I am trying to make a simple GridLayout with 3 columns, but although I get 3 columns, I have a strange line break. So, I get 3 images per line, than one line that is empty (which apparently has a height matching abov line height (which has images), then a line of 3 images, than a weird space ... and so on. e. I expected to get an empty space. How to remove this empty space? Trying to set wrap_content on layout_height to view recycler, but the fragment did not help. This is my code:
final GridLayoutManager layoutManager = new GridLayoutManager(this,3);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(adapter);
This is the xml of activity:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context="com.adriagate.adriagateonlineandroid.activities.ImagesActivity">
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:id="@+id/fragmentImagesHeader"
android:name="com.adriagate.adriagateonlineandroid.fragments.ImagesHeader"
tools:layout="@layout/fragment_images_header" android:layout_width="match_parent"
android:layout_height="match_parent" >
</fragment>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:id="@+id/fragmentImagesGrid"
android:name="com.adriagate.adriagateonlineandroid.fragments.ImagesList"
tools:layout="@layout/fragment_images_list" android:layout_width="match_parent"
android:layout_height="wrap_content" >
</fragment>
</RelativeLayout>
Note that this layout has an important fragment, called the ImagesGrid fragment, which has this layout:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.adriagate.adriagateonlineandroid.fragments.ImagesList">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view_images"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:listitem="@layout/recycler_view_images_one_row"
>
</FrameLayout>
This is the location of one element in the recycler view:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
xmlns:tools="http://schemas.android.com/tools"
>
<ImageView
android:id="@+id/imageViewImagesAllOneRow"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
tools:src="@drawable/slika_200_200"
/>
</FrameLayout>
