  public void Show_Dialog() {
        final AlertDialog.Builder alertDialog = new AlertDialog.Builder(
                SwipeActivity.this);
        LayoutInflater inflater = this.getLayoutInflater();
        final View layout = inflater.inflate(R.layout.add_albom_dialog, null);
        alertDialog.setView(layout);

        final InputMethodManager inputManager = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
        //android:digits="abcdefghijklmnopqrstuvwxyz1234567890 "

        alertDialog.setPositiveButton("Create",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        EditText txts = (EditText) layout
                                .findViewById(R.id.addAblum_edit);
                        hideSoftKeyboardDialogDismiss(SwipeActivity.this);
                        if(txts.getText().toString().trim().length() > 0) {
                            Add_album(txts.getText().toString());

                        } else {

                            AlertDialog alertDialog = new AlertDialog.Builder(SwipeActivity.this).create();
                            alertDialog.setTitle("Error");

                                            inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
                                            inputManager.hideSoftInputFromInputMethod(getCurrentFocus().getWindowToken(), 0);

                                        }
                                    });
                            alertDialog.show();

                        }
                        dialog.cancel(); // Your custom code
                    }
                });

        /* When negative (No/cancel) button is clicked */
        alertDialog.setNegativeButton("Cancel",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        hideSoftKeyboardDialogDismiss(SwipeActivity.this);
                        dialog.cancel();
                        //  finish();

                    }

                });
        alertDialog.show();
    }

尝试这个：

protected void hideSoftKeyboard(EditText mSearchView) {
    InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    mgr.hideSoftInputFromWindow(mSearchView.getWindowToken(), 0);
}
