?attr/selectableitembackground Effect Shows Only On Longtap

I've noticed that the effect created by the attribute ?attr/selectableItemBackground only shows when I long tap the view. But I want it to be shown on every tap. View is clickable

Solution 1:

I've noticed there was a change in the behavior between Lollipop and Marshmallow:

• Lollipop - it would start the ripple on press.
• Marshmallow - the ripple starts on release.

Could that be the issue?

I would stick to the device Look & Feel but you could try this suggested solution:

Or use instead a library instead, maybe like this one:

Solution 2:

You can achieve this by setting the background of a view. First of all you have to make an item_selector.xml drawable in drawable and drawable-v21. For drawable folder-

<?xml version="1.0" encoding="utf-8"?><selectorxmlns:android="http://schemas.android.com/apk/res/android"><itemandroid:drawable="@drawable/item_pressed"android:state_focused="true"android:state_pressed="true"/><itemandroid:drawable="@drawable/item_pressed"android:state_focused="false"android:state_pressed="true"/><itemandroid:drawable="@drawable/item_normal"android:state_focused="true"/><itemandroid:drawable="@drawable/item_normal"android:state_focused="false"android:state_pressed="false"/></selector>

For drawable-v21 folder-

<?xml version="1.0" encoding="utf-8"?><ripplexmlns:android="http://schemas.android.com/apk/res/android"android:color="?android:attr/colorControlHighlight" ><item><selectorxmlns:android="http://schemas.android.com/apk/res/android" ><itemandroid:drawable="@drawable/item_pressed"android:state_focused="true"android:state_pressed="true"/><itemandroid:drawable="@drawable/item_pressed"android:state_focused="false"android:state_pressed="true"/><itemandroid:drawable="@drawable/item_normal"android:state_focused="true"/><itemandroid:drawable="@drawable/item_normal"android:state_focused="false"android:state_pressed="false"/></selector></item></ripple>

Now all you need to do is put android:background="@drawable/item_selector" in the view tag. For example-

<LinearLayoutandroid:id="@+id/traveller_select_layout"android:layout_width="match_parent"android:layout_height="wrap_content"android:background="@drawable/item_selector"android:orientation="vertical"android:paddingBottom="10dp"android:paddingTop="5dp"><TextViewandroid:id="@+id/textTravellers"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_marginStart="20dp"android:text="@string/passengers"android:textColor="@color/baggage_grey"android:textSize="12sp"/></LinearLayout>

Now make item_pressed.xml in the drawable folder-

<?xml version="1.0" encoding="utf-8"?><shapexmlns:android="http://schemas.android.com/apk/res/android"android:shape="rectangle" ><solidandroid:color="@color/filter_bg"/></shape>

And the item_normal in the drawable folder-

<?xml version="1.0" encoding="utf-8"?><shapexmlns:android="http://schemas.android.com/apk/res/android"android:shape="rectangle" ><solidandroid:color="@color/white"/></shape>

Solution 3:

Without your code, it's hard to know where goes wrong. But since I have just got this implemented, share with you what I've done, and perhaps you just follow, would help you figure out the issue.

In your view that need the click for ripple

<TextView
     android:id="@+id/your_view_id"
     android:layout_width="match_parent"
     android:layout_height="wrap_content
     android:test="Testing View"
     android:background="@drawable/below_drawable">

In your /drawable-v21 folder, you have your below_drawable.xml with content

<?xml version="1.0" encoding="utf-8"?><ripplexmlns:android="http://schemas.android.com/apk/res/android"android:color="@color/your_click_background_color"><itemandroid:id="@android:id/mask"><shapeandroid:shape="rectagle" ><solidandroid:color="@android:color/your_mask_color" /></shape></item></ripple>

Since the above for Lollipop (v21) only, if you want some impact to your non-lollipop (just show the color, but no ripple). You could have the below in /drawable folder the below_drawable.xml file.

<selectorxmlns:android="http://schemas.android.com/apk/res/android"><itemandroid:state_pressed="true"><shapeandroid:shape="rectangle"><solidandroid:color="@color/your_click_background_color" /></shape></item></selector>

Hope this helps.
