How to disable behind view click event Framelayout

Question

Here i have one view pager activity which has one imageview and 2 overlay bars. there overlay bars i made using android xml file layout itself.

Here my requirement is like that

1) single tap on view pager's imageview first time = show top and bottom rectangle overlaybar. 2) single tap on view pager's imageview second time = hide these overlays.

These both are functions like android gallary view type.

But here when these top and bottom layout bar displays at that time i want to use only buttons click only which buttons are declare within this layout.

But I am not getting success to achieve this thing.

Problems

1) when top or bottom bar is there if i can click on next or previous button than its takes event for behind imageview single tap touch event, And my bar is getting invisible. 2) Only wants declare buttons event only 3) Avoid imageview getting clicked when i touch to overlay bar.

In short when my top and bottom image bar appears at that time no touh event takes place for imageview from top and bottom image bar. I can click on imageview but not making clickable when i click on actually next or previous or share button.

So these are the problems which i am facing, Please help me .

I know this is 5 years too late, but what I discovered is your homescreen should be a fragment. Don't add controls to 'activity_main' or 'content_main' other than a framelayout to hold fragments. Adding controls to the main activity's layout will cause overlaying fragments to fire events for the main activity's controls when the same coordinates are pressed. Set each fragment's parent layout to 'android:clickable="true"'. – Headset

Answer 2

A better way is to set the top and bottom frame to be clickable, with:

android:clickable="true"

Doing so will make sure that the view/frame itself will trap all clicking events, and will not pass it through the view behind it. Note this method works for all layout/view/controls, but many controls (such as buttons) already have this function on by default.

Refugio

This works only if the lower view is not a button. Otherwise the button is still picking up the click event. – Bedsore

Should be the accepted answer. The current accepted answer is a hack – Percept

Well, doesn't work for me, the listview behind it still gets tapped – Discarnate

To test this if you turn on Accessiblity/Talkback then you would see the items selected on the back of the screen – Justitia

Is there a way to do this programmatically? – Uzial

in this case.. I agree click is trapped... but a ripple effect is shown when we add clickalbe true to a linear or relative layout – Undergird

@Uzial Sure, use view.setClickable(true), see here - developer.android.com/reference/android/view/… – Theoretical

Yes, this solution works fine, but be aware that if you need to implement Talkback mode it will announce the view as clickable. So it might be confusing for some users, who rely on Talkback. – Jury

Answer 3

android:clickable="true" for top and bottom bar.

or give each FrameLayout an onClickListener.

Bobbe

Answer 4

just add this to each of your framelayout view containers so that absorb the click:

  android:clickable="true"
    android:focusable="true"
    android:focusableInTouchMode="true"

Beverleybeverlie

Answer 5

By default, some controls have clickable property as true. But the layout doesn't. For layout, we have to make them explicitly clickable so that it will grab the events of clicks or touches and will not let it pass to background views. This is how we do it:

android:clickable="true"
android:focusable="true"
android:focusableInTouchMode="true"

Add these lines to all your layouts, so that it will grab/absorb events and will not let it pass to background views.

Answer 6

@gordon1hd1 answer is correct but for those who are still confused, I am adding my layout which contains a FrameLayout as parent and a LinearLayout and twoImageViews as childs.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">         
     <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/scroll_parent"
            android:orientation="horizontal" />
    <ImageView
        android:id="@+id/ivArrowLeft"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="4dp"
        android:src="@drawable/actionbar_back"
        android:layout_gravity="left|center_vertical"
        android:background="#3f808080"
        android:clickable="true"
        />
    <ImageView
        android:id="@+id/ivArrowRight"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="4dp"
        android:src="@drawable/actionbar_back"
        android:layout_gravity="right|center_vertical"
        android:background="#3f808080"
        android:rotation="180"
        android:clickable="true"
        />
</FrameLayout>

Previously, the Linearlayout was also intercepting touch events when either of ImageViews were pressed. Adding android:clickable="true" to both ImageViews resolved the issue.

If you are also facing this type of issue, add android:clickable="true" to the view you want to trap the clicking event.

Answer 7

Simply, Set android:clickable="true" in xml to your foreground view.

Kirstenkirsteni

Answer 8

Add android:clickable="true" to rl_bottom_overlay and rl_top_overlay. If you don´t set click events to these layouts (nor via XML neither programatically), no events will be triggered on background views.

// For removing click event, sometime click=true not work

relBottomConfirm.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View view) {
                    return;
                }
            });
