android.content.Context.getContentResolver()' on a null object reference

I can't seem work out why I am getting a null pointer on this?
This is my AsyncTask that I call to grab the data. It passes it to a JSON Parser and an array of Objects is returned. This is then passed to my DBHelper where it was passing to my database through a ContentResolver....
public class getFilms extends AsyncTask<String, Void, Void> {
public int LIMIT_FILMS = 10;
String KEY = "apikey";
String LIMIT = "limit";
private static final String URL = "http://api.rottentomatoes.com/api/public/v1.0/lists/movies/box_office.json?";
private static final String API_KEY = "******************";
ArrayList<HashMap<String, String>> filmArrayList = new ArrayList<HashMap<String, String>>();
Context mContext;
#Override
protected Void doInBackground(String... params) {
Uri RottenUrl = Uri.parse(URL).buildUpon()
.appendQueryParameter(KEY, API_KEY)
.appendQueryParameter(LIMIT, Integer.toString(LIMIT_FILMS))
.build();
JSONParser jParser = new JSONParser();
Film[] json = jParser.getJSONFromUrl(RottenUrl.toString());
sortData(json);
return null;
}

Android SQLite copy values from table to another table

I'm trying to copy some data in a table and insert into another table. I entered the data into an ArrayList, however, is only copied a given and not all those present. What am I missing?
private void Tras() {
String numero_ricevuto = (i.getStringExtra("numero"));
SQLiteDatabase db = mHelper.getWritableDatabase();
final ArrayList<Dettaglio_i> dettaglii = new ArrayList<Dettaglio_i>();
String sql = "SELECT data, unita_di_misura FROM prev WHERE numero = '"+numero_ricevuto+"'";
Cursor c = db.rawQuery(sql, null);
while (c.moveToNext()){
Dettaglio_i e = new Dettaglio_i();
e.data_ = c.getString(0);
e.unita_di_misura = c.getString(1);
dettaglii.add(e);
}
c.close();
ContentValues cv = new ContentValues();
Dettaglio_i e = new Dettaglio_i();
cv.put(VerTable.SI_NO, "0");
cv.put(VerTable .DATA, e.data_);
cv.put(VerTable .U_M, e.unita_di_misura);
boolean inserite = false;
if (!inserite){
long result = db.insert(VerTable .TABLE_NAME, null, cv);
if (result > 0){
inserite = true;
}
}
if (inserite){
}
db.close();
}

Try replacing your code with this:
private void Tras() {
String numero_ricevuto = (i.getStringExtra("numero"));
SQLiteDatabase db = mHelper.getWritableDatabase();
String insert = String.format("INSERT INTO %s (%s, %s, %s) ",
VerTable.TABLE_NAME, VerTable.SI_NO, VerTable.DATA, VerTable .U_M);
String select = "SELECT '0', data, unita_di_misura FROM prev WHERE " +
"numero='"+numero_ricevuto+"'";
db.rawQuery(insert+select, null);
db.close();
}

Read and Write on SQLite Database in Android app_project

I have a java.lang.NullPointer error on the LogCat but I can't figure out why. It seems that the error lay on the second OnClick procedure. Anyone can help me??
package com.example.cinemaodeon;

startActivity(openProgrammazione);
}
}
toast.show();
}
});
Button btnReg = (Button) findViewById(R.id.main_btnregistra);
btnReg.setOnClickListener(new OnClickListener(){
It seems the error lay over below on tho OnClick procedure,maybe there is some problem with the definition of the databaseHelper
#Override
public void onClick(View arg0) {
SQLiteDatabase db = DatabaseHelper.getReadableDatabase();
String[] columns = { "_id_user" };
Cursor cursor = db.query("users", columns, null, null, null, null, null);

int count = cursor.getCount();
while (cursor.moveToNext()) {
result[count]=cursor.getString(0);
count=count+1;
}
EditText editusername =(EditText) findViewById(R.id.main_editusername_registra);
final String username = editusername.getText().toString();
for (int i = 0; i < count; i++) {
if (username==result[count]){
toast2.show();
}
}
SQLiteDatabase dbW = DatabaseHelper.getWritableDatabase();

#SuppressWarnings("unused")

Fetching row columns into edit texts, row id in textview

I have a page with a number edit texts, i want to populate these with columns of a raw with the row id equaling a textview value... this is what i have so far in the edit text page.
public class CBCreate extends Activity {
EditText EditRecipe,EditRecipe2,EditRecipe3;
Button Rname;
CBDataBaseHelper entry;
TextView RowIDText;
Cursor c;
String name;
String category;
String description;
//final String SQL_STATEMENT = "SELECT Recipe_Name, Recipe_Category, Recipe_Description FROM RecipeData WHERE _id = " + RowIDText ;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.create); // sets the content view to main
EditRecipe = (EditText) findViewById(R.id.editText1);
EditRecipe2 = (EditText) findViewById(R.id.editText2);
EditRecipe3 = (EditText) findViewById(R.id.editText3);
RowIDText = (TextView) findViewById(R.id.RowID);
Rname = (Button) findViewById(R.id.RecipeName);
String RowID;
try{
Bundle extras = getIntent().getExtras();
if (extras != null) {
RowID = extras.getString("SELECTED");
RowIDText.setText(RowID);
}
if (RowIDText != null){
entry = new CBDataBaseHelper(this);
String s = RowIDText.getText().toString();
int ID = Integer.parseInt(s);
entry.open();
Cursor cursor = entry.fetchRow(ID);
if (cursor.moveToFirst()){ // data?
name = cursor.getString(cursor.getColumnIndex(CBDataBaseHelper.KEY_NAME));
}
entry.close();
EditRecipe.setText(name);
EditRecipe2.setText(category);
EditRecipe3.setText(description);
}
}catch (Exception e){
String error = e.toString();
Dialog d = new Dialog(this);
d.setTitle("darn");
TextView tv = new TextView(this);
tv.setText(name);
d.setContentView(tv);
d.show();
}
}
public void doIt(View view) {
String Name = EditRecipe.getText().toString();
String description = EditRecipe.getText().toString();
String category = EditRecipe.getText().toString();
entry = new CBDataBaseHelper(CBCreate.this);
entry.open();
entry.createEntry(Name, description, category);
entry.close();
EditRecipe.setText("");
EditRecipe2.setText("");
EditRecipe3.setText("");
}
public void goBack(View view){
Intent myIntent = new Intent(this, CBFilter.class);
startActivity(myIntent);
}
}
and then this is what i have within the database helper class... i think i want to call this method?
public Cursor fetchRow(long rowId) throws SQLException {
Cursor mCursor = mydatabase.query(true, DATABASE_TABLE, new String[] { KEY_ROWID,
KEY_CATEGORY, KEY_DESCRIPTION }, KEY_ROWID + "="
+ rowId, null, null, null, null, null);
if (mCursor != null) {
mCursor.moveToFirst();
}
return mCursor;
}

I would use mydatabase.rawquery(QUERY) instead of the cursors query method. Its easier for SQL developers I think. Anyways, once you have your values in the cursor, you can do this
EditRecipe.setText(cursor.getString(0));
EditRecipe2.setText(cursor.getString(1));
Where 0 represents the first column in your returned table. You would put that code after your mCursor.moveToFirst();

How to retrieve data from database in android Creating database on SqliteBrowser

I have jokes.db database. This database file imported from using this article., http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/. Now i have Jokes.db in to /data/data/a.b.c/database/Jokes.db. In this database , I have two table NepaliJokes and EnglishJokes. So Now I want to retrive this nepali and english jokes and display in to textview, But I have done following code but couldnot more idea behind How to retrieve data from database.
public class FunnyJokes extends Activity implements View.OnClickListener {
private SQLiteDatabase database;
#Override
protected void onCreate(Bundle savedInstanceState) {
Button back;
super.onCreate(savedInstanceState);
setContentView(R.layout.displayjoks1);
back = (Button) findViewById(R.id.back_btn);
back.setOnClickListener(this);
DataBaseHelper helper = new DataBaseHelper(this);
database = helper.getWritableDatabase();
loadJokes();
}
private void loadJokes() {
//jok=new ArrayList<String>();
/*Cursor c = database.query("SELECT title,body" +
" FROM " + 'tableName'
+ " WHERE category=1;",
null);*/
Cursor c = database.query("NepaliJokes",
null, null, null, null, null, null);
c.moveToPosition(0);
TextView tv= (TextView) findViewById(R.id.textView1);
tv.append(c.getString(1));
c.close();
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.back_btn:
FunnyJokes.this.finish();
break;
default:
break;
}
}
}
I also use the database file import from in DDMS->fileExploer. I import database file Pull mobile icon from left of file explorer section.

To read values from the table:
Create a cursor to read data from the database.
Write the following function.
public Cursor retrieveRecords(int category)
{
Cursor c = null;
c = db.rawQuery("select title,body from tablename where category=" +category, null);
return c;
}
Now get the values from the cursor.
public void getDataFromDatabase()
{
try
{
Cursor cursor = null;
db.OpenDatabase();
cursor = db.retrieveRecords();
if (cursor.getCount() != 0)
{
if (cursor.moveToFirst())
{
do
{
titleArrayList.add(cursor.getString(cursor.getColumnIndex("title")));
bodyArrayList.add(cursor.getString(cursor.getColumnIndex("body")));
} while (cursor.moveToNext());
}
db.closeDatabase();
}
cursor.close();
}
catch(Exception e)
{
e.printStackTrace();
}
}

I have two table and apply all the query insert update delete and createtable select using the code it is working fine.
I hope this is help.

First of all don't use tv.append instead use setText because if u use append then ur next joke will be append to the previous one and textView show the jokes as you click the button
Actually the answere is long enough so
I have written a ansere in my blog please see the link the code will do exactly what you are lokking for but i just made one table you can add more table similarly.
