其中用到的资源文件 dialog_recycler_view.xml

使用

RecyclerView recyclerView = new RecyclerView(this);    recyclerView.setLayoutManager(new LinearLayoutManager(this));    recyclerView.setHasFixedSize(true);    recyclerView.setAdapter(homeAdapter);    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,            homeAdapter.getItemCount() * Utils.getHeightInPx(this)/12);    new IOSRecyclerViewDialog(this).builder()            .setCancelable(false)            .setCanceledOnTouchOutside(false)            .setCustomView(recyclerView, lp)            .setTitle(selectedBrand.getName())            .setPositiveButton(getString(R.string.add_attention), v ->                            presenter.saveData()            ).setNegativeButton(getString(R.string.cancle), v -> {                presenter.getSelectedData().clear();                presenter.getSelectedData().addAll(originalAllSelected);                presenter.saveData();            })            .show();
