Android – central column in recyclerview
•
Android
I'm trying to create a dynamic recyclerview layout. The gridlayoutmanager I use has three columns
I need to wrap each grid item and center the column (if attached)
I tried a staggeredgridlayout, I tried wrapgridlayoutmanager, but none of these worked
This is my recyclerview:
<android.support.v7.widget.RecyclerView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/categories_grid"
android:layout_marginTop="@dimen/Feed_item_margin"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
And my recyclerview project:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:background="@drawable/first_time_category_unselected"
android:layout_width="wrap_content"
android:layout_height="match_parent">
<TextView
android:id="@+id/category_name"
android:layout_marginLeft="@dimen/Feed_item_margin"
android:layout_gravity="center_vertical"
android:textColor="@color/black_colour"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ImageView
android:id="@+id/category_status_icon"
android:layout_gravity="center_vertical"
android:background="@drawable/icon_follow"
android:layout_marginLeft="@dimen/Feed_item_margin"
android:layout_marginRight="@dimen/Feed_item_margin"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
This is the decoration I use to achieve grid spacing:
public class SpacesItemDecoration extends RecyclerView.ItemDecoration {
private int halfSpace;
public SpacesItemDecoration(int space) {
this.halfSpace = space / 2;
}
@Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
if (parent.getPaddingLeft() != halfSpace) {
parent.setPadding(halfSpace, halfSpace, halfSpace, halfSpace);
parent.setClipToPadding(false);
}
outRect.top = halfSpace;
outRect.bottom = halfSpace;
outRect.left = halfSpace;
outRect.right = halfSpace;
}
}
This is what I want to achieve:
That's what I got:
resolvent:
You can use the staggered grid layout manager
as
StagaggeredGridLayoutManager = new StaggeredGridLayoutManager(3, linearlayoutmanager.HORIZONTAL );
recyclerView.setLayoutManager(gaggeredGridLayoutManager);
