我正在尝试使用BottomSheetFragment实现BottomSheet,当用户在对话框外单击时,该折叠会折叠。我尝试覆盖onCancel
,但是将状态设置为STATE_COLLAPSED
,但是它不起作用-当在外部单击时,BottomSheet消失了。也有setHideable(false)
。因此,我希望当用户在外部单击时, Bottom Sheet 会崩溃,事实并非如此。我该如何实现?
public class MyBottomSheet extends BottomSheetDialogFragment {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.eazyotp_auto_capture_bottomsheet, container, false);
}
@Override
public void onCancel(@NonNull DialogInterface dialog) {
super.onCancel(dialog);
behavior.setState(BottomSheetBehavior.STATE_COLLAPSED); // does not work
}
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
behavior = getDialog().getBehavior();
behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
behavior.setHideable(false);
behavior.setPeekHeight(70);
// following works well - even when user drags the bottomsheet it gets into collapsed state.
imageView.setOnClickListener(v -> {
if(behavior.getState() == BottomSheetBehavior.STATE_EXPANDED)
behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
else
behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
});
}
}
另外,当我做
setCancelable(false)
时,我不能对imageView
使用折叠/展开 最佳答案
将此添加到activityCreted getDialog().setCanceledOnTouchOutside(true)
关于android - 在BottomSheetFragment中将onCancel重写为setState为COLLAPSED,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/60574613/
