Answer 2

You can try Custom Dialog design u r on Dialog and use it as u wish to use them

final Dialog dialog= new Dialog(context);
dialog.setContentView(R.layout.pre_confirmation_dailog); 
dialog.setTitle("Details...");
dialog.show();

Answer 3

You can try custom dialog as you like

Dialog dialog_help = new Dialog(this);
dialog_help.setContentView(R.layout.title_multi_selectitems_dialog);
EditText et_1 = (EditText) dialog_help.findViewById(R.id.et_help_1);
dialog_help.setCancelable(true);
dialog_help.setTitle("   Help   ");
dialog_help.setCanceledOnTouchOutside(true);
dialog_help.show();
dialog_help.getWindow().setGravity(Gravity.CENTER);
dialog_help.getWindow().setLayout(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);

Answer 4

You can do this very easily.

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);

// set title
alertDialogBuilder.setTitle("Your Title");

// set dialog message
alertDialogBuilder.setMessage("Message here!").setCancelable(false);

// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();

// show it
alertDialog.show();

// After some action
alertDialog.dismiss();

If you have a reference to the AlertDialog somewhere else, you can still call alertDialog.dismiss(). This closes the dialog.

Answer 5

You can also write crocboy's code like this:

AlertDialog alertDialog = new AlertDialog.Builder(context)    
    .setTitle("Your Title")
    .setMessage("Message here!")
    .setCancelable(false)
    .create();

alertDialog.show();

// After some action
alertDialog.dismiss(); 

It does exactly the same thing, it's just more compact.

Answer 6

Really depends on what "action" is being performed:

---

 AlertDialog.Builder dialog_detect= new AlertDialog.Builder(MainActivity.this);
 dialog.setTitle("Detecting.....");
 dialog.setMessage("Please Wait");
 dialog.show();

 timeConsumingDetectMethod();

 dialog.dismiss();

This way you get a frozen UI until timeConsumingDetectMethod() finishes.

---

However, the following way runs the action in background, while a very responsive dialog is shown. Also, cancels the action when dialog is cancelled.

AsyncTask<Void,Void,Void> task = new AsyncTask<Void, Void, Void>() {

        private AlertDialog dialog;

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            dialog= new AlertDialog.Builder(MainActivity.this);
            dialog.setTitle("Detecting.....");
            dialog.setMessage("Please Wait");

            dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
                @Override
                public void onCancel(DialogInterface dialogInterface) {
                    cancel(true);
                }
            });

            dialog.show();
        }

        @Override
        protected Void doInBackground(Void... voids) {
            timeConsumingDetectMethod();
            return null;
        }

        @Override
        protected void onPostExecute(Void aVoid) {
            super.onPostExecute(aVoid);
            dialog.dismiss();
        }

    }.execute();
