Question

I’m trying to make it so that a dialog pops up for users which has two buttons in the body and a cancel button at the bottom. When a user clicks one of the two buttons the dialog will disappear, and hitting cancel will just cancel out of the dialog. The cancel part works fine, but I can’t figure out how to dismiss the dialog manually. Here’s my code:

public void onItemClick(AdapterView<?> parent, View view,
                    final int position, long id) {

                Context mContext = getApplicationContext();
                LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
                View layout = inflater.inflate(R.layout.config_dialog,
                        (ViewGroup) findViewById(R.id.config_dialog));

                Button connect = (Button) layout.findViewById(R.id.config_connect);
                Button delete = (Button) layout.findViewById(R.id.config_delete);

                alert = new AlertDialog.Builder(Configuration.this);
                alert.setTitle("Profile");

                connect.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {

                        trace("Connect" + Integer.toString(position));
                        toast("Connected");
                        SharedPreferences app_preferences = 
                                PreferenceManager.getDefaultSharedPreferences(Configuration.this);
                        SharedPreferences.Editor editor = app_preferences.edit();
                        editor.putString("IP", fetch.get(position).IP);
                        editor.commit();
                        //Add dismiss here


                    }

                });

                delete.setOnClickListener(new View.OnClickListener() {

                    public void onClick(View v) {

                        trace("Delete");

                    }

                });


                // Set layout 
                alert.setView(layout);

                alert.setNegativeButton("Close", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int whichButton) {
                        // Canceled.
                    }
                });

                alert.show();

When I try to add the alert.dismiss(), Eclipse gives me an error. .dismiss() also doesn’t show up in alert’s autocomplete list.

AlertDialog.Builder is best suited for small simple dialog boxes rather than custom dialogs.

The cleanest way to handle custom dialogs is to subclass AlertDialog as a private static class in your context (in this case your activity).

Here is a simplified example:

public class AlertDialogTestActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        AlertDialog alert = new myCustomAlertDialog(this);
        alert.show();

    }

    private static class myCustomAlertDialog extends AlertDialog {

        protected myCustomAlertDialog(Context context) {
            super(context);

            setTitle("Profile");

            Button connect = new Button(getContext());
            setView(connect);
            connect.setText("Don't push me");
            connect.setOnClickListener(new View.OnClickListener() {

                public void onClick(View v) {
                    // I want the dialog to close at this point
                    dismiss();
                }
            });
        }

    }
}
