Large Gap Forms Between Recyclerview Items When Scrolling Down

I'm making a ToDo list app, and while testing it, for some reason, a huge gap forms between the items whenever I try to scroll down. It always happens whenever I Drag and Drop the

Solution 1:

Luksprog's answer to Gabriele Mariotti's answer works.

According to the doc

With the release 2.3.0 there is an exciting new feature to the LayoutManager API: auto-measurement! This allows a RecyclerView to size itself based on the size of its contents. >This means that previously unavailable scenarios, such as using WRAP_CONTENT >for a dimension of the RecyclerView, are now possible. You’ll find all built in LayoutManagers now support auto-measurement.

Due to this change, make sure to double check the layout parameters of your item views: previously ignored layout parameters (such as MATCH_PARENT in the scroll direction) will now be fully respected.

In your item layout you have to change:

android:layout_height="match_parent"

with

android:layout_height="wrap_content"

Solution 2:

change in Recycler view match_parent to wrap_content:

<android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

Also change in item layout xml

Make parent layout height match_parent to wrap_content

<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="wrap_content"><TextViewandroid:id="@+id/textView"android:layout_width="wrap_content"android:layout_height="wrap_content"
        />

Solution 3:

This happened to me many times!

All you need to do is... make layout_height of row file wrap_content and your problem solved..

android:layout_height="wrap_content"

Happy coding!

Solution 4:

Its because you are using match_parent in height of root view of the row item in your vertically oriented listview/recyclerview. When you use that the item expands completely wrt to its parent. Use wrap_content for height when the recyclerview is vertically oriented and for width when it is horizantally oriented.

Solution 5:

Avoid taking the view in item layout with a container like this:

<?xml version="1.0" encoding="utf-8"?><layoutxmlns:android="http://schemas.android.com/apk/res/android"><data/><android.support.constraint.ConstraintLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"><TextViewandroid:id="@+id/text"android:layout_width="match_parent"android:layout_height="wrap_content"android:minHeight="?android:listPreferredItemHeight"android:textAppearance="?android:attr/textAppearanceMedium" /></android.support.constraint.ConstraintLayout></layout>

as in this case match_parent will do its work and the problem will still remain! Rather take it like this:

<?xml version="1.0" encoding="utf-8"?><layoutxmlns:android="http://schemas.android.com/apk/res/android"><data/><TextViewandroid:id="@+id/text"android:layout_width="match_parent"android:layout_height="wrap_content"android:minHeight="?android:listPreferredItemHeight"android:textAppearance="?android:attr/textAppearanceMedium" /></layout>

[Note: Above code has data binding attached to it, don't use <layout> & <data> tags if not using data binding]

Other than this, if you must use any view group containers, than take a look the height and width attributes in the container, and try change those from match_parent to wrap_content. That should resolve the issue. For more transparency, one can try giving background colours and see through it to identify actual problem.
