BotomSheetDialog FabButton Anchor View funktioniert nicht wie erwartet
Hi Ich versuche, die Fab-Schaltfläche in BottomSheetDialog zu verankern, aber es funktioniert nicht. EDITED Hier ist mein Dialog
public static class QuickInfoDialog extends BottomSheetDialogFragment {
private BottomSheetBehavior.BottomSheetCallback mBottomSheetBehaviorCallback = new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
if (newState == BottomSheetBehavior.STATE_HIDDEN) {
dismiss();
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
}
};
@Override
public void onStart() {
super.onStart();
// Less dimmed background; see https://stackoverflow.com/q/13822842/56285
Window window = getDialog().getWindow();
WindowManager.LayoutParams params = window.getAttributes();
params.dimAmount = 0.0f; // dim only a little bit
window.setAttributes(params);
// Transparent background; see https://stackoverflow.com/q/15007272/56285
// (Needed to make dialog's alpha shadow look good)
window.setBackgroundDrawableResource(android.R.color.transparent);
}
@Override
public void setupDialog(Dialog dialog, int style) {
super.setupDialog(dialog, style);
View contentView = View.inflate(getContext(), R.layout.location_info_sheet, null);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
dialog.setContentView(contentView);
CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) ((View) contentView.getParent()).getLayoutParams();
CoordinatorLayout.Behavior behavior = params.getBehavior();
if (behavior != null && behavior instanceof BottomSheetBehavior) {
, ((BottomSheetBehavior) behavior).setBottomSheetCallback(mBottomSheetBehaviorCallback);
}
// FloatingActionButton navBtn = (FloatingActionButton) dialog.findViewById(R.id.btn_fab_direction);
// FrameLayout.LayoutParams layoutParams = (FrameLayout.LayoutParams) navBtn.getLayoutParams();
// int boundary = (int) (layoutParams.topMargin + (layoutParams.width * 0.5));
// layoutParams.topMargin = boundary;
// LogUtils.LOGD(TAG, "boundary: " + boundary);
// navBtn.setLayoutParams(layoutParams);
}
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
}
Dies ist meine XML-Datei, in der meine anderen Layouts und die Fab-Schaltfläche definiert sind.
