Delete selected item in listview and sqllite database and modify the selected item

My app gets name and address and type (sitdown,take away,phone order) of a restaurant and adds it to a sqlite and then to a listview.
I'm trying to have a delete option when one of the items of the listview get long pressed but I don't know how can I do it and I wanted to have edit option after the row item is generated so I create a context menu for long press and a remove and edit option and if the user selects the edit option a dialog pops up and there is edit texts and radiogroup so the user can modify the selected item
I'm new to android.

any help would be appreciated

first you should create your method for update and delete in your RestaurantHelper.java.
This example of updating an item.
public boolean UpdateData(String name, String address, String type, String note) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(YOUR_COLUMN_NAME, name);
contentValues.put(YOUR_COLUMN_ADDRESS, address);
contentValues.put(YOUR_COLUMN_TYPE, type);
contentValues.put(YOUR_COLUMN_NOTE, note);
db.update(YOUR_TABLE, contentValues, "name= ? AND address = ?", new String[] { name, address } ); // update the item WHERE name = 'name' and address = 'address'
return true;
}
Then create also the method for deleting.
public Cursor deleteData(String your_uniqure_id) {
SQLiteDatabase db = this.getReadableDatabase();
db.execSQL("DELETE FROM your_table WHERE _id = " + your_uniqure_id);
return null;
}
call this method whenever you want.

Clicking on EditText does absolutely nothing and cursor stays at end

How do I get it to open up the keyboard on click and change the cursor position when the user clicks within the text? I'm sure it's something simple, but I've tried setting focusable and focusableInTouchMode to true, enabled, textIsSelectable, and nothing has worked. Have also tried using the following in my code:
InputMethodManager im = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
im.showSoftInput(typeField, 0);

My activity extends AppCompatActivity, if that's important.
Once I click the back button to make the keyboard disappear, I can't make it reappear when I click inside the EditText. Another thing I can't do is move the cursor when I tap inside a String I've already written so if I messed up somewhere, I have to delete text and retype. It's just so frustrating because I have an EditText in another file that works fine and I didn't have to do anything special. The keyboard is opened when I first enter the activity, which is great.
I'm fairly new to Android development so please put things in simple terms, if possible. Thank you so much!

Try this code it may help you solve your problem...

public ArrayList<String> getAllLabels() {

+ DatabaseOpenHelper.TABLE_NAME, null);
ArrayList<String> result = new ArrayList<String>();
if(mcursor!=null)
{
//move cursor to first result record
mcursor.moveToFirst();
do {
result.add(mcursor.getString(mcursor.getColumnIndex("name")));

for fetch data use like that
public Cursor getdata()
{
Log.v(TAG + ".getdata", "getdatamethod called");
Cursor mCursor = null;
openAsWrite();
mCursor=db.query(tablenam,
new String[] {"column name"},null, null, null, null, null);

You haven't called the show() method for your dialog.
Add d1.show() at the end of your onCreate() method

Cannot read EditText in fragment class

I have two tabs and each tab is a Fragment. In one of the fragments (Afragment.claas) I have a dialog box to insert some data, and I want to save them in a database. When I fill the text fields and press OK, the application stops.

This is the code I use for declaring buttons in Fragments - maybe it can help you.
What I would do is access the inflated layout and then you should be able to access items underneath it. Let me know if that makes sense.
LinearLayout theLayout = (LinearLayout)inflater.inflate(R.layout.tab_frag1_layout, container, false);
// Register for the Button.OnClick event
Button b = (Button)theLayout.findViewById(R.id.frag1_button);
#Override
public void onClick(View v) {
Toast.makeText(Tab1Fragment.this.getActivity(), "OnClickMe button clicked", Toast.LENGTH_LONG).show();
}
});
return theLayout;
So maybe you should try this since you inflate your View as "addView"
name = (EditText) addView.findViewById(R.id.etProviderName);

The findViewById should not be called by the activity but by the enclosing view. You should have something like:
In the class
View aView;
In the method:
LayoutInflater inflater = getActivity().getLayoutInflater();
aView = inflater.inflate(R.layout.add_provider, null);
...
EditText name = (EditText) aView.findViewById(R.id.etProviderName);
I hope it helps.
