Question

我已成功实施材料对话框：

现在，当我在“材料对话框”中进行选择时，我想在片段抽屉中更新标签。所以我想：简单，只需实现接口，你就会有回调方法。但这些方法从未运行过。

我尝试了一些方法，但它们都不起作用，因为它们永远不会运行。

 public class FragmentDrawer extends Fragment implements MaterialDialog.ListCallbackSingleChoice, MaterialListPreference.OnPreferenceClickListener, MaterialDialog.OnShowListener, MaterialDialog.OnClickListener{
(...)
      @Override
        public boolean onSelection(MaterialDialog materialDialog, View view, int i, CharSequence charSequence) {
            SnackbarManager.show(
                    Snackbar.with(getActivity())
                            .text("Single-line snackbar"));
            return false;
        }
}

对话：

new MaterialDialog.Builder(getActivity())
                                                    .title(R.string.title)
                                                    .items(R.array.items)
                                                    .itemsCallbackSingleChoice(-1, new MaterialDialog.ListCallbackSingleChoice() {
                                                        @Override
                                                        public boolean onSelection(MaterialDialog dialog, View view, int which, CharSequence text) {
                                                            /**
                                                             * If you use alwaysCallSingleChoiceCallback(), which is discussed below,
                                                             * returning false here won't allow the newly selected radio button to actually be selected.
                                                             **/
                                                            return true;
                                                        }
                                                    })
                                                    .positiveText(R.string.positive_text)
                                                    .showListener(new DialogInterface.OnShowListener() {
                                                        @Override
                                                        public void onShow(DialogInterface dialog) {
                                                        }
                                                    })
                                                    .show();

你尝试过这个吗？：

public class FragmentDrawer extends Fragment implements MaterialDialog.ListCallbackSingleChoice, MaterialListPreference.OnPreferenceClickListener, MaterialDialog.OnShowListener, MaterialDialog.OnClickListener{
(...)
      @Override
        public boolean onSelection(MaterialDialog materialDialog, View view, int i, CharSequence charSequence) {
            SnackbarManager.show(
                    Snackbar.with(getActivity())
                            .text("Single-line snackbar"));
            return false;
        }
}


new MaterialDialog.Builder(getActivity())
                                                    .title(R.string.title)
                                                    .items(R.array.items)
                                                    .itemsCallback(this)
                                                    .positiveText(R.string.positive_text)
                                                    .showListener(new DialogInterface.OnShowListener() {
                                                        @Override
                                                        public void onShow(DialogInterface dialog) {
                                                        }
                                                    })
                                                    .show();
