Alert Dialogue box on image view click listener in android

Question

I am working on android application in which i want to make a selection dialog box on my imageView click listener. Without dialog box it is working fine, but when i add dialog box with list in it it shows exception. My code and error stack is given below:

profileImage.setOnClickListener(new View.OnClickListener() {
               //@Override
               public void onClick(View v) {
                   Toast.makeText(getApplicationContext(), "ImageClicked",
                            Toast.LENGTH_SHORT).show();     

                   final CharSequence[] items = {"Red", "Green", "Blue"};
                   AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());
                   builder.setTitle("Pick a color");
                   builder.setCancelable(false);
                 //  builder.setPositiveButton(R.string.dialog_action_dismiss, null);

                   // creating a single choice item menu (radio buttons list)
                   // -1 indicates that no item should be selected by default
                   // pass index argument starting from 0 to preselect an item if required
                   builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
                     public void onClick(DialogInterface dialog, int item) {
                       Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show();
                     }
                   });

                   AlertDialog alert = builder.create();
                   alert.show();

               }        
            });

thanks for your reply. It works. But it locks my screen, like when i press back button or if i press any point on the screen nothing happens and it will not allow me to go back on the screen. – Usman Khan Nov 25 '14 at 15:18

does it still do this if you use `builder.setCancelable(true);` – petey Nov 25 '14 at 15:21

where you have `builder.setCancelable(false);`, change it to true. – petey Nov 25 '14 at 15:23
