将EditText中的文本控制到AlertDialog中

Question

I try to check the insert text from user into AlertDialog with this:

builder.setPositiveButton(
                getString(R.string.search_button),
                new DialogInterface.OnClickListener() {
                    public void onClick(
                            DialogInterface dialog,
                            int id) {


                        mNome = editext.getText().toString();
                        mCognome = editext1.getText().toString();

                        View focusView = null;



                        if (TextUtils.isEmpty(mNome) && TextUtils.isEmpty(mCognome)) {
                            editext.setError(getString(R.string.error_field_required));
                            focusView = editext;
                            cancel=true;
                            focusView.requestFocus();

                        }
                        else{
                        dialog.dismiss();

                        go();}

                    }
                });

        mAlertDialog = builder.create();
        mAlertDialog.show();

But not work, the if the text is empty the AlertDialog disappears

Answer 1

Use this

                 edittext.requestFocus();
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

Answer 2

I had the same problem, so check your String like this :

if(Your_String == null) or if(Your_String.isEmpty())

Hope it will work.
