I have a database with for Columns {id,eng,kurd,ar} and I have populated a listview from it that shows only {eng} from the databse. I want to pass the {eng,kurd,ar} which have the same {id} when the user clicks an item in the listview, but when I click an item my app crashes, but everything else works fine there is no error in non of the other classes[adapter,sqliteopenhelper]

I want to pass the Bundle to Result.class
The best approach to passing data from activity to activity and particularly from your database is to pass an (id) as an intent extra then when you arrive at the destination activity, extract it and use it to query your database based on that id.
This will reduce the amount of data you will have to pass through your intent instance.
If you only want to pass 3 items however, you can use intent extras instead of a Bundle like this:
Intent intent = new Intent(MainActivity.this, Result.class);
intent.putExtra("eng",engRes);
intent.putExtra"kurd",kurdRes);
intent.putExtra("ar",arRes);
startActivity(intent);
To extract this in your Results activity;
Intent intent = getIntent();
String enG = intent.getExtras().getString("eng");
String kurD = intent.getExtras().getString("kurd");
String aR = intent.getExtras().getString("ar");
I hope this helps and good luck!

Use android:inputType="number" in EditText to make sure that the input is a number not a string or a charater like this
<EditText
.
.
.
android:inputType="number"
/>
Another solution:
Check if it is a number programmatically
boolean digitsOnly = TextUtils.isDigitsOnly(editText.getText());
Read this article. You will know how to use the logcat
https://guides.codepath.com/android/Debugging-Exceptions-within-your-App
I solve this problem
int code2 = Integer.parseInt(code);
this c2.getString(1) could not Int its give me String
I am using built in list view to display data from the database in a list format,which displays name and contact number in the same line.I want to modify the names or numbers .So how can I get both name and number separately in a custom list view and displayed in some other text fields.

I got an activity that is called from main activity. In the activity, i got database connections established and i fill a spinner according to db data. When a user selects one of the spinner items and press the button, the activity finishes and returns a value to the main activity (activity on result). But the button in the activity doesnt work, so the activity never returns a value to main activity. Here is the code:
import java.io.Serializable;

public class mySpinnerClass extends Activity implements
OnItemSelectedListener {
private VeriTabani veritabani;

Spinner spinner;
Button btnAdd;
String dataBaseName;
int selectedValue;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.spinner);
dataBaseName = "";
selectedValue = -1;
Intent i = getIntent();
dataBaseName = i.getStringExtra("dataBaseName");
veritabani = new VeriTabani(this);
db = veritabani.getWritableDatabase();
// Spinner element
spinner = (Spinner) findViewById(R.id.mySpinner);
// add button
btnAdd = (Button) findViewById(R.id.addButton);
// Spinner click listener
spinner.setOnItemSelectedListener(this);
// Loading spinner data from database
loadSpinnerData();
btnAdd.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
if (dataBaseName == "phoneOrientation") {
Intent intent = getIntent();
intent.putExtra("phoneOrientation", selectedValue);
setResult(RESULT_OK, intent);
finish();
}
else if(dataBaseName== "phonePosition") {
Intent intent = getIntent();
intent.putExtra("phonePosition", selectedValue);
setResult(RESULT_OK, intent);
finish();
}
else if(dataBaseName =="Label"){
Intent intent=getIntent();
intent.putExtra("label",selectedValue);
setResult(RESULT_OK, intent);
finish();
}
}
});
}
private void loadSpinnerData() {
// Spinner Drop down elements
List<String> lables = getAllLabels();
// Creating adapter for spinner
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, lables);
// Drop down layout style - list view with radio button
dataAdapter
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// attaching data adapter to spinner
spinner.setAdapter(dataAdapter);
}
public List<String> getAllLabels() {
List<String> labels = new ArrayList<String>();
// Select All Query
String selectQuery = "SELECT * FROM " + dataBaseName;
Cursor cursor = db.rawQuery(selectQuery, null);
// looping through all rows and adding to list
if (cursor.moveToFirst()) {
do {
labels.add(cursor.getString(cursor.getColumnIndex("isim")));
} while (cursor.moveToNext());
}
// closing connection
// returning lables
return labels;
}
public int returnID(String item) {
int toBereturnedID;
Cursor myCursor = db.rawQuery("SELECT _id from " +dataBaseName+ " WHERE isim="+"'"+item+"'", null);
myCursor.moveToFirst();
toBereturnedID = myCursor.getInt(0);
return toBereturnedID;
}
public void onItemSelected(AdapterView<?> parent, View arg1, int position, long arg3) {
// TODO Auto-generated method stub
String label = parent.getItemAtPosition(position).toString();
selectedValue = returnID(label);
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
You are calling loadSpinnerData(); method in onCreate() of activity so dataBaseName is always going to be empty, so you want to have value of spinner at time click you need to call that with on onClick() method of button, which will give you correct dataBaseName and use dataBaseName.equals("phoneOrientation") instead of dataBaseName == "phoneOrientation"
Try creating a new Intent instead of getIntent().
Intent intent=new Intent();
intent.putExtra("label",selectedValue);
setResult(RESULT_OK, intent);
finish();
Hope it helps.
I newbie in this field.
my application have 6 buttons with different category. when i click on one of the button it will go to another page for displaying listView for particular category in my database.
my problem is, I don't know how do switch case for this method.
Log.d("Reading", "Reading all Kategori ..");
List<UkmLocation> kategori = db.getCategoryFaculty();

results.add(k.getName());

please do help me solve this. thank you
First,pass a query or simply any key value such as department id or department name as an intent with each button click using
intentname.putExtra(keyname_used_to_retrieve_value,value_to_be_passed_to_next_activity);
case R.id.button1:
String query="select * from table_name where something='xyz'";
Intent b1 = new Intent(this, QSResearch.class);
b1.putExtra("myextrakey",query);
startActivity(b1);
Then, receive the intent in the onCreate method of list activity as follows,initialise database and call user defined mylist() and setuplist() functions
Intent i=getIntent();
String x=i.getStringExtra("myextrakey");//this assigns the query to string x
//open database here
mylist();//call myList function which i have defined in the following lines
setUpList();//call setUpList function which i have defined in the following lines
This is the myList function:
private void myList() {
myownlist= new ArrayList<String>();
Cursor myCursor = database.rawQuery(x,null);
myCursor.moveToFirst();
if(!myCursor.isAfterLast()) {
do {
//selects data in column 2 to be displayed on list
String listitem= myCursor.getString(2);
myownlist.add(listitem);
} while (myCursor.moveToNext());
}
myCursor.close();
}
This is the setUpList() function:
private void setUpList() {
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, myownlist));
ListView lv = getListView();
}
I have got the code where through content provider i am retrieving the phone contacts and displaying them in list format.
I want to display the phone no and name of the particular person in next activity when i click on the list format contacts from first activity. I am getting errors in this its not able to perform click operation and display it on to next activity Please help me with this.

I really can't figure out your code at all. The first activity seems to be creating an Intent to start the Full Activity, but it has two "onclick" methods and it does a setResult() and finish() even though it never did getIntent()!
The second activity creates an ACTION_PICK Intent for the entire Phone table, and handles the return by doing a query on the result, which should be the contact ID of the contact whose # the user picked. I don't think it's the entire URI, though; you should verify that through debug. You then try to get the DISPLAY_NAME for this contact.
Fine, but I don't see why you need the first Activity at all.
I posted some instructions on using the Contacts Provider somewhere else on Stackoverflow; just search for android and ContactsContract.
