Android 如何在对话框中调用setAction？

我想创建添加数据到SQL lite与弹出对话框，在对话框中只有一个文本编辑和按钮保存。在Snackbar中，通常使用setAction（）。但在对话中，我不知道如何调用“AddData”

我想调用这段代码AddData to onCreate，这段代码将文本保存在sqlLite中

public View.OnClickListener AddData = new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            View customLayoutView = View.inflate(getActivity(), R.layout.layout_add_category_expanses, null);
            final EditText edNim = customLayoutView.findViewById(R.id.inputcategoryexpanses);
            final AlertDialog.Builder builder;
            builder = new AlertDialog.Builder(getActivity());
            builder.setCancelable(true);
            builder.setTitle(R.string.strTitleAlert);
            builder.setView(customLayoutView);
            builder.setPositiveButton(R.string.btnKlikstr, new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    String nim = edNim.getText().toString();
                    if (databaseHelper.addCategoryExpanses(new CategoryExpanses(nim))) {
                        getDataFromSQLite();
                        Toast.makeText(getActivity(), "Data berhasil disimpan", Toast.LENGTH_LONG).show();
                    } else {
                        Toast.makeText(getActivity(), "Data gagal disimpan", Toast.LENGTH_LONG).show();
                    }
                    dialogInterface.dismiss();
                }
            });
            AlertDialog alertDialog = builder.create();
            alertDialog.show();
        }
    };

请帮我解决这个问题。谢谢。

你必须做一些类似的事情：

 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.list_category_expanses, container, false);

    mTextMessage = (TextView) view.findViewById(R.id.message);

    textSubcategoryExpanses = (AppCompatTextView) view.findViewById(R.id.textSubcategoryExpanses);
    recyclerViewCategoryExpanses = (RecyclerView) view.findViewById(R.id.recyclerViewCategoryExpanses);

    Button btn1 = view.findViewById(R.id.buttonListCategoryExpanses);
    btn1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            View customLayoutView = View.inflate(getActivity(), R.layout.layout_add_category_expanses, null);
            final EditText edNim = customLayoutView.findViewById(R.id.inputcategoryexpanses);
            final AlertDialog.Builder builder;
            builder = new AlertDialog.Builder(getActivity());
            builder.setCancelable(true);
            builder.setTitle(R.string.strTitleAlert);
            builder.setView(customLayoutView);
            builder.setPositiveButton(R.string.btnKlikstr, new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    String nim = edNim.getText().toString();
                    if (databaseHelper.addCategoryExpanses(new CategoryExpanses(nim))) {
                        getDataFromSQLite();
                        Toast.makeText(getActivity(), "Data berhasil disimpan", Toast.LENGTH_LONG).show();
                    } else {
                        Toast.makeText(getActivity(), "Data gagal disimpan", Toast.LENGTH_LONG).show();
                    }
                    dialogInterface.dismiss();
                }
            });
            AlertDialog alertDialog = builder.create();
            alertDialog.show();

        }
    });
    initObjects();
    return view;
}
