Are you intending to use Java (and write a native app) or use a cross-platform tool such as Xamarin?
If you are opting for the latter then read my introductory article Introduction to Xamarin.Android[^]

this is my dialog
@Override
protected Dialog onCreateDialog(int id, Bundle args){
switch(id){
case 1:
return new AlertDialog.Builder(this)
.setIcon(R.drawable.ic_launcher)
.setTitle("Pick some")
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int whichButton)
{
}
})
.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int whichButton)
{
}
})
.setMultiChoiceItems(items, itemsChecked, new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog, int which,boolean isChecked) {
}
}
)
.create();

I just wrote what I tried. May have been wrong and that is not the way, that's why I turned to for help

OK, but you have an error message telling you what you have done wrong. You need to fix that before you can proceed.

I tried a few things but still not working
I have been really desperate, do not know how to solve it

Have you corrected the coding error that I pointed out to you? Or do you have some new problem?

Hi there,
I have extracted the json data, but now I need to set those values in options menu as menuitems. Please kindly help!
SubMenu submenu = menu.addSubMenu("Select");
submenu.add(a1);
submenu.add(a2);
submenu.add(a3);
submenu.add(a4);
submenu.add(a5);
The above code I used to add the values in options menu with onOptionsCreateMenu method. a1,a2,a3,a4,a5 are not strings those are extracted and stored in string so just I m added them but failed..!

The code for how I extracted from json:
if((jsonarray.get(0).toString()) != null){
JSONObject jsonobj = new JSONObject(jsonarray.get(0).toString());
Log.e("aptlist", jsonobj.toString());
JSONArray array1= jsonobj.getJSONArray(TAG_APTLIST);
String a1= array1.get(0).toString();
String a2= array1.get(1).toString();
String a3= array1.get(2).toString();
String a4= array1.get(3).toString();
String a5= array1.get(4).toString();
}
Now I want those a1,a2,a3,a4,a5 values in optionsmenu when I click.
I tried as below,but got error as NullPointException
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
getMenuInflater().inflate(R.menu.main, menu);
SubMenu submenu = menu.addSubMenu("Select Apartment");
submenu.add(a1);
Log.e("msg from a1", a1.toString());
submenu.add(a2);
submenu.add(a3);
submenu.add(a4);
submenu.add(a5);
return true;
}
