e1.printStackTrace();
}
} catch (SQLException e) {
e.printStackTrace();
}
Log.d("status", String.valueOf(status));
return status;
}
}

Whenever you wish to go to previous screen, Always finish the Activity that is on top. Here in your case, You are always creating new instance of MainActivity and this is the reason for getting null when you go back. Try using this in your StatusUpdate.java.
visited.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Visit vt= new Visit();
vt.execute();
StatusUpdate.this.finish();
}
});
notvisited.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
NotVisit n = new NotVisit();
n.execute();
StatusUpdate.this.finish();
}
});

You can store the retrieved text in a static field of your activity class, but it's better save and restore it on activity recreation.So modify your activity like:
#Override
public void onCreate(Bundle b) {
// activity initialization
// textView = ...
if (b != null) {
textView.setText(b.getString("dbtext"));
}
}
and
#Override
protected void onSaveInstanceState(Bundle b) {
super.onSaveInstanceState(b);
b.putString("dbtext", textView.getText());
}

Spinner OnItemSelectedListener in Custom adapter Listview call recursively without selecting any item

I have custom adapter list view with two spinner view.
Each spinner has a background process. On initializing, the spinner view.OnItemSelectedListener is recursively called unnecessarily without any external input to the listener

How to avoid unnecessarily calling of view.OnItemSelectedListener of spinner view On initializing custom adapter list view

You can't stop or avoid calling of onItemSelectedListener on initialization. But you can prevent this by declare an integer and set value as 0 and while on calling getview method, check the integer with size of data(Your array list size).if the integer is less than the size than increment the integer value else do your background work. But it's not right way to do because when you scroll the listview the same problem rise again. You do this if you have fixed array list size. It is better to use AutoCompleteTextView instead of SpinnerView.

It gets called for the selection of the first item(Kind of default value).
Try one thing don't set adapter to spinner if row!=null for ex:
if (row == null) {
holder = new ClientListHolder();
row = inflater.inflate(layoutResourceId, parent, false);
holder.tv_no = (TextView) row
.findViewById(R.id.tv_clientwaitlayout_no);
holder.tv_name = (TextView) row
.findViewById(R.id.tv_clientwaitlayout_name);
holder.tv_status = (Spinner) row
.findViewById(R.id.tv_clientwaitlayout_status);
holder.tv_therapist = (Spinner) row
.findViewById(R.id.tv_clientwaitlayout_therapist);
holder.iv_edit=(ImageView) row.findViewById(R.id.btn_clientwaitlayout_edit);
holder.iv_action = (ImageView) row
.findViewById(R.id.btn_clientwaitlayout_action);
holder.tv_unchange_therapist=(TextView) row.findViewById(R.id.tv_clientwaitlayout_unchange_name);
holder.tv_unchange_status=(TextView) row.findViewById(R.id.tv_clientwaitlayout_unchange_status);
holder.tv_therapist.setAdapter(TherapistAdapter);
holder.tv_status.setAdapter(StatusAdapter);
row.setTag(holder);
} else {
holder = (ClientListHolder) row.getTag();

Closed 10 years ago.
I have a custom list view that is getting data from server and changing its content after each 3 seconds.this list view i am using for showing the visitor list who are visiting the site.Each row of list contains ipaddress,statustext,duration time,noofvisit and button text and data is updating and changing in list this part is working fine.For showing this list i am writing custom adapter for this.
Actually i have an issue i have to show the row on the top if status text is chat request.How can i do this?can anyone help me?
Actually i am using tabhost after login screen tabhost contains four tabs.First used for monitoring window that show list of visitor and other are chat window,operatorlist and controls.
As i define above if i got status chat request then that row should appear on the top and will contains two button Accept and deny and on accept button click a window will open for chat and deny will use for refusing chat.
Can anyone help me for solving this issue?

ArrayList<String> userList = your list of data
// other list also
//userListA
//userListB
ArrayList<String> tempUserList = new ArrayList<String>();
// other list also
//tempuserListA
//tempuserListB
String text = "ChatRequest";
// to add CharRequest at top
for(int i=0;i<userList.size();i++)
{
if(userList.get(i).equals(text))
{
tempUserList.add(userList.get(i));
//tempuserlistA.add(userlistA.get(i));
//tempuserlistB.add(userlistB.get(i));
}
}
// to add other entry
for(int i=0;i<userList.size();i++)
{
if(!userList.get(i).equals(text))
{
tempUserList.add(userList.get(i));
//tempuserlistA.add(userlistA.get(i));
//tempuserlistB.add(userlistB.get(i));
}
}
//now temp list are you original list to use
userList = tempUserList;
//userListA = tempuserlistA;
//userListB = tempuserlistB;
// and then call your adapter with the arraylists

You can use an ArrayList holding your Data for the ListView and add an item at the beginning of the list by: myArrayList.add(0, newItem).
Below an example Adapter which can do this:
public class PlaylistAdapter extends BaseAdapter {
private Context context;
private List<Playlist> entries;
public PlaylistAdapter(Context context, List<Playlist> entries) {
this.context = context;
this.entries = entries;
}
public void add(Playlist item) {
if (entries.contains(item))
return;
entries.add(item);
this.notifyDataSetChanged();
}
public void add(int index, Playlist item) {
if (entries.contains(item))
return;
entries.add(index, item);
this.notifyDataSetChanged();
}
#Override
public int getCount() {
return entries.size();
}
#Override
public Playlist getItem(int arg0) {
return entries.get(arg0);
}
#Override
public long getItemId(int arg0) {
return arg0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// inflate the layout you want to use for a single entry row
convertView = inflater.inflate(R.layout.playlists_adapter_entry,
null);
}
// fetches the current item
Playlist playlist = getItem(position);
// fill the entry layout with data
ImageView cover = (ImageView) convertView
.findViewById(R.id.playlist_adapter_entry_cover);
cover.setImageBitmap(playlist.getCover());
TextView title = (TextView) convertView
.findViewById(R.id.playlist_adapter_entry_title);
title.setText(playlist.getTitle());
return convertView;
}
}

How to put custom listview row that has specific text on the top row in listview in android

I have a custom list view that is getting data from server and changing its content after each 3 seconds.this list view i am using for showing the visitor list who are visiting the site.Each row of list contains ipaddress,statustext,duration time,noofvisit and button text and data is updating and changing in list this part is working fine.
Actually i have an issue i have to the row on the top as first row of listview if status text is chat request.How can i do this?can anyone help me?
Actually i am using tabhost after login screen tabhost contains for tab one for monitoring window that show list of visitor and other are chat window,operatorlist and controls.
As i define above if i got status chat request then that row should appear on the top and will contains two button Accept and deny and on accept button click a window will open for chat and deny will use for refusing chat.
Can anyone help me for solving this issue?

what can i do for setting the row that has chat request on the top?Can anyone help me?

Create you customListItem with visibility set to View.GONE by default. When you have a chat request, then just change its visibility to View.VISIBLE and refresh your list. Simple.

If you want to add some view as the first row of your listview, then use
listview.addHeaderView(myHeaderView);
use this before setting list adapter.

try like this..
boolean bool=true;
new Thread(new Runnable() {
public void run() {
while(bool){
int t=StatusText.IndexOf(chat)
if(t!=-1)
{
Collections.swap(StatusText,0,t);
Collections.swap(SessionText,0,t);
Collections.swap(IPText,0,t);
Collections.swap(DurationText,0,t);
Collections.swap( NoOfVisit ,0,t);
Collections.swap(ButtonText,0,t);
}
runOnUiThread(new Runnable() {
public void run() {
adapter.notifyDataSetChanged();
}
});
