mrecyclerview.setClickable(true);
mrecyclerview.setEnabled(true);
mrecyclerview.setForeground(null);

回答1:
You can add a simple boolean to your adapter like this:
public boolean isClickable = true;
and set it in your fab-click:
mAdapter.isClickable = true/false;
And within your OnClickListener in the Adapter, only act when it is clickable:
public void onClick(View view) {
if(!isClickable)
return;
// do your click stuff
}

To disable RecyclerView, follow below steps:
1. Add following view into your layout file,
<View
android:id="@+id/viewDisableLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#40000000"
android:clickable="true"
android:focusable="true"
android:visibility="gone"/>
2. Set View Visibility `View.VISIBLE when you want to disable RecyclerView else
回答3:
You can simply use recursion to disable/enable clicks on view
public static void setClickable(View view, boolean clickable) {
if (view != null) {
if (view instanceof ViewGroup) {
ViewGroup viewGroup = (ViewGroup) view;
for (int i = 0; i < viewGroup.getChildCount(); i++) {
setClickable(viewGroup.getChildAt(i), clickable);
}
}
view.setClickable(clickable);
}
}

You need to set the click listener to every FloatingActionButton.
see this issue on library

Björn Kechel's answer helps me. As he said I just added Boolean. When i click the fab menu the boolean is activated. Then have to write the condition on mrecyclerview.addOnItemTouchListener
Java Class
public Boolean fabClick = false;
floatMenu.setOnMenuToggleListener(new FloatingActionMenu.OnMenuToggleListener() {
@Override
public void onMenuToggle(boolean opened) {
if (opened) {
final int color = R.color.transp;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
fabClick = true;
mrecyclerview.setClickable(false);
mrecyclerview.setEnabled(false);
mrecyclerview.setForeground(new ColorDrawable(ContextCompat.getColor(getContext(), color)));
}
} else {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
fabClick = false;
mrecyclerview.setClickable(true);
mrecyclerview.setEnabled(true);
mrecyclerview.setForeground(null);
}
}
}
});
mrecyclerview.addOnItemTouchListener(new RecyclerTouchListener(getActivity(), mrecyclerview, new RecyclerTouchListener.ClickListener() {
@Override
public void onClick(View view, int position) {
if(!fabClick) {
android.support.v4.app.FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.fragment_anim_start, R.anim.fragment_anim_stop);
Intent i = new Intent(getActivity(), Group_Chat_Screen.class);
startActivity(i);
}
}

Working solution with RecyclerView.OnItemTouchListener:
@SuppressLint("ClickableViewAccessibility")
@BindingAdapter("itemsClickable")
fun setRecyclerViewClickable(view: RecyclerView, clickable: Boolean) {
view.isEnabled = clickable
if (!clickable) {
val itemTouchListener = object : RecyclerView.OnItemTouchListener {
override fun onTouchEvent(rv: RecyclerView?, e: MotionEvent?) {
}
override fun onInterceptTouchEvent(rv: RecyclerView?, e: MotionEvent?): Boolean {
return rv?.isEnabled == false
}
override fun onRequestDisallowInterceptTouchEvent(disallowIntercept: Boolean) {
}
}
view.addOnItemTouchListener(itemTouchListener)
view.tag = itemTouchListener
} else {
(view.tag as? RecyclerView.OnItemTouchListener)?.let {
view.requestDisallowInterceptTouchEvent(true)
view.removeOnItemTouchListener(it)
}
}
}
回答7:
You can disable the touch of recyclerview
recyclerView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
return true;
}
});
回答8:
In the xml file, set the layout_width and layout_height for FloatingActionMenu as match_parent and set clickable as false :
android:layout_width="match_parent " android:layout_height="match_parent " android:clickable="false"In your java class,
floatMenu.setOnMenuToggleListener(new FloatingActionMenu.OnMenuToggleListener() { @Override public void onMenuToggle(boolean opened) { if (opened) { floatMenu.setClickable(true); } else { floatMenu.setClickable(false); } } });
This should work.
