Assuming R.layout.dialog_layout is a layout with recyclerview

Dialog dialog = new Dialog(context, R.style.DialogSlideAnim);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
dialog.setContentView(R.layout.dialog_layout);
dialog.setCanceledOnTouchOutside(true);
dialog.setCancelable(true);
dialog.show();

RecyclerView rvTest = (RecyclerView) dialog.findViewById(R.id.rvTest);
rvTest.setHasFixedSize(true);
rvTest.setLayoutManager(new LinearLayoutManager(context));
rvTest.addItemDecoration(new SimpleDividerItemDecoration(context, R.drawable.divider));

DataDialogAdapter rvAdapter = new DataDialogAdapter(context, rvTestList);
rvTest.setAdapter(rvAdapter);

styles.xml

<style name="DialogSlideAnim" parent="@android:style/Theme.Dialog">
    <item name="android:windowAnimationStyle">@style/DialogAnimation</item>
</style>
<style name="DialogAnimation">
    <item name="android:windowEnterAnimation">@anim/slide_up_dialog</item>
    <item name="android:windowExitAnimation">@anim/slide_down_dialog</item>
</style>
