Why does not this AlertDialog dismiss in this situation?

I want to insert data from a text file into SQLite database :
public class SyncActivity extends Activity {
...
private MessageDialogView dlg = null; // an AlertDialog showing a message
private Patienter wait = null; // an AlertDialog containing an imageview showing an animation-list
...
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.synchro);
...
dlg = new MessageDialogView(SyncActivity.this, getLayoutInflater());
wait = new Patienter(SyncActivity.this, getLayoutInflater());
...
}
public void synchroniser(View view) { // called when a button is clicked
wait.show();
new RequestTask().execute("http://192.168.1.8/impots/data/syncro/webVersAndroid/parcelles.txt");
}
private class RequestTask extends AsyncTask<String, Void, Void> {
private String err = "";
private boolean error = false;
private String[] enregs;
#Override
protected Void doInBackground(String... s_url) {
enregs = new String[s_url.length];
ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
if(networkInfo != null) {
if (networkInfo.isAvailable() && networkInfo.isConnected()) {
System.setProperty("http.keepAlive", "false");
HttpURLConnection con = null;
BufferedReader reader = null;
for (int u=0; u<s_url.length; u++) {
String tmp;
String lines = "";
try {
URL url = new URL(s_url[u]);
if (url != null) {
con = (HttpURLConnection) url.openConnection();
if (con != null && con.getResponseCode() == HttpURLConnection.HTTP_OK) {
InputStream in = con.getInputStream();
reader = new BufferedReader(new InputStreamReader(in));
boolean firstLine = true;
while ((tmp = reader.readLine()) != null) {
if (firstLine) {
firstLine = false;
lines += tmp;
}
else
lines += "\r\n" + tmp;
}
enregs[u] = lines;
}
}
} catch (MalformedURLException e) {
error = true;
err = getResources().getString(R.string.errBadUrl);
} catch (IOException e) {
error = true;
err = getResources().getString(R.string.errAccessError);
} finally {
if (reader != null) {
try {
reader.close();
} catch (IOException e) {
}
}
if (con != null)
con.disconnect();
}
}
}
else {
error = true;
err = getResources().getString(R.string.errNotConnected);
}
} else {
error = true;
err = getResources().getString(R.string.errNoNetwork);
}
return null;
}
#Override
protected void onPostExecute(Void result) {
if (error) {
wait.dismiss();
displayError(err);
} else {
populateDB();
wait.dismiss();
}
}
private void displayError(String msg) {
dlg.setTitre(getString(R.string.titreErrMsgBox));
dlg.setMsg(msg);
dlg.show();
}
private void populateDB() {
String[] enreg = SpliterString.Split(enregs[0], "\r\n"); // get each record of "parcelle"
db = new Db(SyncActivity.this).open();
for (int p=0; p<enreg.length; p++) {
Parcelle parcelle = new Parcelle(SpliterString.getColumnValueAt(enreg[p],0),
SpliterString.getColumnValueAt(enreg[p],1),
SpliterString.getColumnValueAt(enreg[p],2),
SpliterString.getColumnValueAt(enreg[p],3),
SpliterString.getColumnValueAt(enreg[p],4),
SpliterString.getColumnValueAt(enreg[p],5),
SpliterString.getColumnValueAt(enreg[p],6),
SpliterString.getColumnValueAt(enreg[p],7),
SpliterString.getColumnValueAt(enreg[p],8),
SpliterString.getColumnValueAt(enreg[p],9),
SpliterString.getColumnValueAt(enreg[p],10),
SpliterString.getColumnValueAt(enreg[p],11),
SpliterString.getColumnValueAt(enreg[p],12),
SpliterString.getColumnValueAt(enreg[p],13),
SpliterString.getColumnValueAt(enreg[p],14));
db.insertParcelle(parcelle);
}
db.close();
}
}
}
Data inside the text file is just one row ( data are represented like a csv but separator is | ) :
1||010-01-02|PARC-0001|PARCELLE DROUDOUDOU|10||2000.00|500.00|1500.00||10, Av Place de l'Independance - CENTRE VILLE|01/02/2000|10/02/2005|CENTRE VILLE|
The problem is that the AlertDialog is never dismissed ! There is no error ! So what is wrong ?

Even if I write just this line inside the onPostExecute then the dialog does not dismiss :
#Override

wait.dismiss();
}

#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
}
#Override
protected Void doInBackground(String... s_url) {

}
#Override

pp.dismiss();
}
}
//=========================================//
public class Main extends Activity {
/** Called when the activity is first created. */
Patienter pp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main); // This needs to be done before
// trying to findViewById
final View vv = findViewById(R.id.my_webview);
vv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
pp = new Patienter(Main.this, getLayoutInflater());

new Handler().postDelayed(new Runnable() {
#Override
public void run() {

new RequestTask().execute();
}
}, 5*1000);
}
});
}
Its working in my project.
please use wait.dismiss(); before if condition in onPostExecute() method.

When running, an error occured, Here is the logcat
Please help me .
Thank you

Are you sure the "context" you are using here is not null ?
How about rewriting the open() function this way and calling it via open(getApplicationContext()); ?
public DatabaseOperations open(Context context) throws SQLException {
ourHelper = new DatabaseOperations(context);
ourDatabase = ourHelper.getWritableDatabase();
return this;
}

Getting a unique row in SQLite

I am trying to search an item in sqlite by using String, & trying to return description contained in that row. items are stored in the table named Articles with column name A_name, Description column name is AS_name
This is my code, the cursor is not null, but the while loop is not getting executed once
public String searchData(String text)
{
Cursor cursor = sdb.query("Articles", new String[] {"A_name","AS_name"}, " A_name=?",new String[]{text}, null, null, null);
Log.e("running", "cursor run");
String temp = null,temp2 = null;
if(cursor!=null)
{
Log.e("running", "curosr is not null");
while(cursor.moveToFirst())
{
Log.e("running", "curosr while loop enter");
temp = (cursor.getString(cursor.getColumnIndex("A_name")));
//temp2 =(cursor.getString(cursor.getColumnIndex("AS_name")));
Log.e("running", "id email" +temp+ " name"+temp2);
}
}
return temp;
}
I want to return the corresponding element of AS_name, also I am confused what should I wrote in while loop ?
Can anyone please identify my mistake, Thanks in advance...

UPDATE after implementing rajaji answer, I got this error :

try this it will help you
create the raw query for getting the data
public String searchData(String text)
{
String strvalue=null;
SQliteDatabase db=this.getwritabledatabase();
Cursor cur=null;
String strquery="select * from youurtablename where A_name="+text;
cur=db.rawQuery(strquery,null);
if(cur!=null&&cur.moveToFirst())
{
do
{
strvalue=cur.getString(0);
}
while(cur.moveToNext());
}
}
let me inform once you complete

Is your Uri correct??
create Uri depends on your package name and table name, like the code below :
private static final String AUTHORITY = "com.sample.test_db_provider";
private static final String BASE_PATH = "Tables";
private static final Uri Sample_URI = Uri.parse("content://" + AUTHORITY
+ "/" + BASE_PATH
+ "/SampleTable");
Then in your get Method, query the db like the below code with Uri

I use the inline where clause but you can do it your way with a parameter. Is this what you are looking for?

Using listviews with a database

and good day. My project is having 2 activities, first one to insert data into the database which works well, but then I want to show a list view of the data within the database in another activity.
I've tried local data eg fred, george in an array and the list view works great however, when I try to use the database. The activity crashes. It seems that I am unable to use "database.open"
public class MyListActivity extends Activity{
DatabaseAdapter database;
//Creates item_details based on the ListItemDetails class
ListItemDetails item_details;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
//Uses the arraylist and set the result
ArrayList<ListItemDetails> result = GetSearchResults();
ListView lv = (ListView)findViewById(R.id.listView1);
lv.setAdapter(new CustomListAdapter(getApplicationContext(),result));
}
private ArrayList<ListItemDetails> GetSearchResults() {
ArrayList<ListItemDetails> results = new ArrayList<ListItemDetails>();
item_details = new ListItemDetails();
/*
database.open();
Cursor c = database.getAllContacts();
if (c.moveToFirst())
{
do {
item_details.setFirstName(c.getString(1));
results.add(item_details);
} while (c.moveToNext());
}
*/
return results;
}
}
Here is the main activity. The database opens fine when I use the buttonShow, so I tried buttonTest and storing them into the list but it got a bit confusing for me.
public class FamousPersonActivity extends Activity {
EditText editFirstName, editLastName;
Button buttonAdd, buttonShow, buttonTest;
ListView lv;
ListItemDetails item_details;
DatabaseAdapter database;
int request_Code = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_famous_person);
database = new DatabaseAdapter(this);
lv = (ListView)findViewById(R.id.listView1);
//ArrayList<ListItemDetails> result = GetSearchResults();
//lv.setAdapter(new CustomListAdapter(getApplicationContext(),result));
editFirstName = (EditText)findViewById(R.id.editFirstName);
editLastName = (EditText)findViewById(R.id.editLastName);
buttonAdd = (Button)findViewById(R.id.buttonAdd);
buttonShow = (Button)findViewById(R.id.buttonShow);
buttonTest = (Button)findViewById(R.id.buttonTest);
buttonAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Toast.makeText(getApplicationContext(), "added to database", Toast.LENGTH_SHORT).show();
database.open();
long id = database.insertContact("Test Contact", "Test Email") ;
database.close();
}
});
buttonTest.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent("com.id11020260.exercise6part2.MyListActivity");
startActivityForResult(i, request_Code);
}
});
buttonShow.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
try {
String destPath = "/data/data/" + getPackageName() +
"/databases";
File f = new File(destPath);
if (!f.exists()) {
f.mkdirs();
f.createNewFile();
//---copy the db from the assets folder into
// the databases folder---
CopyDB(getBaseContext().getAssets().open("mydb"),
new FileOutputStream(destPath + "/MyDB"));
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
//---get all contacts---
database.open();
Cursor c = database.getAllContacts();
if (c.moveToFirst())
{
do {
DisplayContact(c);
} while (c.moveToNext());
}
database.close();
}
});
}
private ArrayList<ListItemDetails> GetSearchResults() {
ArrayList<ListItemDetails> results = new ArrayList<ListItemDetails>();
item_details = new ListItemDetails();
database.open();
Cursor c = database.getAllContacts();
if (c.moveToFirst())
{
do {
item_details.setFirstName(c.getString(1));
results.add(item_details);
} while (c.moveToNext());
database.close();
}
return results;
}
public void CopyDB(InputStream inputStream,
OutputStream outputStream) throws IOException {
//---copy 1K bytes at a time---
byte[] buffer = new byte[1024];
int length;
while ((length = inputStream.read(buffer)) > 0) {
outputStream.write(buffer, 0, length);
}
inputStream.close();
outputStream.close();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.famous_person, menu);
return true;
}
public void DisplayContact(Cursor c)
{
Toast.makeText(this,
"id: " + c.getString(0) + "\n" +
"Name: " + c.getString(1) + "\n" +
"Email: " + c.getString(2),
Toast.LENGTH_LONG).show();
}
}
This is the stack trace, I'm not sure if this is entirely correct

Try this:-
lv.setListAdapter(new ArrayAdapter(MyListActivity.this,
android.R.layout.simple_list_item_1,result));

Why I don't see record in database from my test project?

Hї!
I have wrote test for my application. I need add item to database throught UI interface (using robotium) and then I want to check if item exists in database using SQLiteDatabase.
Item is added succesfully (I see new record in database after test finished), but isExistsInDb in my test class returns false. I do not understand why. Could you please help me.
Thanks!
Activity class:
public abstract class EditActivity {
// Some code .....
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initButtonCancelOk();
}
protected void validateAndSave() {
try {
formValidator.validateAll();
if (formValidator.isFormValid()) {
DatabaseOpenHelper doh = new DatabaseOpenHelper(this);
Dao d = new Dao(doh);
d.add(fetchObjectFromUi());
finish(); // destroy this activity
} else {
ToastImage.makeImageText(context,
R.drawable.warning,
formValidator.getMessages(),
Toast.LENGTH_SHORT
).show();
}
} catch (Exception e) {
Toast.makeText(context, " Error during validate form ", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
private void initButtonCancelOk() {
btnOk = (Button) findViewById(R.id.btn_ok);
btnOk.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
validateAndSave();
}
});
}
}
Test class:
public class AddItemSmokeTest extends extends ActivityInstrumentationTestCase2<EditActivity> {
protected Activity activity;
protected Solo solo;
public AddItemSmokeTest() {
super("com.myapp", EditActivity.class);
Intent i = createIntent(2);
setActivityIntent(i);

return i;

solo.typeText((EditText) activity.findViewById(com.rirdev.moneycounter.R.id.et_comment), testData.getComment());
}

AbsTransIncomeExpenseTestData testData = new IncomeTestData();
setIncomExpenseData(testData);
solo.clickOnButton(OK);
//solo.getActivityMonitor();
assertTrue(
"Item" + testData.getComment() + " was not added ",
isExistsInDb(activity, Transactions.TABLE_NAME, Transactions.DESCRIPTION, testData.getComment())
);
}
protected static boolean isExistsInDb(Context context, String tableName, String commentFieldName, String comment) {
DatabaseOpenHelper doh = new DatabaseOpenHelper(context);
SQLiteDatabase db = doh.getDatabaseReadable();
Cursor cursor = null;
try {
String query = "SELECT COUNT(*) FROM " + tableName + " WHERE " + commentFieldName + " = \"" + comment + "\"";
cursor = db.rawQuery(query, null);
cursor.moveToFirst();
if (cursor.getInt(0) > 1) {
return true;
}
return false;
} finally {
if (cursor != null) {
cursor.close();
}
db.close();
doh.close();
}
}
}
Update:
If I run test the second time it is passed because in database exists item added by previous test.

I recommend to use use parametrized statement, your approach is danger and not much clear.
Also much better is use getCount() method.
String query = "SELECT COUNT(*) FROM " + tableName + " WHERE columnName = ?";
cursor = db.rawQuery(query, new Sring[] {comment});
int count = 0;
if (cursor.getCount() > 0) {
cursor.moveToFirst();
count = cursor.getInt(0);
}
if (count > 0) {
return true;
}
else {
return false;
}

in where clasue use 'string' instead of "string".....
"SELECT COUNT(*) FROM " + tableName + " WHERE " + commentFieldName + " = '" + comment + "'";
