如何使BottomSheetBehavior片段在内部单击时不会折叠,还需要执行其他操作,例如在单击时折叠键盘才能启用。我一直在为此问题上苦苦挣扎,所以这就是我在StackOverflow上创建此帐户的原因:)

编辑:这是FragmentTwo的FragmentOne容器内的FrameLayout

<FrameLayout
         android:id="@+id/fragment_two_container"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         app:behavior_peekHeight="0dp"
         app:layout_behavior="android.support.design.widget.BottomSheetBehavior" />

现在,在FragmentOne.java内部:

private BottomSheetBehavior bottomSheetBehavior;
private FrameLayout fragmentTwoContainer;
private FragmentTransaction fragmentTransaction;


fragmentTwoContainer = fragmentOneView.findViewById(R.id.fragment_two_container); 
bottomSheetBehavior = BottomSheetBehavior.from(fragmentTwoContainer);

private void startFragmentTwo(){
        bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
        FragmentTwo fragmentTwo = new FragmentTwo();
        fragmentTransaction = getActivity().getSupportFragmentManager().beginTransaction();
        fragmentTransaction.replace(R.id.fragment_two_container, fragmentTwo, "");
        fragmentTransaction.commit();
    }

fragment_two_layout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:id="@+id/fragment_two_linear_layout"
    android:clickable="true"
    android:focusable="true">

<android.support.design.widget.TextInputEditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content" />

</LinearLayout>

FragmentTwo.java

private LinearLayout fragmentTwoLinearLayout;

 fragmentTwoLinearLayout = fragmentTwoView.findViewById(R.id.fragment_two_linear_layout);

private void initListeners(){
        fragmentTwoLinearLayout.setOnClickListener(this);
    }

@Override
public void onClick(View view) {
    switch (view.getId()){
        case R.id.fragment_two_linear_layout:
            Log.i("CLICKED","CLICKED");
            if (getActivity() != null) {
                InputMethodManager inputManager =
                        (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);

                if (inputManager != null) {
                    View v = getActivity().getCurrentFocus();
                    if (v != null) {
                        inputManager.hideSoftInputFromWindow(
                                v.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
                    }
                }
            }
            break;
    }
}

因此,当我在fragmentTwoLinearLayout中单击时,不会打印“ CLICKED”,并且键盘也不会折叠,但是FragmentTwo折叠了。我在FragmentOne.java中尝试了此方法,但实际上并没有用:

bottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState) {
            if(newState == BottomSheetBehavior.STATE_EXPANDED){

                bottomSheet.setOnTouchListener(new View.OnTouchListener() {
                    @Override
                    public boolean onTouch(View view, MotionEvent motionEvent) {
                        return false;
                    }
                });
            }
        }

        @Override
        public void onSlide(@NonNull View bottomSheet, float slideOffset) {

            bottomSheet.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View view, MotionEvent motionEvent) {
                    return false;
                }
            });
        }
    });
