我正在使用浮动操作按钮。我想在按 FAB 按钮时禁用 Recyclerview 项目的单击。我尝试了这个方法，但不起作用
setClickable(true);我的布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:fab="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="#fff"
tools:context="com.hartwintech.socialchat.activity.IconTabsActivity">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
>
</android.support.v7.widget.RecyclerView>
<com.github.clans.fab.FloatingActionMenu
android:id="@+id/floatmenu"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginBottom="60dp"
android:layout_marginRight="16dp"
fab:fab_showAnimation="@anim/show_from_bottom"
fab:fab_hideAnimation="@anim/hide_to_bottom"
fab:menu_labels_style="@style/MenuLabelsStyle"
fab:menu_shadowColor="#444"
fab:menu_colorNormal="#FFB805"
fab:menu_colorPressed="#F2AB00"
fab:menu_colorRipple="#D99200"/>
</RelativeLayout>
Java 类
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) {
mrecyclerview.setClickable(false);
mrecyclerview.setEnabled(false);
mrecyclerview.setForeground(new ColorDrawable(ContextCompat.getColor(getContext(), color)));
}
} else {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
mrecyclerview.setClickable(true);
mrecyclerview.setEnabled(true);
mrecyclerview.setForeground(null);
}
}
}
});
您可以向适配器添加一个简单的布尔值，如下所示：
public boolean isClickable = true;
并将其设置在您的 fab 中 - 单击：
mAdapter.isClickable = true/false;
并且在适配器的 OnClickListener 中，仅在可点击时才起作用：
public void onClick(View view) {
if(!isClickable)
return;
// do your click stuff
}
要禁用 RecyclerView，请按照以下步骤操作：
1。将以下视图添加到您的布局文件中，
<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.当你想禁用 RecyclerView 时，设置视图可见性 `View.VISIBLE
您可以简单地使用递归来禁用/启用视图上的点击
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);
}
}
Björn Kechel 的回答对我有帮助。正如他所说，我只是添加了布尔值。当我单击 fab 菜单时，布尔值被激活。然后要把条件写在
mrecyclerview.addOnItemTouchListener 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);
}
}
使用 RecyclerView.OnItemTouchListener 的工作解决方案：
@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)
}
}
}
Java
recyclerView.setOnTouchListener((view1, motionEvent) -> true );科特林
reyclerView.setOnTouchListener { v, event -> true }此解决方案禁用所有触摸事件
您可以禁用recyclerview的触摸
recyclerView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
return true;
}
});
在xml文件中，将FloatingActionMenu的layout_width和layout_height设置为match_parent，并将clickable设置为false：
android:layout_width="match_parent "
android:layout_height="match_parent "
android:clickable="false"
在你的java课程中，
floatMenu.setOnMenuToggleListener(new FloatingActionMenu.OnMenuToggleListener() {
@Override
public void onMenuToggle(boolean opened) {
if (opened) {
floatMenu.setClickable(true);
} else {
floatMenu.setClickable(false);
}
}
});
这应该有效。
我用非常简单的逻辑解决了这个问题。这将防止双击单个项目和
RecyclerView在您的 Activity 中声明一个变量。
private long mLastClickTime = 0;
然后在任何
OnClickListener@Override
public void onClick(View v) {
if(SystemClock.elapsedRealtime() - mLastClickTime < 1000){//You can reclick after 1 second
return;//Before 1 seconds from first click this onclick will return from here
}
mLastClickTime = SystemClock.elapsedRealtime();
//Do stuff here
}
实际上，当我搜索防止双击按钮时，我在 stackover flow 中找到了这个解决方案。我写这行是为了确认实际答案是由某人发布的（不幸的是，我无法找到该答案来链接他/她的答案。）
希望这能解决您的问题。:)
yourRecycelerview.suppresslayout(true)
干净、简单，无需项目触摸侦听器或视图持有者逻辑即可工作。
文档：
/**
* Tells this RecyclerView to suppress all layout and scroll calls until layout
* suppression is disabled with a later call to suppressLayout(false).
* When layout suppression is disabled, a requestLayout() call is sent
* if requestLayout() was attempted while layout was being suppressed.
* <p>
* In addition to the layout suppression {@link #smoothScrollBy(int, int)},
* {@link #scrollBy(int, int)}, {@link #scrollToPosition(int)} and
* {@link #smoothScrollToPosition(int)} are dropped; TouchEvents and GenericMotionEvents are
* dropped; {@link LayoutManager#onFocusSearchFailed(View, int, Recycler, State)} will not be
* called.
*
* <p>
* <code>suppressLayout(true)</code> does not prevent app from directly calling {@link
* LayoutManager#scrollToPosition(int)}, {@link LayoutManager#smoothScrollToPosition(
*RecyclerView, State, int)}.
* <p>
* {@link #setAdapter(Adapter)} and {@link #swapAdapter(Adapter, boolean)} will automatically
* stop suppressing.
* <p>
* Note: Running ItemAnimator is not stopped automatically, it's caller's
* responsibility to call ItemAnimator.end().
*
* @param suppress true to suppress layout and scroll, false to re-enable.
