如何使BottomSheetDialogFragment出现在BottomNavigationView的顶部以及如何使其出现在BottomNavigationView的下方
我正试图使BottomSheetDialogFragment出现在BottomNavigationView的顶部和BottomNavigationView的下方，即具有较低的高度。 BottomSheetDialogFragment将具有一个类似YouTube的视频播放器，并带有RecyclerView并展开和折叠底部表格。 我已经研究了一些建议，但没有解决。包括Stackoverflow。 按照下面的代码，我尝试了Show（）方法的两个变体-但没有一个起作用。 我可以执行“展开”，“合拢”等动作，不用担心。问题是将BottomSheet放在Activity的BottomNavigationView后面和RecyclerView之上。
代码活动
公共类myController扩展了CommonActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//inflate the layout of the activity
setContentView(R.layout.controller_layout);
//other activity codes
//progressBar = findViewById(R.id.progressBar);
//contains initialization codes for views and recyclerview
//initViews();
}
OPTION 01: It's the CALL that everyone is pointing to BottomSheetDilogFragment, except BottomSheet is over BottomNavigationView
INITIALIZED when clicking on a item (thumbnail) of a RecyclerView in the layout of the activity/fragment
public void initBottomSheet(Bundle b){
VideoViewBottomSheet fragment = new VideoViewBottomSheet();
fragment.setArguments( b );
fragment.show( getSupportFragmentManager(), VideoViewBottomSheet.FRAGMENT_KEY );}
OPTION 02: I tried this option for BottomSheetDilogFragment, in it the BottomSheet is
DOWN of the BottomNavigationView, BUT behave like a NORMAL FRAGMENT and not as BottomSheetDilogFragment, DO NOT EXPAND, DO NOT COLLAPSE, NOTHING.
public void initBottomSheet(Bundle b){
VideoViewBottomSheet fragment = new VideoViewBottomSheet();
fragment.setArguments( b );
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.add(R.id.bottom_sheet_loyout, fragment);
ft.commit();
}
}
CODE BottomSheetFragment
@Override
public void onStart() {
super.onStart();
Dialog dialog = getDialog();
if (dialog != null) {
View view = getView();
final View parent = (View) view.getParent();
final View bottomSheet = dialog.findViewById(R.id.rv_bottom_sheet);
final View videoView = bottomSheet.findViewById(R.id.videoView);
final View bottom_nav_view = getActivity().findViewById(R.id.bottom_nav_view);
final int screenHeight = ViewGroup.LayoutParams.MATCH_PARENT;
final View relativeLayout = getActivity().getWindow().getDecorView().getRootView().findViewById(R.id.relativelayout);
final View coodinatorLayout = getActivity().getWindow().getDecorView().getRootView().findViewById(R.id.coordinatorlayout);
CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) (parent).getLayoutParams();
CoordinatorLayout.Behavior behavior = params.getBehavior();
parent.setFitsSystemWindows(false);
bottomSheet.getLayoutParams().height = screenHeight;
params.gravity = Gravity.TOP | Gravity.CENTER_HORIZONTAL;
final BottomSheetBehavior bottomSheetBehavior = (BottomSheetBehavior) behavior;
bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
if (bottomSheetBehavior instanceof BottomSheetBehavior) {
offsetY = 0;
((BottomSheetBehavior) bottomSheetBehavior).setBottomSheetCallback(
new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
if(slideOffset>0.2 ){
bottomSheetBehavior.setHideable(false);
bottomSheetBehavior.setPeekHeight(bottom_nav_view.getHeight()+56 );
bottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
parent.setPadding(0,0,0,bottom_nav_view.getHeight()+56);
parent.setBackgroundColor(Color.GREEN);
bottom_nav_view.setVisibility(View.VISIBLE);
bottom_nav_view.setBackgroundColor(Color.YELLOW);
}
offsetY = slideOffset;
}
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
}
});
}
}
}
预期结果是类似于Youtube Player的BottoSheet。也就是说，其中包含一个片段RecyclerView和播放视频的BottomSheet。
