java.lang.String cannot be cast to java.util.HashMap

When i run the following program:
ArrayList<HashMap<String, String>> AL = new ArrayList<HashMap<String, String>>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_outaccountinfo);
ListView lv = (ListView) findViewById(R.id.lvoutinfo);
ArrayList<HashMap<String, String>> AL = new ArrayList<HashMap<String, String>>();
DBOpen open = new DBOpen(Outaccountinfo.this);
SQLiteDatabase db = open.getWritableDatabase();
Cursor cursor = db.query("outaccount", null, null, null, null, null, null, null);
while (cursor.moveToNext()) {
if (cursor.moveToFirst()) {
do {
HashMap<String, String> map = new HashMap<String, String>();
String str_id = cursor.getString(cursor.getColumnIndex("id"));
String str_money = cursor.getString(cursor.getColumnIndex("outmoney"));
String str_time = cursor.getString(cursor.getColumnIndex("time"));
String str_type = cursor.getString(cursor.getColumnIndex("type"));
String str_mark = cursor.getString(cursor.getColumnIndex("mark"));
map.put("id", str_id);
map.put("outmoney", str_money);
map.put("time", str_time);
map.put("type", str_type);
map.put("mark", str_mark);
AL.add(map);
} while (cursor.moveToNext());
}
}
String[] str = new String[cursor.getCount()];
for (int i = 0; i < cursor.getCount(); i++) {
str[i] = AL.get(i).get("id").toString() + "|" + " " + "money:" + String.valueOf(AL.get(i).get("outmoney"))
+ " " + "time:" + AL.get(i).get("time").toString() + " " + "type:" + AL.get(i).get("type").toString()
+ " " + "mark:" + AL.get(i).get("mark").toString();
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
str);
lv.setAdapter(arrayAdapter);
}
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// TODO Auto-generated method stub
HashMap<String, String> map = (HashMap<String, String>) parent.getItemAtPosition(position);
Toast.makeText(Outaccountinfo.this, map.get("type"), Toast.LENGTH_SHORT).show();
}
});
}
I receive the following error:
java.lang.String cannot be cast to java.util.HashMap
Who can help me to achieve the purpose without changing the purpose of the program?
Thanks!

You are using ArrayAdapter<String> Means that you pass your adapter object of Strings.
Now, when you clicked on your item and asked for parent.getItemAtPosition(position); you get an Object.
If you will go inside this function you can see that the Object that you get is by position and by the type you sent to the Adapter (String).
So, when you try to cast that String to (HashMap<String, String>) you get the exception.
Try to do something like that after you clicked:
HashMap<String, String> map = new HashMap<String, String>(); // Parameter in outside the click listener
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
map.put("someKey", parent.getItemAtPosition(position));
Toast.makeText(Outaccountinfo.this, map.get("type"), Toast.LENGTH_SHORT).show();
}
});

How to set selection in spinner with SimpleAdapter?

I am populating spinner from below code and its working perfect. When user select any value from spinner then I am saving stateCodeId in sqlite. Now what I want that when user come again then I want to show the seleted value from ID which already saved in sqlite. How can I show value selected in spinner ?
public void fillStateData() {
try {
State_data = new ArrayList<Map<String, String>>();
State_data.clear();
Cursor cursor_State = db.rawQuery("SELECT nSerialNo as _id,cCodeName FROM CodeMaster where nCtgId = 6", null);
int i = 0;
if (cursor_State.moveToFirst()) {
do {
Map<String, String> datanum = new HashMap<String, String>();
if (i == 0) {
datanum.put("nStateID", "0");
datanum.put("cStateName", "Select State");
State_data.add(datanum);
datanum = new HashMap<String, String>();
datanum.put("nStateID", cursor_State.getString(0));
datanum.put("cStateName", cursor_State.getString(1));
State_data.add(datanum);
} else {
datanum.put("nStateID", cursor_State.getString(0));
datanum.put("cStateName", cursor_State.getString(1));
State_data.add(datanum);
}
i += 1;
} while (cursor_State.moveToNext());
}
String[] fromwhere = {"nStateID", "cStateName"};
int[] viewswhere = {R.id.txtnStateID, R.id.txtcStateName};
StateAdapter = new SimpleAdapter(getActivity(), State_data, R.layout.state_list_template, fromwhere, viewswhere);
spnState.setAdapter(StateAdapter);
cursor_State.close();
spnState.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
TextView stateId = (TextView) view.findViewById(R.id.txtnStateID);
stateCodeId = stateId.getText().toString();
fillDistrictData(stateCodeId);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
Like this I am getting ID from sqlite.
Cursor c = db.rawQuery("SELECT nStateId from MemberMaster where nCustID ="+SesPMbrID+"", null);
c.moveToFirst();
String state = c.getString(0);

Use
spinner.setSelection(position);

Android - ListView Listener not working after adding multiple item at one time

My listView works well when only 1 item added to the listview at one time. But when multiple item is added, listener in listview is not wokring. Can anyone guide me what i am doing wrong here? Thanks.

You have write custom adapter for multiple items

Handling the Click Event in the ListView

I have a ListView in which there are 20 items . 10 items are contacts of my phone and rest of the 10 are bookmars url of my default browser . What i want is that:
1) when i click on the contacts(first 10) it should take me to that partular contact in contact app.
2)when i click on the bookmark url(rest of the 10) , it should open that url in the browser .
I implemented the first requirement of mine with the following code below :
ArrayList<HashMap<String, Object>> listitem = new ArrayList<HashMap<String, Object>>();
mSharedPrefs = PreferenceManager
.getDefaultSharedPreferences(getApplicationContext());
Boolean contact_check = mSharedPrefs.getBoolean("contact_check", true);
Boolean bookmark_check = mSharedPrefs
.getBoolean("bookmark_check", true);
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, null);
if (contact_check) {
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur
.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer
.parseInt(cur.getString(cur
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id },
null);
while (pCur.moveToNext()) {
String phoneNo = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("name", name);
map.put("phone no", phoneNo);
// map.put("Bookmarks", faves.getString(titleIdx));
listitem.add(map);
}
pCur.close();
}
}
}
}
SimpleAdapter listitemAdapter = new SimpleAdapter(this, listitem,
R.layout.list_style, new String[] { "name", "phone no" },
new int[] { R.id.topTextView, R.id.bottomTextView });
lv.setAdapter(listitemAdapter);
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
RelativeLayout lr = (RelativeLayout) arg1;
TextView mText = (TextView) lr.getChildAt(1);
Intent i = new Intent(Intent.ACTION_VIEW);
i.setAction(ContactsContract.Intents.SHOW_OR_CREATE_CONTACT);
i.setData(Uri
.fromParts("tel", mText.getText().toString(), null));
startActivity(i);
}
});
The above code is adding the contacts in my listview on handling the click event .
For my second requirement i extended my listview with bookmarks , with the following code:
String[] requestedColumns = { Browser.BookmarkColumns.TITLE,
Browser.BookmarkColumns.URL };
#SuppressWarnings("deprecation")
final Cursor faves = managedQuery(Browser.BOOKMARKS_URI, requestedColumns,
Browser.BookmarkColumns.BOOKMARK + "=1", null, null);
Log.d("Bookmarks", "Bookmarks count: " + faves.getCount());
faves.moveToFirst();
int titleIdx = faves.getColumnIndex(Browser.BookmarkColumns.TITLE);
final int urlIdx = faves.getColumnIndex(Browser.BookmarkColumns.URL);
if (bookmark_check) {
while (!faves.isAfterLast()) {
Log.d("SimpleBookmarks", faves.getString(titleIdx));
Log.d("SimpleBookmarks url", " " + faves.getString(urlIdx));
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("name", faves.getString(titleIdx));
map.put("phone no", faves.getString(urlIdx));
listitem.add(map);
faves.moveToNext();
}
Its getting populated but i am not able to handle its click event . I want to open the url in the browser when the user click on it.

with some adaptation to your method:
lv.setOnItemClickListener(new OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3)
{
if (arg2 < 10)
{
RelativeLayout lr = (RelativeLayout) arg1;
TextView mText = (TextView) lr.getChildAt(1);
Intent i = new Intent(Intent.ACTION_VIEW);
i.setAction(ContactsContract.Intents.SHOW_OR_CREATE_CONTACT);
i.setData(Uri.fromParts("tel", mText.getText().toString(), null));
startActivity(i);
}
else
{
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(getCurrentUri));
//getCurrentUri is the uri at position arg2-10
startActivity(browserIntent);
}
}
});

I want to select a number from the contact book in Android

This Code shows the List of Contact Numbers, but i want to select cell number from selected contact display name--->
Cursor cursor= managedQuery(intent.getData(), null, null, null, null);
while(cursor.moveToNext()) {
String contactId=cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
System.out.println("---------ContactId---------"+contactId);
String name=cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
System.out.println("---------NAME---------"+name);
String hasPhone=cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
System.out.println("---------HAS Phone---------"+hasPhone);
ArrayList one= new ArrayList();
ArrayList two= new ArrayList();
// if(Boolean.parseBoolean(hasPhone)) {
Cursor phones=getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID+" = "+ contactId, null, null);
while(phones.moveToNext()) {
phoneNumber= phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
System.out.println("---------Number---------"+phoneNumber);
one.add(phoneNumber);
System.out.println("---------email Address---------"+one);
} phones.close();
